Problems solved by technology
At present, because the position of the steering roller is determined after alignment, online adjustment is not allowed. In this way, when the number of steel belts increases, that is, when the looper trolley is far away from the correction roller, the steel belt will deviate on the steering roller, which is easy Cause scraping accidents, the steel strip will be scraped off in severe cases

Embodiment Construction
[0013] Embodiments of the present invention will be further described below in conjunction with specific drawings:
[0014] See figure 1 , figure 2 , in order to make the bearing seat easy to adjust, on both sides of the bearing seat (the far end side where the steering roller is in contact with the steel belt and the near end side where the steering roller is not in contact with the steel belt), the four fastening bolts of the bearing seat 2 Loosen, and then adjust the distal bolt 1 and the proximal bolt 3, so that the bearing seat can move.
[0015] The invention discloses a method for adjusting the deviation of the strip steel on the steering roller of the looper trolley on the continuous withdrawal line, so that the deflection angle of the axis of the upper steering roller and the axis of the middle steering roller on the horizontal plane relative to the roller axis of the deviation correcting roller can be adjusted online. The specific implementation steps as follows: ...

The invention relates to the field of cold-rolled silicon steel continuous annealing production, in particular to a method for regulating line deflection of strip steel on a continuous annealing loop trolley turning roll. The method is characterized in that the deflection angles, relative to the axis of a rectifying roll on the horizontal plane, of the axis of an upper turning roll and the axis of a middle turning roll can be regulated on line. The method comprises the steps that (1) the position bases of bearing blocks at the two ends of each turning roll are marked; (2) four fasten bolts of the bearing block at the small circle end of each turning roll are released, and two near-end bolts are regulated to abut against each bearing block in an extruded mode, so that the strip steel moves towards the axis on each turning roll; (3) the bearing block on the small circle side of each turning roll is regulated to the extreme position, the near-end bolts and far-end bolts on the two sides of each bearing block are tightly pushed, two far-end bolts, located on the contact side of the corresponding turning roll and the strip steel, of each bearing block are regulated to abut against the corresponding bearing block in an extruded mode, and therefore each bearing block moves towards the direction of the corresponding near-end bolt. Compared with the prior art, the method has the advantages that when the surfaces of the turning rolls change, on-line regulation can be performed timely, and strip steel scraping accidents are reduced.
Description
technical field [0001] The invention relates to the field of a continuous annealing production line for cold-rolled silicon steel, in particular to a method for adjusting deviation of strip steel on a steering roller of a looper trolley in a continuous annealing line. Background technique [0002] The cold-rolled silicon steel continuous annealing production line is equipped with an inlet looper and an outlet looper respectively, and each of the two loopers has a looper trolley equipped with three turning rollers, see figure 1 , the turning rollers are divided into upper turning rollers (4), middle turning rollers (5) and lower turning rollers (6) from top to bottom, and three upper and lower layers of correcting rollers are arranged opposite to the three turning rollers, namely the upper turning rollers ( 7), middle deflection roller (8) and lower deflection roller (9). There are six layers of twists and turns inside. After the steering roller has been working for a long t...
