Im Allgemeinen variiert die vorhandene Kohlenstoffmenge zwischen 2 und 4%. Silizium ist ein weiteres Legierungselement in Gusseisen mit einem ungef\u00e4hren Gewichtsanteil von etwa 1 bis 3%. Das Vorhandensein dieser verschiedenen Elemente beeinflusst die Farbe und die Qualit\u00e4t des hergestellten Gusseisens. Bestimmte andere Verunreinigungen wie Karbid und Graphit k\u00f6nnen ebenfalls die Entstehung von Rissen im Metall beeinflussen.<\/p>\n\n\n\n<p>Gusseisen hat einen niedrigeren Schmelzpunkt als das Element Eisen. Dies liegt daran, dass Eisen andere Materialien als Verunreinigungen enth\u00e4lt. Daher kann es leicht in Formen gegossen werden. Gie\u00dfen ist eine Fertigungstechnik, bei der das fl\u00fcssige Material in Formen gegossen und erstarren gelassen wird. Das erstarrte Material wird als \u201eGussteil\u201c bezeichnet und kann nach Abschluss der Erstarrung aus der Form entfernt werden. Gusseisen ist ein spr\u00f6des Material, das oft billig ist. Es hat auch eine h\u00f6here Hitzetoleranz und eine hohe W\u00e4rmekapazit\u00e4t. Die elektrische und thermische Leitf\u00e4higkeit ist jedoch relativ gering.<\/p>\n\n\n\n<p>Stahl besteht aus Eisen als Hauptlegierungsmetall und Kohlenstoff als wichtigstem Zweitbestandteil mit einem Gewichtsanteil von etwa 2,1%. Die Einbeziehung von Elementen wie Chrom erm\u00f6glicht die Herstellung hochwertigerer Stahlsorten wie Edelstahl. Wie der Name schon sagt, ist Edelstahl korrosionsbest\u00e4ndig. Dies liegt daran, dass Chrom ein h\u00f6heres Oxidationspotenzial hat, das wiederum das Eisen vor Oxidation bei Kontakt mit Luft und Feuchtigkeit sch\u00fctzt.<\/p>\n\n\n\n<p>Stahl besitzt mehrere w\u00fcnschenswerte Eigenschaften, die ihn zu einem geeigneten Baumaterial machen. Stahl hat eine relativ hohe Viskosit\u00e4t und l\u00e4sst sich schwer gie\u00dfen, da sein Schmelzpunkt h\u00f6her ist als bei Gusseisen. Au\u00dferdem ist er weicher als Gusseisen. Im Gegensatz zu Gusseisen bricht Stahl nicht so leicht. Stattdessen bildet er beim Schleifen Sp\u00e4ne und ist formbar. Stahl hat eine h\u00f6here Zugfestigkeit als Gusseisen. Die Festigkeit der einzelnen Materialien ist jedoch je nach Verwendungszweck unterschiedlich. Stahl wird haupts\u00e4chlich f\u00fcr den Bau, f\u00fcr Balken und auch f\u00fcr die Herstellung von Gebrauchsgegenst\u00e4nden verwendet.<\/p>\n\n\n\n<p>Gusseisen ist billiger als Stahl, hat einen niedrigen Schmelzpunkt und kann in jede beliebige Form gebracht werden, da es beim Abk\u00fchlen nicht schrumpft. Stahl wird mit einer kontrollierten Menge Kohlenstoff hergestellt, w\u00e4hrend Gusseisen jede beliebige Menge Kohlenstoff enthalten kann. Kohlenstoffe und andere Metalle wie Chrom werden dem Eisen zugesetzt, um Legierungen und verschiedene Stahlqualit\u00e4ten oder -sorten wie Edelstahl herzustellen.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Vergleichstabelle zwischen Stahl und Gusseisen<\/h2>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><tbody><tr><td><strong>Vergleichsparameter<\/strong><\/td><td><strong>Stahl<\/strong><\/td><td><strong>Gusseisen<\/strong><\/td><\/tr><tr><td>Definition<\/td><td>Als Stahl bezeichnet man eine Eisenlegierung.<\/td><td>Gusseisen ist ebenfalls eine Eisenlegierung.<\/td><\/tr><tr><td>Vorhandensein von Kohlenstoff<\/td><td>Stahl hat einen geringeren Kohlenstoffgehalt, etwa weniger als 2%.<\/td><td>Gusseisen hat einen Kohlenstoffgehalt von mehr als 21 TP3T, ungef\u00e4hr mehr als 41 TP3T.<\/td><\/tr><tr><td>Eigenschaften<\/td><td>Duktil und formbar<\/td><td>Die zuf\u00e4llige Bewegung von Molek\u00fclen.<\/td><\/tr><tr><td>Form von Kohlenstoff<\/td><td>Eisenkarbid<\/td><td>Graphit oder Eisenkarbid oder beides.<\/td><\/tr><tr><td>Schmelzpunkt<\/td><td>Mehr als Gusseisen<\/td><td>Niedriger als Stahl.<\/td><\/tr><tr><td>Fl\u00fcssigkeit<\/td><td>Keine Flie\u00dff\u00e4higkeit<\/td><td>Ausgezeichnete Flie\u00dff\u00e4higkeit<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-cast-iron-gate-valve\">Absperrschieber aus Gusseisen<\/h2>\n\n\n\n<p>Das Absperrventil aus Gusseisen passt zwischen Flansche PN6, PN10\/16 oder ANSI 150 (je nach Konfiguration) und ist f\u00fcr allgemeine Zwecke, industrielle und HVAC-Anwendungen konzipiert; Warm- und Kaltwasserheizungsanlagen und \u00fcberall dort, wo eine dichte Absperrung erforderlich ist.

reasons why you may want a forged ball valve for your application instead of a cast valve. Forged valves do tend to be better for high-temperature and high-pressure applications. These types of valves are less prone to thermal fatigue because the walls are thinner compared to cast alternatives. Also, forged options have a higher mass, making them mechanically stronger.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nHowever, there are a few reasons why a forged ball valve may not be best for your application. First, the forging process does create limitations for valve size and shape. Forging generally works better for smaller valves and components.

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":3248,"name":"difference between steel and cast iron","slug":"difference-between-steel-and-cast-iron","term_group":0,"term_taxonomy_id":3248,"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. It is then poured into the molds of the iron heads. 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. After that, a number of other drilling and machining steps take place to finish the manufacturing process.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Forging is stronger than casting.<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nOne of the main reasons we choose to provide forging services is that it provides a stronger end product for our partners.
