Resistance furnace with rapid cooling device

Abstract

The invention discloses a resistance furnace with a rapid cooling device. The resistance furnace comprises a main box, a bottom plate, an inner furnace body, a first rapid cooling box, a second rapid cooling box, an air cooling box, a water cooling plate and a heat conduction plate; the position, close to the middle end, of the top of the bottom plate is fixedly connected with the main box, a control box is arranged on the right side of the main box, and the first rapid cooling box is arranged on the left side of the main box; the second rapid cooling box is arranged on the rear side of the main box, the air cooling box is arranged at the position, close to the middle end, of the front side of the bottom plate, air conveying grooves are formed in the upper side and the lower side of the air cooling box correspondingly, supporting frames are fixedly connected to the rear ends of the air conveying grooves correspondingly, wind power motors are arranged at the positions, close to the middle end, of the supporting frames correspondingly, and the front ends of the wind power motors are in transmission connection with fan blade shafts through couplings; and a first pushing box is arranged at the left end of the inner wall of the first rapid cooling box. The resistance furnace with the rapid cooling device relates to the technical field of resistance furnace devices, the problem that the rapid cooling effect is affected due to structural damage caused by high temperature when the rapid cooling device is used for a long time is solved, and the uniform cooling effect of the rapid cooling device on the resistance furnace at different operation high temperatures is improved.

Description

technical field [0001] The invention relates to the technical field of resistance furnace devices, in particular to a resistance furnace with a rapid cooling device. Background technique [0002] Resistance furnace is an industrial furnace that uses electric current to heat the electric heating element or heating medium in the furnace, thereby heating workpieces or materials. , metal heat treatment heating, brazing, powder metallurgy sintering, glass ceramics roasting and annealing, low melting point metal melting, sand mold and paint film drying, etc. The resistance furnace is an electric furnace with the Joule heat generated by the current passing through the conductor as the heat source. The furnace uses electricity as a heat source, converts electrical energy into heat energy through electric heating elements, and heats the metal in the furnace. The ratio of resistance furnace to flame has high thermal efficiency, up to 50-80℅. The thermal system is easy to control, and ...
