Abstract

The research was focused on determining an optimum rolling emulsion to be used on a cold rolling mill from Galfinband Galati Romania. In this plant are obtained steel strips with the thickness of 0.7-0.8 mm. The main parameters depending on which the performance of a lubricant varies were determined. These were: viscosity, pH, thickness of lubrificant film, size of emulsion particles and their distribution on the surface of the steel band, oil content in the lubricating emulsion, usage degree of emulsion, applying method. The characteristics of mineral oil, fresh and recirculated emulsions have been analysed and discussed. Also by macroscopy were analyzed the form of contaminants on the surface of the steel bands which originate from lubricating emulsion. Their appearance is analyzed in the report with their generating processes and the quality of the emulsion.
