Hot Rolling of Strip with Lubricant: Theoretical and Practical Aspects

Resumo

The use of lubricant in the hot rolling of steel strip by means of broad-strip mills is considered, in theoretical and practical terms. The benefits of the lubricant are shown. Throlle delivery of lubricant to the deformation zone is analyzed. Practical methods of supplying lubricants to the rolls and the deformation zone are assessed. Recommendations are made regarding lubricant selection. Methods are proposed for calculating the lubricant flow rate in hot strip rolling.
