| 總結: | The purpose of this Thesis was to study the compensation condition for Gap between Work Roll in Hot Roll Steel Plate Production in order to control the thickness of Hot Steel Plate Product. The rolled steel plate of 7.7 mm. of thickness with and 5 feet of width was selected as a case study. The variable factors of the Force Last Pass and the Draft Last Pass were studied using Hot Rolling Simulation program. The wear crown for this study was assigned at 0.25, 0.15 and 0.05 mm. The relationship between Gap Trim and Force and Draft Last Pass were determined in order to adjust the thickness of Steel Plate via the experimental implementation. Pre-rolling steel was controlled at the Temp of 1180 °c. The result found that (1) Compensation Variation Thickness from this research could be used in Production Process and reduced the Thickness Defect down from 9.9% to 3.35%. (2) The result from experiment could control the thickness of Steel Plate and reduce thickness defect. |
