The high-temperature trolley type resistance furnace is a periodic resistance furnace, which is mainly used for heating rolls or other alloy steel parts below 1200℃.
The utility model comprises a furnace body, a thermal insulation layer and a furnace lining, a shelving brick on the furnace lining, a heating element on the shelving brick, a heating element under the bottom plate of the furnace body, a furnace body connected with the furnace door and the furnace door lifting mechanism, a trolley, a driving device and a track are arranged around the trolley and an automatic sealing device of the furnace body, and a furnace door sealing mechanism is arranged on the furnace body. The sealing effect of the furnace is good, and the quenching, normalizing and tempering of mechanical parts and castings can be completed automatically.
Various heat treatment processes such as high temperature trolley furnace effect and sintering process of gold and steel oil drill bit. It has no pollution to the environment, is highly energy saving, can continuously work at 1200 ° C high temperature, uniform furnace temperature, high temperature control precision, tight seal, can realize microcomputer intelligent control, and the dolly type resistance furnace can accurately complete any heat treatment process curve and sintering process.
