Abstract

Thermogravimetry has been used to evaluate the residue and decomposition profile of rolling oil raw materials and system contaminants. The method described in this report simulates the interaction of the rolling oil with the steel surface during the annealing process, thereby offering insight into factors responsible for dirty burnoff and high surface carbon values. Typical rolling oil raw materials were evaluated, and the triglyceride component was found to be a major source of high surface carbon residue. Contaminants usually found in rolling oil systems were screened for residue characteristics. Several additives which promote low residue formation and clean burnoff were also discussed.
