Abstract

The invention provides a bowed roll block fast replacing device for a rolling mill, which at least comprises a bowed roll block replacing trolley, a lifting platform and a jack, wherein the lifting platform is arranged above the bowed roll block replacing trolley and can make vertical movement relative to the bowed roll block replacing trolley; and the jack is arranged between the bowed roll block replacing trolley and the lifting platform and is used for controlling the lifting platform to ascend or descend. The bowed roll block fast replacing device for a rolling mill has simple structure, is convenient to operate, can realize the fast disassembly or assembly of bowed roll blocks of the rolling mill, greatly improves the operating efficiency, greatly lowers the labor intensity and shortens the equipment maintenance time.

Description

technical field [0001] The invention relates to a rolling mill bending block replacement device, in particular to a rolling mill bending block quick replacement device which can quickly replace the rolling mill bending block and improve production efficiency. Background technique [0002] At present, in order to improve rolling quality in strip rolling mills, roll bending devices are usually arranged at both ends of the work rolls of the rolling mill. For example, the Chinese patent No. "200820114799.9" discloses a "rolling mill work roll positive / negative roll bending device". Matched four downbending roller blocks. The plate shape is adjusted through the roll bending device, which ensures the positive or negative bending function of the work rolls, realizes the control of the plate shape during the rolling process, and improves the quality of the plate shape. [0003] During the use of the rolling mill, due to the wear and tear of the bending block and the replacement of...
