High frequency heat treatment equipment uses electromagnetic induction to generate eddy current heating to heat the workpiece surface. It is widely used because of its high production efficiency, low energy consumption, easy to realize automatic production, less pollution and safety. Compared with the old high-frequency electronic tube equipment, the safety performance of the new high-frequency induction heating equipment is greatly improved, and there is no potential impact of high voltage and electromagnetic wave radiation. We need to pay attention to the following matters during operation:
01 only the designated trained staff can operate the high-frequency induction heating equipment, and the person in charge of the operation shall be designated. For safety, it is best to wear insulated shoes, insulated gloves and other specified protective articles to prevent high temperature.
02 the operator must be familiar with the operating procedures of high-frequency induction heating equipment. Before startup, check whether the equipment cooling system is normal. Power can be transmitted only after it is normal, and operate in strict accordance with the operating procedures.
03 all doors shall be closed before work, and the doors shall be equipped with electrical interlocking device to ensure that power cannot be transmitted before the doors are closed. After the high voltage is closed, do not move behind the machine at will, and do not open the door.
04 the workpiece shall be deburred, scrap iron and greasy dirt, otherwise it is easy to arc with the inductor during heating. The arc light generated by arc striking will not only damage vision, but also easily damage sensors and equipment.
05 high frequency induction heating equipment shall be kept clean, dry and dust-free. In case of any abnormality during work, first cut off the power switch, and then check and eliminate the fault. Special personnel must be assigned to repair the high frequency induction heating equipment.
06 when using high-frequency induction heating equipment matched with quenching machine tool, the safety regulations related to electrical, mechanical and hydraulic transmission shall be observed. Prevent toppling when moving the quenching machine.
In order to prevent the explosion and injury of large workpieces during power frequency induction heating, the operation procedures of power frequency heat treatment and corresponding process procedures of large workpieces must be strictly observed during operation. Large workpieces shall be subject to ultrasonic flaw detection one by one. Workpieces with defects such as white spots, serious segregation and looseness found after flaw detection shall not be heated with power frequency equipment. Burrs, iron filings and oil stains shall be removed from the workpiece to prevent arcing. During production operation, the person in charge must be designated, and the operator must be familiar with and abide by the operating procedures of power frequency equipment.
