Hot Strip Mill

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)

Rolling mills

Rolling mills are also classified on the basis of their technological processes as casting and rolling units mills for the reduction of ingots (including slab and blooming mills) reversing single-stand mills tandem mills multistand mills continuous mills and cold-rolling mills The size classification of a rolling mill designed for rolling sheets or bands is determined by the roll body

Sleeve

In a typical conventional three roll mill as the cane blanket moves through the mill part of the extracted juice comes out on the top of the cane blanket and drains under the action of gravity to collection chutes at the ends of the top roll However part of the juice which gets extracted remains pressurized in the cane blanket till the cane blanket comes out of the final nip of the

Analysis of Small Spalling Mechanism on Hot Rolling Mill

rolling mill high speed steel roll an actual hot rolling mill roll was investigated and the thermal cycle and Mode II fatigue crack growth tests which reflect the results of the investigation were carried out From the investigation of the actual hot rolling mill roll it was proven that the small spalling was generated by heat crack initiation by thermal cycling and Mode II fatigue crack

DESIGN AND ANALYSIS OF AXIAL CROSSING OF WORK ROLLS IN

For a mill to roll any product to an accurate shape and size the alignment of the rolls and the roll gap must be precisely maintained Wear on the mating surfaces of the roll chocks liner and mill housings liner can cause excessive clearance between the two parts which can cause axis crossing of roll resulting Loss of gauge control Loss of shape reduced speed and ultimately result in loss

Rolling mill

The number and arrangement of the roll stands of a rolling mill are determined by the function of the mill the number of times the metal must pass between the rolls to produce a given section and the assigned output Eight types of rolling mills are distinguished on this basis Single-stand mills include most blooming mills slab mills ball-rolling mills and mills for the cold rolling of

K K Singh et al Detection of Defects on Cold Rolling

K K Singh et al Detection of Defects on Cold Rolling Mill ABSTRACT The service induced defects in CRM rolls due to them being subjected to complex mechanical and thermal stresses in cold rolling of steel strips or coils if not removed completely during roll grinding become primarily responsible for roll spalling The high instances of roll spalling lead to increased specific roll
