Obwohl die Form meistens eine Matrize ist, werden Sand- und Feingussverfahren h\u00e4ufig f\u00fcr bestimmte Legierungen oder f\u00fcr Teile mit ungew\u00f6hnlichen Abmessungen und Designs verwendet. Sobald das Metall in die gew\u00fcnschte Grundform abgek\u00fchlt ist, veredelt der Metallarbeiter das Teil mit den vom Kunden gew\u00fcnschten Details entweder von Hand oder durch weitere Bearbeitung.<\/p>\n\n\n\n<p><span style=\"font-family: arial, helvetica, sans-serif; font-size: small;\">Die Kosten f\u00fcr die Herstellung von Gussrohlingen sind gering, bei komplexen Formen, insbesondere bei komplexen Hohlr\u00e4umen, kann sich die Wirtschaftlichkeit noch weiter auszahlen.

Chr. tauchten in Mesopotamien Gussst\u00fccke von bronzenen Fr\u00f6schen auf. Zwischen dem 13. und 10. Jahrhundert v. Chr. erlebte China die Bl\u00fctezeit des Bronzegusses, und das Verfahren erreichte ein ziemlich hohes Niveau. So sind etwa der 875 kg schwere quadratische Simuwu-Ding aus der Shang-Dynastie, der Jinghou Yi Zunpan aus der Dynastie der Streitenden Reiche und der transparente Spiegel aus der Westlichen Han-Dynastie repr\u00e4sentative Produkte des antiken Gusses. Der fr\u00fche Guss war stark von der T\u00f6pferei beeinflusst, und die meisten Gussst\u00fccke waren Werkzeuge oder Utensilien f\u00fcr die landwirtschaftliche Produktion, die Religion, das Leben und andere Aspekte mit starker k\u00fcnstlerischer Farbigkeit. 513 v. Chr. produzierte China das erste Gusseisen, das in schriftlichen Aufzeichnungen der Welt erw\u00e4hnt wird \u2013 das Jin-Gussst\u00fcck (etwa 270 kg). Um das 8. Jahrhundert begann Europa mit der Gusseisenproduktion. Nach der industriellen Revolution im 18. Jahrhundert traten Gussst\u00fccke in eine neue Phase der Versorgung gro\u00dfer Industrien ein. Im 20. Jahrhundert entwickelte sich das Gie\u00dfen rasant. Sph\u00e4roguss, Temperguss, Edelstahl mit ultraniedrigem Kohlenstoffgehalt sowie Aluminiumkupfer, Aluminiumsilizium, Aluminiummagnesiumlegierungen, Titanbasis, Nickelbasislegierungen und andere Gussmetallmaterialien wurden entwickelt und ein neues Verfahren zur Behandlung von Grauguss erfunden. Nach den 1950er Jahren wurden neue Technologien wie Nasssand-Hochdruckformen, chemisch geh\u00e4rtetes Sandformen, Kernherstellung, Unterdruckformen und andere spezielle Guss- und Kugelstrahlverfahren eingef\u00fchrt.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Arten des Gie\u00dfens<\/h2>\n\n\n\n<p><span style=\"font-family: arial, helvetica, sans-serif; font-size: small;\">Es gibt viele Arten von Gussformen.

Das Gie\u00dfen kann je nach Material in Sandformen, Metall, Keramik, Schlamm, Graphit usw. unterteilt werden und kann nach Verwendung in Einweg-, halbpermanente und permanente Typen unterteilt werden. Die Qualit\u00e4t der Formvorbereitung ist der Hauptfaktor, der die Gussqualit\u00e4t beeinflusst. Das Schmelzen und Gie\u00dfen von Gussmetall. Gussmetall (Gusslegierung) umfasst haupts\u00e4chlich Gusseisen, Stahlguss und Nichteisengusslegierungen. (3) Gussbehandlung und -pr\u00fcfung. Die Gussbehandlung umfasst das Entfernen von Fremdk\u00f6rpern im Kern und an der Gussoberfl\u00e4che, das Entfernen von Gusssteigrohren, das Schleifen von Graten und anderen Vorspr\u00fcngen mit der Schaufel, W\u00e4rmebehandlung, Formgebung, Rostschutzbehandlung und Grobbearbeitung.

Stattdessen wird es nur hei\u00df genug gemacht, damit der Metallarbeiter es durch Hammerschmieden oder auf andere Weise in eine vorbereitete Matrize bringen kann. F\u00fcr gr\u00f6\u00dfere Produkte werden riesige Pressen verwendet und die Schmiedemethode kann je nach gew\u00fcnschtem Endprodukt variieren.

Der Metallrohling wird in der Schmiedekammer einer bestimmten Form unter Druck verformt. Das Schmieden kann in Gesenkschmieden, Kaltschmieden, Rotationsschmieden, Extrusion usw. unterteilt werden. Je nach Verformungstemperatur kann das Schmieden in Warmschmieden (die Verarbeitungstemperatur ist h\u00f6her als die Rekristallisationstemperatur des Rohlings), Warmschmieden (niedriger als die Rekristallisationstemperatur) und Kaltschmieden (normale Temperatur) unterteilt werden.<\/span><\/p>\n\n\n\n<p><span style=\"font-family: arial, helvetica, sans-serif; font-size: small;\">Das Schmiedematerial besteht haupts\u00e4chlich aus verschiedenen Komponenten aus Kohlenstoffstahl und legiertem Stahl, gefolgt von Aluminium, Magnesium, Titan, Kupfer und seinen Legierungen.

After cooling, solidification, and cleaning, a valve casting with a predetermined shape, size, and performance can be obtained. This is the entire casting valve crafting process. The connection between casting and valves came after the 20th century. Casting developed rapidly, creating ductile cast iron, malleable cast iron, ultra-low carbon stainless steel, aluminum copper, aluminum silicon, aluminum-magnesium alloy, and titanium which are still often used in valve products.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nCast metal materials such as base, nickel base alloy, etc. The main advantage of casting is that the cost of the blank produced by casting is low, and it can show its economy more for parts with complex shapes, especially with complex inner cavities. At the same time, it has wider adaptability and better comprehensive mechanical properties. However, many materials and equipment are required for casting production, and dust, harmful gases, and noise will be generated to pollute the environment.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nForged valve is a processing method that uses forging machinery to apply pressure to metal valve blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes, and sizes. Forging can be divided into open forging (free forging) and closed mode forging according to the forming method. According to the deformation temperature, forging can be divided into hot forging, warm forging, and cold forging.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nForging materials are mainly carbon steel and alloy steel with various compositions, followed by aluminum, magnesium, titanium, copper, etc., and their alloys. The original state of the material includes bar stock, ingot, metal powder, and liquid metal. The ratio of the cross-sectional area of the metal before deformation to the die cross-sectional area after deformation is called the forging ratio. Through forging, the as-cast looseness of metal and welding holes can be eliminated, and the mechanical properties of forgings are generally better than those of castings of the same material. For the important parts of machinery with high loads and severe working conditions, forgings are mostly used except for simpler shapes that can be rolled, profiles or welded parts. The correct selection of forging ratios has a great bearing on improving product quality and reducing costs.\r\n\r\n<!-- \/wp:paragraph -->","parent":0,"count":7,"filter":"raw"},{"term_id":3266,"name":"difference between forged and cast irons","slug":"difference-between-forged-and-cast-irons","term_group":0,"term_taxonomy_id":3266,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3263,"name":"forged vs cast","slug":"forged-vs-cast","term_group":0,"term_taxonomy_id":3263,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3264,"name":"Forged vs Cast Irons","slug":"forged-vs-cast-irons","term_group":0,"term_taxonomy_id":3264,"taxonomy":"post_tag","description":"<!-- wp:kadence\/tableofcontents {\"uniqueID\":\"_4feb50-82\"} \/-->\r\n\r\n<!-- wp:generateblocks\/button-container {\"uniqueId\":\"6d8495a3\",\"isDynamic\":true,\"blockVersion\":2} -->\r\n<!-- wp:generateblocks\/button {\"uniqueId\":\"3d442e11\",\"hasUrl\":true,\"target\":true,\"backgroundColor\":\"#0366d6\",\"textColor\":\"#ffffff\",\"backgroundColorHover\":\"#222222\",\"textColorHover\":\"#ffffff\",\"paddingTop\":\"15\",\"paddingRight\":\"20\",\"paddingBottom\":\"15\",\"paddingLeft\":\"20\"} -->\r\n<a class=\"gb-button gb-button-3d442e11 gb-button-text\" href=\"mailto:commercial@zecovalve.com\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>GET FORGED VS CAST IRONS INFORMATION<\/strong><\/a>\r\n<!-- \/wp:generateblocks\/button -->\r\n<!-- \/wp:generateblocks\/button-container -->\r\n\r\n<!-- wp:heading -->\r\n<h2 id=\"h-forged\">Forged<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nForging refers to a process in which a material is usually heated, while maintaining a solid state, and then forced into the shape desired. Now to explain better, we must put on our material engineering hats.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nMetals have a crystalline structure. You can think of it like wood. Wood has grains and those grains are oriented in a certain pattern. Therefore, the strength of wood depends on how those grains are oriented. For example, it is much easier to splinter a log for firewood when the grains are oriented vertically. Metal is the same way. If you examine metal under a microscope it will have the same grains that you associate with wood.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nWhen metal ingots are formed, special attention is made to creating a uniform and consistent crystalline structure. The grain sizes are similar and flow together. As previously stated, this maximizes the strength, consistency, and durability of the metal.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nNow when you forge something out of that metal ingot, you heat the ingot to make it malleable but not enough to break apart the crystalline grain structure. Think of a blacksmith. Blacksmiths heat metal till it's red hot and then form it on an anvil. This is forging. You do not see them melting the metal into a liquid. By keeping the metal, solid throughout the entire process, it ends up being a much stronger object. Therefore, swords, knives, etc. have historically been forged.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Cast Irons<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nCasting an object requires building a mold and pouring liquid metal into it. This process is great, as it allows for easy manufacturing and the creation of complex parts with hollow chambers such as with an engine block of a vehicle. The manufacturer can use a meltable material such as wax inside a sand mold to form these complex shapes.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nUnfortunately, once the metal becomes a liquid the crystalline grain structure breaks down. As a newly formed cast object cools down and becomes solid again, the grain structure reforms but this time much more randomly and inconsistently. There also is the potential for trapped air to create weak points. The metal becomes more like particle board or cardboard in terms of structure than a normal piece of wood.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nNow does this make cast parts weak? Absolutely not. Over the past couple thousand years, humans have gotten pretty good at making cast metal parts. Ventilation holes, vacuum pressure, and other advances increase the quality of cast metal. As stated, cast metal is what vehicle engine blocks are made from those are expected to withstand extreme stress and strain.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Manufacturing Process Forged vs Cast Irons<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe first thing to know is that \"cast\" and \"forged\" are nothing more than terms describing the manufacturing process of iron or a set of irons.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe casting process: When a golf iron is cast, the metal used to make the iron is heated to its melting point, becoming a liquid.

When it cools and hardens, voila, you have golf irons.\r\nThe forging process: When a golf iron is forged, the solid metal of the club head is literally pounded or compressed until it takes the desired shape.

In the 1930s, American companies made the world\u2019s first shot-blasting machine. The production of shot blasting equipment in China began in the 1950s and was largely based on Soviet technology.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>What is Shot Blasting Machine Used For?<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nWheel blast machines can also be used to remove burrs, diaphragms, and rust that may affect the integrity, appearance, or definition of an object\u2019s parts. The machine can also target a partially coated surface to remove surface contaminants and provide a surface profile that increases the coating\u2019s adhesion to the surface for the purpose of shot-blasting the workpiece. A shot peening machine differs from a wheel blasting machine in that it is used to reduce the fatigue life of a part by increasing different surface stresses, increasing the strength of a part, or preventing micromotion. Shot blasting machines are primarily used to treat the surface of steel products in large quantities during the steel production process. The use of a shot blasting machine can effectively remove burrs on the surface of steel products, as well as some large-scale rust, in the use of shot blasting machines, if not mastering the technology, is likely to cause the integrity of the surface of steel products, the light will cause surface abrasions, and serious will cause a serious poor appearance, affecting the product image.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nFor steel production, a shot blasting machine is inevitable equipment, and the use of a shot blasting machine for steel sand as well as steel shot surface treatment, is also an essential process, as the removal of steel sand, steel shot surface stains, rust, and a necessary procedure to check the integrity of the product surface, is essential.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Functions of Shot Blasting Machine<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nCan remove the cast steel, cast iron surface of the oxide skin or sticky sand, the surface of the casting to play a role in cleaning, but also the quality of the castings for inspection of a necessary step, the large turbine casing to go in front of the line after shot blasting to detect injuries, so as to ensure reliable results. Hook-type blast machine is divided into single-hook and double-hook, hook-type blast machines by two hook-loading workpieces alternately into the blast cleaning room. The shot blast machine is used to throw 0.2 to 0.8 pellets to the surface of the workpiece, making the surface of the workpiece to a certain roughness, making the workpiece beautiful, or changing the compressive stress of the workpiece to improve the life of the workpiece.
