A novel twist investment casting tube sheet

A novel twist tube sheet investment casting, comprising sprue cup, twist tube sheet, said sprue cup arranged below the runner, the runner is provided on both sides below horizontal rotary runner, said rotary pouring channel tube connected through twisted sheet into a plurality of gates; the gate into the horizontal symmetry. The present invention reasonable structure, reducing the probability of occurrence of inclusions in molten steel, and the rotational direction of the rotary runner and distortion in the distorted tube sheet coincides with the rotation direction of the blade, to avoid distortion of the tube sheet products appear twisted blades local shrinkage, distortion extended the life of the tube sheet while the sheet twisted tube RT test pass rate of products increased from the original 20% to 98%, to avoid the waste of labor, saving production costs.
