Industrial electric furnace professional manufacturers and their product performance characteristics

Electric furnace equipment is usually a complete set, including electric furnace body, power equipment (electric furnace transformer, rectifier, frequency converter, etc.), open and close, auxiliary electrical industrial furnace

Vacuum equipment, test and control instrument (electrical instrument, thermal instrument, etc.), automatic regulating system, industrial furnace

Mechanical equipment (feeding and discharging machinery, furnace tilting device, etc.). The main components of industrial electric furnace are: industrial furnace masonry, industrial furnace exhaust system, industrial furnace preheater and industrial furnace combustion device.

The following is the push plate furnace in the industrial furnace as an example, to introduce the main technical requirements and work structure of the industrial furnace.

Intermediate frequency electric stove

Intermediate frequency furnace is a kind of will power frequency 50 hz alternating current into intermediate frequency (above 300 hz - 1000 hz) power supply device, the three-phase alternating current (ac) power frequency, after rectification into direct current, then laid adjustable intermediate frequency electric current, direct current supply by capacitance and induction coil in through the intermediate frequency alternating current, generate high density magnetic field lines in the induction coil, induction coil, and cutting in cheng fang of metal materials, produce a lot of eddy current in the metal materials. Because the principle of medium frequency induction heating is electromagnetic induction, its heat is generated in the workpiece itself, ordinary workers can use medium frequency electric furnace to work after 10 minutes to carry out forging task of continuous work, do not need to burn furnace professional workers in advance and furnace sealing work. Due to the high heating speed of this heating method, oxidation is very little. The oxidation loss of intermediate frequency heating forgings is only 0.5%. The oxidation loss of gas furnace heating is 2%, and the coal furnace reaches 3%. Intermediate frequency furnace heating speed, medium frequency furnace production with high efficiency, less intermediate frequency furnace oxidation decarburization, extend the service life of mould medium frequency furnace, intermediate frequency furnace working environment is superior, intermediate frequency furnace to improve Labour standards and the company's image, intermediate frequency furnace pollution-free, low-power intermediate frequency furnace and medium frequency furnace melting speed, medium frequency furnace energy-saving effect is good, intermediate frequency furnace burning less, low energy consumption and the uniform mixing function, melting temperature and metal composition, intermediate frequency electric furnace heating start-up performance is good, good working environment, intermediate frequency furnace air furnace, furnace can be 100% full.

Characteristics of the equipment

Saving features

Heating speed, high production efficiency, less oxidation decarburization, save material and cost, extend the service life of mould due to the principle of electromagnetic induction medium frequency induction heating, the heat inside the workpiece itself, ordinary workers with intermediate frequency electric furnace to work after ten minutes for the task of forging work continuously, without burning furnace professional workers for burning furnace and furnace work ahead of time. Due to the high heating speed of this heating method, oxidation is very little. The oxidation loss of intermediate frequency heating forgings is only 0.5%. The oxidation loss of gas furnace heating is 2%, and the coal furnace reaches 3%. Its material utilization rate can reach 95%. Due to uniform heating and small temperature difference between core and gauge, the forging life is greatly increased in forging. The surface roughness of the forging is also less than that of the 50um process, and the energy saving of intermediate frequency heating is 31.5% ~ 54.3% as compared with oil heating, and 5% ~ 40% as compared with gas heating. Good heating quality can reduce the rejection rate by 1.5%, increase the production rate by 10% ~ 30% and prolong the life of the die by 10% ~ 15%.
