Melting & Casting Procedure
- Ceramic shell mold are sent to preheated sintering furnace after de-wax process. The temperature needs to reach about 1100 degrees and the purpose is to remove the residual wax and moisture and increase the strength of ceramic shell mold and the floating of liquid iron.
The ceramic shell mold send into a sintering furnace.
- To compound different material ingredients such as stainless steel, carbon steel, alloy steel and special alloy is according to the client’s request and demand.
To heat temperature of high frequency induction furnace till about 1600 degrees and shall be remove slag and gas to maintain liquid iron clean.
- The compound ratio of liquid iron pours into the preheated ceramic shell mold and waits for cooling.
- Remove shell by shell removal machine.
