【摘要】 介绍了一套中厚板正火控制冷却系统,详细说明了控制冷却系统的机械设备及自动控制系统的组成及特点。通过对某厂生产的几种正火钢板性能数据的比较得出以下结论:钢板正火后经控冷系统处理,屈服强度与抗拉强度均有不同幅度的上升,而伸长率和冲击功有小幅下降,正火控冷系统对提高正火钢板的合格率与正火钢板的档次具有重要意义。更多还原

【Abstract】 The control cooling system for medium & heavy plate normalizing was introduced.Its constitute and characteristics of the mechanical equipments and automatic control system were illustrated in detail.Normalized properties of several kinds of steel plate were comparatively studied.The results show that the yield strength and tensile strength of the normalized steel plate increase after control cooling treatment,and the elongation percentage and impact work decrease a little.The normalizing control cooling system has significant improving the qualified rate and the grade of the steel plate.更多还原
