Title:
Corrective strategy of the reduction degree in Smelting of a ferroalloy
Document Type and Number:
Japanese Patent JP6148230
Kind Code:
B2
Abstract:
The invention relates to a method for improving the reduction degree of metal components in a chromite concentrate when smelting ferroalloy suitable for manufacturing of stainless steel. The chromite concentrate is fed together with nickel-containing raw material so that by means the amount of nickel-containing raw material it is achieved a desired reduction degree for the metal components of ferroalloy.
