Questions about billet induction heating equipment

If there is a problem in the use of billet induction heating equipment, how do you deal with it? Is there a better or good way to deal with it? If not, please see the following:

Billet induction heating equipment is widely used in modern industrial production, but many people do not understand the tips of its induction heating heat treatment. FOREVER Electromechanical is a manufacturer of induction heating equipment with high skills and strong strength. Today, we are really analyzing this question.


(1) Some of the active joints of the billet induction heating equipment are all sealed with O-ring, and some of them are cooled by water.

(2) When the billet induction heating equipment disposes of titanium alloy, nitrogen should not be used as the cooling gas, because titanium and nitrogen react at high temperature, forming the golden titanium nitride.

(3) The vacuum tempering furnace probably has fast cooling equipment. The pressure of cooling water is about greater than 0.2Mpa, and the flow should be adjustable.

(4) The curing of billet induction heating equipment shall be in vacuum or filled with pure nitrogen to avoid aspiration and moisture absorption when not in use.

(5) The pressure rise rate of domestic billet induction heating equipment shall not be greater than 1.33Pa/h, and the specification of some foreign companies is 0.67Pa/h

(6) Vacuum heating is mainly based on radiation, and the workpiece is about the same distance in the furnace.

(7) During the heating process, the workpiece and the data in the furnace will be deflated to reduce the vacuum.

(8) The heating temperature of vacuum tempering, vacuum annealing, vacuum solution treatment and vacuum aging is usually the same as that of conventional treatment.

(9) When the workpiece is quenched in vacuum, vacuum quenching oil should be used, which has a low saturated vapor pressure.

(10) Cooling gas: 99.995% nitrogen is usually used for steel, 99.999% nitrogen or argon is used for high-temperature alloy, and 99.995% argon is used for titanium alloy.
