Environmental characteristics of medium frequency heating equipment

Medium frequency heating furnace is a kind of will power frequency 50 hz alternating current into intermediate frequency 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 the capacitor and inductor in the flow of 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.
Professional build medium frequency heating furnace/frequency diathermy equipment series of characteristics of heating furnace, heating speed, high production efficiency, less oxidation decarburization, save material and cost, extend the life of the mold.
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 heating mode heat up fast, so few oxidation, medium frequency heating forging of oxidation burning loss is only 0.5%, gas stove heating oxidation burning loss of 2%, coal-fired furnace reached 3%, intermediate frequency heating process saving material, every tons of forgings and burn coal stove compared to save steel raw materials for at least 20 to 50 kilos. The material utilization rate can reach 95%. Table due to the heating way heating uniformity, core temperature difference, so in terms of forging also greatly increase the service life of forging die, forging surface roughness is less than 50 um technology of energy saving, energy-saving 31.5% ~ 54.3%, the proportion of medium frequency heating oil heating than gas heating energy saving 5% ~ 40%. Heating quality is good, can reduce the rejection rate of 1.5%, increasing production rate of 10% ~ 10%, 10% ~ 15% extend the die life.
