Features of Induction Furnace Series Heating Furnace
(1) The heating speed is fast, the production efficiency is high, the oxidation and decarbonization are less, and the cost of materials and forging dies is saved. Since the principle of intermediate frequency induction heating is electromagnetic induction, its heat is generated in the workpiece itself, ordinary workers can carry out continuous forging tasks ten minutes after going to work with intermediate frequency electric furnace, and no professional furnace burner is required to carry out furnace burning and furnace sealing work in advance. There is no need to worry about the waste of heated blanks of coal stoves caused by power failure or equipment failure. Due to the fast heating speed of the heating method, oxidation is very little, steel raw materials are saved by at least 20-50 kg per ton of forgings compared with coal-burning stoves, and the material utilization rate can reach 95%. Because the heating method is uniform in heating and the temperature difference between the core and the surface is extremely small, the service life of the forging die is greatly increased in forging, and the roughness of the forging surface is less than 50um.
(2) The working environment is superior, the working environment of workers and the company image are improved, pollution is free, and the energy consumption is low. Compared with coal stoves, induction heating furnaces will no longer be baked and smoked by coal stoves under the scorching sun and can meet various index requirements of environmental protection departments. At the same time, they will establish the company’s external image and the future development trend of the forging industry. Induction heating is the most energy-saving heating method in electric heating furnaces. The power consumption per ton forging heated from room temperature to 1100 ℃ is less than 360 degrees.
(3) Uniform heating, extremely small temperature difference between core and surface, and high-temperature control accuracy. Induction heating furnace has the advantages of small volume, lightweight, high efficiency, excellent thermal processing quality, and a favorable environment. It is rapidly eliminating coal-fired furnaces, gas-fired furnaces, oil-fired furnaces, and common resistance furnaces, and is a new generation of metal heating equipment.
