2The 12, before with drying oven heating electrolysis copper coin, remove the dirt settling (like copper beans, verdigris etc.) on the electrolysis copper coin.
The technique means of the inventive method realizes goal of the invention through following mechanism.
1) electrolysis copper coin (high purity is better) is through heating, after the dedusting, the surface impurity of electrolysis copper coin and moisture removal, prevent that copper coin from dropping into smelting furnace after, chemical reaction at high temperature takes place in water:
Decompose the oxygen that comes out and fuse in copper liquid, can cause copper water oxygen level to increase.
Series of chemical can take place in the charcoal in the smelting furnace and restitutive protection's gas:
Through above-mentioned reaction, reduced the oxygen level in the copper water.The cladding thickness of charcoal can directly influence the oxygen level of copper water, and when charcoal covered deficiency, CO was not enough in the fusing furnace gas; Cause reduction insufficient, when charcoal covers when too much, hydrogen can't contact copper water smoothly; Also can cause reduction insufficient, cause to effectively reduce copper water oxygen level.
2) copper water is through being lower than the holding furnace that the subsurface runner of copper water flows into sealing, and even flow also has been full of the nitrogen protection gas that contains 0.5%-4.5% hydrogen to the coating chamber that links to each other with holding furnace (crucible oven) in the holding furnace then, and following chemical reaction can take place:
Through above-mentioned reaction, further reduced the oxygen level in the copper water again.
Ceramic baffle plate in the holding furnace can be selected corundum ceramic material for use, and the effect of baffle plate is to prevent that the copper ashes that swims in the holding furnace surface from flowing into coating chamber, otherwise can cause casting in bronze bar surface to have copper ashes to adhere to, and influences surface quality.
3) a thinner copper bar passes from a coating chamber bottom that is communicated with holding furnace, forms thicker casting in bronze bar at copper bar surface attachment copper water.Also be full of the nitrogen protection gas that contains 0.5%-4.5% hydrogen in the coating chamber, played reductive action on the one hand, also completely cut off airborne oxygen on the other hand.The copper bar through the processing that strips off the skin (processing that strips off the skin is that the layer of material that copper bar surface oxygen content is high is removed), guaranteed that the copper bar oxygen level before the dip-coating was minimum before getting into the coating chamber bottom, could guarantee that the copper bar that final production is come out has lower oxygen level.
4) cooling room of casting in bronze bar above coating chamber carries out continuous online cooling; Through regulating each section water yield; Control casting in bronze bar crystallization velocity also has been full of the nitrogen protection gas that contains 0.5%-4.5% hydrogen in the cooling room simultaneously, and following chemical reaction can take place this process:
The effect of shielding gas will contain that the oxygen that at high temperature decomposes out because of water coolant brings the copper bar into, prevent that copper bar oxygen level from increasing.
5) through overcooled casting bar, copper bar surface gets into milling train and is rolled, because the copper bar surface temperature that gets into before the milling train has 500-900 ℃; For preventing the oxidation at high temperature of copper bar, also must be full of the nitrogen protection gas that contains 0.5%-4.5% hydrogen in the milling train, simultaneously in the operation of rolling; The copper powder on copper bar surface and oxide compound and copper bar are peeled off; Must be in time with its removal, otherwise can in following one roll operation of rolling, embed the copper bar, cause copper bar surface injury; Also can increase copper bar oxygen level, need this moment to adopt emulsion that pickling is carried out on copper bar surface.
6) the copper bar after rolling cools off once more, gets into the take-up rolling, and the copper bar surface temperature control that gets into take-up is between 35-80 ℃.This moment, temperature was too high, can cause the oxygen uptake in air of copper bar, and along with temperature raises, the oxygen uptake degree is more serious, just can't produce the oxygen-free copper bar that satisfies the 2-8PPM scope.
Enforcement below in conjunction with production line explanation the inventive method shown in Figure 1.
Copper coin 26 (referring to Fig. 3) uses charging roller 1, feeding cart 2, rollgang 3 to send into smelting furnace 4 after treatment, and 4 pairs of copper coins of smelting furnace carry out heat fused.Copper liquid liquid level is higher in the smelting furnace 4, thereby copper liquid gets into the holding furnace 5 that is connected.Holding furnace 5 connects with adjacent coating chamber 6, and copper liquid gets into coating chamber 6 through holding furnace.When smelting furnace 4 quits work, can coating chamber 6 liquid levels be risen through trace inclination whole combination stove (referring to Fig. 2, combination stove comprises smelting furnace 4, holding furnace 5, coating chamber 6).The raw copper bar is drawn (referring to 4) through stripping off the skin and the feeding from coating chamber 6 bottoms of straightening device 18 backs from the upper end through drawing wire machine 7.The copper bar possibly can't pass coating chamber 6 bottom moulds because of joint is excessive, can use swager 8 earlier with the joint drawing-down, carries out bar again.After casting in bronze bar 31 after the coating is drawn through going into a gear 9; Go into the speed that a gear 9 gets into milling train 10 in upright arrangement through the control of casting in bronze bar tension force size; 10 pairs of casting in bronze bars of milling train in upright arrangement are rolled with emulsion and dash the pouring cooling after getting into, and the emulsion after the intensification gets into the 14 use cooling water heat exchanges of emulsion cooling system and cools off.Get into out a gear 11 behind the rolling casting in bronze bar 31, go out a gear 11, get into take-up 12 at last, carry out take-up through tension force size adjustment pulling speed.The intact copper bar of take-up forms web-like and gets into finished product roller-way 13.The part finished product can get into the female bar e Foerderanlage 15 of circulation as the female bar of raw material, produces again.The copper bar exterior skin that produces that strips off the skin can be collected through scrap wire lapper 17, and different volume copper bar raw materials need engage quantity-produced and use copper knock-off joint machine 16 joints.
Among Fig. 2-4: TG1 inductor block 19 and TG2 inductor block 21 utilize the eddying effect heat fused stove of electric current.FW inductor block 20 heat tracing stoves, copper liquid 25 flows into coating chamber 6 through the burning casting passage 22 that is communicated with from holding furnace 5.When in combination stove, adding copper coin 26, loading door 24 is opened.When whole body of heater moved, insulation bell 23 was in closing condition, and body of heater air outlet 27 is in opened condition simultaneously.Copper liquid 25 liquid levels height and feed back to system in low level inductor block 28 and high-order inductor block 29 induction holding furnaces 5, thus decision adds copper coin 26 fusing or inclination bodies of heater.In the whole production line operational process, constantly charge into restitutive protection's gas of the ratio of modulating through each body of heater mouth of pipe, thereby the atmosphere atmosphere that guarantees shielding gas in each body of heater or reducing gas is stable to each body of heater.
