HOT ROLLING MILL, HOT ROLLING MILL LINE, HOT ROLLING METHOD AND METHOD FOR MODERNIZING ROLLING MILL Russian patent published in 1999 - IPC

FIELD: hot rolling equipment. SUBSTANCE: rolling mill with crossing rolling rolls has backup rolls whose axes are not inclined in horizontal plane. Rolling roll axes may be inclined in horizontal plane relative to backup rolls in such a way that axes of rolling rolls are crossed with axes of backup rolls and axes of rolling roll are mutually crossed. Rolling mill is provided with apparatus for feeding lubricant into space between each rolling roll and each backup roll in order to significantly lower axial pressure acting upon rolling rolls. Lubricant feed is normalized that is why there is excellent possibility for controlling profile of rolled shapes. EFFECT: improved design of rolling mill, enhanced efficiency of method. 13 cl, 18 dwg
