摘　　要：论述了中厚板矫直过程中影响板材矫直的关键因素,根据金属材料弹塑性弯曲理论和矫直原理推导出矫直辊径计算公式。采用该公式验证了5.5m和4.3m中厚板生产线冷矫机辊径与钢板屈服强度间的关系,分析了该冷矫机所能矫平最薄钢板的厚度,计算结果与实际吻合。Roll diameter formula of cold leveler was derived based on plastoelastic deformation theory andstraightening theory. Meanwhile, the key factors of plate straightening process on medium and heavy plat werediscussed in this paper. The formula was used in cold levelers of 5.5m and 4. 3m heavy plate production line.The thinnest thickness of the plate straightened for the cold leveler was analyzed. The calculated results agreedwith the actual production. The formula of roll diameter calculation for cold leveler has guiding significance forroller diameter designing of leveler and production organizing.
