Description

Technical Field

[0001] The utility model relates to the technical field of electric arc furnace supporting components, in particular to a water cooling circulation device for an electric arc furnace electrode lifting structure. Background Art

[0002] An electric arc furnace refers to an industrial furnace that uses the heat generated by an electric arc to melt ores and metals. The energy of a gas discharge arc furnace is very concentrated when an arc is formed. For melting metals, electric arc furnaces have greater process flexibility than other steelmaking furnaces and are widely used. The electrode assemblies of an electric arc furnace are generally clamped by a cross-arm structure, and the cross-arm structure is controlled by a matching lifting structure to control the lifting and lowering and thus control the position of the electrode.

[0003] The existing arc furnace electrode lifting structure has the following disadvantages when in use: the arc furnace electrode lifting structure is generally arranged on one side close to the arc furnace. During actual use, especially when the electrode is lifted and moved out of the arc furnace, the temperature of the working area will be greatly increased, and the lifting component will work in a high temperature state, which may easily lead to failure and damage of the lifting component after a long time. Therefore, we propose a water-cooling circulation device for the arc furnace electrode lifting structure. Utility Model Content

The corrugated hose can be telescopically deformed and end rings and sealing rings C are arranged on both ends. The sealing ring C is respectively fitted to the end of the cross arm and the end of the hydraulic cylinder. When the hydraulic assembly is running, the hydraulic rod is telescopically extended, which will drive the expansion and contraction of the corrugated hose.
