In order to ensure the normal use of the intermediate frequency furnace, to extend the life of the equipment, should be regularly tested on all parts of the intermediate frequency furnace, intermediate frequency furnace operators must often look at each cooling road in the water flow and water pressure is in a normal working condition. To regularly tighten each part of the connecting bolts, nuts, to avoid the occurrence of poor contact phenomenon. Otherwise, it is easy to cause a bad effect on the components, and to plan the regular maintenance of the hydraulic station motor.
1. Regularly check whether the sealing of the joints of the water cooling pipeline of the medium frequency electric furnace is firm or not
When using tap water or well water as the cooling water source of the medium frequency furnace, it is easy to accumulate scale, which affects the cooling effect. In the plastic water pipe aging cracks, should be replaced in a timely manner. Medium-frequency furnace device in summer operation, the use of tap water well water cooling is often prone to condensation phenomenon, should consider the use of closed water circulation cooling system. When condensation is serious, it should stop running.
2. Regularly check whether the wiring of the medium frequency furnace load is good and whether the insulation is reliable.
Regularly remove the accumulated dust in the power cabinet, especially the outside of the SCR tube core, to be wiped clean with alcohol. The operating frequency conversion device generally has a dedicated machine room, but the actual operating environment is not ideal. In the smelting and forging process, dust is very large, strong vibration; in the medium frequency furnace quenching process, the device is often close to the pickling and phosphating and other operational equipment, there are more corrosive gases, which will play a destructive role in the device components, reduce the device's dielectric strength, you can consider the use of good insulation, high temperature corrosion-resistant insulating varnish, such as the current has been widely used in the medium- and high-end furnaces on the TSC - L ultra-high temperature insulating varnish and APC - H insulating varnish. Insulating paint and APC - H + high temperature arc-resistant insulating paint. When there is a high level of dust accumulation, surface discharges of components often occur. Therefore, attention must be paid to often clean the original surface dust, to prevent failure.
3. Regular overhaul of the medium frequency furnace device
The intermediate frequency furnace device of the various parts of the bolt nut crimping inspection and fastening, contactor relay contacts are loose or poor contact, should be repaired and replaced in a timely manner, do not force the use of, to prevent causing greater accidents.
4. Regular testing of the rated voltage and current of the medium frequency furnace
This kind of regular testing can prevent and control the circuit is not working. To be very good to the intermediate frequency furnace on a regular basis to take good care of, this maintenance is to increase the duration of the intermediate frequency furnace is the key to the use of the term, as well as to protect the operator's personal safety is an important prerequisite. Because the whole working environment of the medium frequency furnace is in a kind of high temperature and high pressure and strong current conditions, so be sure to place the medium frequency furnace room for regular cleaning and cleaning.
