Copper strip production process
Making ingredients: According to the alloy component composition of different brand names, make proportions according to real needs and perform preliminary handling.
Smelting: Thaw the active ingredients in the melting heating system. At the very same time, heating system evaluation is called for. Usually, chemical evaluation and optical range evaluation, and the percentage and feeding are readjusted in time according to the analysis results.
Ingot spreading: There are up drawing methods, semi-continuous spreading, straight continual casting, iron mold and mildew casting, and so on. Semi-continuous casting describes the descending flow of molten water, with the advantage of the most effective precision. The higher drawing technique refers to the upward flow of liquified water, with the advantage of good precision. Straight continuous spreading refers to the straight illustration of liquified water, cooling and straight on the rolling mill, and rolling it right into coils, with the disadvantage of poor accuracy. Iron mold casting describes the direct putting of liquified water into the iron mold, with the drawback of the worst precision.

Milling: Surface area processing of ingots.
Hot rolling describes the rolling of poor ingots after heating but prior to cooling down, without annealing.
Straightening-milling: the surface of the ingot is rough, and the interior structure hangs.
Cold rolling describes the procedure of heating and cooling the billet while annealing and rolling.
Annealing: Bell furnace annealing is usually utilized for semi-finished products; annealing is uniform yet controlled by density, and hardness is controlled by annealing time.
Pickling: Clean the dirt after annealing, and pickling is normally called for after annealing.
Finishing (intermediate) rolling: The surface area is really smooth, and the internal structure is relatively consistent and tight.
Cleansing and leveling: Establish the monotony of the plate surface.
Longitudinal shearing or transverse shearing: The copper strip to be separated into strips is longitudinally sheared and rolled at this time, and home plate is transversely sheared at this time.
Inspection: Conduct mechanical homes and chemical structure tests
Product packaging and warehousing: Evaluate products with qualified high quality, mark and register them for warehousing as needed.
Approach for treating 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 challenging to clean off and speeds up the contamination of the cleaning water, which is very easy to triggers the residual acid focus in the cleansing water to be too expensive, making the copper strip after cleaning more probable to change color. When establishing the focus of the pickling solution, attempt to minimize its focus as long as possible while having the ability to clean the oxide layer on the surface of the copper strip.
Control the conductivity of pure water. Control the conductivity of pure water that is, manage the web content of hazardous substances such as chloride ions in pure water.
Control the conductivity of hot cleaning water and passivation agent. The rise in the conductivity of warm cleansing water and passivation representative is mostly due to the residual acid brought into the running copper strip. Under the problem of making sure the quality of the distilled water made use of for cleaning, controlling the conductivity suggests managing the quantity of residual acid.
Ensure that the copper strip is completely dry. Partly close the outlet of the air padding furnace coiling, and utilize a dehumidifier and ac unit in the neighborhood shut tool to regulate the humidity and temperature of the copper strip throughout coiling within a specific range.
