Abstract

The invention relates to an uncoiling section method of a cold continuous rolling unit, in particular to a deviation-rectification-free uncoiling device and method of the cold continuous rolling unit. The device is characterized by at least comprising a tape head uncoiling mechanism and a tape tail uncoiling mechanism, wherein the tape head uncoiling mechanism and the tape tail uncoiling mechanism pass through a second turning roll and a horizontal roll table and then enter into a welding machine. The invention provides the deviation-rectification-free uncoiling device which is simple in structure and low in manufacturing cost and the deviation-rectification-free uncoiling method so as to overcome the defects in the prior art.

Description

technical field [0001] The invention relates to a method for uncoiling section of a cold tandem rolling mill, in particular to a method for uncoiling without deviation correction of a cold tandem rolling mill. Background technique [0002] The existing uncoiling section technology of the tandem cold rolling mill is a floating uncoiler with no positioning push plate and the uncoiling CPC, which performs floating centering during the uncoiling process except for the leading and tailings. The problem with this method is that the structure of the uncoiler is complicated and the manufacturing cost is high. [0003] The working principle of the existing technology is to use the winding trolley to manually rewind (manually control the lifting height of the trolley and the horizontal parking position). When the leader passes the horizontal track, the leader is manually centered. The measuring head cooperates to realize the floating centering of the uncoiling strip, and the centerin...
