REFRACTORY COMPOSITIONS OF PLUG FOR TAP HOLE OF CONVERTER USING BY WASTE REFRACTORY

摘要

The present invention relates to a raw material containing slag obtained by pulverizing and selectively extracting an acid-neutral system waste refractory, waste containing the impregnated layer and alumina powder, A binder for binding the waste and the alumina powder; Wherein the waste is 70 to 80 wt.% And the alumina powder is 20 to 30 wt.%, And the content of the binder is 3 to 3 parts by weight of the main raw material. To 5 parts by weight of a refractory composition for a converter for recycling waste refractory, In the acid-neutral refuse generated from the steelworks, the aggregate is selected for use as a raw material of the refractory, and the plug of the transformer is manufactured by using the aggregate formed by crushing the remaining slag or the refractory material that has now been impregnated, It is possible to reduce the cost of disposing or disposing the waste, and at the same time, it has an effect of enhancing the utilization of resources.
