摘要
研究了1.2311塑模钢扁钢尺寸、终轧温度、回火温度等主要工艺参数对其轧后硬度、回火硬度及组织均匀性的影响。研究表明,将其终轧温度控制在850～920℃、风冷后硬度为HRC42～52时可满足淬硬性要求;回火温度为620℃时可满足以预硬化状态交货的技术要求。
The influence of processing parameters, such as finishing rolling and temper temperatures, on the hard- ness and microstructure of 1.2311 plastic die fiat steel were studied. The results show that the delivery technique requirments can be met when the finishing rolling temperature is controlled at 850-920℃ , the hardness of wind-cooling controlled at HRCA2-52 and temper temperature controlled at 620℃ .
