Stable Capability, High Quality, Excellent Service, Competitive price is the most important advantage of our products

Widely used in large aluminum electrolytic cell of lining material. In the electrolytic aluminium industry, because of nitride bonded silicon carbide products can be made thin wall lining, enlarge the tank capacity, improve the thermal conductivity, can rapid cooling, and they are permitted to enter a higher power, increase the tank production capacity, at the same time, in its surface can form alumina and cryolite of eutectic content, in order to protect the tank lining work layer, prolong service life, therefore, this product is aluminum industry generally welcome.
