Ceramic mold casting refers to the casting method of producing castings using ceramic slurry as casting molds.
The ceramic slurry is mixed of hydrolyzed ethyl silicate and fine refractory sand with relatively pure texture and high thermal stability, such as fused silica, zircon, corundum, etc. Calcium hydroxide or magnesium oxide is often added as a catalyst to make the ceramic slurry gelatinize in a short time. Due to the composition and appearance of the used refractory material similar with ceramics, it is called a ceramic type. Ceramic mold casting is a new process developed on the basis of ordinary sand mold casting.
There are two types of ceramic mold casting:
1.Ceramic molds are all made by pouring ceramic slurry.
2.Using a liner, the ceramic slurry is poured into the gap between the liner and the mold to manufacture the mold.
The most widely used in production is the CO2 sodium silicate sand bottom sleeve ceramic mold. CO2 water glass sleeve has the advantages of high strength, good breathability, and easy production.
