Features of Silica Ramming Mass
- Good Wear Resistance: The main content of mass is SiO which has a stable physical structure. In the smelting steel process, the metal will shock the lining of high-temperature equipment. Using this ramming mass can greatly sustain a stable volume of industrial equipment.
- Acid Chemical resistance: SiO is a kind of acidic oxide material. So it can resist the acid chemical slag erosion. The linings of induction furnaces use different lining materials according to different chemical slag. Alkaline and neutral linings can resist alkaline slags. Acid and neutral linings can resist acid slag.
- Low Thermal Expansion: Silica ramming mass has a low thermal expansion that can sustain a steady volume of industrial equipment. The thermal shock resistance of the ramming mass is better than the alumina ramming mass. The frequent outages of induction furnaces will not crack as linings.
- Low-cost Linings for Equipment: Ramming mass price is lower than other refractory materials. Besides, it has a stable physical and chemical structure. In this situation, the life cycle of the ramming mass can be extended.
Application of Silica Ramming Mass
Silica ramming mass can be used for the lining of induction furnaces, electric arc furnaces, incinerators, and foundries. This can also used for ladles and tundishes in steel plants and glass furnaces.
