Refractory silicon bricks

1. Characteristic of refractory silicon bricks

High strength

Low thermal expansion coefficient

Good thermal conductivity and thermal shock resistance

Good resistance to liquid aluminum erosion capability

High erosion

2. Applications of refractory silicon bricks

Widely used in large aluminum electrolytic cell of lining material. In the electrolytic aluminium industry, because of silicon brick 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.
