Single-stand reversible rolling process for ultrathin wide red copper belt

[0030] A single-stand reversible rolling process of an ultra-thin wide-width red copper strip provided by the invention comprises specific steps as follows:

[0031] S1, put the red copper raw material into the intermediate frequency furnace for melting until it reaches a liquid state, and the melting temperature is 1150°C;

[0032] S2, the obtained smelting liquid is formed into a slab with a certain cross-sectional shape and a certain size specification through the continuous casting machine, and is cooled by water until the slab drops to 20°C;

[0033] S3, putting the billet into the forging press for forging and pressing to obtain a red copper sheet, wherein the thickness of the red copper sheet is 2cm;

[0034] S4, putting the red copper sheet into water, and cleaning the red copper sheet, after cleaning, drying the red copper sheet by drying equipment;

[0035] S5, putting the red copper sheet into a vacuum annealing furnace for annealing, the annealing temperature is 510°
