中板轧制过程板坯弯曲生成与抑制之三——温差、压下率对板坯弯曲的影响

Forming and Curbing of Plate Bending in Jobbing Sheet Rolling Process (3)——Pass reduction and temperature difference effecting plate bending

摘要: 研究了在中板轧制过程中抑制板坯弯曲的措施之一.从理论上建立了道次压下率大小和板坯断面温差与板坯弯曲的关系,从而给出抑制板坯弯曲时道次压下率最佳值的确定原则.其正确性已被实践所证明.

Abstract: One of the method of curbing plate bending in jobbing sheet rolling process was researched. The relationship between plate bending curvature and pass reduction and temperature difference of plate section is analyzed. The optimum value of pass reduction can be decided.The theory has been adopted in practical production and is proved to be correct.
