摘要
一重集团公司在湿型铸造缸盖等球铁件时，采用了可控压力冒口，生产了实验压力在23．5MPa以上不修漏的铸件，显著地很高了合格率。
篢he pressure-controlling risers were adopted to produce ductile iron cylinder head and other castings in green sand moulds. The castings have experienced pressuretightness test under the pressure of above 23. 5 MPa without leakage and the rate of qualified castings was obviously increased.
