This raw material mixture is melted in an electric arc furnace. The molten metal is refined and decarburised in an Argon-Oxygen Decarburiser (AOD) vessel by blowing oxygen, argon and nitrogen into the molten steel. The refined stainless steel is processed through a continuous casting machine to produce stainless steel slabs.

Liquid metal must flow to where crystallization is occurring from some other part of the casting. If there is not enough liquid metal to feed the crystal growth, or the gates freeze off before the casting is completely solidified (preventing additional liquid metal from reaching the casting) shrinkage will occur in the casting. This shrinkage could be internal leaving holes and gaps inside the ...

In the metal casting process, metal shapes are formed by pouring molten metal into a mold cavity, where it is cooled and later extracted from the mold. Metal casting is arguably the earliest and most influential industrial process in history. It's used to make many of the metal objects used in our daily lives: automotive parts, train wheels, lamp posts, school bus pedals, and much more. Plus ...

In metalworking and jewellery making, casting is a process in which a liquid metal is somehow delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a 3-dimensional negative image) of the intended shape.The metal is poured into the mold through a hollow channel called a sprue.The metal and mold are then cooled, and the metal part (the casting) is extracted.

Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots.Since then, "continuous casting" has evolved to achieve improved yield, quality ...

On the surface, cast iron and cast steel castings look very similar. Casting offers exceptional capacity for design detail, often eliminating the need for additional fabrication and assembly. Many materials can be cast, including several types of metals and synthetics, but iron and steel in particular feature excellent mechanical properties for a wide range of applications.
