Alumina Insulating Re-Fractory Brick

Alumina insulating refractory brick has the characteristics of strong resistance to acid and alkali atmosphere, strong resistance to reduction, and good thermal shock resistance. It can be used for a long time below 1700℃. In the early 1960s, China began to produce Al2O3 products with a content of 90% to 92% by the foam method. Since the 1980s, more refractory factories have produced products with an Al2O3 content greater than 90% by the burn-out addition method. With the development of science and technology, more production technologies are also constantly improving to better serve customers and customize according to customer needs. Refractory materials have also appeared in various forms, suitable for a variety of occasions, serving people's lives.
