G\u00e9n\u00e9ralement, la quantit\u00e9 de carbone pr\u00e9sente varie de 2 \u00e0 4%. Le silicium s&#039;av\u00e8re \u00e9galement \u00eatre un autre \u00e9l\u00e9ment d&#039;alliage dans la fonte avec un pourcentage approximatif d&#039;environ 1-3% en poids. La pr\u00e9sence de ces diff\u00e9rents \u00e9l\u00e9ments affecte la couleur et la qualit\u00e9 de la fonte produite. Certaines autres impuret\u00e9s telles que le carbure et le graphite peuvent \u00e9galement influencer l&#039;initiation de fissures dans le m\u00e9tal.<\/p>\n\n\n\n<p>La fonte a un point de fusion inf\u00e9rieur \u00e0 celui de l\u2019\u00e9l\u00e9ment fer. En effet, le fer contient d\u2019autres mati\u00e8res sous forme d\u2019impuret\u00e9s. Il est donc facile de le couler dans des moules. Le moulage est une technique de fabrication o\u00f9 la mati\u00e8re liquide est coul\u00e9e dans des moules et laiss\u00e9e se solidifier. Le mat\u00e9riau solidifi\u00e9 est appel\u00e9 \u00ab coul\u00e9e \u00bb et, une fois la solidification termin\u00e9e, le mat\u00e9riau peut \u00eatre retir\u00e9 du moule. La fonte est un mat\u00e9riau fragile et souvent bon march\u00e9. Il pr\u00e9sente \u00e9galement un niveau de tol\u00e9rance thermique plus \u00e9lev\u00e9 et une capacit\u00e9 thermique \u00e9lev\u00e9e. Cependant, la conductivit\u00e9 \u00e9lectrique et thermique est relativement faible.<\/p>\n\n\n\n<p>L&#039;acier est compos\u00e9 de fer comme principal m\u00e9tal d&#039;alliage et de carbone comme deuxi\u00e8me composant principal avec un pourcentage pond\u00e9ral d&#039;environ 2,11 TP3T. L\u2019inclusion d\u2019\u00e9l\u00e9ments tels que le chrome permet de produire des qualit\u00e9s d\u2019acier de meilleure qualit\u00e9, comme l\u2019acier inoxydable. Comme son nom l\u2019indique, l\u2019acier inoxydable r\u00e9siste \u00e0 la corrosion. En effet, le chrome a un potentiel d\u2019oxydation plus \u00e9lev\u00e9, ce qui emp\u00eache le fer de s\u2019oxyder lors de l\u2019exposition \u00e0 l\u2019air et \u00e0 l\u2019humidit\u00e9.<\/p>\n\n\n\n<p>L&#039;acier poss\u00e8de plusieurs propri\u00e9t\u00e9s souhaitables qui en font un mat\u00e9riau de construction appropri\u00e9. L&#039;acier a une viscosit\u00e9 relativement \u00e9lev\u00e9e et est difficile \u00e0 couler car son point de fusion est plus \u00e9lev\u00e9 que la fonte. Elle est \u00e9galement plus douce que la fonte. Contrairement \u00e0 la fonte, l\u2019acier ne se brise pas facilement. Au lieu de cela, il forme des copeaux lorsqu\u2019il est broy\u00e9 et est mall\u00e9able. L&#039;acier a une plus grande r\u00e9sistance \u00e0 la traction que la fonte. Cependant, la r\u00e9sistance de chaque mat\u00e9riau diff\u00e8re selon le contexte d\u2019utilisation. L&#039;acier est principalement utilis\u00e9 pour la construction, pour les poutres et aussi pour la production d&#039;ustensiles.<\/p>\n\n\n\n<p>La fonte est moins ch\u00e8re que l&#039;acier et elle a un point de fusion bas et peut prendre n&#039;importe quelle forme car elle ne r\u00e9tr\u00e9cit pas lorsqu&#039;elle refroidit. L&#039;acier est fabriqu\u00e9 avec une quantit\u00e9 contr\u00f4l\u00e9e de carbone, tandis que la fonte peut contenir n&#039;importe quelle quantit\u00e9 de carbone. Des carbones et d&#039;autres m\u00e9taux comme le chrome sont ajout\u00e9s au fer pour fabriquer des alliages et diff\u00e9rentes qualit\u00e9s ou nuances d&#039;acier, comme l&#039;acier inoxydable.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Talbe de comparaison entre l&#039;acier et la fonte<\/h2>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><tbody><tr><td><strong>Param\u00e8tres de comparaison<\/strong><\/td><td><strong>Acier<\/strong><\/td><td><strong>Fonte<\/strong><\/td><\/tr><tr><td>D\u00e9finition<\/td><td>L&#039;acier est appel\u00e9 un alliage de fer.<\/td><td>La fonte est \u00e9galement un alliage de fer.<\/td><\/tr><tr><td>Pr\u00e9sence de carbone<\/td><td>L&#039;acier contient moins de carbone, environ moins que le 2%.<\/td><td>La fonte contient plus de 2% de carbone, soit environ plus de 4%.<\/td><\/tr><tr><td>Propri\u00e9t\u00e9s<\/td><td>Ductile et mall\u00e9able<\/td><td>Le mouvement al\u00e9atoire des mol\u00e9cules.<\/td><\/tr><tr><td>Forme de carbone<\/td><td>Carbure de fer<\/td><td>Graphite ou carbure de fer ou peut \u00eatre les deux.<\/td><\/tr><tr><td>Point de fusion<\/td><td>Plus que de la fonte<\/td><td>Inf\u00e9rieur \u00e0 l&#039;acier.<\/td><\/tr><tr><td>Fluidit\u00e9<\/td><td>Aucune fluidit\u00e9<\/td><td>Excellente fluidit\u00e9<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-cast-iron-gate-valve\">Vanne \u00e0 vanne en fonte<\/h2>\n\n\n\n<p>Le robinet-vanne en fonte convient pour s&#039;adapter entre les brides PN6, PN10\/16 ou ANSI 150 (sous r\u00e9serve de configuration) et est con\u00e7u pour les applications g\u00e9n\u00e9rales, industrielles et CVC ; installations de chauffage \u00e0 eau chaude et froide et o\u00f9 une fermeture \u00e9tanche est requise.

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. In addition, not every metal is suitable for forging, which limits your options for valve material.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\nAdvantages and Disadvantages of Cast Valves\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\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<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\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. They also are less resistant to high temperatures and pressures compared to a forged ball valve.\r\n\r\n<!-- \/wp:paragraph -->","parent":0,"count":7,"filter":"raw"},{"term_id":3265,"name":"Difference Between Forged and Cast","slug":"difference-between-forged-and-cast","term_group":0,"term_taxonomy_id":3265,"taxonomy":"post_tag","description":"<!-- wp:paragraph -->\r\n\r\nCasting valves are valves made by casting. Generally, the pressure grades of cast valves are relatively low (such as PN16, PN25, and PN40, but there are also high-pressure ones, which can reach 1500Lb, and 2500Lb), and most of their calibers are above DN50.

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.
