Mainly used for the well type furance, the trolley furance, the box furnace, the salt bath furance and other kinds of electric furance heating work piece quenching.

Structure description:
    Quenching Oil 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. When the room temperature is low, the electric heater automatic connection heating quenching oil, hot controls automatically after the underheating warm, causes the quenching oil temperature constant temperature in the craft hardening temperature.
