In corresponding with profile shape defect trouble about 1.2 mm x (250 ~ 380) mm strip of 301S and 301B cold rolled austenite stainless steel at steel works

the influence of change of strip width on profile shape during twelve-high mill rolling process (reduction 18% -26%

rolling force 750 ~ 1 600 kN) is obtained by analysis on a vast amount practical production data. Results show that as the width of strip is larger

with increasing rolling force or shifting intermediate rolls along axial direction to median

the central buckling profile shape defect decreases ； and as width of strip is smaller

with decreasing rolling force or shifting intermediate rolls along axial direction to both sides

the both-side edge buckling profile shape defect shall be reduced.
