The oil-quenching tank uses the steel plate structure, has the square shape, the rectangle, the circular, in the fuel tank the installment has the electric heating tube, outside the trough the installment has the oil pump, the stainless steel disc heat interchanger, the automatic oil constant temperature controls the warm cabinet, its principle of work: When the work piece enters fuel tank quenching to cause frequently the oil temperature elevates, the oil pump starts to work, sucks in the stainless steel disc heat interchanger fuel tank's in high temperature oil, this time cools the circulating water to put through automatically, carries on the heat transfer through disc heat interchanger's multi-layer stainless steel plate trough, causes the quenching oil which the process cools to return to the oil-quenching tank again, so moves back and forth the circulation, achieves the fuel tank to decrease temperature the goal.

淬火油槽采用钢板结构，有方形、长方形、圆形，油槽内安装有电加热管，槽外安装有抽油泵、不锈钢板式换热器，自动油恒温控温柜，其工作原理：当工件频繁进入油槽淬火引起油温升高时，油泵开始工作，将油槽内的高温油抽入不锈钢板式换热器，此时冷却循环水自动接通，通过板式换热器的多层不锈钢板槽进行换热，使经过冷却的淬火油再返回淬火油槽，如此往复循环，达到油槽降温目的。
