| Abstract: | The design precedure and calculation method for the riser and and gating system of white cast iron castings used in slurry pump were described. Based on the expression proposed by R.C. Creese for calculating the volume of the riser, and taking the riser design for white cast iron castings used in slurry pump as the examples, the procedure for solving dimensions of riser was demonstrated. Some useful measures to intensify feeding effect of riser were introduced, which include adopting insulated feeder; gating system through riser and using one riser to feed several castings. According to these measures, the casting produced has good soundness. |
