Technical Parameters
Product description

 

Silica fire brick has the following performance characteristics:

1. High temperature resistance: the high temperature performance of silica fire brick is very excellent, usually can withstand high temperatures above 1500 ° C, has good seismic performance, can effectively slow down the furnace cracking shock absorption.

2. Corrosion resistance: silica fire brick has a certain acid and alkali corrosion resistance, can withstand a variety of chemical substances erosion and corrosion.

3. High strength: silica fire brick has a high strength and can withstand great pressure and load.

4. Good thermal conductivity: silica brick has good thermal conductivity, which can reduce the surface temperature of the furnace body and make the internal temperature of the furnace body evenly distributed.
