Technical Key Points
Ø In the premise of ensuring a large cross-sectional area, a reduced and steady flow rate, no spray of molten steel which may caused secondary oxidation, the runner should be as thin as possible to reduce the suction area of the runner. The thickness of the inner runner should be less than 0.7 times of the wall thickness of the casting, and the width of the runner should be more then 4 times of the thickness, which is more favorable for the slagging and cleaning of the molten steel.
Ø Appropriate increase of pouring temperature will help to facilitate the rising escape of gas and reduce the generation of pores. In the box joint surface, place radial venting grooves (dense but not deep, to prevent fire), can also play the role of auxiliary exhaust.
Ø We are an innovation driven company, we have five patents, and will get another 13 patents within a few months.
Ø We are willing to develop all new material only if it’s required in application.
Ø Our advantage lies in component control, especially for ultra low carbon steels, stainless steels and duplex stainless steels.
Ø Crack is the fatal defect of pressure vessel. We guarantee that the pump and valve castings have no crack inside and outside, and have good withstand voltage performance.
