Abstract：By using a new type of evaporative material EMB,the problem of carburization of steel castings and back-spurt of liquid steel(due to gasses generated too much and too fast from the foam pattern)were solved.For many years,steel castings cannot be directly poured with EPC,this problem was solved with this method.High quality low-carbon steel castings are obtained,and casting yield is improved.The stability and consistency of steel casting production by EPC is greatly improved.
