Lunn bar, fitted parallel to the mill rolls and positioned so that the operator works over it. The Lunn bar has proved effective in reducing the number of fata l and serious maiming injuries at two roll mills from their historical level of about 20 per year in the 1950s - 60s,
G. Engberg, L. Karlsson, in Fundamentals of Metallurgy, 2005 11.5.1 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. For the roughing mill reversible 4-high both roll force ...
2. Reduction roller mill rolls are straight roller mill rolls. The task of reduction roller is gradually to convert semolina obtained in the crushing system into the flour and to make flake by crushing bran and germ particles. They make the compress, crushing and shredding tasks. Expansion occurs at the edges because of heat released due to ...
Sendzimir Mill or Z-Mill is a machine for cold rolling for stainless steel. This 20-high mill configuration utilizes cascaded supporting rolls to apply force on the small work rolls in the center. This roll setup exerts extremely high forces through the work roll and yet keeps the work roll from flexing.
