Abstract：The application of gas heat treatment equipment in aluminum-silicon alloy castings for catenary was analyzed,and explores a production control method of heat treatment process for large gas heat treatment production line through process verification and special process confirmation.The gas heat treatment process of aluminum-silicon alloy casting for catenary was studied by orthogonal test.The results show that the optimal heat treatment parameters are 535℃×11 h+165℃×5 h.Under these conditions,the Al-Si alloy castings show good mechanical properties.
