- Abstract
Rational reduction and tension schedules and roll profiles for 150/500×400 four-high reversing mill and 350×450 two-high reversing mill were developed and studied to increase the output of strips of high accuracy. For the 150/500×400 mill, increasing the work roll crown from +0.1 to +0.15 mm, the specific back tension from 0.12-0.16 to 0.14-0.18 МРа, and the specific front tension from 0.16-0.18 to 0.18-0.20 MPa appeared to decrease the transverse thickness deviation of strips by 10% compared with the conventional reduction and tension schedules. For the 350×450 mill, increasing the work roll crown from +(0.04-0.07) to +0.09 mm, the specific back tension from 3.3 to 8.7 MPa, and the specific front tension from 4.44 to 10.0 МРа appeared to decrease the transverse thickness deviation of 1-mm strips to 0.039 mm, which may be considered high accuracy. A mathematical model is proposed to analyze the stress-strain state of wavy strips with allowance for hardening. The numerical modeling showed that the tangential stresses are maximum on the upper and lower faces of a 0.5h strip, while the radial stresses are maximum in the neutral plane of the strip.
