Temperature-controllable box type quenching furnace

Abstract

The invention discloses a temperature-controllable box type quenching furnace, and belongs to the technical field of quenching furnaces. The temperature-controllable box type quenching furnace comprises a quenching box main body. A filter plate assembly is obliquely arranged in the quenching liquid box. an electric telescopic rod is arranged in the center of the inner wall of the bottom of the quenching liquid box; the top of the electric telescopic rod penetrates through the filter plate assembly and is provided with a working partition plate; a heating device is arranged in the inner cavityof the quenching box main body; an exhaust fan is arranged at the top of the inner cavity of the first shell; ventilation channels are uniformly arranged in the top of the quenching box main body; andan adjusting screw rod is inserted in the left side of the shell II. According to the quenching furnace, a heating device is adopted and is matched with two branch pipes, and the heating wires in thebranch pipes can be controlled to conduct heating through the control switch; meanwhile, the exhaust fan is arranged to be matched with the ventilation channels, when the internal temperature is excessively high, the exhaust fan is started to extract and dissipate heat in the quenching furnace, the adjusting screw rod is arranged to be matched with the sealing baffle, the heat dissipation amountis controlled and the controllable internal temperature of the quenching furnace is realized.

Description

technical field [0001] The invention relates to the technical field of quenching furnaces, in particular to a temperature-controllable box-type quenching furnace. Background technique [0002] The quenching furnace is a non-standard electric furnace specially designed according to user requirements. It is mainly used for heat treatment such as quenching and heating of various workpieces in the aluminum industry. Quenching is to heat the workpiece and then cool it rapidly in quenching media such as water, oil or other inorganic salts and organic aqueous solutions. For the temperature required by some workpieces, the traditional quenching furnace cannot be adjusted effectively, and the quenching furnace is in After use, it is necessary to dissipate the heat inside the quenching furnace to take out the workpiece, which takes a long time and reduces work efficiency. Moreover, the existing quenching furnace cannot filter the quenching liquid. When the workpiece is quenched and co...

Quenching is to heat the workpiece and then cool it rapidly in quenching media such as water, oil or other inorganic salts and organic aqueous solutions. For the temperature required by some workpieces, the traditional quenching furnace cannot be adjusted effectively, and the quenching furnace is in After use, the workpiece needs to dissipate the heat inside the quenching furnace to take out the workpiece, which takes a long time and reduces work efficiency. Moreover, the existing quenching furnace cannot filter the quenching liquid. When the workpiece is quenched and cooled, impurities will remain in the quenching liquid. , easy to block the waterway, for this reason, we propose a temperature-controllable box-type quenching furnace
