Features of induction heating furnace:
1. Induction heating furnace has fast heating speed, high production efficiency, no burning loss and oxidation decarburization
Less material and forging die cost. Since the principle of induction heating furnace is electromagnetic induction, the heating speed can be achieved by adjusting the frequency and current strength. Ordinary workers can carry out continuous work of forging tasks ten minutes after working with intermediate frequency induction diathermy furnace, without requiring professional furnace burning workers to burn and seal the furnace in advance. There is no need to worry about the waste of heated billets in coal and gas furnaces caused by power failure or equipment failure. Due to the fast heating speed of this heating method, there is little oxidation. The oxidation burning loss of forgings heated by medium frequency is only 0.5%, the oxidation burning loss heated by gas furnace is 2%, and the coal burning furnace is 3%. The medium frequency heating process saves materials. Compared with the coal burning furnace, each ton of forgings can save at least 20-50 kg of steel raw materials, and its material utilization rate can reach 98%. Process energy saving, medium frequency heating, specific gravity oil heating, energy saving 31.5%~54.3%, energy saving 5%~40% than gas heating. The heating quality is good, which can reduce the scrap rate by 1.5% and increase the productivity by 10%~30%. Because the heating method is uniform and the temperature difference between the core and surface is very small, the service life of the forging die is also greatly increased in forging, which extends the service life of the die by 10%~15%, and the surface roughness of the forging is also less than 50um.
2. The induction heating furnace is heated evenly, the temperature difference between the core and surface is very small, the temperature control precision is high, and the automation degree is high, which can realize full automatic operation. Because the heat of induction heating furnace is generated in the workpiece itself, it is easy to achieve the requirements of uniform heating and small temperature difference between core and surface. The application of temperature control system can realize the accurate control of temperature and improve the product quality and qualification rate. The selection of automatic feeding and automatic discharging sorting devices, matched with the forging main machine with high automation and efficiency, together with special control software, can realize the automation of the forging production line and give full play to the production capacity of the forging main machine.
3. The working environment of induction heating furnace is superior, the working environment of workers and the image of the company are improved, pollution-free, and energy consumption is low. Compared with coal furnace, induction heating furnace does not produce strong light, smoke, dust and other pollution when using medium frequency induction diathermy furnace for heating in forging production. Compared with ordinary flame furnace, the furnace has high thermal efficiency. Workers will no longer be baked and smoked by the coal stove, but can meet the requirements of various indicators of the environmental protection department, and establish the company's external image and the future development trend of the forging industry. Induction heating furnace is an energy-saving heating method in electric heating furnace. The power consumption of a ton of forgings heated from room temperature to 1100 ℃ is less than 360 degrees.
