Non-water pressure feed for blast furnace

product Overview:   Non-water pressure feed for blast furnace is a special pressure feed made of high-quality high-alumina bauxite clinker, corundum, silicon carbide and other refractory materials, using phenolic resin as a binder or Press into the mud. It is mainly used for filling between the blast furnace cooling wall and the furnace shell (brand: YRL-LB, CG-01) and between the bottom of the furnace bottom sealing plate and the carbonaceous ramming material (brand: YRL-LD).
