  Steelmaking Process - an overview | ScienceDirect Topics

  1 Introduction. During the steelmaking process, various slags are produced as by-products (Shen and Forssberg, 2003 ). The first stage of steel production is blast furnace steelmaking, in which raw iron ore is converted into pig iron, which contains various amounts of carbon, silicon, manganese, sulfur and phosphorus.

  Biochars in iron and steel industries - ScienceDirect

  201911 · In this chapter, we focus our attention on the partial or complete replacement of coals and cokes with biomass chars in iron and steelmaking processes. The utilization of biochars in ironmaking is expected to lower carbon and energy consumption and reduce operating costs as well as greenhouse gas (GHG) emissions.
