By analyzing the drive torque of the cold strip mill,the author found out the relationship of the draught,rolling speed and main motor power,which is the reference of reformation to reasonably configure the rolling speed of single stand cold strip mill to increase output and decrease cos

In order to solve the problem of cold rolling strip surface wrinkles on the uncoiler,the stress distribution of a cold rolling strip on the uncoiler and its influencing factors were investigated by finite element method.

In order to further raise the cold rolling strip production efficiency and shorten annealing treatment time,the author analyzes the annealing process of hood type furnace and takes measures to optimize the annealing time,excess coefficient K and process atmosphere.
