[0002] The trolley-type resistance furnace is mainly used for quenching, normalizing, annealing, aging and heat treatment of various mechanical parts for steel castings, auto parts, rolls, steel balls, metal structural parts, weldments, and various mechanical parts. With the development of industrialization in China, its The demand is increasing, and there are many types of trolley-type resistance furnaces on the market. For example, the document with the application number 201220568794.8 discloses a trolley-type resistance furnace, which has a furnace shell, a furnace door, a trolley and heating elements. The door has a furnace lining made of refractory fiber. The front of the trolley is equipped with a driving device and a traveling device for driving the trolley. The driving device is a self-propelled traction mechanism. The self-propelled traction mechanism includes a transmission mechanism and a chain. The transmission mechanism is installed On the frame at the head of the trolley, the transmission mechanism drives the wheels to run through the chain. The walking device is a semi-open bearing wheel structure. The heating element includes a heating contact, which is fixed at the tail of the trolley, which can adapt to the wider width. The large trolley furnace does not occupy the workshop area and does not need to lay pits. It is easy to manufacture and easy to lubricate the wheel shaft. When the trolley enters the furnace, the heating contacts can be well matched with the contacts installed at the lower part of the furnace body. However, this trolley-type resistance furnace cannot solve the problem of how to control the heating temperature in the furnace in real time during heating, reduce the heat loss in the furnace, prevent the heated object from falling, and reduce the radiation caused by high temperature to the human body.
