发明名称 METHOD FOR IMPROVING THE REDUCTION DEGREE IN THE SMELTING OF FERROALLOY
摘要 <p>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.</p>
