Copper strip manufacturing procedure
Making ingredients: According to the alloy aspect composition of various brands, make percentages according to actual demands and execute initial handling.
Smelting: Thaw the ingredients in the melting heater. At the same time, heating system analysis is required. Typically, chemical analysis and optical spectrum analysis, and the percentage and feeding are changed in time according to the analysis results.
Ingot casting: There are upward attracting techniques, semi-continuous casting, horizontal continual spreading, iron mold casting, and so on. Semi-continuous spreading refers to the descending flow of molten water, with the benefit of the very best accuracy. The higher drawing method refers to the upward circulation of liquified water, with the advantage of excellent accuracy. Straight constant casting refers to the direct drawing of liquified water, cooling down and straight on the rolling mill, and rolling it into coils, with the drawback of bad accuracy. Iron mold and mildew casting describes the straight putting of liquified water right into the iron mold, with the downside of the worst precision.
(copper strip)
Milling: Surface processing of ingots.
Warm rolling describes the rolling of poor ingots after home heating but before cooling down, without annealing.
Straightening-milling: the surface area of the ingot is rough, and the interior structure is loose.
Cold rolling refers to the process of home heating and cooling down the billet while annealing and rolling.
Annealing: Bell heater annealing is generally used for semi-finished products; annealing is uniform yet controlled by density, and hardness is managed by annealing time.
Pickling: Clean the dust after annealing, and pickling is typically needed after annealing.
Ending up (intermediate) rolling: The surface area is really smooth, and the internal framework is relatively uniform and limited.
Cleaning up and leveling: Identify the monotony of home plate surface area.
Longitudinal shearing or transverse shearing: The copper strip to be divided into strips is longitudinally sheared and rolled right now, and the plate is transversely sheared right now.
Evaluation: Conduct mechanical homes and chemical structure tests
Packaging and warehousing: Inspect products with competent top quality, mark and register them for warehousing as called for.
Approach for dealing with staining of copper strip surface area
Control the concentration of acid during pickling. When the acid focus is high, the recurring acid attached to the surface area of the copper strip is difficult to wash off and speeds up the air pollution of the cleaning water, which is very easy to causes the recurring acid focus in the cleansing water to be too expensive, making the copper strip after cleaning up more probable to transform shade. When identifying the concentration of the pickling solution, attempt to minimize its concentration as long as feasible while being able to clean the oxide layer externally of the copper strip.
Control the conductivity of pure water. Control the conductivity of distilled water that is, control the material of damaging substances such as chloride ions in distilled water.
Control the conductivity of warm cleansing water and passivation agent. The rise in the conductivity of warm cleaning water and passivation representative is primarily as a result of the recurring acid brought into the running copper strip. Under the problem of making certain the top quality of the distilled water used for cleaning, regulating the conductivity indicates controlling the quantity of residual acid.
Make sure that the copper strip is dry. Partially shut the outlet of the air pillow furnace coiling, and use a dehumidifier and ac unit in the regional closed gadget to control the humidity and temperature level of the copper strip throughout coiling within a particular array.
