High strength magnesia ramming mass takes fused magnesia as the raw material, added with kinds of superfine powder additive and binding agent.
The magnesia ramming material is one type of unshaped refractory products, it is mainly use sintered or fused magnesia as the main refractory raw material, then added low temperature binder and high temperature sintering agent. the main application: induction furnace lining, tundish lining, electric furnace bottom lining, the tundish magnesium ramming material is used in the working layer of tundish, and the service life can be reached about 35 hours after casting, which is generally applied to large tundish.
Applications:
It is mainly used in steelmaking open hearth furnace, converter lining and tap hole filling material etc.
Tundish magnesia ramming material features:
1. High temperature resistance and high RUL temperature.
2. Steel scouring resistance, erosion resistance.
3. Good thermal shock performance.
4. High temperature volume stability.
