AI Technical Summary

Technical Problem

On the Marpe heat treatment continuous production line, there are problems of equipment energy waste and idle capacity during the switching process between martensitic and bainitic quenching processes. In particular, the energy consumption of the quenching cooling salt tank is high, which affects the equipment utilization rate.

Method used

During process switching, by processing tempered products (42CrMo, 40# or 45# steel) and utilizing their own heat, the temperature of the heating furnace and quenching cooling salt bath is adjusted, achieving instant switching and continuous quenching cooling, reducing waiting time, and promoting rapid rise and fall of salt temperature.

Benefits of technology

It improved equipment utilization, reduced energy consumption, avoided equipment idle time, and enhanced production efficiency and energy utilization efficiency.

Abstract

本发明涉及热处理技术领域的一种用于马贝热处理连续生产线的节能加工方法,在马氏体和贝氏体淬火两种工艺方式切换时,切换时只要淬火加热温度具备满足调质产品加热温度,加热结束的调质产品不用等盐槽盐温升或者降到温,可采用生产线上的即时盐温连续进入盐槽进行淬火冷却,利用空档期加工调质产品,通过降低开始加热淬火介质的下限温度和提高开始强制淬火介质上限温度,充分利用工件淬火时释放的热量加热淬火介质,利用淬火介质的自然散热,减少对淬火介质强制冷却消耗的能量,这种热处理工艺技术一方面弥补了之前设备空耗所带来的产能闲置,使设备的产能得到充分释放,另一方面可以大幅减少淬火加热炉和盐槽等设备机构的能源空耗。
