The share plow is an important agricultural tool, and its function is to turn the soil to one side or turn the subsoil to the ground. Therefore, in the process of farming, the share plow has to bear huge friction. Many manufacturers use intermediate frequency induction hardening equipment to quench and heat-treat the ploughshare to improve its hardness, wear resistance and service life, and the effect is very good.
Medium frequency induction hardening equipment adopts voltage feedback series resonant circuit, adopts IGBT frequency conversion, the conversion efficiency is as high as 97.5%, compared with thyristor, it can save energy by 10%-30%, and it can start 99% successfully under any load, regardless of the output power. Size, power factor is always not less than 0.95, less high-order harmonic components, little impact on the grid, with the function of automatic frequency tracking, can always ensure high power factor in the whole process, has a complete protection circuit, and works reliably high. When it performs quenching heat treatment on the plowshare, the quenching speed is very fast, which effectively avoids the phenomenon of oxidation and decarburization of the plowshare during the quenching process, ensures the quenching effect of the plowshare, and makes the quenched plowshare have thicker toughness under the hard layer on the surface The area has good compressive internal stress, which makes the fatigue resistance and breaking capacity of the workpiece higher, which meets the working requirements of the plowshare.
The induction coil of the medium-frequency induction hardening equipment can be replaced freely, which enables the equipment to perform quenching heat treatment on plowshares, and quenching heat treatment on edge guards, harvester blades, hoes and other agricultural tools, realizing the multi-purpose of the equipment.
