The cause should be found, to determine if the rolls were set up improperly or there was a possible mill problem. Uneven wear can be caused by a design flaw that did not take into account the type of material to be formed or maximum gauge thickness. Roll bores and faces that are worn beyond normal limits can indicate shaft problems or, again ...

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.

mostly consumed, and the roll shafts are used more than once. With roll shafts being re-used 3-5 times, the coefficient of material consumption for sleeved rolls is 2-5 times as low as for solid forged rolls. A built-up (sleeved) roll consists of a steel shaft and a sleeve.
May 05, 2019· Roll forming operation : MATERIAL. One of the main parameters that define the success of a roll forming operation is the character of the material. for design the optimal process, the designer should provide material information to use prior to the tooling designing such as material mechanical property ranges, gauge tolerances and shape tolerances, different metallic coatings.
