Select principle of foil pass processing rate

2015/10/9 15:57:38

Pass processing rate selection principle is as follows

1 In the device capability allows good rolling oil lubrication and cooling performance, and can get a good surface quality and flatness quality of the premise, should give full play to the plastic rolled metal, try using a large pass processing rate, improve production efficiency mill

2 Pass processing rate, to fully consider the mill performance, process lubrication, tension, raw roll rolling speed. Original state or semi-hard state aluminum billet rolling pass processing rate is generally 40% -65%, rolling passes hard state aluminum billet processing rate is generally 20% -40%

3 For thickness deviation, surface quality, flatness, high quality requirements of the product, should use a smaller pass processing rate.

4 Automatic control systems for thickness and flatness automatic control system of the mill may be appropriate to use a larger pass processing rate

5 Select pass processing rate from reality, in practice, on the basis of site equipment, quality, productivity, etc. after summary trial and error, finalized
