Rolling Oils for Cold Reduction

THE AUTHOR commenced his working life in the Cold‐Rolling Industry in the 1930's at a time when the industry demanded that a boy should serve an apprenticeship. Roll changing was very rare indeed in those days and if a wider section were the “follow‐on” order, this meant an hour or more of roll scouring using a shaped stick and powdered emery. This procedure terminated with improved production techniques but this old practice certainly taught the Roller what the job was all about, for example, when a particular shape of strip was undesirable, the Roller could put his finger on the cause and the remedy.
