1. C12200 Copper Sheet for Sale ingredients: according to the requirements of different grades of alloy element composition

2. Smelting (At the same time, pre-furnace analysis is required: chemical analysis and optical analysis)

3. Ingot casting (up-drawing method, semi-continuous casting, horizontal continuous casting, iron mold casting)

a. Semi-continuous casting: it means that the molten water is downward and the precision is good

b. Leading method: refers to the molten water is drawn upwards, with better precision

c. Horizontal continuous casting: refers to the molten water is directly drawn out, cooled directly on the rolling mill, rolled into coils, and the precision is not good

d. Iron mold casting: refers to the molten water is poured directly into the iron mold, with poor precision

4. Ingot casting: flat, round, block

5. Milling (surface treatment of ingots)

6. Heating

7. Hot rolling: it means that the bad ingot is rolled after heating and before cooling, without annealing

8. Straightening-milling (R product, rough surface, loose internal structure, the current state is soft)

9. Cold rolling: refers to the heating and cooling of the billet, and rolling while annealing

10. Annealing: Bell furnace annealing (semi-finished products)

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

12. Fine (medium) rolling (multiple steps) (the surface is very smooth, the internal structure is more uniform and compact)

13. Cleaning (Product Y) Finished Annealing (Product M, Y2)

a. Bell jar furnace annealing: the annealing is uniform, but it is controlled by the thickness, and the hardness is controlled by the annealing time

b. Air cushion furnace annealing: the annealing is not uniform, but it is not controlled by the thickness, and the hardness is controlled by the transmission speed

14. Leveling: Determine the flatness of the board surface

15.Slitting or cross-cutting: the copper strip that needs to be slit is slit and reeled at this time, and the plate is subjected to cross-cutting at this time

16. Inspection

17. Packing and warehousing
