摘要： A roll bending apparatus for use in a multi-stage rolling mill adapted for rolling a hard material or a thin sheet material with a high uniformity of thickness along the breadth, with a high degree of accuracy and low energy. The rolling mill has work rolls of a comparatively small diameter. The amount of bend of the small-diameter work roll is controlled by the roll bending apparatus for attaining the high degree of uniformity of thickness along the breadth of the rolled material. The roll bending apparatus has, for each of said work rolls, a supporting member having a work roll supporting portion for rotatably supporting the work roll and rockable vertically about a fulcrum, and a bending force generating means adapted for engaging the supporting member so as to cause a rocking motion of the supporting member thereby applying a substantially vertical roll bending force to the work roll through the supporting member.

摘要： The screwdown device has a position detector which is arranged inside a hydraulic piston. A cavity inside the piston accommodates a movable indicator rod and a stationary indicator head. The atmosphere around the position detector is thus protected by the hydraulic piston and by a hydraulic screwdown cylinder.

摘要： A continuous rolling mill has horizontal roll stands and vertical roll stands disposed alternatingly with rolling guides between the work rolls of adjacent roll stands. The roll stands together with the rolling guides are movable in the direction crossing the rolling line to an exchanging position where the work rolls and the rolling guides are exchanged with new ones. The continuous rolling mill further has a supporting frame supporting the roll stands and movable to the exchanging position thereby to bring the roll stands and rolling guides to the exchanging position, and an offsetting device adapted to move one of the adjacent roll stands relatively to the other of the adjacent roll stands and to the frame in the exchanging position such that the rolling lines of the adjacent roll stands may be offset from each other. This arrangement permits a reduction of the pitch or interval of the roll stands and affords a quick exchange of the rolls and rolling guides with new ones, contributing greatly to the reduction in installation space and cost while improving the efficiency of rate of operation of the rolling mill advantageously.

DE2605564A1 Flame cutting machine for continuous casting plant - using row of independently retractable rolls to support cast billet 未知

摘要： Flame cutting plant comprises a roller track for the continuous travel of the workpiece, a flame cutting machine which travels at the same speed as the workpiece once the latter has reached a specific position on the track and a slag catching well located beneath the track. The novelty is that the roller track uses several supporting rolls which are located on only one end of the roll in devices employed for the independent axial movement of each roll so they can be retracted sideways out of the slag well. Appts. is used for cutting a travelling billet during the continuous casting of metals. When the moving burner reaches a roll, the latter can be retracted so that is is not damaged by the burner, and the slag well prevents the accumulation of the slag arising during the cutting operation.
