| Abstract: | SCT110T(F-1449P(G))bolster is one of key load-bearing parts for North America railroad freight train.It endures the action of alternating loads with pull,press,and impact bending in operation.In this work,the casting process of the bolster parts was designed based on its structural characteristics and technical requirements.The technological processes,including the side pouring and two-way split unpressurized gating system,setting up exothermic risers on the hot spots of the casting to compensate shrinkage,and LF refining by argon blowing and wire feeding,were adopted to manufacture the bolster castings,and acceptable casting products were successfully obtained through trial production. |
