1 Economical features

● Fast heating speed, high production efficiency, less oxidation and decarburization, saving materials and costs, and extending mold life

Since the heating principle of induction furnace is electromagnetic induction, its heat is generated in the workpiece itself. Ordinary workers can carry out the continuous work of forging tasks ten minutes after working with induction furnace, and do not need professional furnace burning workers to burn and seal the furnace in advance. Due to the fast heating speed of this heating method, there is little oxidation. The oxidation burning loss of induction heating forgings is only 0.5%, the oxidation burning loss of gas furnace heating is 2%, and the coal furnace heating is 3%. The induction heating process saves materials. Compared with the coal furnace, each ton of forgings can save at least 20-50 kg of steel raw materials. Its material utilization rate can reach 95%. Because the heating mode 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. The roughness of the forging surface is also less than 50um process energy saving. Induction heating can save 31.5%~54.3% of the energy for specific gravity oil heating, which is 5%~40% less than that for gas heating. With good heating quality, the scrap rate can be reduced by 1.5%, the productivity can be increased by 10%~30%, and the die life can be extended by 10%~15%.

2 Environmental protection characteristics

● Superior working environment, improved workers' working environment and company image, pollution-free and low energy consumption

Compared with the coal furnace, the induction smelting furnace will not be baked and smoked by the coal furnace under the hot sun any more, and can meet the requirements of various indicators of the environmental protection department, while establishing 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 furnace. The power consumption of a ton of forgings heated from room temperature to 1100 ℃ is less than 360 degrees.

The heating is uniform, the temperature difference between core and surface is very small, and the temperature control accuracy is high

The induction heating heat is generated in the workpiece itself, so the heating is uniform, and the temperature difference between the core and the surface is very small. The application of temperature control system can realize the accurate control of temperature and improve the product quality and qualification rate.

Characteristics of induction melting furnace

A. The smelting speed is fast, the power saving effect is good, the burning loss is small, and the energy consumption is low.

B. Self mixing function, smelting temperature and even metal composition.

C. Good working environment for electric heating.

D Good startup performance, 100% startup can be achieved when the furnace is empty or full

3 Other characteristics

The induction furnace has the advantages of small size, light weight, high efficiency, excellent hot working quality and favorable environment. It is rapidly eliminating coal fired furnace, gas fired furnace, oil fired furnace and ordinary resistance furnace, and is a new generation of metal heating equipment.

Induction furnace is the main equipment in the casting, forging and heat treatment workshop. Its stability, reliability and safety are the guarantee for the normal operation of the production line. Induction furnace has a good development prospect in the field of hot processing, such as heating furnace before forging, diathermic furnace, and induction heating used for diathermic, rolling, forging, bending, heat treatment (quenching), welding and other processes.
