Patent application

P-411272

The subject of the invention is a method of production of low-carbon ferrosilicochrome in electric arc-resistance furnaces. Ferrosilicochrome is used as a reducing agent in low-carbon ferrochrome production processes as well as an alloy and deoxidation additive for production of chromium steels.

 

The object of invention is to reduce carbon content in ferrosilicochrome and to conduct a two-phase process of obtaining low-carbon ferrosilicochrome in electric arc furnaces and a refining ladle without additional costs of charge materials and with the use of bath heat in the refining ladle.

 

The solution allows to:

  • produce the novelty pure alloy with reduced carbon content to 0.01% – the better quality of alloy (lower content of carbon and undesired gasses), the higher its price. Premium for high quality of alloy reaches even 20%.
  • reduction of unit energy consumption per metric ton of final product by 10%,
  • reduce alloy losses during secondary metallurgy process,
  • reduce  costs of refining  process thanks to utilization of silica dust, byproduct from silicon alloys production as refining agent.
