CLUSTER ROLLING STAND Russian patent published in 1998 - IPC

FIELD: rolled stock production. SUBSTANCE: cluster rolling stand includes at least one rolling roll mounted at one side of rolling line, at least one intermediate roll and at least one set of backup rollers. Said roller set consists of several backup rollers mounted on shaft practically parallel relative to lengthwise axis of said rolling and intermediate rolls and several seat inserts supporting said set of rollers in housing. It is possible to adjust position of seat inserts (independently one from another) relative to axis of rolling roll for bending said roll by means of regulation mechanisms. Said mechanisms providing smooth regulation of roll gap due to bending rolling rolls at rolling process are in the form of pressure members acting directly upon corresponding seat inserts and having piezoelectric semiconductor components. EFFECT: improved design. 8 cl, 4 dwg
