Copper is widely used in industry, daily necessities, architectural decoration and even art fields, with strong corrosion resistance. This article is to bring you the copper belt production process of science.
Ingredients: According to different brands of alloy elements, according to the actual requirements of the ratio, preliminary processing.
Smelting: To melt the ingredients in a melting furnace. At the same time need to do pre-furnace analysis, generally chemical analysis and light analysis, according to the analysis results timely adjust the ratio and feeding.
Ingot casting: up method, semi - continuous casting, horizontal continuous casting, iron mold casting, etc. Semi-continuous casting: refers to the molten water down, the advantages of good precision. Up drawing method: refers to the molten water up drawing, the advantages of better precision.
Horizontal continuous casting: refers to the direct extraction of molten water, cooling directly on the mill, rolling into billet, the shortcomings of precision is not good. Iron mold casting: refers to the molten water directly into the iron mold, the disadvantage of poor precision.
Milling: Surface treatment of ingot.
Hot rolling: It means that the bad ingot is rolled without annealing after heating and before cooling.
Straightening-milling: The ingot surface is rough and the internal structure is loose.
Cold rolling: After the billet is heated and cooled, it is rolled while annealing.
Annealing: bell furnace annealing is generally used for semi-finished products; The annealing is uniform but controlled by thickness, and the hardness is controlled by annealing time.
Pickling: clean the dirt after annealing, generally after annealing need to be pickling.
Fine (medium) rolling: the surface is very smooth, the internal structure is more uniform and close.
Cleaning and leveling: determine the flatness of the board.
Longitudinal shear or transverse shear: The copper strip to be divided should be longitudinal shear and winding, and the plate should be transverse shear at this time.
Inspection: mechanical properties and chemical composition testing.
Packing and warehousing: products qualified for quality inspection shall be marked and registered in warehousing as required.
