Generalmente, la cantidad de carbono presente var\u00eda de 2-4%. Tambi\u00e9n se encuentra que el silicio es otro elemento de aleaci\u00f3n en el hierro fundido con un porcentaje aproximado de alrededor de 1-3% en peso. La presencia de estos diferentes elementos afecta el color y la calidad del hierro fundido producido. Algunas otras impurezas, como el carburo y el grafito, tambi\u00e9n pueden influir en la aparici\u00f3n de grietas en el metal.<\/p>\n\n\n\n<p>El hierro fundido tiene un punto de fusi\u00f3n m\u00e1s bajo que el elemento hierro. Esto se debe a que el hierro contiene otros materiales como impurezas. Por lo tanto, es f\u00e1cil de moldear. La fundici\u00f3n es una t\u00e9cnica de fabricaci\u00f3n en la que el material l\u00edquido se vierte en moldes y se deja solidificar. El material solidificado se denomina &quot;fundici\u00f3n&quot; y, una vez que se completa la solidificaci\u00f3n, el material se puede retirar del molde. El hierro fundido es un material quebradizo y, a menudo, barato. Tambi\u00e9n tiene un mayor nivel de tolerancia al calor con una alta capacidad t\u00e9rmica. Sin embargo, la conductividad el\u00e9ctrica y t\u00e9rmica es relativamente baja.<\/p>\n\n\n\n<p>El acero est\u00e1 compuesto de hierro como principal metal de aleaci\u00f3n y carbono como segundo componente principal con un porcentaje en peso de alrededor de 2,11 TP3T. La inclusi\u00f3n de elementos como el Cromo permite producir aceros de mejor calidad, como el acero inoxidable. Como su nombre indica, el acero inoxidable es resistente a la corrosi\u00f3n. Esto se debe a que el cromo tiene un mayor potencial de oxidaci\u00f3n que a su vez protege al hierro de la oxidaci\u00f3n al exponerse al aire y la humedad.<\/p>\n\n\n\n<p>El acero posee varias propiedades deseables que lo convierten en un material de construcci\u00f3n adecuado. El acero tiene una viscosidad relativamente alta y es dif\u00edcil de fundir ya que su punto de fusi\u00f3n es m\u00e1s alto que el del hierro fundido. Tambi\u00e9n es m\u00e1s suave que el hierro fundido. A diferencia del hierro fundido, el acero no se rompe f\u00e1cilmente. En cambio, forma astillas cuando se muele y es maleable. El acero tiene m\u00e1s resistencia a la tracci\u00f3n que el hierro fundido. Sin embargo, la resistencia de cada material difiere seg\u00fan el contexto de uso. El acero se utiliza principalmente para la construcci\u00f3n, para vigas y tambi\u00e9n para la producci\u00f3n de utensilios.<\/p>\n\n\n\n<p>El hierro fundido es m\u00e1s barato que el acero y tiene un punto de fusi\u00f3n bajo con la capacidad de moldearse en cualquier forma porque no se encoge cuando se enfr\u00eda. El acero se fabrica con una cantidad controlada de carbono, mientras que el hierro fundido puede tener cualquier cantidad de carbono. Al hierro se le a\u00f1aden carbonos y otros metales como el cromo para formar aleaciones y diferentes calidades o grados de acero, como el acero inoxidable.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Talbe de comparaci\u00f3n entre acero y hierro fundido<\/h2>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><tbody><tr><td><strong>Par\u00e1metros de comparaci\u00f3n<\/strong><\/td><td><strong>Acero<\/strong><\/td><td><strong>Hierro fundido<\/strong><\/td><\/tr><tr><td>Definici\u00f3n<\/td><td>El acero se llama aleaci\u00f3n de hierro.<\/td><td>El hierro fundido es tambi\u00e9n una aleaci\u00f3n de hierro.<\/td><\/tr><tr><td>Presencia de carbono<\/td><td>El acero tiene menos presencia de carbono aproximadamente menos que 2%.<\/td><td>El hierro fundido tiene m\u00e1s de 2% de carbono, aproximadamente m\u00e1s de 4%.<\/td><\/tr><tr><td>Propiedades<\/td><td>D\u00factil y maleable<\/td><td>El movimiento aleatorio de las mol\u00e9culas.<\/td><\/tr><tr><td>forma de carbono<\/td><td>Carburo de hierro<\/td><td>Grafito o carburo de hierro o pueden ser ambos.<\/td><\/tr><tr><td>Punto de fusion<\/td><td>M\u00e1s que hierro fundido<\/td><td>M\u00e1s bajo que el acero.<\/td><\/tr><tr><td>Fluidez<\/td><td>Sin fluidez<\/td><td>Excelente fluidez<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-cast-iron-gate-valve\">V\u00e1lvula de compuerta de hierro fundido<\/h2>\n\n\n\n<p>La v\u00e1lvula de compuerta de hierro fundido es adecuada para encajar entre bridas PN6, PN10\/16 o ANSI 150 (sujeta a configuraci\u00f3n) y est\u00e1 dise\u00f1ada para aplicaciones de uso general, industriales y HVAC; Instalaciones de calefacci\u00f3n de agua fr\u00eda y caliente y donde se requiera un cierre herm\u00e9tico.

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.

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<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\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<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\nAdvantages of Forgings\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:list -->\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.

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.
