Hot Strip Mill and Cold Rolling Mill Industry ...

2021-7-21  With hot rolling, heated metal goes through a rolling machine where it is worked into a sheet or bar. With cold rolling, sheet steel is made thinner at normal temperatures, and its surface is made smooth and uniform. Tsubaki products are used in both hot and cold rolling.

2021-7-21  Molten steel refined in the converter is solidified in this process to produce billets of a given shape. The molten steel discharged from the converter is continuously poured with a ladle into a mold below for cooling. After the steel is cooled and solidified, it is cut to a given length before it is conveyed to the rolling process for shaping.

Development and application of roll contour configuration ...

2018-6-29  In order to improve the flatness of hot rolled thin gauge steel strip, a new type of roll contour configuration was developed for a four-high temper rolling mill based on the finite element method analysis. The roll contour configuration consists of a variable contact back-up roll contour and a positive crown work roll contour.

Rolling Process: Working, Application, Defects, Type of ...

In this type of mill, the rollers are both adjustable. In these mills, rotation of that two rolls is made in two different directions. In this operation, the metal is passed between two rollers that rotate at the same speed but it is in the opposite direction. It is used in slabbing, plumbing, rail, plate roughing work and many other areas.
