Silicon refractory brick is one type of the refractory prodution, consisted of tridymite/cristobalite and little amount of quarts and glass phase.It is manufactured with the material of nature silicon rock.Its SiO2 content is above 94%. And meanwhile it has high bulk density,high refractoriness tempreture,good corrossion resistant property,good slag resistant property,high refractoriness underload and good stability in the super high tempreture.
Our silicon refractory brick has been used in many blast furnance air heater, in many famous steel mill factories and many other steel factories .The silicon brick is always used to bulid the walls around the air heater above the regenerative chamber and the top hat of the air heater sotven.Cause this part of air heater bears highest tempreture of the hot wind.So this part of the air heater requires the best refractoriness and stability for the structure.
