The molten slag belonged to the CaO-SiO2-CaF2-Na2O-Al2O3-MgO slag system is tested in the centrifugal casting with the remelted steel water, the domestic composition of the used slag is decided from the given method.

The production technique and main parameters of bimetal composite pipe—compounding high chromium cast iron in inner wall of steel pipe,by long launder centrifugal casting are presented.

Study of Polyurethane Resin with Heat Resistance for Vacuum Casting Manufacture;

Two types of two components polyurethane resins(PU) for vacuum casting were synthesized by one-step method and quasi-prepolymer method respectively.

A water modeling experiment on vacuum casting from tundish was carried out.

Using the vacuum pouring process,the vacuum pouring equipment was developed.

For the molten steel with lower carbon and oxygen activity,the vacuum pouring process with tundish plug rod blowing argon has been developed in order to decrease the hydrogen content in steel more effectively.
