Shelling mould casting process

The cross-sectional area of the boiler safety valve and hose must not be smaller than the cross-sectional area of the inlet of the safety valve. If several safety valves are installed on a short tube directly connected to the furnace, the cross-sectional area of the passage of the reducer tee shall not be less than 1.25 times the exhaust area of all safety valves.

Safety valve should generally be installed exhaust pipe, exhaust pipe should be directly to the safety location, and have sufficient cross-sectional area to ensure smooth exhaust. Safety valve exhaust pipe should be installed at the bottom of the cavity, receiving the safety site of the evacuation pipe can not be installed on the exhaust pipe and evacuation pipe

What is the casting method of laminated sand mold, according to the core shooting machine will be shot into the overall temperature of laminated sand raw materials to 3500?

450 ℃ in the mold casting mold, the laminated sand casting furnace bar prefabricated mold casting end caps glue fixed in the mold casting on both sides of the open, laminated sand casting parts forming core and around the clamping surface into one of the two sides of the open laminated sand mold casting. Clad sand mold casting molding and curing time in the above mold for 30 seconds ~ 50 seconds. The present invention has the advantages of short production cycle, high efficiency, zero pollution, small sewage discharge, environmental protection, etc.
