Copper strip manufacturing procedure
Making active ingredients: According to the alloy component composition of different brands, make percentages according to actual needs and execute preliminary handling.
Smelting: Thaw the components in the melting furnace. At the very same time, heater evaluation is required. Usually, chemical analysis and optical spectrum analysis, and the proportion and feeding are readjusted in time according to the evaluation results.
Ingot spreading: There are up attracting approaches, semi-continuous casting, straight continuous casting, iron mold casting, etc. Semi-continuous casting describes the descending flow of liquified water, with the benefit of the most effective precision. The higher drawing approach describes the upward circulation of molten water, with the advantage of great accuracy. Horizontal continuous casting describes the direct drawing of liquified water, cooling down and directly on the rolling mill, and rolling it into coils, with the downside of inadequate precision. Iron mold spreading refers to the direct putting of liquified water right into the iron mold, with the disadvantage of the worst precision.
(copper strip)
Milling: Surface area processing of ingots.
Hot rolling refers to the rolling of poor ingots after home heating yet before cooling down, without annealing.
Straightening-milling: the surface area of the ingot is harsh, and the inner structure is loose.
Cold rolling describes the process of heating and cooling the billet while annealing and rolling.
Annealing: Bell furnace annealing is usually made use of for semi-finished items; annealing is consistent but regulated by density, and hardness is managed by annealing time.
Pickling: Clean the dirt after annealing, and pickling is usually called for after annealing.
Ending up (intermediate) rolling: The surface area is really smooth, and the internal structure is fairly consistent and tight.
Cleansing and leveling: Figure out the monotony of home plate surface area.
Longitudinal shearing or transverse shearing: The copper strip to be split into strips is longitudinally sheared and rolled at this time, and the plate is transversely sheared currently.
Assessment: Conduct mechanical buildings and chemical make-up examinations
Product packaging and warehousing: Inspect items with qualified high quality, mark and register them for warehousing as required.
Method for treating discoloration of copper strip surface area
Control the concentration of acid throughout pickling. When the acid focus is high, the residual acid attached to the surface of the copper strip is challenging to wash off and increases the air pollution of the cleaning water, which is very easy to causes the residual acid concentration in the cleansing water to be too high, making the copper strip after cleaning most likely to alter shade. When figuring out the focus of the pickling solution, try to minimize its concentration as much as feasible while being able to cleanse the oxide layer on the surface of the copper strip.
Control the conductivity of pure water. Control the conductivity of distilled water that is, manage the content of hazardous materials such as chloride ions in pure water.
Control the conductivity of hot cleaning water and passivation agent. The increase in the conductivity of hot cleansing water and passivation agent is mostly due to the residual acid brought right into the running copper strip. Under the problem of making certain the top quality of the distilled water made use of for cleansing, regulating the conductivity suggests regulating the amount of recurring acid.
Guarantee that the copper strip is dry. Partially close the outlet of the air pillow furnace coiling, and utilize a dehumidifier and a/c in the local shut device to regulate the humidity and temperature level of the copper strip throughout curling within a certain variety.
