High alumina refractory brick is made of bauxite or other raw materials with high alumina content by molding and calcining. One of the important working properties is the structural strength at high temperature. With the increase of temperature, it increases, but there is an important performance, that is, thermal shock resistance.
The thermal shock resistance of high alumina refractory brick refers to the ability of refractory brick to resist the rapid change of temperature without damage. In the working environment of coal water slurry gasifier, the service life of high alumina refractory brick is essentially due to the change of high temperature or significant change of the viscosity temperature characteristics of coal ash. Generally speaking, the higher the temperature is, the lower the viscosity is and the better the fluidity is. The more serious the erosion and penetration of the high alumina refractory brick is, the greater the erosion rate is and the shorter the service life of the brick is. So the temperature control is very important.
If our actual situation is often plagued by such problems, then today, we can solve them according to these principles. It is these aspects that make the high alumina refractory brick more suitable for our actual use.
