Abstract

The low pressure casting process of the C5M4 end cap was simulated by the ProCAST software.By orthogonal experiments

the effects of pouring temperature

mould preheating temperature

filling pressure and filling speed on the low pressure casting process of C5M4 end cap were analyzed based on the optimized pouring scheme from experiments on different gating systems.Through orthogonal experiment

the optimized technological scheme was presented as pouring temperature of 700℃

mould preheating temperature of 250℃

filling pressure of 40 kPa and filling speed of 80 mm/s.Through adding risers on the basis of the optimized technological parameters

shrinkage porosities of end cap can be reduced obviously from 75.23 cm

to 68.96 cm
