Technical Key Points

Ø Ni, Mo, Cu, ferrochromium, ferromanganese, ferrosilicon and other metal alloy materials used in the smelting must be baked at high temperature before adding, so that to thoroughly remove oil and moisture and prevent the oxidation of molten steel.

Ø Structural characteristics of the valve body castings make it easy to generate shrinkage and slag (sand) defects at the bottom, which seriously affect the pressure resistance of the castings, and may cause leakage of the media matter(water, gas, oil, etc.) during application.when setting feeding riser, feeding gate must be set or extended, if necessary, extend the feeding runner to the bottom of the casting.
