C12300 Copper Strip Price for Sale China production process:

Ingredients: According to the alloying element composition of different brands, the proportioning and preliminary processing are carried out according to the actual requirements.

Smelting: The ingredients are smelted in a smelting furnace. At the same time, pre-furnace analysis is required, generally including chemical analysis and optical analysis, and timely adjustment of the ratio and addition of materials according to the analysis results.

Ingot casting: up-drawing method, semi-continuous casting, horizontal continuous casting, iron mold casting, etc. Semi-continuous casting: It means that the molten water is downward, and the advantages and precision are the best. Up-drawing method: It means that the molten water is drawn upward, and the advantages and precision are better. Horizontal continuous casting: refers to the molten water is directly drawn out, cooled directly on the rolling mill, and rolled into coils, which has poor precision. Iron mold casting: refers to the molten water being poured directly into the iron mold, which has the worst precision.

Milling: Surface processing of the ingot.

Hot rolling: It means that the bad ingot is rolled after heating and before cooling, and no annealing is required.

Straightening-milling: The surface of the ingot is rough and the internal structure is loose.

Cold rolling: refers to the rolling of the billet while being annealed after heating and cooling.

Annealing: Bell furnace annealing is generally used for semi-finished products; annealing is uniform but controlled by thickness, and hardness is controlled by annealing time.

Pickling: Clean the dirt after annealing. Generally, pickling is required after annealing.

Fine (medium) rolling: The surface is very smooth and the internal structure is relatively uniform and compact.

Cleaning and leveling: determine the flatness of the board surface.

Slitting or cross-cutting: The C12300 Copper Strip Price for Sale China that needs to be slit is slit and reeled at this time, and the plate is subjected to cross-cutting at this time.

Inspection: Perform mechanical performance and chemical composition inspection.

Packing and warehousing: inspect the qualified products, mark and register them as required.
