SHEET ROOLING MILL STAND ROLL, FOUR- AND SIX-ROLL STANDS AND CONTINUOUS SET OF FOUR- AND/OR SIX-ROLL STANDS |
摘要 |
FIELD: metallurgy.SUBSTANCE: invention relates to sheet rolling in ferrous and nonferrous metallurgy. Sheet rolling mill stand roll features body shaped to one-sheet hyperboloid. Four-roll rolling stand has support rolls shaped to one-sheet hyperboloid. Note here that lengthwise axes of working rolls are crossed in horizontal plane parallel with rectilinear generating lines of body surface in contact with support rolls. Six-roll rolling stand support and working roll axes are crossed in horizontal plane while idle rolls are shaped to one-sheet hyperboloid. Note here that cross angle and direction of turn of lengthwise axes of support and working rolls are interrelated. In continuous set of four- and/or six-roll stands lengthwise axes of working rolls are crossed. Note here that maximum crossing angle relates to the first stands of the group while minimum angle is inherent in the last stands. Working roll pads feature curvilinear surface of side faces, their radius of curvature being equal to maximum radius of working rolls of this stand. Said side faces contact with supports connected with hydraulic cylinder rods arranged in plates secured at bed sidewalls to displace vertically thereat.EFFECT: possibility to perfect the rolled stock cross-section.9 cl, 13 dwg |
