The refractory temperature of the refractory brick is very high, so its hardness is relatively large. Under the condition of no load, it can be lower than the high temperature without softening and melting. It is a professional industrial brick, especially in the kiln used for smelting, it is inseparable from it. Its wide application is inseparable from its characteristics:
1. Use performance. The refractoriness, load softening temperature, reburning line change, thermal shock resistance, slag resistance, acid resistance, alkali resistance, hydration resistance, CO corrosion resistance, electrical conductivity, oxidation resistance, etc. of refractory bricks.
2. mechanical properties. Compressive strength, tensile strength, flexural strength, torsion strength, shear strength, impact strength, abrasion resistance, creep resistance, bonding strength, elastic modulus, etc.
3. Thermal performance. The thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, temperature conductivity, thermal emissivity, etc. of refractory bricks.
4. Structural performance. Porosity, volume density, water absorption, air permeability, pore size distribution, etc.
5. Physical properties. Structural performance, thermal performance, mechanical performance, use performance and operational performance.
The five characteristics of refractory bricks have been well reflected in its application. It has strict production technology and strong fire resistance. Its characteristics make it more convenient to use.
