Process for producing pozzolanic, synthetic blast furnace slag, belite or alite clinker as well as pig iron alloy from oxidized slag and apparatus for implementing the method

摘要

FIELD OF THE INVENTION The present invention relates to a process for the reduction of oxidized liquid slag on a molten metal to produce not only pig iron alloys but also pozzolanic, synthetic blast furnace slag, bellite or alite clinker from the oxidized slag, maintaining a carbon content between 2.5 and 4.6 wt% To this end, carbon is blown into the melt through a submerged tuyer.
