<p>PURPOSE:To prevent an oil pattern from being generated at a low cost without increasing the number of stages by measuring the temperature of a steel strip on the outlet side of a cold rolling mill and selecting such rolling conditions that the temperature does not generate oil patterns. CONSTITUTION:The temperature of the surface of a stainless steel strip 24 directly after rolling is found by empirical results so that irregular oil patterns are not generated on the surface of the stainless steel strip 24 subjected to annealing and pickling after cold rolling and the temperature of the surface of the steel strip directly after cold rolling is measured by a contact or non- contact type temperature system 34. Irregular oil patterns can be prevented from being generated on the surface of a stainless steel strip 24 by changing a cold draft, a rolling speed, an amount of rolling oil, and a rolling temperature, etc., so that the temperature comes below the temperature at which irregular oil patterns are generated.</p> |
