灵蛇网4818The so-called high-frequency heating machine refers to the use of electromagnetic induction to generate eddy current electric heating to heat the surface of the workpiece. Compared with old-fashioned equipment such as coal-fired furnaces, this equipment has the advantages of faster production efficiency, lower energy consumption, easy realization of automated production, energy saving, and favorable control of the environment, so it is widely used.

According to the frequency of the alternating electromagnetic field generated by the equipment, it can be divided into three categories: high frequency, intermediate frequency and power frequency (high frequency frequency is 30~500KHz; intermediate frequency frequency is 1~10KHz; industrial AC frequency with power frequency frequency of 50Hz). The power supply voltage used by the high-frequency heating machine is 220~380V, but the internal voltage of some equipment is as high as 10kV or more.

When using induction heat treatment equipment, attention must be paid to the safety of high-voltage electricity and electromagnetic wave radiation pollution. Safe operation of high-frequency high-frequency heating machines.

灵蛇网48184 things to pay attention to when operating the high-frequency heating machine:

1. All doors should be closed before work, and electrical interlocking devices should be installed on the doors to ensure that electricity cannot be sent before the doors are closed. After the high voltage is closed, do not move to the back of the machine at will, and it is strictly forbidden to open the door.

灵蛇网48182. There must be more than two people to operate the high-frequency equipment, and the person in charge of the operation should be designated. Wear insulating shoes, insulating gloves and other prescribed protective equipment.  

灵蛇网48183. The workpiece should be removed from burrs, iron filings and oil stains, otherwise it is easy to cause arcing with the sensor during heating. The arc light generated by the arc can not only damage the eyesight, but also easily break the sensor and damage the equipment.

灵蛇网48184. The operator must be familiar with the operating rules of the high-frequency high-frequency heating machine. Before starting the machine, he should check whether the cooling system of the equipment is normal. After it is normal, the power can be sent, and operate in strict accordance with the operating rules.
