COMPOSITE ROLL Russian patent published in 2002 - IPC

FIELD: manufacture of rolled products. SUBSTANCE: composite roll has carrier profiled spindle with rib and band provided with profiled internal surface and put in tension state for free displacement of its smaller diameter parts in heated state along carrier spindle through greater diameter parts along its length toward rib. Setting surfaces of spindle and band are made profiled in accordance with dependence: y=Δ(x/L)ⁿ, where y is profile ordinate, mm; Δ - is alteration of band internal diameter upon heating, mm; x=0...L is current ordinate of profile along roll barrel, mm; L is length of roll barrel, mm; n=L/D, where D is diameter of spindle, mm. EFFECT: increased service life of roll due to reduced probability of partial axial slipping-down of band from spindle. 2 dwg
