Lubrication of hot-strip-mill rolls - ScienceDirect
LUBRICATION OF HOT-STRIP-MILL ROLLS 205 To avoid problems with front-end entry the oil was switched on by a signal from the main-drive motor load and switched off before the tail end had passed through the mill by similar means. In this way time was allowed for the oil to "burn on" the rolls before the next slab was ready for processing. The average quantity of oil applied was 60 grammes per ...

Rolling of steel in Hot Strip Mill – IspatGuru
Hot strip mills in these days are either conventional hot strip mills or strip mills for rolling thin slabs. The primary function of the conventional hot strip mill (HSM) is to reheat the semi-finished steel slabs (rolled or continuously cast) to the rolling temperatures and then to roll them thinner and longer through a series of rolling mill stands driven by large motors and finally coiling ...

Rolling (metalworking) - Wikipedia
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.
