淬火冷却是热处理车间的关键工序，对产品质量有决定性的影响，而冷却介质的温度是其主要影响因素之一。随着淬火件数量的增加，由工件传递到冷却介质中的热量增加，温度不断升高，因此冷却介质本身也有一个冷却问题。对于油类冷却介质，由于比热较低，当淬火件较多或淬火间隔
Quenching and cooling is the key process of the heat treatment plant, the product quality has a decisive impact, and the cooling medium temperature is one of the main influencing factors. As the number of quenched parts increases, the amount of heat transferred from the work piece to the cooling medium increases and the temperature rises continuously, so that the cooling medium itself also has a cooling problem. For oil cooling medium, due to lower specific heat, when quenching more or quenching interval
