Base on high quality magnesite and graphite as main raw materials, low carbon MgO-C bricks are produced via pressing and low temperature pre-baking and mainly used in slag zone of ladle lined with low carbon or carbon-free refractories for low and ultra-low steel production.
Fast Drying Castable for Iron Notch is made of corundum, high quality bauxite and silicon carbide incorporated with appropriate drying agent. By firing 2 to 3 hours, the products can be put into use, and show excellent performance.
The Unburned slide gate plates series products are made of corundum, mullite, and high-quality clinker clinker. Unburned slide gate plates are made by adding flake graphite, silicon carbide, and silicon metal powder, which are made by high-pressure molding, low-temperature heat treatment and grinding.
