All of us has known that fused cast azs block is produced by casting method, which makes the fused cast azs block form many excellent properties, however, the operation in casting process has great influence on the quality of fused cast azs block, and it not only affects the appearance of fused cast azs block, but also directly affects the inner quality of fused cast azs block. The characteristics in casting operation process are as below:

1. There are intense heat exchange process and chemical reaction process between molten liquid and casting mold while in casting process. As the temperature of molten liquid is high, which forms a big difference in temperature with casting mold, so in casting process, molten liquid is continuous cooling and temperature decreases, however, the casting mold is heated, composition of casting material decomposes and gasifies, and casting mold has some chemical reactions with molten liquid, all of which increase the cavity pressure that is unfavorable to the filling type. When it is serious, there will be a rise, which makes the fused cast azs block have the defects of porosity or insufficient casting.

2. It is an unstable process for molten liquid casting process, such as the imparity of pouring stream and flowing quantity which will form the defects of bulging, cold shutting, and shell nuzzling in casting mouth.

3. Filling sand process of molten liquid is similar to filling a porous container, because mold wall has a certain permeability, if the pressure in the cavity is lower than the air pressure inside the sidewall of mold, the molten liquid will indraw air outside which will form pores, or, molten liquid will be pressed into pore wall of mold which result in serious attached sand.

4. The casting process has a significant effect on the temperature distribution of the casting.
