摘要： PURPOSE: To facilitate installing and removing work for a guide trough of a rolling mill by attaching a cover assembly so that a roll stand is adjustably moved to an open position so as to allow access to work rolls or to a guide position where a trough is aligned witch a rolling line. CONSTITUTION: When existing in a closed position, a cover assembly 20 is placed on a parallel support flange 28 forming a part of a roll stand 10. The cover assembly 20 in the closed position cooperates with the lower side roll stand 10 to confine work rolls in the enclosing space 30, and workers are protected from a cobble related accident. Also, when access to the work rolls is necessitated, the cover assembly 20 is rocked upward up to a complete open position by exciting a rotational actuator 22. And a guide trough 24 is integrally incorporated into the cover assembly 20 rotationally adjustable to the rolling line, and whereby the guide trough is easily arranged.

摘要： PURPOSE:To eliminate the remaining of an excess metal quantity after cross helical rolling and to efficiently flatten a web part overt the entire width by providing excess metals to the web part near flanges by intermediate rolling and adjusting the same to a prescribed expansion quantity by intermediate rolling or finish rolling. CONSTITUTION:The excess metals A are provided to the web W near the flanges F of a material S supplied to a cross helical rolling mill 11 and are adjusted to the excess metal quantity corresponding to the prescribed expansion quantity by an intermediate rolling mill 3 or finishing mill 5 disposed on the upper stream of the cross helical rolling mill 11. The web W part of the shapes on the outlet side of cross helical rolls 11 is flattened over the entire width thereof if the excess metal parts A are rolled down to the thickness equal to the thickness of the unrolled down web W part by the cross helical rolling mill 11. The shaping rolling in succession thereto is thus merely required to correct only the strain of the sectional shape, for which an extremely simple device is necessitated.
