Legierter Stahl ist das am h\u00e4ufigsten verwendete Gussmaterial. Gussstahl wird in Kohlenstoffgussstahl, niedriglegierten Gussstahl und Spezialgussstahl unterteilt. Unter Gussstahl versteht man Stahlgussteile, die durch Gussverfahren hergestellt werden. Gussstahl wird haupts\u00e4chlich zur Herstellung von Teilen mit komplexen Formen verwendet, die schwer zu schmieden oder zu schneiden sind und eine hohe Festigkeit und Plastizit\u00e4t erfordern.<\/p>\n\n\n\n Kugelh\u00e4hne aus geschmiedetem Stahl werden im Schmiedeverfahren aus geschmiedetem Stahl und Schmiedeteilen hergestellt. Kugelh\u00e4hne aus geschmiedetem Stahl sind st\u00e4rker als Kugelh\u00e4hne aus Stahlguss und k\u00f6nnen gr\u00f6\u00dferen Aufprallkr\u00e4ften standhalten. Auch ihre Plastizit\u00e4t, Z\u00e4higkeit und andere mechanische Eigenschaften sind h\u00f6her als bei Gussteilen, daher sollten f\u00fcr einige wichtige mechanische Teile geschmiedete Stahlteile verwendet werden.<\/p>\n\n\n\n Beim Gie\u00dfen handelt es sich um eine Fl\u00fcssigkeitsformung, w\u00e4hrend beim Schmieden ein plastischer Verformungsprozess stattfindet. Die innere Struktur des geschmiedeten Werkst\u00fccks wird verbessert, die mechanischen Eigenschaften sind gut, die Maserung ist gleichm\u00e4\u00dfig und es ist die beste Wahl f\u00fcr wichtige Hochleistungsteile. Beim Gie\u00dfen k\u00f6nnen strukturelle Entmischungen und Defekte auftreten, aber das Gie\u00dfen hat seine eigenen Vorteile. Die Formung komplexer Teile ist durch Schmieden nicht so einfach zu erreichen, in diesem Fall ist das Gie\u00dfverfahren vorteilhafter.<\/p>\n\n\n\n\n Zehn Artikel davor und danach<\/p>\n\n\n\n Wie funktioniert ein Absperrventil \u2013 Zeco Valve<\/a><\/p>\n\n\n\n Unterschied zwischen doppelt und dreifach versetztem Absperrventil \u2013 Zeco Valve<\/a><\/p>\n\n\n\n K\u00fckenh\u00e4hne<\/a><\/p>\n\n\n\n Kegel Ventil<\/a><\/p>\n\n\n\n Durchgangsventil<\/a><\/p>\n\n\n\n Einf\u00fchrung von V-Kugelh\u00e4hnen<\/a><\/p>\n\n\n\n Die 5 besten Absperrklappenhersteller in den USA \u2013 Zeco Valve<\/a><\/p>\n\n\n\n Unterschied zwischen Kugelhahn und Absperrklappe \u2013 Zeco Valve<\/a><\/p>\n\n\n\n Frostschutz und Wartung von Ventilen im Winter<\/a><\/p>\n\n\n\n mit den Ventilen<\/a><\/p>","protected":false},"excerpt":{"rendered":" Schmieden und Gie\u00dfen sind zwei sehr unterschiedliche Fertigungsverfahren.

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\r\n\r\n\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. In addition, not every metal is suitable for forging, which limits your options for valve material.\r\n\r\n\r\n\r\n\r\nAdvantages and Disadvantages of Cast Valves\r\n\r\n\r\n\r\n\r\nCast valves are a great option where you need quick turnaround and low-cost valves, as they require less labor to produce. Also, the casting process allows for more complex shapes and valve manufacturing. You also have greater flexibility in material choice, as many types of metals are suitable for casting.\r\n\r\n\r\n\r\n\r\n\r\nWhile cast valves are quite strong and durable when you choose a high-quality manufacturer, there are still some restrictions. For example, the solidification process can create small impurities in the metal.

Forged valves are forged and are generally used in high-grade pipelines with relatively small diameters, generally below DN50.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nGET DIFFERENCE BETWEEN CAST AND FORGED IRONS INFORMATION<\/strong><\/a>\r\n\r\n\r\n\r\n\r\nWhy use Castings?\r\n\r\n\r\n\r\n\r\nWe use castings for a wide range of wear parts and components that are too large, complicated, intricate, or otherwise unsuitable for the forging process. We can forge parts up to 50kgs but the sheer energy required to forge larger items makes casting a much more viable alternative.\r\n\r\n\r\n\r\n\r\nAdvantages of Castings\r\n\r\n\r\n\r\n\r\n \tNo real upper size limit in casting weight\r\n \tLarge range of alloy choices\r\n \tAs forgings remain solid, custom alloys are far more difficult to get into production whereas, with casting, alloys including Chrome, Nickel, and Moly can be added at the molten stage.\r\n \tTooling is often less expensive than forge dies\r\n \tSmaller production \u201cruns\u201d required\r\n \tComplicated\/complex parts are no problem\r\n\r\n\r\n\r\n\r\nWhy use Forgings?\r\n\r\n\r\n\r\n\r\nForging offers uniformity of composition and structure. Forging results in metallurgical recrystallization and grain refinement as a result of the thermal cycle and deformation process. This strengthens the resulting steel product, particularly in terms of impact and shear strength.\r\n\r\n\r\n\r\n\r\n\r\nForged steel is generally stronger and more reliable than castings and plate steel due to the fact that the grain flows of the steel\u00a0are altered, conforming to the shape of the part.\r\n\r\n\r\n\r\n\r\nAdvantages of Forgings\r\n\r\n\r\n\r\n\r\n \tGenerally tougher than alternatives\r\n \tWill handle impact better than castings\r\n \tThe nature of forging excludes the occurrence of porosity, shrinkage, cavities, and cold pour issues.\r\n \tThe tight grain structure of forgings makes them mechanically strong. There is less need for expensive alloys to attain high-strength components.\r\n \tThe tight grain structure offers great wear resistance without the need to make products \u201csuperhard\u201d We have found that on a blank HRC 38-42 forged grinder insert wear\/wash is about the same as a high alloy HRC 46-50 cast grinder insert. The difference being an HRC 46-50 casting does not have the ductility to handle high-impact grinding.\r\n\r\n\r\n\r\n\r\nDifference Between Cast and Forged Irons\r\n\r\n\r\n\r\n\r\nCasting valve: the metal is smelted into a liquid that meets the requirements and poured into the specified valve mold. 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\r\n\r\n\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\r\n\r\n\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\r\n\r\n\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","parent":0,"count":7,"filter":"raw"},{"term_id":3453,"name":"forged in steel cast","slug":"forged-in-steel-cast","term_group":0,"term_taxonomy_id":3453,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3451,"name":"forged steel ball valves","slug":"forged-steel-ball-valves","term_group":0,"term_taxonomy_id":3451,"taxonomy":"post_tag","description":"","parent":0,"count":3,"filter":"raw"},{"term_id":3449,"name":"forged steel vs cast steel","slug":"forged-steel-vs-cast-steel","term_group":0,"term_taxonomy_id":3449,"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":"\r\n\r\n\r\n\r\nGET FORGED VS CAST IRONS INFORMATION<\/strong><\/a>\r\n\r\n\r\n\r\n\r\nKugelhahn aus geschmiedetem Stahl vs. Kugelhahn aus Gussstahl<\/h2>\n\n\n\n

Forged<\/h2>\r\n\r\n\r\n\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\r\n\r\n\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\r\n\r\n\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\r\n\r\n\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\r\n\r\n\r\n
Cast Irons<\/h2>\r\n\r\n\r\n\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\r\n\r\n\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\r\n\r\n\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\r\n\r\n\r\n
Manufacturing Process Forged vs Cast Irons<\/h2>\r\n\r\n\r\n\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\r\n\r\n\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\r\n\r\n\r\n
Forging is stronger than casting.<\/h2>\r\n\r\n\r\n\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. According to a study performed by the Industrial & Manufacturing Engineering Department at the University of Toledo:\r\n\r\n\r\n\r\n\r\n
\r\n \t
