More Information
Summary:The invention discloses a nickel matte bottom-blowing refining process and a nickel matte bottom-blowing refining furnace. The nickel matte bottom-blowing refining process comprises the steps of adding low-nickel matte and flux into the nickel matte bottom-blowing refining furnace; continuously blowing oxygen-containing gas into melt in the nickel matte bottom-blowing refining furnace from the bottom of the nickel matte bottom-blowing refining furnace by using a bottom-blowing blowgun; respectively discharging high-nickel matte and blowing refining slag from the nickel matte bottom-blowing refining furnace. According to the nickel matte bottom-blowing refining process and the nickel matte bottom-blowing refining furnace, disclosed by the invention, the continuous blowing refining of the nickel matte can be realized, generated flue gas is continuous, little and stable, the concentration of SO2 is stable, the environmental friendliness is good, the efficiency is high, and the production costs of high-nickel mat
