DESCRIPTION
Slide gate plates are composed of corundum, mullite, super-grade bauxite, graphite, Sic and Si as main materials and produced via high speed mixing,high pressure pressing, thermal treatment under low temperature and surface grinding and stainless steel looping. This series of products are characterized with high strength under high temperature,better anti-oxidation and excellent thermal, The sliding surface has little wear and the hole diameter is small, which can fully meet the requirements of the casting process.
