An electrode cylinder for a ferroalloy high-power DC electric furnace

Abstract

The invention belongs to the technical field of electric furnace equipment, and specifically relates to an electrode cylinder for a ferroalloy high-power DC electric furnace, which includes an electrode cylinder body, an electrode connecting seat and a hook, and uniformly arranged electrodes are fixedly connected to the inner surface of the electrode cylinder body Connecting seat; the surface of the electrode connecting seat is provided with heat conduction holes; the upper surface of the electrode cylinder body is hung with hooks; the number of the hooks is two, and the left and right are symmetrically arranged; the two hooks The same suspension rope is connected between them; the lower surface of the electrode cylinder body is connected with an electrode connection seat; through the present invention, the electrode cylinder is effectively connected using a crane to automatically engage and connect. After the connection is completed, due to the electrode cylinder itself Due to the action of gravity, it will be automatically and firmly engaged, and the risk of rollover before the electrode cylinder is welded is reduced, ensuring the life, health and safety of the staff. During the engaging process, there is no need for auxiliary staff, and the work will not be injured in the event of a decoupling accident. personnel.

Description

technical field [0001] The invention belongs to the technical field of electric furnace equipment, and in particular relates to an electrode cylinder for a ferroalloy high-power DC electric furnace. 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, etc. Compared with the fuel furnace, the advantages of the electric furnace are: inside the furnace The atmosphere is easy to control; the material is heated quickly; the heating temperature is high; the temperature is easy to control; the production process is easier to realize mechanization and automation; the labor hygiene conditions are good; the thermal efficiency is high; [0003] The electrode cylinder is used as equipment on the electric furnace, and its internal electrode connectio...

Problems solved by technology

[0006] In order to make up for the deficiencies of the existing technology and solve the problem in the prior art, the electrode cylinder needs to be hoisted directly above the consumable electrode by a crane. Then the welding workers will directly weld between the electrode cylinder and the consumable electrode. During the hoisting process, workers need to assist in the operation under the electrode cylinder. When the lifting rope shakes, the electrode cylinder is easy to swing, and the electrode The swing of the cylinder is easy to hurt the staff below, especially when the electrode cylinder is hoisted or installed, the decoupling accident will pose a serious threat to the life of the staff below, and the direct and simple engagement between the electrode cylinder and the electrode connection seat, hoisting After the hook is removed, the electrode barrel is unstable and prone to rollover accidents. During the welding process, welding flashes or sparks can easily enter the inside of the electrode barrel through the gap between the electrode barrel body and the electrode connection seat, affecting the electrode. The normal operation of the cylinder, and during the welding process, the weld seam is directly exposed to the external environment, and a large amount of sparks splash out, which not only pollutes the environment on the top of the electric furnace, but also has problems such as the risk of causing fire. The present invention proposes a ferroalloy high-power Electrode cartridge for DC electric furnace
