Abstract
A production process of a copper-ferrum alloy plate (or row, bar, pipe) comprises steps of adding copper-ferrum intermediate alloy into a proper quantity of electrolytic copper in accordance with the standard of 10% of silver content and 0.5% of zinc content, controlling the temperature of a furnace at 1,080-1,100 DEG C, stirring and performing thermal insulation to keep alloy composition uniform, casting to obtain a blank, heating with a heating furnace, hot rolling with a rolling mill, vacuum annealing, and finish grinding to obtain a qualified product. The production process can maximally reduce production cost and can meet the requirements in national standards; and has the characteristics of high strength, good elasticity, good wear resistance, good cold and hot processing properties, and simple and convenient production process.
Description
Technical field: the production technology that the present invention relates to a kind of copper-iron alloy plate (row, rod, pipe).
Technical background: the non-ferrous metal processing enterprise in China, need to use have in a large number that the cold and hot working performance is good, intensity is high, good springiness, copper-iron alloy plate that anti-wear performance is good.Need production cost low on the one hand, also require it to have good cold and hot working performance, intensity height, good springiness, material that anti-wear performance is good on the other hand, and how to produce the copper-iron alloy plate that complies with the national standard requirements, make it should satisfy requirement cheaply, meet the needs of production again.
Summary of the invention: purpose of the present invention will provide the production technology of a kind of copper-iron alloy plate (row, rod, pipe) exactly, it can have good cold and hot working performance, intensity height, good springiness, characteristic that anti-wear performance is good, can reduce production costs again, enhance productivity.The object of the present invention is achieved like this, the production technology of copper-iron alloy plate (row, rod, pipe), it is characterized in that: be that cathode copper with copper content 〉=99.95% joins melting in the low-frequency furnace, temperature is controlled between 1080 ℃-1100 ℃, and the standard of pressing iron content 10%, zinc content 0.5% adds an amount of copper iron intermediate alloy; Stirring, intensification, melting, temperature are controlled at 1130 ℃-1180 ℃, and insulation is calm, makes its inner uniform ingredients, the stokehold sampling, and it is qualified to detect chemical analysis with atomic absorption instrument, is cast into blank; Sawing, ingot blank are adopted the oil burner heating after the assay was approved, and temperature is controlled at 850 ℃-880 ℃, the hot-rolling mill hot rolling, and hot-rolled temperature is controlled at 820 ℃-850 ℃; Blanking calculates the blanking size according to finished size; Pickling is cleaned, and pickling cleans up about 30 minutes again in 20% sulfuric acid solution; Roll in the middle milling train, roll crown is controlled at 0.25mm; Vacuum drying oven annealing, annealing temperature is controlled at 650 ℃-680 ℃, and the time was controlled at 4-5 hour; Sanding machine cleans processing; Finishing mill finish rolling, roll crown is controlled at 0.15mm, guarantees copper-iron alloy plate surface smoothness, thickness deviation; Passivation Treatment is adopted on the surface; Sawing as requested, leveling, check, packing, warehouse-in.Production technology of the present invention not only can reduce its production cost to greatest extent, and the institute's requirement that can be up to state standards, and production technology is simple, convenient.
The specific embodiment: the production technology of copper-iron alloy plate (row, rod, pipe), it is characterized in that: be that cathode copper with copper content 〉=99.95% joins melting in the low-frequency furnace, temperature is controlled between 1080 ℃-1100 ℃, and the standard of pressing iron content 10%, zinc content 0.5% adds an amount of copper iron intermediate alloy; Stirring, intensification, melting, temperature are controlled at 1130 ℃-1180 ℃, and insulation is calm, makes its inner uniform ingredients, the stokehold sampling, and it is qualified to detect chemical analysis with atomic absorption instrument, is cast into blank; Sawing, ingot blank are adopted the oil burner heating after the assay was approved, and temperature is controlled at 850 ℃-880 ℃, the hot-rolling mill hot rolling, and hot-rolled temperature is controlled at 820 ℃-850 ℃; Blanking calculates the blanking size according to finished size; Pickling is cleaned, and pickling cleans up with clear water about 30 minutes again in 20% sulfuric acid solution; Roll in the middle milling train, roll crown is controlled at 0.25mm; Vacuum drying oven annealing, annealing temperature is controlled at 650 ℃-680 ℃, and the time was controlled at 4-5 hour; Sanding machine cleans processing; Finishing mill finish rolling, roll crown is controlled at 0.15mm, guarantees copper-iron alloy plate surface smoothness, thickness deviation; Passivation Treatment is adopted on the surface; Sawing as requested, leveling, check, packing, warehouse-in.During concrete enforcement, adopt copper content greater than, equal 99.95% cathode copper and join melting in the low-frequency furnace, add amount of copper iron intermediate alloy during melting, because of the fusing point of iron higher, temperature will could melt in the time of 1450 ℃ fully, in copper water, separate than infusibility, must press iron content 10%, the ratio of zinc content 0.5% is made copper iron intermediate alloy earlier, joins in the smelting furnace, and its addition will be according to high Fe content 2.3-3%, low iron 1.5-1.8% standard adds, insulation is calm, and the time was controlled at 1 hour, was cast into blank; Sawing, check, underproof product melts down melting again; Ingot blank after the assay was approved adopts oil burner to heat, and temperature is controlled at 860 ℃, the hot-rolling mill hot rolling, and hot-rolled temperature is controlled at 830 ℃; Blanking calculates the blanking size according to finished size; Pickling is cleaned, and pickling is 30 minutes in 20% sulfuric acid solution, cleans up with clear water again; Roll in the middle milling train, roll crown is controlled at 0.25mm; Vacuum annealing, annealing temperature are controlled at 660 ℃; Sanding machine cleans processing; Finishing mill finish rolling, roll crown is controlled at 0.15mm, guarantees copper-iron alloy plate surface smoothness, thickness deviation; Require controlling dimension and tolerance according to drawing; Carry out surface passivation and handle, prevent the surface oxidation of copper-iron alloy plate, sawing is tested after becoming standardized product, will note the non-oxidation layer during check, does not have scuffing, no sand holes, at last warehouse-in.Processing technology of the present invention has reduced its production cost significantly, and can satisfy enterprise's conduction, heat conductivility.
