Technical Key Points

Ø Pouring speed: in the case of ensuring smooth gas discharge from the cavity, higher pouring speed can be used;pouring operation requirements: after casting, as soon as the castings solidified, remove the pressure iron and box, to reduce the casting shrinkage resistance and avoid cracks and flaws.

Ø For the pressure resistant castings of valve body, to prevent shrinkage and slag defects are the key points that always need to pay great attention when design casting process, all aspects need to be considered to reach a comprehensive balance, among all the measures, to increase the riser height is a very effective one.
