中板轧制过程板坯弯曲生成与抑制之二——采用上压法抑制板坯弯曲

Forming and Curbing of Plate Bending in Jobbing Sheet Rolling Process(2)——Curbing Plate Bending with Smaller Lower Working roll

摘要: 研究在中板轧制过程中抑制板坯弯曲的措施.在国内外首次应用上压法轧制来抑制中板轧制过程中板坯生成的弯曲现象,从理论上建立了板坯上下表面温差与轧辊辊径差的关系,为现场提供配辊原则.

Abstract: One kind of the method of curbing plate bending in jobbing sheet rolling process has been researched. For the first time,the method of using smaller lower working roll is put forward with formula and practical data for curbing plate bending caused by temperature difference in the section of plate. So, the choice of rolls diameter can be guided in practical production.
