(LHM-90AB) IGBT medium frequency induction annealing machine (5-20Khz)

• This type structure is widely used in such asforging furnace,smelting furnace.This structure's advantage is low energy loss, high working efficiency. The disadvantage is the inductor(coil) length is long, normally 3 meters to 10 meters. and the inductor (coil) has a high voltage up to 550V and this voltage is not insulated, so when working, the inductor (coil) must have a very good insulation, the copper pipe can not be exposed in the air.

• This structure's advantage is more safe, the inductor's voltage is in a safety range which the copper can even exposed in the air. This structure's disadvantage is energy loss is high, the cost is high. The lower the frequency, the bigger the transformer will need, the cost is higher

• Hot forging aims to fabricate the work pieces of certain temperature (different materials require different temperatures) into other shapes through forging press with the help of punch press, forging machine or other equipments for instances, hot extrusion of watch case, watch flan, handle, mold accessory, kitchen and table ware, art ware, standard part, fastener, fabricated mechanical part, bronze lock, rivet, steel pin and pin.
• Hot fitting refers to the connection of different metals or metals with nonmetals through the heating based on the principle of hot expansion or hot smelting, for instances, embedded welding of copper core of computer radiator with aluminum sheet and speaker web, compound of steel and plastic tube, sealing of aluminum foil (tooth paste peel) motor rotorand sealing of tubular electric heating element.
• melting mainly aims to melt the metal into liquid by using the high temperature, which is applicable to the smelting of iron, steel, copper, aluminum, zinc as well as various noble metals.

Heat treatment (surface quenching):

• Quench for various hardware and tools, such as pliers, wrench, hammer, ax, screwing tools and shear (orchard shear).
• Quench for various automobile and motorcycle fittings, such as crankshaft, connection rod, pinton pin, chain wheel, aluminum wheel, valve, rock arm shaft, small shaft and fork.Various electric tools, such as axes and gear.
• Quench for machine tools, such as lache deck and guide rail.
• Quench for various hardware metal parts and machined parts, such as shaft gear (chain wheel) cam, chuck and clamp. Etc.
• Quench for hardware molds, such as small size mold, mold accessory and inner hole of mold

Annealing (tempering and modulation):

• Annealing of various stainless steel products, such as stainless steel basin, annealed and extruded can, annealed folded edge, annealed sink, stainless steel tube, tableware and cup.
• Annealing of various other metal work pieces, such as golf ball head, cue, brass lock, hardware copper fitting, kitchen knife handle, blade, aluminum pan, aluminum pail, aluminum radiator and various aluminum products.
