Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the existing trolley-type resistance furnace, the gap between the trolley and the furnace body is manually sealed, which will increase the difficulty of work, and the sealing effect is poor, which will cause For the problem of heat loss and influence on heating effect, the present invention provides a thermal cycle trolley furnace, which uses an electric sealing device to seal the joint between the lining body and the thermal insulation bottom lining, with good sealing effect and long-lasting sealing, making It heats more evenly

Abstract

The invention relates to the technical field of heat treatment equipment, in particular to a heat circulation trolley furnace. The heat circulation trolley furnace includes a trolley, a furnace shell,a liner, a plurality of heating pipes, a hot air circulation device, an electric sealing device, a furnace door and a lifting mechanism. A diversion cover is an inverted-U-shaped diversion cover arranged in the opening direction of an annealing furnace. A return wind channel is formed between the diversion cover and the liner. A return wind opening is formed between the lower side of the diversion cover and a heat insulating bottom liner. A wind inlet matched with a drainage cover is formed in the top of the diversion cover. The wind inlet is in sealed connection with a wind outlet of the drainage cover. A heating pipe is arranged in the vertical direction and arranged in the return wind channel. The electric sealing device seals the junction between the liner and the heat insulating bottom liner. The heat circulation trolley furnace uses the electric sealing device to seal the junction between the liner and the heat insulating bottom liner, the sealing effect is good, sealing is durable, and heating of the heat circulation trolley furnace is made to be more even.

Description

technical field [0001] The invention relates to the technical field of heat treatment equipment, in particular to a heat cycle trolley furnace. Background technique [0002] The tempering furnace is used for tempering general metal parts in air and quenching, annealing and aging heat treatment for aluminum alloy die castings, pistons, aluminum plates and other light alloy parts. The shell is welded by steel plates and section steels. [0003] At present, the trolley-type resistance furnace mainly uses a furnace to heat parts. This heating method has some problems for heating parts of different sizes. Some larger equipment and parts need a larger furnace to heat, and this single furnace It cannot meet the heating requirements of different workpieces, and it is necessary to manufacture multiple desktop resistance furnaces of different sizes to achieve the goal. However, due to the large size of the desktop resistance furnace itself, such manufacturing greatly increases the pro...
