Abstract
The invention relates to a casting process for valve production, which is characterized by comprising the following steps of: preparing a blank; the clean blank is put into a smelting furnace, the blank is heated till the blank is in a molten state, the heating time ranges from 20 min to 50 min, the heating temperature ranges from 1200 DEG C to 1450 DEG C, meanwhile, a casting mold is heated, an electric heating wire is arranged in the casting mold, the casting mold is heated through the electric heating wire, the heating temperature ranges from 100 DEG C to 200 DEG C, and the mold is in a preheated state; a release agent is added into the mold, then the heating temperature of the mold is increased, and then the molten metal solution in the second step is poured into a casting mold; the pressure of the casting mold is tested through a casting press for 4-6 min, then the mold is cooled, finally demolding is conducted, and a valve casting part is obtained; and the valve casting obtained in the fourth step is subjected to shot blasting and polishing treatment.
