Industrial electric furnace of self-cleaning structure

Abstract

The invention discloses an industrial electric furnace of a self-cleaning structure in the technical field of industrial electric furnaces. After a workpiece is molten and taken out, a cleaning device is placed into a furnace body to clean the inner wall of the furnace body, a cleaning cylinder can revolve around a supporting column and can rotate while revolving, furnace slag on the surface of the inner wall of the furnace body can be crushed by multiple sets of crushing cones, the furnace slag attached to the surface of the inner wall of the furnace body is conveniently crushed and does not need to be manually cleaned through tools, so that the safety of workers is guaranteed, the cleaning speed is increased, and the working efficiency is improved; and meanwhile, when the crushing cones crush the furnace slag, the crushing cones can shake up and down, on one hand, the number of crushing openings when the crushing cones crush the furnace slag is increased, the situation that the whole furnace slag on the inner wall of the furnace body cannot be crushed due to the fact that crushing openings of crushing cones to the furnace slag are small is avoided, and on the other hand, shaking of the crushing cones is beneficial to shaking off the crushed furnace slag.

Description

technical field [0001] The invention relates to the technical field of industrial electric furnaces, in particular to an industrial electric furnace with a self-cleaning structure. Background technique [0002] The electric furnace is a heating furnace that converts the electric energy in the furnace into heat to heat the workpiece. The electric furnace can be divided into resistance furnace, induction furnace, electric arc furnace, plasma furnace, electron beam furnace and so on. Compared with fuel furnaces, the advantages of electric furnaces are: easy control of the atmosphere in the furnace, fast heating of materials, high heating temperature, easy temperature control, easy mechanization and automation of the production process, good labor hygiene conditions, high thermal efficiency, good product quality, and It is more environmentally friendly and helps to alleviate the increasingly serious environmental problems. [0003] When the existing industrial electric furnace ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an industrial electric furnace with a self-cleaning structure to solve the above-mentioned background technology. When the existing industrial electric furnace heats and melts steel, slag and carbon deposits will adhere to the inner wall of the electric furnace. There are more and more slag attached, and the volume in the furnace is getting smaller and smaller, which affects the follow-up work. At present, the slag in the furnace is generally cleaned by workers using shovels or sticks to remove the slag, but when removing the slag When the electric furnace is cooled to room temperature, the temperature of the electric furnace will not cool down to room temperature, resulting in the safety of workers cannot be guaranteed during cleaning. If the electric furnace is cooled to room temperature, the slag will harden, which will increase the difficulty of cleaning, and manual cleaning Slow speed and low cleaning efficiency
