Abstract

The invention belongs to the technical field of metal material machining, and discloses a strip head straightening method. Strip head straightening is realized through a feeding roller and a steeringroller of a rolling mill. The strip head straightening method includes the steps that firstly, a steel coil is upwardly rolled to a reel mandrel of the rolling mill; secondly, the reel mandrel is rotated in the clockwise direction, uncoiling is carried out and the steel coil strip head is sent to the upper part of the steering roller, and the feeding roller is lowered to press the strip head; thirdly, the feeding roller is rotated in the counterclockwise direction, meanwhile the reel mandrel is rotated clockwise to drive uncoiled strip steel to upwardly arch; and fourthly, the reel mandrel isrotated counterclockwise to drive the uncoiled strip steel to retreat, and the warping height of the strip head is adjusted to 20-40mm through strip head clamping of the feeding roller and the steering roller. According to the strip head straightening method, strip head straightening and strip penetrating can be realized based on the structure of the rolling mill, additional straightening equipment is avoided, thus on the one hand, the equipment size is simplified, and meanwhile lowing of the production efficiency due to the straightening equipment is also avoided.

Description

technical field [0001] The invention relates to the technical field of metal material processing, in particular to a belt head straightening method. Background technique [0002] The single-stand reversing rolling mill uncoiler is used to uncoil the strip along the strip head and send it to the rolling mill for rolling, and provide the post tension of the first rolling pass, which is the key equipment to ensure rolling stability. Before the coil head passes through the roll gap of the rolling mill, it is necessary to use specific straightening equipment to straighten the strip head to a certain height, so that the strip head can pass through the roll gap of the rolling mill smoothly and complete the strip threading process. When using the coiler of the reversing rolling mill for rolling, it is necessary to set up special equipment for strip head straightening at the entrance and exit positions, such as three-roll leveling machines, etc. The operation process of this type of ...
