【Abstract】 Based on the rolling force and power data sampled on line,the method of estimating the ten-sion for continuous small bar mill was studied.It was shown that the electric current-torque me-thod is useful to estimate tension on line for continuous small bar mill by DMDD.Uniform andhigher temperature of workpiece is favourable to realizing the countinuous rolling with no tensionand improving the stability of rolling process.Based on the tension cstimation,the torque andpower model for No.5 steel angles continuous rolling with no tension have been established.更多还原
