Corundum and products with other oxides are characterized with excellent thermal shock resistance, resistance to corrosion, erosion and spalling, and hence, they are new type good refractories used for glass furnace, cement kiln, heaters molthn steel ladle, metallurgical furnaces for nonferrous metals and furnaces for chemical engineering industries.
Titanium corundum orifice ring and tatannium ring use form a complete set with spout of feeder of glass furnace, they are characterized with resistances to corrosion and erosion of glass lipuid.
