| Abstract: | Taking F3000 crankcase produced with green sand mold as example,the reason causing sand collapse defect was analyzed,and corresponding solving measure was proposed to equilibrate the venting by improving venting holes distribution and enlarge the total venting area.As the result,the sand collapse defect of the crankcase casting was reduced on a large scale,and at the same time,no other defects were caused.This result found a new approach for the elimination of the sand collapse defect. |
