Research on Control Measures for Tight Rib Loose Defects on Edge of 3102 Alloy Air Conditioning Foil Rolled by CVC Six Roll Cold Rolling Mill
The edge tightening of 3102 alloy air conditioning foil rolled by 2300mm CVC six-high cold rolling mill is analyzed in this paper.The main reasons are large heat dissipation at roll edge and uneven thermal crown,which leads to the edge tightening and loose rib defects.By adjusting the input width,increasing the coverage of the measuring ring of the profile roll,adjusting the front and back tension,and increasing the target curve coefficients of C4 and A16 profile,the defects of tight edge and loose rib are effectively improved,and the fission width is controlled from 10mm to less than 5mm,which improved the yield of air conditioning foil blank.
