Description

Technical Field

[0001] The utility model relates to the technical field of quenching furnaces, in particular to a medium frequency induction quenching furnace for quenching processing. Background Art

[0002] The purpose of quenching is to transform the supercooled austenite into martensite or bainite to obtain martensite or bainite structure, and then temper it at different temperatures to greatly improve the rigidity, hardness, wear resistance, fatigue strength and toughness of the steel, so as to meet the different use requirements of various mechanical parts and tools. However, the existing medium-frequency induction quenching furnace for quenching lacks a device to filter the flue gas generated during quenching. Since the direct discharge of the exhaust gas generated during quenching is easy to cause air pollution, it is inconvenient to discharge it directly. Therefore, we have launched a new medium-frequency induction quenching furnace for quenching. Utility Model Content
