Calculating Power Parameters of Rolling Mill ProQuest
The combination of rolling in stands with multi-roll gauge and drawing is a promising direction in the production of wire from difficult-to-form steels and alloys. Digital models for pressure-based metal treatment are also necessary for calculating the rolling-mill power parameters during the development of new assortments at the operating mills.

2015-11-27 If a mill rolls 80 % of the calendar year, that is 365 x 24 x 0.80 = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x 0.81 = 7096.6, creating 87.6 extra rolling hours.

ROLLING-(A Brief Guide To Rolling And Rolling Mills)
Rolling is the process of plastically deforming metal by passing it between the roles. The rolling process is basically used for reducing the cross-sectional area of the metal stock. (The width is the same but there is a significant reduction of thickness). It is the most widely used forming process and it provides high production with very
