Abstract
The utility model discloses a coiling steering roller system for controlling crease mark on the head of hot-rolled strip steel, which belongs to the field of steel production, and comprises a steering roller and compression rollers, wherein the compression rollers comprise a front compression roller and a rear compression roller, the diameter of the steering roller is 500mm, and the diameters of the two compression rollers are 200 mm; when the front pressing roller and the rear pressing roller are pressed down, the front pressing roller and the rear pressing roller are symmetrically distributed by taking the vertical central line of the steering roller as an axis, the included angle between the front pressing roller and the rear pressing roller is 55 degrees, and the roller bodies of the steering roller and the two pressing rollers are vertical to the central line of the unit. Compared with the prior art have work efficiency height, be applicable to the characteristics of continuous production line.
Description
Technical Field
The utility model relates to a steel production facility, especially a roll system and application method suitable for take steel head crease seal control in coiling processes such as hot rolling belted steel pickling line, hot rolling belted steel levelling line, the continuous galvanizing line of hot base belted steel, improve crease seal degree and shorten and copy length (number of turns).
Background
The thickness of the hot-base strip steel is thicker than that of the cold-rolled strip steel, and the performance of the hot-base strip steel is different from that of the cold-rolled strip steel, so that the strip steel is easily subjected to the defect of crease mark of an inner ring under the influence of a strip head and influences the use of customers in the process of recoiling in subsequent treatment processes (pickling, leveling, galvanizing and longitudinal cutting).
At present, two methods are mainly used for solving the crease mark of the head of the strip steel, firstly, a curling mandrel with a jaw is adopted, the crease mark can be completely eliminated, but the strip head needs to be accurately inserted into the jaw, the rhythm is slow, the efficiency is low, and therefore, the method is not suitable for a continuous production line and is mostly used in a discontinuous production line such as a longitudinal cutting line. The other method adopts a positioning sleeve scheme, so that the crease can be completely eliminated under the condition of accurate positioning, a special sleeve is required in the method, and the positioning success rate is not high.
SUMMERY OF THE UTILITY MODEL
The technical task of the utility model is to provide a control hot rolling belted steel head crease mark batches steering roll system to the not enough of above prior art. By optimizing the arrangement of the threading steering roller and the compression roller and the size of the roller diameter, the defect of head crease can be greatly shortened or eliminated, and the crease mark degree and the copying length of the coiling head (inner ring) are improved.
The technical proposal of the utility model for solving the technical problem is that: the device comprises a steering roller and press rollers, wherein the press rollers comprise a front press roller and a rear press roller, the diameter of the steering roller is 500mm, and the diameters of the two press rollers are 200 mm; when the front pressing roller and the rear pressing roller are pressed down, the front pressing roller and the rear pressing roller are symmetrically distributed by taking the vertical central line of the steering roller as an axis, the included angle between the front pressing roller and the rear pressing roller is 55 degrees, and the roller bodies of the steering roller and the two pressing rollers are vertical to the central line of the unit.
Compared with the prior art, the utility model discloses following outstanding beneficial effect has:
1. the utility model can greatly shorten or eliminate the defect of head crease by optimizing the arrangement of the threading steering roller, the compression roller and the size of the roller diameter and matching with the threading control program;
2. the roller system of the utility model has high working efficiency, is suitable for continuous production lines and has high success rate;
3. the special book equipment is not needed, the equipment technology can be improved by the existing production line, the product quality is improved, the improvement cost is low, and the maintenance is convenient.
Drawings
Fig. 1 is a schematic layout view of the winding steering roller system of the present invention.
Detailed Description
The invention is further described with reference to the drawings and the detailed description. For convenience of description, the forward direction of the strip steel is taken as the front, and the reverse direction is taken as the back.
As shown in figure 1, the utility model discloses batch steering roll system includes steering roll 1 and compression roller, and the compression roller includes preceding compression roller 21 and back compression roller 22, steering roll 1 diameter be 500mm, two compression roller diameters are 200 mm.
When the front pressing roller 21 and the rear pressing roller 22 are pressed down, the front pressing roller 21 and the rear pressing roller 22 are symmetrically distributed by taking the vertical central line of the steering roller 1 as an axis, the included angle alpha between the front pressing roller 21 and the rear pressing roller 22 is 55 degrees, and the steering roller 1 and the roller bodies of the two pressing rollers are vertical to the central line of the unit.
When the device is used, the front press roll 21 and the rear press roll 22 are both in an open state before the strip steel 3 passes through the press rolls, after a coiling machine is selected and strip threading is confirmed to start, the strip steel 3 passes through the correspondingly uncoiled steering roll 1 and a gap between the two press rolls, and after the strip steel 3 passes through the front press roll 220.5 m, the strip steel 3 stops running; the front press roller 21 and the rear press roller 22 are pressed down. After the strip steel reaches the pressing position, the front pressing roller 21 starts to rotate, meanwhile, the strip steel 3 starts to continuously penetrate forwards, and the running speed of the front pressing roller 21 is 1.1 times of the penetrating speed; and the head of the strip steel enters a coiling machine along a strip threading guide plate, and after coiling is started and tension is established, the two compression rollers are opened and stop rotating.
The utility model discloses batch the crease seal condition: the length of a crease mark of the inner ring of the strip steel with the thickness of 1.4mm is less than 8 m; the crease mark length of the inner ring of the strip steel with the thickness of 2.0mm is less than 4 m; the crease mark length of the inner ring of the strip steel with the thickness of 2.5mm is less than 6 m; the crease mark length of the inner ring of the strip steel with the thickness of 3.0mm is less than 6 m.
It should be noted that while the invention has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit and scope of the invention.
