Steel is one of the most preferred materials for construction, manufacturing of tools, cars and for various other applications. It is an alloy of iron and some other element such as chromium. Steel has been manufactured since ages, but the large scale commercialization of the process began only in the 19th century.
2.1. General Briefing on Intelligent Manufacturing in the Steel Industry of China. Figure 1 illustrates the two primary production models that are typically used in the steel industry: the long process of ironmaking and steelmaking procedure (LPISP) and the short process of steelmaking procedure (SPSP). The burden materials utilized in the LPISP are very different …
The production of steel in an EAF is a batch process. Cycles, or "heats", range from about 1-1/2 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. Scrap steel is charged to begin a cycle, and alloying agents and slag materials are added for refining. Stages
