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

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.
