Description
Technical field
The invention belongs to technical field of metallurgical equipment, relate in particular to a kind of conductive cross arm using on the industrial furnace of arc heating.
Background technology
Conductive cross arm is as the critical component of arc furnace, play a part to support and holding electrode, by electric energy by the short net of transformer secondary in electrode conducts to furnace shell, in furnace charge, produce powerful arc current, make to be heated up by melting thing.Conductive cross arm is arranged on support post conventionally, and its front end, by terminal clamp holding electrode, remains on exactly on the position of electrode centers circle electrode in lifting process.The weight of conductive cross arm is lighter, means that support post is made the actuating force of lift adjustment relatively less, and the load of electrode regulating guider is less, also makes the lift adjustment responding ability of support post be improved simultaneously.In arc furnace smelting procedure, due to electrode tip and formed powerful high-temperature electric arc between melting thing, can cause the vibration of conductive cross arm intense electromagnetic, therefore conductive cross arm also should have good Rigidity and strength.For heating up by melting thing with the arc-melting of peak efficiency, conductive cross arm also should have low resistance value and reactance value.In addition,, for adapting to high-temperature work environment, conductive cross arm inside is connected with cooling water, should reduce as far as possible in design the accumulation of static dust, to extend the life-span of conductive cross arm.As from the foregoing, electric arc furnace smelting technique to the requirement of conductive cross arm be lightweight, good rigidity, impedance is little, the life-span is long.
Traditional conductive cross arm is steel, and it separates support electrode and two kinds of functions of conduction, and support function is completed by the transverse arm main body with good rigidity being arranged on support post, and conducting function is completed by the water-cooling contact tube being arranged in transverse arm main body.Such conductive cross arm is feasibility and the fail safe that meets its electric conductivity, require the hot downtime of busbar connection work long, maintenance efficiency is lower, but owing to can producing intense electromagnetic vibration in conductive cross arm lifting process, and the arcing phenomena that produces of the effect such as dust in operational environment, easily cause and play electrical breakdown, the fault such as leak, need shut-down (breakdown) mainteance, maintenance capacity is very large, also increase electric energy loss, therefore this class conductive cross arm has the shortcoming that weight is large, impedance is high, the life-span is shorter, relatively takes up room simultaneously.
Copper steel composite conducting cross arm is the product of traditional all steel conductive cross arm upgrading, it is rectangle truss structure, it is the extexine copper coin conduction of utilizing copper-steel composite plate, thereby cancel the contact tube in conventional conductive transverse arm system, the conduction of conductive cross arm and two kinds of functions of support electrode are united two into one, this can reduce resistance value and the reactance value of conductive cross arm to a certain extent, improve electric conductivity, but because the copper coin in copper-steel composite plate is relatively thin, its conduction cross-sectional area is relatively little, therefore resistance value and reactance value are fundamentally improved not yet, and the total weight of copper-steel composite plate conductive cross arm is too large, electrode regulating performance is sensitive not.
All aluminium alloy conducting horizontal rod is to weld by aluminium alloy plate the box structure of making, and inner water flowing is cooling, simple in structure.Because transverse arm entirety is full-aluminum alloy, compared with copper steel composite conducting cross arm, conductive cross-sectional area is large, and reactance value diminishes, and conductivity is high, can improve the electrical efficiency of arc furnace, reduces electric energy loss.And the density of aluminium alloy is little, lightweight, because the total weight of all aluminium alloy conducting horizontal rod alleviates, and system resonance frequency is directly proportional to the sensitivity of electrode control regulator, reduces weight and improves exactly adjuster sensitivity, moving-mass and the inertia of rise fall of electrodes are reduced, thereby greatly improved the lift adjustment responding ability of electrode mast, and electrode lifting speed improves, eliminate the response of arc short circuit and accelerate, can reduce like this export license, realize and raise the efficiency and reduce costs.But the fusing point of aluminium is lower, transverse arm top be subject to thermal-flame and thermal-radiating affect larger, and the electric conductivity of aluminium is not so good as in fact the electric conductivity of copper, in order to improve electric conductivity, ensure job stability, just need to use the thicker conductive cross arm of size, simultaneously in order to improve intensity, reinforcement is also joined in inside, and the processing technology of aluminium is than steel and cuprate complex, conventionally need to use special welding processing equipment, and in order to prevent all aluminium alloy conducting horizontal rod aqueous corrosion that is cooled, need carry out electrification with magnesium alloy materials anticorrosion, to improve sheet material corrosion resistance, anti-corrosion material is changed once for 3～5 years, this not only directly increases processing and manufacturing cost, and follow-up maintenance leaves many problems.
