Research of Aluminosilicate Refractorial Erosion Process on the HCL in Blast Furnace Gas

According to the study on blast furnace refractory erosion caused by HCl gas, it was found that HCl gas can promote for the silicate glass phase and the recessive aluminum silicate to transform into mullite and christobalite in the alumina brick, so that it can increase the porosity in the alumina brick. Hcl gas reacts with non-carbon elements to form the chloride which causes the brick to be loose and porous in the carbon brick. Thus the brick loss is accelerated.
