Fired slide gate plate
High temperature fired slide gate plates developed by Zhengzhou CH refractories 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. The products have low impurity and are stable on quality. Good performance on strength, erosion resistance and thermal shock resistance enables the slide gates to cast multiple ladles of molten steel.
Zhengzhou CH refractories can produce and provide Al2O3-C or Al2O3-ZrO2-C material according to customers’ special needs.

Un-Fired slide gate plate
The un-fired slide gate plate series products are made of corundum, mullite, and high-quality calcined bauxite. They 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. Un-fired slide gate plate has high temperature strength, strong oxidation resistance, good thermal shock resistance, small sliding surface wear and small injection hole expansion diameter, which can fully meet the requirements of the casting process and have a good use effect.
