Description
Technical field: the present invention relates to a kind of strengthened ultra-thin rod copper belt and working method thereof.
Background technology: strengthened ultra-thin rod copper belt is one of main raw of making by scatterer, consider from production cost, the strength of materials, material solidity to corrosion, optimal heat-radiation belt thickness is 0.038～0.05mm, little, in light weight, the perfect heat-dissipating of pipe rock radiator volume with such production, technical feature requires high, belong to the hard state product, the technical indicator that project demand reaches is: thickness deviation is 0.05
-0.05Mm, electric conductivity is no less than 85%, and softening temperature is not less than 380 ℃, and tensile strength is 380～420N/mm
2, microhardness is 100～145g/mm
2Its alloying element ratio of band that " Shanghai non-ferrous metal " reflected in first-phase " development of ultra-thin water tank copper strips TOA alloy " literary composition in 1998 is Sn (0.10-0.16%), P (0.005%), Zn (0.02-0.07%), Ni (0.2%), thickness of strip is 0.06mm, softening temperature is greater than 380 ℃, (by 4 minutes), microhardness are 110～140g/mm
2, electric conductivity is 80%, tensile strength is not less than 380N/mm
2Its alloying element of band that reflects in the literary composition of Beijing Copper Material Factory achievement storehouse " development of high-copper water tank copper strips " is Sn, P etc., do not reflect concrete ratio, thickness of strip is 0.06mm, softening temperature is not less than 380 ℃, (by 4 minutes), electric conductivity is not less than 75%, and the product that above-mentioned working method is produced all can not meet the requirements of technical indicator.
Summary of the invention: the present invention produces the problem of strengthened ultra-thin rod copper belt poor-performing and a kind of strengthened ultra-thin rod copper belt and working method thereof is provided in order to solve existing working method.A kind of strengthened ultra-thin rod copper belt is characterized in that: described strengthened ultra-thin rod copper belt is to add tin, zinc, phosphorus trace element in fine copper, and adding quantity is tin 0.03～0.09%, zinc 0.03～0.12%, phosphorus 0.002～0.008%.The working method of this strengthened ultra-thin rod copper belt comprises casting and cold working two portions, and its technical process for casting is: after the fusing of at first will preparing burden heated up, Jiang Tongshui poured holding furnace into and carries out cast; Wherein, described melting process is: add cathode copper and insulating covering agent to smelting furnace, wait the fusion that heats up, add tin and stir, add again zinc, phosphor-copper stir after immediately the water of falling copper go into holding furnace; It is 1300 ℃ that described tin adds fashionable temperature.The copper strips stable performance of adopting this method to produce, thickness is 0.045mm, and tolerance is-0.004mm, and electric conductivity is not less than 85%, and softening temperature is not less than 380 ℃, tensile strength at 380～420N/mm
2Between, microhardness is at 110～130g/mm
2Between, and the passband difference is little, main performance index is satisfied with softening temperature and is not less than 380 ℃, electric conductivity and is not less than 80% belt making process requirement.
Embodiment: this strengthened ultra-thin rod copper belt is to add tin, zinc, phosphorus trace element in fine copper, and adding quantity is tin 0.03～0.09%, zinc 0.03～0.12%, phosphorus 0.002～0.008%.The production of strengthened ultra-thin rod copper belt divides casting and cold working two portions, its technical process for casting: batching → fusing → intensification → copper water is as holding furnace → cast → mill face → batch → shear.
Embodiment: add trace element in fine copper: tin 0.03～0.09%, zinc 0.03～0.12%, phosphorus 0.002～0.008%, cathode copper selects 1 for use
#Cathode copper, and remove limit portion and the hangers that the knot grain is arranged, electric conductivity can be controlled in 78～90%, and softening temperature is not less than 380 ℃.Its processing requirement is satisfied in this trace element interpolation fully.Melting process is to add cathode copper and the insulating covering agent → intensification fusion → adding tin → zinc that stirs → add → adding phosphor-copper → stir to smelting furnace, and the water of falling copper is gone into holding furnace immediately; Specifically be that cathode copper is added smelting furnace, and add red-hot charcoal and cover, treat the cathode copper fusing after, temperature reaches 1300 ℃, adds tin; After fully stirring, add zinc and phosphor-copper, pour copper water into holding furnace then and carry out cast.The introductory note journey is adopted in cast, the short pause, suitably counter midway being pushed away, the cast parameter is drawn journey 12.5mm～15mm, counter pushing away: 0.5mm～1.0mm, pause 2.2s～3.0s, casting speed: 2.8～3.2mm/s, casting temp: 1210 ℃～1230 ℃, water coolant requires: inflow temperature: 15 ℃～30 ℃, leaving water temperature(LWT): 40 ℃～55 ℃, cooling water pressure: 0.5Mpa.Copper water enters the transition chute that carries out the preheating baking and seal with charcoal by copper smelting furnace, reduces the oxygen uptake of copper water, pours holding furnace then into.To guarantee that in the docking of crystallizer and holding furnace crystallization docks with holding furnace well, because the alloy liquid temp is higher, between 1190 ℃～1250 ℃, if the butt joint material refractoriness of selecting for use does not reach service requirements, easily melt at work or peel off, efflorescence, cause the joint leak, the refractoriness of therefore docking material requires to reach 1300 ℃.To guarantee that in addition good between cooling plate and the graphite cake contacts, graphite cake working face smooth finish reaches standard-required and the levelness of crystallizer assembling.
By the strengthened ultra-thin rod copper belt steady quality that adopts this method to produce, thickness is 0.045mm, and tolerance is-0.004m, and electric conductivity is not less than 85%, and softening temperature is not less than 380 ℃, and tensile strength is at 380～420N/mm
2Between, microhardness is at 110～130g/mm
2Between, and the passband difference is little, stable performance, and electric conductivity is 85%, and main performance index satisfies softening temperature and is not less than 380 ℃, and electric conductivity is not less than 80% belt making process requirement.
