Abstract

The invention relates to metallurgy and concerns a device for bottom blowing of metal which can be used for out-of-furnace processing of steel by nitrogen foul by oxygen. A device has a form of truncated cone and comprises the outside gas-not-permeability and inside gas-permeability refractory layers. The inside layer is made plate-type from refractory and carbonaceous materials, at that the ratio of thickness of refractory and carbonaceous materials is 1:(0.2-0.3). Technical result: enrichment of small transformation of oxidizing component of blowing gas containing of 0.5-3.8 % of oxygen in non-oxidizing one.
