J. Cent. South Univ. Technol. (2010) 17: 1000-1005 DOI: 10.1007/s11771-010-0590-5 Improved model to SOLVE influence coefficients of work roll deflection ZHAO Tie-yong(赵铁勇), XIAO Hong(肖宏... was regarded as a cantilever beam and new influence coefficients were deduced. The effect of the bending force was taken into account independently. Therefore, the contribution to work roll deflection caused......
; Abstract: The deflection of rolls of Sendzimir mill with double AS-U-Roll was simulated by finite element method(FEM). The influences of rolling pressure, strip width and rolls-assignment on rolls deflection were analyzed. The results show that the work roll deflection increases......
deformation of cold strip mill was derived by the influence function method according to the deflection concordance principle between the roll sleeve and roll mandrel and working roll and the force... of cross sliding is 100 mm. Moreover, the influences of the bending force and cross sliding value of work roll on the deflection of composite back-up roll are not more than 0.7 μm/(10×104 N) and 0.8 μm/100......
