Abstract：
In order to reduce the heat loss of molten metal during EPC casting,simplified casting system was one of the effective measures.Casting technology of steel casting with carbon emission method,steel liquid was injected from riser,in terms of form,there was no casting system,in fact,the mold cavity was used as the casting system,and the mold cavity was used as the gate.The results show that the best technique of top injection is realized by using the mold cavity as the gate and the gate is directly connected to the top of the riser or the casting.After the gold liquid enters the mold cavity,it falls directly to the mould bottom,and then the liquid level rises,which shows the positive thermal field with low temperature at the bottom and high temperature at the top of the casting.This is a process worthy of research and recommendation.
