Maintenance method of intermediate frequency induction melting furnace

The maintenance of the intermediate frequency induction melting furnace includes the maintenance of the electrical system, the hydraulic system and the water cooling system. First, the maintenance of the electrical system requires daily inspection of the electrical components in the intermediate frequency power supply cabinet, and regular inspection of the components in the cabinet and the copper bars. Remove the dust; tighten the connecting bolts of the copper bar every week, check whether the plywood of the copper bar is discolored or loose, and solve the problem in time; fasten the foot bolts of the smoothing reactor every month .

Secondly, in the maintenance process of the hydraulic system, regular inspection and repair should be strengthened according to the frequency of use of the components and its own characteristics. The leakage test of the oil cylinder and valve must be carried out every day, and the oil pump and oil level must be tested regularly every week. Carry out an oil quality test every six months to ensure that the oil temperature in the mailbox is below 55°C. Finally, we must pay attention to the maintenance of the water cooling system. According to survey data, more than half of the failures of the intermediate frequency induction melting furnace are caused by the water cooling system.

When performing water cooling maintenance, you must first do spot inspections and patrol inspections, check water temperature, water flow, water pressure, etc. in time, and find problems in time. In addition, strictly control the temperature of the inlet water. If the inlet water temperature is low, make the cold electrical Condensation drops appear on the surface of the component, which may eventually cause grounding, leakage, short circuit, and cause safety accidents.
