Corundum castable is a refractory material made of refractory products with Al2O3 content more than 90% and corundum as the main crystalline phase with appropriate amount of additives.
Corundum castable is made of refractory products with Al2O3 content more than 90% and corundum as the main crystalline phase, and mixed with appropriate amount of dispersant, coagulant promoter, stainless steel fiber, compounded according to strict formula. Corundum refractory castables have good high temperature strength, wear-resistant and anti-washout, high thermal conductivity, thermal shock resistance, corrosion resistance, good sealing, quick coagulation and so on.
Corundum castable is a refractory castable prepared with corundum as aggregate and powder plus some binding agent. Corundum castables have higher mechanical strength and anti-abrasive properties than high aluminum refractory castables and mullite refractory castables, but the thermal shock resistance is a little worse. It is mainly used as lining materials for boilers, blast furnaces, heating furnaces, ceramic kilns and other kilns.
Under high temperature, corundum castables have high compressive strength and strong stability.
High resistance to slag erosion and penetration of the overall lining, which can resist the scouring of high temperature gases and solid particles.
In the industrial production process, corundum castables can effectively prevent particles, dust and high temperature gases from eroding and affecting the equipment.
In the process of long-term use, corundum refractory castables have low abrasion rate, which can maintain the long-term stable operation of the equipment.
In some specific industrial environments, corundum castables can effectively resist the influence of reducing gases and ensure the normal operation of equipment.
Corundum refractory castables can also be used to make composite materials with mullite and silicon carbide materials, which have high electric insulating properties. Corundum castables have a wide range of applications, in general, in the furnace lining of more than 1500 ℃ above the temperature of the use of good results, the use of a long cycle. But below 1400 ℃ temperature use, the effect is not good, but also easy to flake.
Corundum refractory castables are widely used in many fields, such as building materials, chemical industry, waste incineration power generation, solid waste treatment and other industries. It is an important refractory material that can resist slag erosion, abrasion and gas flushing at high temperatures.
In industrial kilns, corundum castables are mainly used as lining materials for various kilns such as boilers, blast furnaces hot blast furnaces, heating furnaces, ceramic kilns and so on. It can protect the equipment from the damage of high temperature slag and gas. At the same time, the high temperature resistance and stability of corundum castables can also ensure the long-term stable operation of the equipment.
In addition, corundum castables can also be used in the fields of waste incineration power generation and solid waste treatment, which can resist the erosion of high-temperature flue gas and corrosive substances and protect the safe operation of equipment.
