Description

Technical Field

[0001] The invention relates to the technical field of tempering furnaces, in particular to a high-efficiency tempering furnace. Background Art

[0002] Tempering is a heat treatment process in which the workpiece is heated to a temperature below Ac1 (the starting temperature of pearlite to austenite transformation during heating) after hardening, kept at this temperature for a certain period of time, and then cooled to room temperature. It is mainly used to reduce or eliminate the internal stress in the quenched steel part, or reduce its hardness and strength to improve its ductility or toughness.

[0003] Patent No. CN202320873079.3 discloses a tempering furnace, which can stir the water in the outer shell by installing a stirring mechanism on the outer side of the tempering furnace body. Injecting cold water into the gap between the outer shell and the tempering furnace body can accelerate the heat dissipation of the tempering furnace body. Injecting hot water will have a heat preservation effect, making it difficult for the heat in the tempering furnace body to dissipate, thereby achieving the heat preservation effect. Cold water or hot water is injected as needed. At this time, the water pump is connected to the power supply. Under the suction of the water pump, water enters the gap between the outer shell and the tempering furnace body through the connecting pipe, thereby achieving the effect of heat preservation or heat dissipation.

[0004] However, the existing tempering furnace cannot change the direction of the articles after placing them in the furnace, which causes uneven heating of the surface of the articles during high-temperature treatment, thereby reducing the high-temperature treatment effect of the articles sent into the box-type tempering furnace. In addition, the gas treatment mechanism of the tempering furnace works for a long time, resulting in a large amount of dust remaining inside, which is inconvenient for staff to clean; therefore, it does not meet the existing needs, and we have proposed a high-efficiency tempering furnace.
