Silicon carbide brick

Short Description:

Silicon carbide bricks are made of silicon carbide as the main raw material, mixed with various binders according to requirements, and formed by high pressure. Silicon carbide bricks have high thermal conductivity, good wear resistance, thermal shock resistance, and corrosion resistance. They are ideal energy-saving materials for industrial kilns. It can be used for lining of aluminum electrolytic cell, molten aluminum pipe and kiln furniture for ceramic kiln, lower part of large and medium-sized blast furnace shaft, furnace waist and belly, aluminum refining furnace lining, zinc distillation tank lining, etc.

Productive Process

1.Raw material quality control including physical and chemical testing.           
2.Crushing and grinding of bulk raw materials.
3. According to customer data sheet required to mixing Raw Material.
Pressing or shaping the green brick depend on different raw material and brick shape.
4.Dry the bricks at dryer kiln.
5.Put the bricks into the tunnel kiln to burning by higher temp from 1300-1800 deg.
6.The quality control department will inspect the finished refractory bricks random.
