Gunning mass for blast furnace / Strong adhesion and easy construction
Product description:
The blast furnace press and spray materials produced by Xinyu are made of high-quality high-alumina bauxite, fused corundum, high-grade silicon carbide and other raw materials. They are characterized by high strength, corrosion resistance, strong adhesion and easy construction. After the blast furnace can be used for about one year, it is an important technical measure to improve the life of the blast furnace.
