High-frequency gear hardening equipment, also known as high-frequency heating furnace or high-frequency welding equipment, generally converts 50Hz AC current to high-frequency current above 10MHz, used for rapid heating of metal materials. The skin effect of high-frequency current quickly heats the workpiece and melts metal. Due to the high frequency, the high-frequency furnace is used for smelting metals with high-frequency alternating current, where electromagnetic fields convert rapidly, thus generating greater heat power compared to low-frequency devices.
The specific applications of high-frequency gear hardening equipment include quenching of various gears, sprockets, and shafts; quenching of automotive parts such as halfshafts, leaf springs, shift forks, valves, rocker arms, and ball joints; brazing equipment for power transmission towers using induction heating.
Quenching processes are widely applied in modern mechanical manufacturing industries. Important components in machinery, especially steel parts used in automobiles, aircraft, and rockets, almost always undergo quenching treatment. To meet a wide range of technical requirements for different parts, various quenching processes have been developed. For example, according to the treated area, there is overall quenching, partial quenching, and surface quenching; according to whether the phase transformation is complete during heating, there is complete quenching and incomplete quenching (for hypo-eutectoid steels, this method is also called subcritical quenching); according to the content of phase transformation during cooling, there are分级quenching, isothermal quenching, and under-speed quenching, etc.
Quenching of various internal combustion engine components and reducer components; quenching treatment of machine tool guides in the machine tool industry (lathes, milling machines, shapers, presses, etc.), machine tool guide quenching equipment. Quenching of various hand tools such as pliers, knives, scissors, axes, hammers, etc. Internal wall quenching of concrete pump pipes, quenching of concrete delivery pumps, online gear quenching equipment for rams' horns hammers.
