What are the advantages of high frequency heating furnaces?
High-frequency heating furnace, as an important equipment in the field of induction heat treatment, has been gradually applied to the quenching of workpieces such as gears, ring gears, bores and shafts; and through-heat forging of round steel, bar stock, bolts and nuts, etc., but for Many friends say that the understanding of high-frequency heating furnace is not so profound. The advantages of high-frequency heating furnace are briefly described below.
1. Rapid heat treatment, induction heating time in seconds, generally within 2-10S, the production cycle is also short, especially in the case of tempering or induction tempering, this process is similar to the machining process, so the modern induction Quenching equipment has been arranged on the production line or on the automatic line.
2, energy-saving heat treatment, its energy consumption has great advantages compared with carburizing, nitriding, quenching and tempering, energy saving, when the difference between the quality of the workpiece quenching part and the overall quality is greater, its advantages are more obvious .
3 , clean heat treatment, quenching liquid used for induction quenching, generally water, or an aqueous solution with additives, so when quenching, there is almost no soot, environmental protection and no pollution, improving the production space environment.
4,  high-frequency heating furnace surface quenching, can make the workpiece has a hard outer shell, tough core, so it can replace a part of carburizing, quenching and nitriding process, saving alloying elements of materials, due to short heating time, Less oxide scale and less deformation.
5,  the workpiece can be partially quenched, it can accurately heat the part of the workpiece to be quenched, especially in the case of using the magnetizer and the use of high power density, the effect will be more significant.1
