Tundish Impact Plate Precast Refractory Shape Erosion Resistant For Steel Making Plant
The tundish impact plate is made of high-quality magnesia as the main raw material, microsilicon as bonding agent, and the suitable high-temperature reinforcing agent is added to develop the magnesium castable with excellent performance. The magnesia impact plate made by the same has good application effect.
Reasonable use of the impact plate can avoid the high temperature molten steel directly impacting the bottom of the tundish, effectively extending the service life of the lining material of tundish.
Tundish impact plate features:
1. Magnesium impact plate is easy to install, baking without cracking
2. Resist the erosion of molten steel and slag, no pollution of molten steel
3. It can meet the requirements of steel mills: improve the comprehensive life of the tundish refractory materials, reduce consumption and increase the continuous casting rate.
