Generalmente, los grados de presi\u00f3n de las v\u00e1lvulas fundidas son relativamente bajos (como PN16, PN25 y PN40, pero tambi\u00e9n hay v\u00e1lvulas de alta presi\u00f3n, que pueden alcanzar 1500 Lb y 2500 Lb), y la mayor\u00eda de sus calibres est\u00e1n por encima de DN50. Las v\u00e1lvulas forjadas est\u00e1n forjadas y generalmente se utilizan en tuber\u00edas de alta calidad con di\u00e1metros relativamente peque\u00f1os, generalmente por debajo de DN50.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nOBTENER INFORMACI\u00d3N SOBRE LA DIFERENCIA ENTRE HIERROS FUNDIDOS Y FORJADOS<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n\u00bfPor qu\u00e9 utilizar Castings?\r\n\r\n\r\n\r\n\r\nUtilizamos piezas fundidas para una amplia gama de piezas y componentes de desgaste que son demasiado grandes, complicados, intrincados o inadecuados para el proceso de forjado. Podemos forjar piezas de hasta 50 kg, pero la enorme energ\u00eda necesaria para forjar piezas m\u00e1s grandes hace que la fundici\u00f3n sea una alternativa mucho m\u00e1s viable.\r\n\r\n\r\n\r\n\r\nVentajas de las piezas fundidas\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\n\u00bfPor qu\u00e9 utilizar forjas?\r\n\r\n\r\n\r\n\r\nLa forja ofrece uniformidad de composici\u00f3n y estructura. La forja da como resultado la recristalizaci\u00f3n metal\u00fargica y el refinamiento del grano como resultado del ciclo t\u00e9rmico y el proceso de deformaci\u00f3n. Esto fortalece el producto de acero resultante, particularmente en t\u00e9rminos de resistencia al impacto y al corte.\r\n\r\n\r\n\r\n\r\n\r\nEl acero forjado es generalmente m\u00e1s resistente y confiable que las piezas fundidas y las placas de acero debido al hecho de que los flujos de grano del acero se modifican, adapt\u00e1ndose a la forma de la pieza.\r\n\r\n\r\n\r\n\r\nVentajas de las forjas\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.

Despu\u00e9s de enfriar, solidificar y limpiar, se puede obtener una v\u00e1lvula fundida con una forma, tama\u00f1o y rendimiento predeterminados. Este es todo el proceso de elaboraci\u00f3n de la v\u00e1lvula de fundici\u00f3n. La conexi\u00f3n entre fundici\u00f3n y v\u00e1lvulas se produjo despu\u00e9s del siglo XX. La fundici\u00f3n se desarroll\u00f3 r\u00e1pidamente, creando hierro fundido d\u00factil, hierro fundido maleable, acero inoxidable con contenido de carbono ultra bajo, cobre de aluminio, silicio de aluminio, aleaci\u00f3n de aluminio y magnesio y titanio, que todav\u00eda se utilizan con frecuencia en productos de v\u00e1lvulas.\r\n\r\n\r\n\r\n\r\n\r\nMateriales met\u00e1licos fundidos como base, aleaciones a base de n\u00edquel, etc. La principal ventaja de la fundici\u00f3n es que el costo de la pieza en bruto producida por fundici\u00f3n es bajo y puede mostrar su econom\u00eda m\u00e1s para piezas con formas complejas, especialmente con cavidades internas complejas. Al mismo tiempo, tiene una mayor adaptabilidad y mejores propiedades mec\u00e1nicas integrales. Sin embargo, se requieren muchos materiales y equipos para la producci\u00f3n de piezas fundidas, y se generar\u00e1 polvo, gases nocivos y ruido que contaminar\u00e1n el medio ambiente.\r\n\r\n\r\n\r\n\r\n\r\nLa v\u00e1lvula forjada es un m\u00e9todo de procesamiento que utiliza maquinaria de forja para aplicar presi\u00f3n a los espacios en blanco de v\u00e1lvulas met\u00e1licas para producir deformaci\u00f3n pl\u00e1stica y obtener piezas forjadas con ciertas propiedades mec\u00e1nicas, ciertas formas y tama\u00f1os. La forja se puede dividir en forja abierta (forja libre) y forja en modo cerrado seg\u00fan el m\u00e9todo de formaci\u00f3n. Seg\u00fan la temperatura de deformaci\u00f3n, la forja se puede dividir en forja en caliente, forja en caliente y forja en fr\u00edo.\r\n\r\n\r\n\r\n\r\n\r\nLos materiales de forja son principalmente acero al carbono y aceros aleados de diversas composiciones, seguidos del aluminio, magnesio, titanio, cobre, etc., y sus aleaciones. El estado original del material incluye barras, lingotes, polvo met\u00e1lico y metal l\u00edquido. La relaci\u00f3n entre el \u00e1rea de la secci\u00f3n transversal del metal antes de la deformaci\u00f3n y el \u00e1rea de la secci\u00f3n transversal del troquel despu\u00e9s de la deformaci\u00f3n se denomina relaci\u00f3n de forjado. Mediante la forja, se puede eliminar la holgura del metal y de los orificios de soldadura, y las propiedades mec\u00e1nicas de las piezas forjadas son generalmente mejores que las de las piezas fundidas del mismo material. Para las partes importantes de la maquinaria con cargas elevadas y condiciones de trabajo severas, se utilizan principalmente piezas forjadas, excepto en el caso de formas m\u00e1s simples que pueden ser piezas laminadas, perfiladas o soldadas. La correcta selecci\u00f3n de las relaciones de forjado tiene una gran influencia en la mejora de la calidad del producto y la reducci\u00f3n de costes.\r\n\r\n","link":"https:\/\/zecovalve.com\/es\/tag\/difference-between-forged-and-cast","name":"Diferencia entre forjado y fundido","slug":"difference-between-forged-and-cast","taxonomy":"post_tag","meta":[],"yoast_head":"\nDifference Between Forged and Cast Irons Valve | ZECO Valve<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/zecovalve.com\/es\/tag\/difference-between-forged-and-cast\" \/>\n<meta property=\"og:locale\" content=\"es_ES\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Difference Between Forged and Cast Irons Valve | ZECO Valve\" \/>\n<meta property=\"og:description\" content=\"Casting 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. Forged valves are forged and are generally used in high-grade pipelines with relatively small diameters, generally below DN50. GET DIFFERENCE BETWEEN CAST AND FORGED IRONS INFORMATION Why use Castings? We 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. Advantages of Castings No real upper size limit in casting weight Large range of alloy choices As 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. Tooling is often less expensive than forge dies Smaller production \u201cruns\u201d required Complicated\/complex parts are no problem Why use Forgings? Forging 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. Forged 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. Advantages of Forgings Generally tougher than alternatives Will handle impact better than castings The nature of forging excludes the occurrence of porosity, shrinkage, cavities, and cold pour issues. The tight grain structure of forgings makes them mechanically strong. There is less need for expensive alloys to attain high-strength components. The 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. Difference Between Cast and Forged Irons Casting 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. Cast 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. Forged 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. Forging 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.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/zecovalve.com\/es\/tag\/difference-between-forged-and-cast\" \/>\n<meta property=\"og:site_name\" content=\"ZECO Valve\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"WebSite\",\"@id\":\"https:\/\/zecovalve.com\/#website\",\"url\":\"https:\/\/zecovalve.com\/\",\"name\":\"ZECO Valve\",\"description\":\"Industrial Ball Valve, Gate Valve and Globe Valve Manufacturer\",\"potentialAction\":[{\"@type\":\"SearchAction\",\"target\":\"https:\/\/zecovalve.com\/?s={search_term_string}\",\"query-input\":\"required name=search_term_string\"}],\"inLanguage\":\"es\"},{\"@type\":\"CollectionPage\",\"@id\":\"https:\/\/zecovalve.com\/tag\/difference-between-forged-and-cast#webpage\",\"url\":\"https:\/\/zecovalve.com\/tag\/difference-between-forged-and-cast\",\"name\":\"Difference Between Forged and Cast Irons Valve | ZECO Valve\",\"isPartOf\":{\"@id\":\"https:\/\/zecovalve.com\/#website\"},\"breadcrumb\":{\"@id\":\"https:\/\/zecovalve.com\/tag\/difference-between-forged-and-cast#breadcrumb\"},\"inLanguage\":\"es\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\/\/zecovalve.com\/tag\/difference-between-forged-and-cast\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\/\/zecovalve.com\/tag\/difference-between-forged-and-cast#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"item\":{\"@type\":\"WebPage\",\"@id\":\"https:\/\/zecovalve.com\/\",\"url\":\"https:\/\/zecovalve.com\/\",\"name\":\"Home\"}},{\"@type\":\"ListItem\",\"position\":2,\"item\":{\"@type\":\"WebPage\",\"@id\":\"https:\/\/zecovalve.com\/tag\/difference-between-forged-and-cast\",\"url\":\"https:\/\/zecovalve.com\/tag\/difference-between-forged-and-cast\",\"name\":\"Difference Between Forged and Cast\"}}]}]}<\/script>\n<!-- \/ Yoast SEO Premium plugin. -->","_links":{"self":[{"href":"https:\/\/zecovalve.com\/es\/wp-json\/wp\/v2\/tags\/3265","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zecovalve.com\/es\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/zecovalve.com\/es\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/zecovalve.com\/es\/wp-json\/wp\/v2\/posts?tags=3265"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
