<p>PURPOSE:To easily prevent a plate from camber by making a main adjustment of plate camber with an upper and a lower work roll different from each other in roughness and Young's modulus to adjust the inclined angles of a thin metallic plate on the inlet and outlet sides of a rolling mill to the horizontal surface and to make a fine adjustment of the plate warpage. CONSTITUTION:When the thin metallic plate having difference in roughness between a surface and a back face is rolled, many plates camber to the side of a work roll rough in roll roughness. This is because the elongation on the side large in roll roughness is smaller than the elongation on the side small in roll roughness. The Young's modulus large in roll roughness is made higher than the Young's modulus small in roll roughness to relieve an ununiform plastic deformation in a roll bite in the direction of the plate thickness. The flatteness of the roll by rolling load is larger in the work roll low in Young's modulus than in the work roll high in Young's modulus. When the thin metallic plate is inclined and rolled, for example, the pass line on the outlet side is moved upward, the material is wound upward. Thus, adjustment operation composed of main adjustment and fine adjustment of the plate camber is easy and most of the plate warpage can be removed.</p> |
