Refractories>1790℃;Bulk density>2.8 g/cm3; Normal temperature compressive strength>90 Mpa; Flexural strength>9 Mpa; Reburning line rate0.2%; Thermal shock stability>40次; Max working temperature1350℃Were resistance<8cc | 4 years above | It can be plastic with corundum. This part needs to have three physical properties: fire resistance, wear resistance and thermal shock stability. Because of the inconvenient construction of the parts, it is made of wear-resistant plastic. This material is composed of three reasons; (1) the alumina aggregate plays a role in fire resistance; (2) Al2O3 powder, which plays a role of thermal shock stabilization; (3) Corundum material, which plays a role in wear resistance. | |
