Castables for Iron Runner use dense corundum, brown corundum, high-quality rock, and high-quality SiC as the main raw materials. Castables for Iron Runner is made of low-cement and ultra-low-cement castable technology.
Castables for Iron Runner use dense corundum, brown corundum, high-quality rock, and high-quality SiC as the main raw materials. Castables for Iron Runner is made of low-cement and ultra-low-cement castable technology. Castables for Iron Runner have the characteristics of good heat resistance, strong erosion and erosion resistance. Castables for Iron Runner can be widely used in the iron ditch of thousands of large and medium-sized blast furnaces, which can be cast on site or prefabricated. The iron flux is high at one time and the use effect is good.

In the high temperature state, the anti-crust refractory castable forms a glaze layer on the surface of the material, preventing the penetration of the glass phase in the cement raw material, thereby playing an anti-skinning effect.
Al2O3-SiC Castable for Iron Ladle is developed with high quality bauxite, corundum and SiC as the main raw materials, and bonded by sol.
Siliceous refractory repair material has high load-softening point, low temperature creep rate, high strength, low porosity, strong thermal shock resistance, anti-slag and anti-erosion, and will not damage the repaired structure due to expansionof quartz.
