Production Introduction |
This product uses high-quality magnesia and basic composite refractory raw materials and is obtained combined with special composite binder and additive agent. It has the advantage of higher corrosion resistance and resistance to thermal shocks, which can effectively extend the service life of the tundish and is easy for removal. This product can adopt either mechanical spraying construction on site, or manual coating operation. |
