Example Embodiment
[0051] Example one:
[0052] A stainless steel coil with a thickness of 0.08mm and a width of 650mm is selected as the raw material, and the thickness of the finished steel strip for rolling is 0.02mm.
[0053] First, a 20-high rolling mill with a thickness of 0.08mm as a raw material for cold-rolled coils is rolled. When rolling, the British BP rolling oil is used for lubrication and cooling. The temperature of the rolling oil is 39°C. After 8 passes, it is cold rolled to 0.02mm. The rolling speed of the first seven passes is 300m / min, the rolling speed of the finished product pass is 200m / min, the work roll diameter is 27mm, the rolling pressure during the whole process is 1100-1300KN, and the reduction rate of the pass is 10-30%.
[0054] The roll system configuration selects the designed roll system (that is, the roll system equipped in the above-mentioned roll system configuration method).
[0055] The main technical indicators of products produced by the above process can reach:...
Example Embodiment
[0059] Embodiment two:
[0060] A stainless steel coil with a thickness of 0.1mm and a width of 650mm is selected as the raw material, and the thickness of the finished steel strip for rolling is 0.03mm.
[0061] First, a 20-high rolling mill with a thickness of 0.1mm as a raw material for cold-rolled coils is rolled. During rolling, British BP rolling oil is used for lubrication and cooling. The temperature of the rolling oil is 40°C. After 8 passes, it is cold rolled to 0.03mm. The rolling speed of the first seven passes is 350m / min, the rolling speed of the finished product pass is 200m / min, the work roll diameter is 28mm, the rolling pressure during the whole process is 1000-1200KN, and the pass reduction rate is 10-30%.
[0062] The roll system configuration selects the designed roll system.
[0063] The main technical indicators of products produced by the above process can reach:
[0064] 1) Thickness deviation: 0.03±0.002mm;
[0065] 2) Hardness (HV): 560—590HV;
[0066] 3) Rough...
