摘　　要：针对铁路货车转K6摇枕铸钢件试制过程中出现的表面夹砂和浇不足等技术问题,设计了一种一体拼接式耐火材料三通浇注系统,解决了浇注过程中高温钢液紊流及冲砂导致的铸件表面夹砂等问题,提高了浇注速度和铸件出品率。在摇枕旁承盒上设计专用排气架,解决了因排气不畅导致的旁承盒浇不足等难题。新工艺提高了铸件质量,节约了返修成本。A one-piece splicing refractory material three-way gating system was designed to address the technical issues of surface sand inclusion and misrun during the trial production process of railway freight car K6 swing bolster cast steel parts,and solved the problems of surface sand inclusion caused by high-temperature steel liquid turbulence and sand washing during the pouring processes,and improved the pouring speed and overall yield of casting.A dedicated exhaust bracket was designed on the side bearing box of the swing bolster to solve the problem of misrun of the side bearing box caused by poor venting.The new process has improved the quality of castings and saved repair costs.
