Abstract:
     This invention relates to a process for enriching manganese slags in blast furnace. In this process the existing processing conditions for enriching manganese slags in blast furnace is retained, but a special blowing device is provided to blow oxygen-containing gas onto the slag surface in the furnace hearth. By this process, comprehensive results in high output, lower coke ratio, high rate of manganese content in slag etc. can be obtained.
