Abstract
The invention discloses a vertical loop device for a high-speed wire rod rolling mill. The device is arranged between an upstream rolling mill and a downstream rolling mill, and comprises a loop rising roller, a guide roller, and loop side plates arranged on two sides of the guide roller, wherein a guide slot with a guide centering function is formed in the roller surface of the guide roller. A rolled piece can always operate at the middle position of a loop rolling channel by the guide slot, the rolled piece is prevented from being scratched by the loop side plates, and the product quality is improved; the wire scratching phenomenon is eliminated, the rolling fault time is greatly reduced, and the working efficiency of the rolling mill is improved; and the wear of the loop side plates and a downstream rolling mill inlet guide and protection part is reduced, the service life is prolonged, and the rolling cost is reduced.
Description
Technical field
The present invention relates to the rolling equipment technical field, especially relate to the upright looper of a kind of high-speed rod-rolling mill.
Background technology
The high-speed rod pre-finishing mill is made up of the two-roller mill of four sortie horizontally and vertically alternatives, be to realize tension free rolling, and a upright looper is installed between per two milling trains, and in order to regulating the rotating speed of upstream milling train, thereby frame rolled piece volume second flow amount equates before and after guaranteeing.
Loop-rising roll and the deflector roll of existing upright looper all are plain-barreled rolls; high-speed rod plays the camber motion of cover back at loop-rising roll; because deflector roll can't be directed at rolled piece the centre position of upright loop-mill rolling passage; the kink side plate of rolling channel outlet both sides produces the rolled piece surface through regular meeting and scratches, and influences product quality.Especially for producing exempting from annealing, simplifying high value added products such as annealing and non-hardened and tempered steel of high cold heading performance, shape need to the wire rod bar shaped in the operation of rolling is very high, it is defective that the tiny scuffing of 0.05mm all may cause the product cold heading performance on the finished product, in roll regional bar shaped if cut greater than 0.2mm arranged, be reflected in and be interrupted folding on the finished product, naked eyes are difficult for finding, but mill product may be exactly waste product, very easily causes the quality of lot accident.The rolled piece surface produces when scratching, and also can go out a large amount of scraping of interruption-forming at kink, and scraping is stopped up rolled piece and often caused heap steel accident.
Summary of the invention
At the prior art deficiency, technical problem to be solved by this invention provides the upright looper of a kind of high-speed rod-rolling mill, and rolled piece is had the guiding centering function, prevents that rolled piece is by the scratch of kink side plate.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of high-speed rod-rolling mill founds looper, this device is located between upstream milling train and the downstream milling train, the kink side plate that it comprises loop-rising roll and guide roller and is located at the guide roller both sides, the roll surface of described guide roller is provided with the gathering sill with guiding centering function.
Described gathering sill is arc groove.
The both ends of described arc groove are provided with fillet.
The surface smoothness of described gathering sill is at least 6 grades.
The present invention compared with prior art has the following advantages: the gathering sill by deflector roll can make rolled piece operate in the centre position of loop-mill rolling passage all the time, prevents that rolled piece from by the scratch of kink side plate, having improved product quality; Eliminate the scraping phenomenon, greatly reduced rolling fault time, improved the milling train operating efficiency; Reduce the wearing and tearing of kink side plate and downstream rolling mill inlet guide, increase the service life, reduce rolling cost.

Among the figure: 1. rolled piece, 2. loop-rising roll, 3. guide roller, 4. upstream milling train, 5. downstream milling train, 6. kink side plate I, 7. kink side plate II, 8. gathering sill, 9. fillet, 10. guide roller inspection panel.
The specific embodiment
Contrast accompanying drawing below, the description by to embodiment is described in further detail the specific embodiment of the present invention.
As shown in Figures 1 to 4, a kind of high-speed rod-rolling mill founds looper, should be located between upstream milling train 4 and the downstream milling train 5 by upright looper, it comprises loop-rising roll 2 and guide roller 3 and the kink side plate that is located at the guide roller both sides, be kink side plate I 6 and kink side plate II 7, the roll surface of guide roller 3 is provided with the gathering sill 8 with guiding centering function.After rolled piece 1 entered upright looper, and 2 pairs of rolled pieces of loop-rising roll play cover, rolled piece moved along arching trajectory, and spacing by 8 pairs of rolled pieces of gathering sill makes rolled piece can operate in the centre position of loop-mill rolling passage all the time, did not produce scratch not contacting with the kink side plate.
Draw the stressed maximum of guide roller on the outlet side top of upright looper according to the track of rolled piece, the guide roller at this place is arranged to the guide roller of tape guide groove, and the centering effect of rolled piece is better.In order further to improve the guiding centering effect, be equipped with the gathering sill with guiding centering function on all guide rollers that it should upright looper and the roll surface of loop-rising roll.
Preferably, gathering sill 8 is arc groove.The both ends of arc groove are provided with fillet 9, to prevent wedge angle rolled piece are scratched.The surface smoothness of gathering sill is at least 6 grades, and surface smoothness can reduce well the rolled piece wearing and tearing, improves the rolled piece quality.
Rolled piece needs through several milling trains in the whole operation of rolling, the rolled piece cross dimensions difference between two milling trains at diverse location place, and the radian size of the gathering sill on the guide roller adapts to the workpiece measurement of this position, guarantees the centering effect.
Arc groove on the guide roller can be adjusted according to rolled piece cross dimensions difference, can or be U-shaped groove for the arc groove of different radian sizes.Also made guide roller inspection panel 10 simultaneously, whether the direction recess geomery that is used on the check guide roller meets standard-required, makes regular check in can and using in direction recess processing, and whether the check direction recess meets the requirements.
After the improvement, operating rolled piece contact the generation scuffing with the kink side plate, has not effectively improved product quality.Kink goes out the every 1-2 of scraping hour of interruption-forming before improving needs cleaning once, also often causes the heap steel because rolled piece is stopped up in scraping, has reduced rolling fault time after the improvement, has improved operating rate of rolling mill, and has reduced the wearing and tearing of kink side plate and downstream rolling mill inlet guide.
By reference to the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
