Abstract

The utility model relates to a double-joint electrode water-cooled holder of a corundum smelting furnace. The double-joint electrode water-cooled holder of the corundum smelting furnace consists of a holder steel body housing and a double-joint holder copper inner wall which are welded into a closed cavity structure by a copper steel composite welding method, wherein the double-joint holder copper inner wall, the welded steel housing, the end parts of two steel plates with butted end parts, the side walls of the steel housing and inner supporting arms are commonly welded into a closed cavity structure. When the corundum smelting furnace works, flowing water is injected into a water inlet pipe arranged at one end of one of the steel housing side walls and flows out of a water outlet pipe along water guide holes formed in the inner supporting arms to take away heat generated by the arc-shaped conductive contact end during operation, so that the temperature of the arc-shaped conductive contact end during operation ranges from 50 and 70 DEG C, electricity consumption is reduced, the aim of saving electricity is fulfilled, and the defects in the prior art are overcome.

Description

Corundum smelting stove twin adapter electrode water-cooled holder

Technical field

The utility model relates to corundum smelting stove electrod assembly field, is specifically related to a kind of corundum smelting stove twin adapter electrode water-cooled holder; By water-cooled cooling, the holder that makes corundum smelting stove electrode in low-temperature condition, to reduce current drain, is realized the object of economize on electricity when work.

Background technology

Corundum smelting stove consumes electric energy in process of production in a large number, is genuine electric-tiger.The critical piece of traditional corundum smelting stove was divided into wall copper coin, middle copper pipe, soft copper strips, the holder etc. of connecting.As everyone knows, voltage is lower, wire is longer, resistance is larger, consumes highlyer, and the line loss of wire is also higher.Root is according to data: the contact power consumption in each hour of 5000K V A transformer is 10 degree, and every transformer calculates by 12 joints, per hour with regard to loss of electricity 120 degree.Conductive resistance is directly proportional to temperature, and by theoretical every every high once resistance difference 0.004, copper bar temperature is 120～180 ℃; Especially the holder of smelting furnace electrode, is the key joints of as easy as rolling off a log generation high temperature, and temperature during work is much larger than 180 ℃; Burn out sometimes even part of appliance; Therefore, design a kind of corundum smelting stove twin adapter electrode water-cooled holder---by water-cooled cooling, the holder that makes corundum smelting stove electrode when work in low-temperature condition, to reduce electric quantity consumption, the object that realizes economize on electricity, this has positive realistic meaning for corundum smelting industry.

Utility model content

The purpose of this utility model is to provide a kind of corundum smelting stove twin adapter electrode water-cooled holder---pass through water-cooled cooling, make holder in when work in low-temperature condition, to reduce current drain, realize the object of economize on electricity, overcome the deficiencies in the prior art and defect.

For achieving the above object, the utility model has adopted such technical scheme: a kind of corundum smelting stove twin adapter electrode water-cooled holder, is comprised of a holder steel body case and a copper inwall of twin adapter holder that adopts copper steel complex welding method to be welded into airtight cavity structure with it; It is characterized in that: described holder steel body case is comprised of a welding box hat, two box hat sidewalls, inner support arm, end docking steel plate, strengthening steel slabs; The both sides of welding box hat are welded with respectively box hat sidewall, are welded with inner support arm in structure, are prefabricated with at least two water-guiding holes on inner support arm; The two ends of one of them box hat sidewall are respectively equipped with water inlet pipe and outlet pipe;

The two ends of welding box hat respectively symmetrical end are welded with end docking steel plate, and the both sides of junction are welded with boss, and end docking steel plate is provided with at least two screws; On one of them end docking steel plate, be connected with strengthening steel slab; The copper inwall of twin adapter holder is arcuate structure, and arcuate structure is welded on the docking end of steel plate, two ends, the end along portion, inner support arm of box hat sidewall; Dock with welding box hat, two ends steel plate end, box hat sidewall along portion, inner support arm, be jointly welded into an airtight cavity body structure;

Two parallel holder terminal plates extend and are welded on the inner side of the copper inwall of twin adapter holder through the top of welding box hat, the extension of two holder terminal plates forms inner support arm.

Adopt after such structure, holder steel body case has enough intensity, and the copper inwall of twin adapter holder has good electric conductivity; Adopt the compound welding method of copper steel that the two is welded together, intensity and electric conductivity have both, and cheap for manufacturing cost, are comparatively desirable combinations.

End, box hat sidewall, the inner support arm of the copper inwall of twin adapter holder, welding box hat, two end docking steel plates are welded into an airtight cavity body structure jointly; When corundum smelting furnaceman does, the water inlet pipe arranging from one end of one of them box hat sidewall injects flowing water, flowing water is along the water-guiding hole arranging on inner support arm, from outlet pipe, flow out, the heat producing while taking away the work of arc conduction contravention, the temperature while making the work of arc conduction contravention is between 50-70 °; (conductive resistance is directly proportional to temperature) thus reduce electric quantity consumption, realize the object of economize on electricity, overcome the deficiencies in the prior art and defect.
