Title:
金属材料の圧延のための圧延スタンド
Document Type and Number:
Japanese Patent JP7227388
Kind Code:
B2
Abstract:
A rolling mill for rolling metal products, comprising two roller stands with a stand cross-member. A roller is rotatably mounted in the roller stands. The roller is operatively connected to a balancing cross-member, and at least one hydraulic piston-cylinder system is arranged in the stand cross-member, with which a tensile force can be generated between the stand cross-member and the balancing cross-member by the hydraulic piston-cylinder system. In order to prevent leakages in particular in the event of tall mill ascending paths, the piston-cylinder system has a cylinder housing with an upper axial end and a lower axial end. A piston is movably arranged in the cylinder housing, and the piston protrudes beyond the cylinder housing both at the upper axial end as well as at the lower axial end in each operating state.
