Abstract

PURPOSE:To improve the maintainability and operativity of the rolling mill, by arranging the principal part of mechanism for shifting the sleeve in outside front of the rolling stand. CONSTITUTION:If the hydraulic cylinders 13, 13', are actuated, an unillustrated supporting shaft is axially shifted; as a result, the sleeves 3, 3', are shifted in the direction of the roll axis to a preset distance through arms 6, 6', and guide rollers 7, 7'. If the hydraulic cylinders 13, 13', are against actuated, the supporting shaft is turned around through arms 19, 19', etc., and hereby, the arms 6, 6', and guide rollers 7, 7', are also turned around by a specified angle; according to circumstances, arms 6, 6', and guide rollers 7, 7', can be taken out of the window hole 22 of the rolling stand 5 as shown by the dotted line.
