The analysis of two roll pass design options of ten roughing stands atOJSC "MMK" 370 rolling mill has been performed. The usage of a new form of the roll grooves will allow achieving higher durability of the rolls. Lesser rolls consumption will allow saving up to 800K rubles annually. More uniform load distribution by the stands will reduce the possibility of main mill lines equipment ...
mill is required. Pass Design The leader sections for the multiple slit rolling pro-cess, e.g. square, rectangular or round have to be of very close tolerance. This requires: * Correct pass profile in the rolls * Correct roll gap to ensure no overfill * Correct pass alignment between top and bottom rolls * Sound roll neck bearings and positive roll

Rolling of Steel in small and medium sized Rolling Mills. Rolling of steel consists of passing the material, usually termed as rolling stock, between two rolls driven at the same peripheral speed in opposite directions (i.e. one clockwise and the second anti-clockwise) and so spaced that the distance between them is somewhat less than the thickness of the steel section entering them.
Another solution for reducing the number of passes in the rolling mills is the employment of automated systems for Roll Pass Design as that proposed by Lambiase and Langella. ... Other shapes can be cold-rolled if the cross-section is relatively uniform and the transverse dimension is relatively small. ... A tandem mill is a special type of ...
Quad uses a scientific approach that includes developing a family tree that optimizes mill operation, reduces change time and minimizes roll inventory requirements. Simulation programs ensure the pass design will work within the limitations of the existing mill layout, mill stand & motor capabilities.
