John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 3.5 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).

Consider the hot rolling of a low-carbon steel strip in a single stand roughing mill. Let the entry thickness of the slab be 20 mm and its width to be 2000 mm. Its resistance to deformation is taken to be 150 MPa. It is reduced by 30% using work rolls of 800 mm diameter, rotating at 50 rpm.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight. Read More

In our country, there are three rolls single stand, two rolls or four rolls rough rolling, and four rolls double stand. The 2300mm Laut plate mill in our country is mostly a single stand. When rolling, the roll bears greater rolling pressure and thermal impact and requires higher heat resistance, wear-resistance, and strength.

after the roughing mill stand of a hot strip mill has b een discussed. The control The control technology developed is based on both model techniques (level 2 a utomation) and real-

To determine the amount of roll gap adjustment, we propose a model for equivalent roll gap decrement which reduces the increased exit cross sectional area due to wear. We applied the proposed model to multi-stand rolling (roughing train of POSCO No. 2 Rod Mill) as well as single-stand reversible rolling.

According to the status of rolling middling stock without crown control on the single rough stand in semi-continuous hot strip rolling in domestic, the advantages and the working mode of middle plate rolling with proportional crown are introduced. Finally, the ways to improve the existing rough mill with CVC technology are discussed.

28. Work roll latches • In the closed position, the latches are connecting the Work roll chocks with the CVC-shifting cylinder. In roll change the latches must be opened so that the work rolls (WR) can be removed from the mill stand. The top and bottom latches are driven by …

For the roughing mill (reversible 4-high) both roll force and roll torque were available so the friction coefficient could be evaluated in addition to the flow stress for each pass. The values were close to 0.3 so it was decided to use this for all calculations, also for the finishing, six-stand (4-high), tandem mill.
