Application of Hot Rolling Lubrication on a Reversing Coil

In the early 1970s, roll lubrication for hot rolling was revisited by several scientists.2–4 The first experiment3 was performed on a laboratory mill by using cast rolls and mineral oil. When the 10% concentration of mineral oil was sprayed into the roll bite, the frictional coefficient was reduced by 25%. Surprisingly, the lubricant did not

Roll Bite Lubrication.

OVERVIEW Roll bite lubrication is used in over 80% of Flat Hot Strip Mills around the world. This process has been of interest for many years, and since the introduction of new developments in the hot mill environment and the increasing focus on cost savings and quality improvement, the advantages of hot mill lubrication have been underestimated.

Lubrication of hot-strip-mill rolls ScienceDirect

Feb 01, 1973 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.

WO2010096887A2 Process of production of manganese

Chemical process for the production of manganese sulfate (MnSO4) from the chemical reaction of the pirolusite (manganese bioxide MnO2) ore with gasses containing sulfur dioxide (SO2), through the direct reaction of the sulfur (gas) with the manganese bioxide (solid) for the production of manganese sulfate, enabling its later purification and adequacy to the commercial and industrial use.
