Abstract

The invention discloses a vacuum annealing furnace for steel. The vacuum annealing furnace for steel comprises a heat preserving furnace body, a vacuum furnace body and a furnace cover. The vacuum furnace body is arranged in the heat preserving furnace body. The opening end of the heat preserving furnace body and the opening end of the vacuum furnace body are covered with the furnace cover. A heating layer is arranged between the heat preserving furnace body and the vacuum furnace body. An electric heating element is arranged on the portion, where the heating layer is arranged, of the heat preserving furnace body. A heat insulation layer is arranged in the vacuum furnace body and located under the furnace cover. A sealing motor is arranged on the furnace cover. The lower portion of the sealing motor is connected with a fan. The furnace cover is further provided with a vacuum pumping port. The vacuum annealing furnace for steel is rapid in cooling speed and capable of saving time and improving the labor productivity; a vacuum unit is high in pumping rate, and the uniformity of furnace temperature and the using effect are good.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a vacuum annealing furnace for steel. Background technique [0002] Annealing furnaces are widely used in chemical industry, petroleum, food, metallurgy, machinery, light industry, electric power, shipbuilding, papermaking, mining, medicine, heat concentration and other industrial sectors. With the development of social productivity, it is more and more widely used in various industries.
