high temperature refractory bricks

high temperature refractory bricks
Product Detailed
High aluminum refractory brick belongs to gender refractory materials with its thermal stability.

Feature:

1.bricks are made from high quality bauxite 2.dry pressed 3.burned under tunnel kiln 4.accurate dimension 5.high strength

Product specification: standard form, normal standard, shaped and special shaped bricks.Can be used in various kilns because of its cheapness and general tray package. Among all of the refractory materials, it is the mostly used in the key positions.Molding method: it has down draft kiln and tunnel kiln and the general sintering temperature is 1360-1480 degrees. It is a kind of aluminosilicate refractory product which aluminum oxide (Al2O3) content is higher than 48%.
