Castables for ladle working layer is made from high purity corundum, magnesium aluminate spinel and fused MgO as main aggregates, superfine powder bonding technology and appropriate additives.
Main raw materials of Ladle Working layer gunning mix are corundum and magnesium aluminate spinel, after spraying use on the working layer surface in carbon-free ladle.
Al2O3-SiC Castable for Metal Mixer is developed with high quality bauxite, corundum and SiC as the main raw materials, and bonded by low cement or ultra-low cement.
High temperature fired slide gate plates developed by Zhengzhou Caihua are produced via high speed mixing, high pressure pressing, high temperature firing, vacuum and pressurized pitch impregnation, precise surface grinding and hot stainless steel looping processes. Fired slide gate plates have low impurity and are stable on quality.
Monolithic castables for ladle safety lining are composed of corundum, high quality bauxite, superfine powder and other ingredients and featured with good work ability on site casting, high strength, high volume stability and long life span.
Various kinds of fire proof mortars are available at Zhengzhou CH Refractories, which include corundum based, corundum Cr2O3 based, high alumina based and Al203-MgO based.
