3O
4Reduce the vulcanization reaction of slag making reaction and copper.The reductive agent that in electric furnace, no matter adopts is solid-state, liquid state or gaseous state, and the reductive dynamic conditions is all bad, so Fe
3O
4Reduction ratio low, the furnace bottom frozen crust is thicker, worsens the working of a furnace; It is the blowing pulp water to be quenched prepare burden with copper ore concentrates, flux for the small-particle material that the melting dosing method is returned in shrend; Put into smelting furnace and reach the purpose that reclaims copper; The equipment that this method increases is few; Process is simple; Main drawback is to cause the fuel rate increasing degree of melting operation big, and the blowing slag of allocating into is difficult to fusing in regular furnace run, and smelting slag character worsens; And the formation mechanical entrainment, cause the waste cupric of smelting slag too high and subsequent disposal is difficult.
Summary of the invention
The objective of the invention is to change the defective of existing blowing slag dilution treatment technology, provide to propose a kind of the P-S transform converter to be become to have reduction dilution method and (converter) equipment that temperature adjustment function, solid reductant spray into the molten bath function.
