摘　　要：用热模拟试验研究了钢绞线用钢连铸坯的高温塑性曲线,确定连铸拉矫温度应控制在1 020℃,建立了连铸二冷配水模型。通过PROCAST软件模拟钢绞线用钢凝固过程的冷却曲线,并对模型参数进行了优化。射钉试验和生产实践证明:采用优化的二冷配水技术可有效改善铸坯质量,降低铸坯的裂纹缺陷。The high - temperature plastic curve of continuous casting billet for steel strand is studied in thermal modeling test, determined the continuous casting stretcher- straightening temperature be controlled at 1 020 ℃, the continuous casting secondary cooling water proportioning model built. The cooling curve of solidification process of steel for steel strand is simulated with PROCAST software, and the model parameters are optimized. It is proved from pin penetration test and production that the optimized secondary cooling water proportioning technique can effectively improve the billet quality, reduce cracks.
