The main components of refractory material
The firing process is mainly due to the process of crystallization of mullite (3Al2O3 · 2SiO2). The SiO2 and Al2O3 in the refractory brick form a eutectic and low melting point silicate with the impurity during the firing process, surrounded by mullite crystals. The maximum temperature in the firing process is usually controlled at 1350 ° C to 1380 ° C, and the firing temperature of the low porosity fire clay brick (1420 ° C) is increased. The shrinkage of refractory brick is slightly increased, so that the density of fire clay brick increases slightly and the low porosity is decline.
Refractory brick do not use the same kind of mud to use different appliances, fire mud selection of cleaning water, accurate weighing modulation, uniform mixing, tune the mud can not be arbitrarily diluted with water, mortar fullness is greater than 95% or more, ensure solid brick joints, the surface brick seam jointing with virgin pulp, the shell can not correct the parts with mud.

Refractory brick has a certain shape and scale of refractory material, large unit volume weight, large density, indicating that the density is good, the strength may be high, also known as high temperature load deformation temperature, called the burner change or called the residual line change, refers to each time the equal temperature change in the volume swell shrink, high temperature resistance.
