Production of Ferrochrome and Stainless Steel Eetu-Pekka Heikkinen and Timo Fabritius University of Oulu, Finland 1. Introduction In stainless steel production - as in almost any ki nd of industrial activity - it is important to know what kind of influence different factors such as process variables and conditions have on the process outcome.
The presence of different impurities in bauxite also helps in the Using approximately 50 ferrochrome slag as an aggregate in con- densification process and the formation of mullite. Mullite phase ventional castables saved around the 40 production cost per ton. increases with a simultaneous reduction in the amounts of alumina and silica owing ...
IGH carbon ferrochrome HCFeCr is produced by carbothermic reduction of chrome ore. Electric power is generally used to supply the energy required to carry out the heating, melting and reduction reactions. The production process is energy intensive, and consumes approximately 3,300-3,800 kWh per ton of metal produced. The cost of
Jan 19, 2018 A solid reduction process is described whereby chromite is reduced with the help of calcium chloride to produce ferrochrome alloy powders with high metal recovery.
