Product Introduction
Magnesia ramming mass is a bulk material made of fused magnesia, mixed with a variety of superfine powder additives, and fused cement or composite resin as a binder. The ramming material has good chemical stability, erosion resistance, abrasion resistance, peeling resistance, and heat shock resistance. It is widely used in metallurgy, building materials, non-ferrous metal smelting, chemical, machinery and other manufacturing industries.
Features
1.Good chemical stability.
2.Good erosion resistance.
3.Good abrasion resistance.
4.Good peeling resistance.
5.Good heat shock resistance.
Application
The products are mainly used for the ramming and filling of steel-making electric furnaces, the bottom of ferroalloy electric furnaces, the bottom of steel metallurgical furnaces, the furnace mouth and the tapping mouth, and the ramming and filling of RH furnace bottom.
