Problems solved by technology

However, due to the small size of the heating zone of the device, the furnace loading capacity is limited, which cannot meet the quenching requirements of large quantities of materials; in addition, because the device has to wait for the furnace tank to cool down before continuing to charge the furnace after quenching, the production efficiency is relatively low

Description

technical field [0001] The present invention relates to the technical field of heat treatment equipment, more specifically, to a vacuum quenching furnace. Background technique [0002] Quenching is a heat treatment process, which refers to a metal heat treatment process in which the metal workpiece is first heated to a certain temperature, then kept for a period of time, and then immediately immersed in the quenching medium for rapid cooling. The purpose of quenching is to transform the austenite in the metal into martensite or bainite, and then cooperate with tempering at different temperatures to greatly improve the rigidity, hardness, wear resistance, fatigue strength and toughness of the metal, so as to meet the Different use requirements for various mechanical parts and tools. The quenching process usually needs to be carried out in a specific device. Among them, the vacuum quenching furnace is a common quenching device. Due to the good heat insulation and sealing effe...
