摘　　要：为了解决模铸、多火次锻造/轧制的长流程生产M2高速钢线材存在的问题,如生产效率低、成材率低、成本高、能耗高、质量稳定差等,团队克服了M2高速钢可浇性差、裂纹敏感性强、钢坯塑性差、碳化物尺寸控制难度大等难点,采用弧形连铸机生产150 mm×150 mm连铸坯,并在高合金线材轧机上一火轧制线材的短流程,成品ø11 mm线材各项质量指标符合国家标准,碳化物不均匀度和碳化物颗粒度均优于模铸产品。在工业生产中,M2高速钢线材短流程的成功实践,对该产品的工艺流程优化有重要意义。In order to solve the problems of M2 high speed steel wire produced by the traditional long process including ingot casting and multi-heating forging or rolling,such as low efficiency,low productivity,high cost,high energy consumption,low quality stability,etc.The difficulties of poor pouring ability,strong crack sensitivity,poor plasticity of steel billet and controlling carbide size had been overcame.The curved continuous casting billets with 150 mm×150 mm were produced via commercial curved continuous casting machine and followed by continuous wire rod rolling mill.The wire rods withø11 mm show finer carbide size and more homogeneous carbide distribution then that of traditional long process.In the industrial production,the successful practice of the short process of M2 high speed steel wire is of great significance to the optimization of the process flow.
