Cryogenic Valve Casting Method |
| abstract |
The present invention relates to a cryogenic valve casting method having a narrow diameter of an end region compared to a central region, comprising: preparing a wax model; Coating a ceramic shell on the wax model; Coating the ceramic shell on the wax model over a predetermined number of times and then injecting a filling gel into the hollow region of the wax model; Adding a ceramic shell to the outside of the wax model in which the filling gel is injected to complete the mold; Melting the wax model and the filling gel in the mold; Injecting molten metal into the mold; Removing the mold. This prevents the filling gel from blocking the inlet of the wax model, thereby minimizing the occurrence of defects. |
