6 Steps of Modern Steelmaking Process | 3MVET
Modern methods, however, are still based the same premise as the Bessemer Process, namely, how to most efficiently use oxygen to lower the carbon content in iron. Modern steelmaking can be broken down into six steps: 1. Ironmaking: In the first step, the raw inputs iron ore, coke, and lime are melted in a blast furnace. The resulting molten iron - also referred to as ''hot metal'' - still

Steel - Vacuum treatment | Britannica
21.08.2020· Steel - Steel - Vacuum treatment: Exposing steel to vacuum conditions has a profound effect on all metallurgical reactions involving gases. First, it lowers the level of gases dissolved in liquid steel. Hydrogen, for example, is readily removed in a vacuum to less than two parts per million. Nitrogen is not as mobile in liquid steel as hydrogen, so that only 15 to 30 percent is typically
