SK33 SK34 Fireclay Brick

Bricks that can withstand high temperatures above I580 C are called refractory bricks. It is a finished product obtained by mixing refractory clay with clinker (calcined and pulverized clay), stirring, pressing and molding, drying and calcining. According to its shape and specifications, it can be pided into two categories: standard type and special-shaped type. Refractory bricks can be pided into ordinary type (refractory degree of 1580 ~ 1770 ℃) and advanced refractory bricks (refractory degree of 1770 ~ 2000 ℃) according to their refractory degree. According to their chemical properties,
