Annealing furnace

quenchingthermalchamber

The cover and trolley of the series of electric furnace are welded by steel plate and section steel. Soft contact between the trolley and furnace lining can sharply reduce thermal radiation and connective thermal losses so as to guarantee the furnace leakproofness. The furnace body is built with high temperature-resistant light bricks and insulating bricks. The equipment is mainly applied to the heating technology of large carbon steel and alloy steel parts, such as the heating, annealing, normalizing, quenching & tempering; surface quenching and tempering; stress relieving annealing by welding, etc. Furnace door is controlled to go up and down by up and down of the rolling wheel on the guide rails and is sealed with the domestic advanced spring compression mechanism so as to ensure that when closing, the fiber of furnace door can be matched with the furnace body and sealed tightly, and the fiber will not be fractioned in the closing and opening process of furnace door. The power of furnace door and trolley is provided by the electric motor and planet-cycloid retarder, which has controlled brake function. Each active mechanism in the electric furnace is installed with interlocking control, that is, after the furnace door is opened, the power used to heating components will be cut off automatically, and meanwhile, the power used for moving the trolley is recovered; after the furnace door is closed, the power used for moving the trolley will automatically cut off and meanwhile, the power used for heating components is recovered. In this way, accidents caused by misoperation can be avoided.
