High Temperature Flexural Strength Silicon Carbide Refractory Bricks
Silicon carbide brick is adopts silicon carbide as the main raw material, after mixing ,forming, drying, firing at high temperature in shuttle kiln, the whole process is finished.
Features:
1.Good abrasion resistance.
2. High temperature flexural strength.
3.Good thermal shock resistance.
Application:
Silicon carbide brick is widely used in linings of heating furnace.

Manufacturing Process Flow:
First, qualified raw materials enter to our raw materials warehouse
Second, all materials including fine powders, aggregates, binding agent are batched according to the technical agreement.
Third, finished raw materials is shaped by 630 tons pressure machine or 2500 tons automatic hydraulic pressure machine.
Forth, green bricks is dried in the dry kilns between 40℃ and 120 ℃, and then sintering in high temperature according to the firing curve.
Last, check the quality of finished refractory bricks and qualified products are packed as request.
