碳素钢零件淬火时采用的盐水,温度不能过高,因此在连续生产时,为了保证质量常常将淬热了的盐水进行冷却后循环使用。通常由室外的盐水塔向淬火槽供给盐水,淬热了的盐水流到贮水池,再用水泵打到盐水塔冷却,如此循环。过去我厂是靠人工控制水泵开关来供水或停水,需要有人 Salts used in the quenching of carbon steel parts can not be too high in temperature, so when the continuous production is carried out, the quenched brine is often cooled for recycling to ensure quality. Salt water is usually supplied to the quench tank by an outdoor salt water tower. The quenched salt water flows to the water storage tank, and then is pumped to the brine tower for cooling to circulate. In the past I plant by manual control of the pump switch to water or no water, you need someone
