| Description |
Though the field trials are the ultimate in selection of hot
rolling lubricants which.are very expensive and time
consuming. The conventional laboratory tests on Timken, 4-
ball wear! e.p. testing machine do not predict the behavior
of lubricants clearly required for hot rolling mill.
The hot rolling! metalworking process involves generation of
fresh virgin surfaces which ar€ highly reactive in nature
alongwith heat of deformation. They aggravate the
lubrication conditions prevailing in the contact zone.
Therefore, a laboratory method is required for evaluation of
load carrying capacity of oils.
A laboratory test method was devised on a high speed disc
machine using a pair of hard alloy and mild steel discs
rotating over each other in circumferential contact. The
lubricant rating was characterised by the load at which the
frictional torque jumps to very high level. The lubricant
rating correlated well with the laboratory rolling mill. The
paper describes the method and compares the results with
laboratory rolling mill.
