Copper matte blow refining process and a bottom matte blow furnace bottom

The invention discloses a copper matte bottom blowing converting process and a copper matte bottom blowing converting furnace. The copper matte bottom blowing converting process comprises the following steps: adding copper matte and a non-alkaline flux into the copper matte bottom blowing converting furnace, blowing oxygen-containing gas continuously into melt in the copper matte bottom blowing converting furnace from the bottom of the copper matte bottom blowing converting furnace with a bottom blowing spraying gun, and discharging blister copper and converting residues from the copper matte bottom blowing converting furnace. According to the copper matte bottom blowing converting process and the copper matte bottom blowing converting furnace, continuous converting of the copper matte can be realized, less fume is produced, the concentration of SO2 is stable, the environment is well protected, the efficiency is high, and the blister copper and sulfuric acid are low in production cost.
