1. Process introduction

Medium frequency furnace is a kind of equipment that turns alternating current rectification into direct current and then reverse into intermediate frequency current, generating intermediate frequency magnetic field through the coil, so that the metal is heated and melted in the magnetic field. In the melting process, the medium frequency furnace will produce a large amount of heat. If the heat control is improper, it may lead to overheating, affecting its normal operation and service life, so cooling equipment / system will be equipped to protect the normal operation of the process. The following are several intermediate frequency furnace processes requiring cooling equipment / system:

Melt metal:

In the process of smelting the metal, the medium frequency furnace will produce a large amount of heat, if the heat control is not appropriate may cause the metal to overheat, affecting its quality and performance. Using a water chiller for temperature control can effectively control the temperature in the furnace and ensure the quality of metal smelting.

Heat treatment process:

In the heat treatment process, the workpieces need to be heated and cooled to change their internal structure to improve their hardness and wear resistance. Using the chiller for temperature control can accurately control the temperature change during the heating and cooling process to ensure the stability and reliability of the heat treatment process.

Melt alloy:

During the melting of alloys, different kinds of metals need to be mixed together and melted at high temperatures. Using the chiller for temperature control can effectively control the temperature in the furnace and ensure the composition and performance of the alloy.

2. The refrigeration system of medium frequency furnace usually includes the following parts

Refrigeration compressor:

The refrigeration compressor is the core component of the refrigeration system, which presses the refrigerant to reduce its temperature and pressure, so as to create a low temperature environment.

Condensator:

Condenser is the heat dissipation component in the refrigeration system, which releases heat by cooling the high-temperature refrigerant gas into a liquid.

Expansion valve:

Expansion valve is a throttling component in the refrigeration system, which adjusts the pressure and temperature of the refrigeration system by controlling the flow of refrigerant.

Evaporimeter:

An evaporator is a heat-absorbing component in a refrigeration system, which lowers its temperature by absorbing the heat from the cooled object.

In the medium frequency furnace, the refrigeration system is usually combined with the cooling water circulation system to maintain the normal operation of the equipment. When the internal temperature of the equipment is too high, the refrigeration system will start to ensure the normal operation of the equipment by reducing the internal temperature of the equipment. It should be noted that the refrigeration system of the medium frequency furnace needs to be designed and configured according to the specific models and specifications of the equipment to ensure that it can effectively control the operating temperature of the equipment and ensure the normal operation and service life of the equipment. At the same time, the refrigeration system also needs to be maintained and maintained regularly during use to ensure its normal operation and extend its service life.
