Medium frequency furnace has good reputation in smelting heating equipment, exquisite workmanship and environmental protection. It is a good tool for industrial production.
The intermediate frequency furnace used for the first time and in the future, the lining must be lined in the furnace body and sintered. Lining is divided into acid and alkaline lining according to raw materials and smelting requirements. Lining the furnace is to use quartz sand and other materials to make a maintenance layer along the inner wall of the furnace to isolate the induction coil between the melting material and the furnace body, and to maintain the induction coil. When lining the furnace, it should be noted that the average strength is strong, once finished, and once formed. After lining, the furnace needs to be baked at low temperature for a long time, so that it can be condensed into a consolidated whole and has considerable strength. It can not be affected by melt stirring and feeding impact. During sintering, we should follow the method of slow heating with low power and low temperature and continue baking for more than 36 hours to fully solidify. Black and white lining is the main prerequisite for the service life and safety of medium frequency electric furnaces.
After the lining of the furnace is finished. How to accurately and reasonably operate the intermediate frequency furnace is the key to the service life and safety. In general, first check the the operation and medium frequency electric furnace before use it, whether the water cooling system water is hysteresis or not, cooling water pressure and water temperature is normal, whether there is water leakage scene, the hydraulic system can operate normally. In the operation, we must be careful and careful not to disturb and touch randomly. One person operates, one person is guardianship, and no other one is allowed to enter the computer room to avoid electric shock. In the melting process, we must use dry melt materials, and make light feeding and feeding frequently. When the melting material in the furnace melted to the demand, it should be poured out in real time to prevent the high temperature from adding the furnace lining loss; diligently looking at, when the furnace body is found to be red on the outside, this is the precursor of the leakage furnace, and the medium frequency power supply should be shut down immediately and the molten material in the furnace should be poured out to prevent the occurrence of the leakage of the furnace. It should also be noted that when the lining becomes thin and can not be used continuously, the old lining should be destroyed and the new lining be redone to avoid leakage.
In addition, because the intermediate frequency furnace is used under high temperature, high voltage and high current. Therefore, we should often clean the dust in the engine room, the power cabinet and the induction coil to avoid the insulation and reduce the defects. Often check whether the cooling water flow and water pressure can be normal. Tighten fastening bolts and nuts of each part on time to avoid contact with defective parts. Regular protection of water cooling system pumping motor, hydraulic station motor, clean hydraulic oil, ensure normal water supply and supply of equipment. Check the extra voltage and current of the equipment on time to avoid maintenance of circuit failure. Timely, accurate and careful maintenance is the main guarantee for prolonging the service life and safety of intermediate frequency furnaces.
The intermediate frequency furnace is unique in the industry because of its own uniqueness and will have broader development space in the future.
