1,Product description:
The main raw materials of the product are high quality fused magnesia, fused corundum sand and sintered mullite sand. The product forms corundum phase, spinel phase and mullite phase solid solution in the process of use. It has compact structure, good spalling resistance, excellent impact resistance and erosion resistance.
The raw material has high purity, no pollution to molten steel, good mechanical properties at high temperature and good volume stability at high temperature. Especially during the operation of the ladle, the product has excellent anti stripping performance, which depends on the effect of corundum phase and spinel phase solid solution formed at high temperature. The application effect of the product is better than that of other refractory castables.

3,Salient features of Castable for Wall of Ladle:
1) Castable for Wall of Ladle has good corrosion resistance.
2) Castable for Wall of Ladle has good slag resistance.
3) The high temperature volume stability of the product is good.
4) The product has good slag penetration resistance.
4,Applications of Castable for Wall of Ladle:
1) Large ladle
2) Medium-sized ladle
3) Tundish for Continuous Casting
5,Product knowledge:
1) The fine spinel powder in the product can absorb a large amount of iron oxide in the slag, solidify the iron oxide and slow down the soaking of the slag.
2) CaO in slag and Al2O3 in fine powder of product form needle-like substance, which makes pore fine and inhibits slag penetration.
3) The liquid phase of SIO2 becomes viscous and inhibits slag penetration.
6.Good feedback of product use effect,the products have been exported to Australia, Oman,Kenya.
7.We are a professional supplier, who can provide customers with free product technology, use and other issues.
