Silicon Fire Bricks for sale
The producing peocess of Silicon Fire Bricks for sale
1) Silicon carbide refractory brick is made of sic raw material, mixed with SiO2 and C.
2) With all the material contact fully, the brick will be pressed under friction press, vibration molding, casting according to its shape.
3) After the billet making, it should be dried under room temperature for 2-3 days.
4)Then it will be sinstered in the high temperature furnace, pass through temperature rise period, temperature constant and temperature cooling period.
5) After sinstered, high quality bricks will be selected.
6) Seaworthy packing and timely delivery are supplied.
With different binding agents, they are devided into several types-for.
Tech Data and their applications are as follows:
1) Clay bonded silicon carbide refractory brick,
It has good oxide resistance, high thermal conductivity. Widely used in high temperature industry as refractory muffle board in industry kiln furnace, plate, sagger etc.
