Embodiment Construction

[0017] The cross-fold defect shown by the tempering unit is not fully exposed after the annealing process. It appears between the uncoiler and the frame after the temper machine is uncoiled. Reduced, but not completely eliminated. Therefore, the analysis defects mainly occur between these two control points, the uncoiling steering roller and the tension roller.

[0018] The structure of a kind of cold-rolled strip leveling device embodiment is as figure 1 As shown, an uncoiling tension roller 2 and 3 are respectively arranged at the front and back of the machine of the device tempering machine 1, and an uncoiling steering roller 4 is also provided before the tension roller 3 in front of the machine along the strip advancing direction, as figure 2 As shown, the middle section of the two uncoiling tension rollers and the uncoiling turning roller body 5 is a cylindrical structure 52, and its two ends are respectively provided with a symmetrical inclined cone structure 52, and t...

Abstract

The invention relates to a cold-rolled strip steel flattening device and a cold-rolled strip steel cross break eliminating method. The front and back of a flattening machine are respectively provided with an uncoiling tension roller; an uncoiling turning roller is also arranged in front of the tension roller at the front of the flattening machine along the strip advancing direction; the middle sections of the bodies of the two uncoiling tension rollers and the uncoiling turning roller are in a cylindrical structure, and the two ends are in a symmetric slant cone-surface structure; and the gradient of the slant cone-surface structure is (1:100)-(1:30). As symmetric slant cone-surface structures are ground at the two ends of the bodies of the two uncoiling tension rollers at the front and back of the flattening machine and the uncoiling turning roller in front of the tension rollers, the non-uniform distribution of tangential force and normal force in the direction of the roller surface can be eliminated to a great degree, the tangential force and normal force in each direction of the roller surface are uniformly distributed in the area of the gradient of the slant cone-surface structure after the grinding, and the defect in quality of cross break can be eliminated to a great degree with the elimination rate of about 92%.

Description

technical field [0001] The invention relates to a flattening device for cold-rolled strip steel and a method for eliminating horizontal fold marks of cold-rolled strip steel. Background technique [0002] The existing cold-rolled steel plate production process is mainly: raw material hot-rolled coil→pickling→cold rolling-slitting-cleaning-annealing-finishing→finished product, and the finishing process is the last process, which determines the quality of the finished steel coil. inferior. Cross-fold defect is a common quality defect of cold-rolled strip steel in the leveling and straightening process. Generally, cross-fold defects are prone to occur when flattening strip steel with a thickness of less than 0.6mm. This defect generally occurs on both sides of the strip, and less in the middle. There are two manifestations of transverse folding defects: the first is the horizontal stripes at about 90° to the rolling direction, and the second is the nail-shaped arc stripes wit...
