Heating of the Quenching Medium

A complete quenching tank should be equipped with a heating device to achieve temperature control of the medium in accordance with the process requirements. In order to achieve the best cooling effect.

A quenching tank with water or salt water as a quenching medium, usually heated by means of water vapor.

Alkaline water solution, polymer water solution and quenching oil, generally using tyroelectric heating tube.

In the heater of quenching oil, the load power of the heating pipe should be less than 1.5w/cm2 to prevent the oil from overheating locally, causing the aging of the oil or the formation of a coke layer with poor thermal conductivity on the surface of the heating pipe, affecting the cooling of the electric heating element, and even causing the electric heat element to overheat and burn.

For quenching oil tanks, an electric heating device is usually installed on the outside or bottom of the groove, and a tyroid electric heating tube is also inserted inside the groove.

The following points should be noted when choosing a heater:

1 For a top-inserted tyrospile heater, set up sufficient non-heating areas to prevent the heating section from catching fire or burning if it is exposed to over-burning outside the medium, depending on the fluctuation of the liquid surface.

2 The surface load of the tyrosic electric heater depends on the type of medium to be heated and the flow (mixing) of the medium.

3 Heating tubes made of copper or copper alloys are not allowed, as copper or copper alloys accelerate the oxidation and polymerization of mineral oil.

4 Heating tube power, water solution tank according to the weight of the solution 10-15kw / ton (2 hours temperature rise 20 degrees C.
