TIANAO REFRACTORY TECHNOLOGY

Ramming mix for bottom of EAF

It takes high purity caustic calcined dolomite and high purity caustic calcined magnesia as main raw material , adding adequate amount sintered agent, fine ground, balling under high pressure , burned in high temperature rotary kiln, then crushing, screening, proportion, mixing. it is characterized by high dense , high strength, high corrosion resistance, high thermal resistance, and volume stability, is widely used for the bottom of ultra-high-power, high-power, normal-power EAF and DC EAF and ferroalloy furnace.
