Analysing metal working processes. G. Engberg, L. Karlsson, in Fundamentals of Metallurgy, 2005 Hot rolling. Mill data from the hot strip mill has been used to calculate the mean flow stress in each pass, assuming the material to be elastic ideally plastic. The roll force model used was a classical slab method with constant friction assumed in the roll gap.

The coilers pull the material through the mill, therefore the process is more similar to drawing than rolling. The material is fed back and forth through the mill until the desired thickness is reached, much like a reversing rolling mill. It is also used to process steel slabs into hot rolled coil. The Steckel mill allows the rolling of a large ...

Compact in design, CSP ® produces highquality hot strip in a single manufacturing line that combines casting, heating, and rolling. Our proven CSP ® caster with its patented funnelshaped mold casts thin slabs in thicknesses ranging from 50 to 90 mm. Next, the slabs go into the CSP ® furnace for temperature equalization. Straight after that, the CSP ® mill rolls them to final strip thickness.
