FAQ
1. What are refractory products?
Refractory products refer to functional materials which can resist high temperature or even ultra-high temperature. They are widely used in various high temperature heat treatment equipment, such as steels-melting kiln, glass kiln and cement kiln. The quality of refractory products directly affects the usable life of kilns and the quality of the final industrial output. Refractory products are made from various natural minerals such as silica, dolomite, graphite, zircon, magnesia, high aluminium ore and chrome ore through numerous technical refining processes. They have valuable features such as high-heat insulation, high-heat resistance, high strength, high hardness, good volume stability, oxidation resistance, excellent complexity, wear resistance, corrosion resistance, etc.. Some refractory products even have special features such as high ventilation, heat conduction and extreme hardness.
2. Any differences between shaped and unshaped refractory products?
Shaped refractory products can be pressed into bricks and are, generally used in building heat treatment equipment such as metallurgical kilns. Unshaped refractory products refer to fire-resistant casting materials. They can be moulded into whatever shapes and are suitable for building different high temperature furnaces and using as the lining in different heat treatment furnaces.
