What Is a Steel Casting? Casting Process

A steel casting is the product formed by pouring molten steel into a mold cavity. The liquid steel cools and solidifies in the mold cavity and is then removed for cleaning. Heat treating may be required to meet desired properties. This process provides the near net shape and mechanical proper­ ties required by a purchaser to meet his specifiions.

Lecture 26 Degassing Practice - NPTEL

molten steel from BOF or EAF is placed on top of the vacuum chaer and the gap is vacuum sealed. Alloy additions are made under vacuum. Stream is allowed to fall in the ladle where molten steel is degassed. Alloy additions are made under vacuum. In some plants degassing is done during tapping. In this arrangement molten steel from EAF is tapped

Steelmaking - Wikipedia

Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. Limiting dissolved gases such as nitrogen and oxygen and entrained …

Steel Production - American Iron and Steel Institute

How Steel Is Made Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day.

Introduction - Iron and steelmaking I: Ironmaking and raw

During steel-making process, it increased up to 17 degrees Celsius. Temperature level is also different. And the biggest difference is the operation type. In iron-making process, raw materials are continuously delivered to reaction vessel and products, hot metal, are also tapped continuously. This is really a continuous process.

Steel - Electric-arc steelmaking | Britannica

The major charge material of electric-arc steelmaking is scrap steel, and its availability at low cost and proper quality is essential. The importance of scrap quality becomes apparent when making steels of high ductility, which must have a total maximum content of residuals (i.e., copper, chromium, nickel, molybdenum, and tin) of 0.2 percent. Most of these residuals are present in scrap and, instead of …
