Zirconia Refractories Bricks Products
1. The product used the fused mullite ,fused zirconia and zirconia sand as the main raw material, high-performance powder as additives, and organic material from the temporary binding agent.
2. After mixing, drying, forming, firing at high temperature shuttle kiln made.
3. Products, dimensions, physical and chemical indicators of useful life are up to customer requirements.
4. The company produced lightweight insulation refractory material by its high purity, mechanical strength, and low thermal conductivity.
Application: The zirconia brick is widely used in carbon black furnace, gasifier, gas furnace, hydrogen furnace, as well as shuttle kilns and other high-temperature furnace equipment.
