Abstract
The invention relates to the field of strip steel rolling and particularly relates to a strip steel coil threading method. The high-intensity strip steel coil threading method comprises the following steps: a first grating at the inlet of a pre-leveler is first opened, and a second grating at the outlet of the pre-leveler, a third grating at the outlet of a finish-leveler, and a fourth grating at the inlet of a pinch roll are closed; the head of the strip steel is led to pass though a threading device manually, is conveyed to the pre-leveler to be straightened, is conveyed to the finish-leveler by a cutting head to be straightened, and then is led to pass through the pinch roll; and then an automatic control device is opened, the second grating, the third grating and the fourth grating are opened in sequence, a normal threading procedure is started, and the head of the strip steel passes through a looping pit and a lateral guide device and then is conveyed to a rolling mill to be rolled. According to the high-intensity strip steel coil threading method provided by the invention, the head of the strip steel is conveyed to the pinch roll manually, and then the automatic control device is started; the method is applicable to high-intensity steel coil with the thickness of more than 2.5 mm; and since the method is adopted, the phenomenon of bounce and unwinding of the steel coil never occurs since the method is adopted, so that the production efficiency is improved.
Description
Technical field
The present invention relates to the belt steel rolling field, relate in particular to a kind of band steel coil of strip and wear the band method.
Background technology
For convenient transportation all can be rolled into coil of strip, coil of strip will be worn the band operation to the band steel before getting into the product line before processing; As shown in Figure 1; Flow process before the belt steel rolling is that coil of strip is with steel 1 head earlier through tape threading apparatus 3 after uncoiling on the uncoiler 2; Send into then and just rectify machine 4 alignings; The aligning back is sent into the smart machine 6 of rectifying again by crop shears 5 crops and is aligned, and then enters into kink hole 8 by pinch roll 7, and it is rolling to send into roll mill 10 by lateral guide 9 at last; Existing normal threading is after manually will delivering to the porch of just rectifying machine 4 with steel toe portion; Carry out full automatic normal steel band feeding by automaton; The gateway of just strong machine 4, the smart inlet of rectifying machine 6 outlets and pinch roll 7 all are equipped with grating, and the signal that automaton sends through grating confirms to be with the position of steel toe portion to carry out feeding control; Because uncoiler 2 is shorter to the distance of just rectifying between machine 4 inlets; Have only tape threading apparatus 3 to push down plate during feeding; When producing high thickness and high-intensity band steel, tape threading apparatus 3 often can't be pushed down the band steel, in the process of self-feeding, is prone to cause the coil of strip bounce-back to scatter.The coil of strip thickness that the blanking line can be processed is 0.6 millimeter to 3.5 millimeters; When the coil of strip thickness of producing reaches 3.0mm, yield strength reaches 800M, because steel plate thickness is blocked up; Yield strength is strong excessively; Cause wearing when band coil of strip to be prone to bounce-back and to scatter, the coil of strip after scattering generally need be handled about 2 hours, not only lost time but also in processing procedure, also might cause the injury of personnel and equipment.
Summary of the invention
Technical problem to be solved by this invention provides a kind of high-intensity band steel coil of strip and wears the band method, and this method is restarted automaton after using and manually the steel band head being delivered to pinch roll, has avoided the coil of strip bounce-back to scatter to influence and has produced.
The present invention is achieved in that a kind of high-intensity band steel coil of strip wears the band method, at first opens first grating of just rectifying the machine inlet and second grating that will just rectify the machine outlet, smartly rectifys the 3rd grating of machine outlet and the 4th grating that pinch roll enters the mouth is closed; Then manually will be with steel toe portion earlier through tape threading apparatus, and send into just strong machine aligning again, pinch roll is passed after sending into smart strong machine aligning again by the crop shears crop in the aligning back; Open automaton then, open second grating, the 3rd grating and the 4th grating in order, get at last and wear tape program normally, band steel toe portion sends in the roll mill rolling through kink hole and lateral guide.
High-intensity band steel coil of strip of the present invention is worn the band method; After manually delivering to pinch roll with the steel band head, use restarts automaton; It is high-intensity coil of strip more than 2.5 millimeters that this method is used in thickness, and the phenomenon that coil of strip bounce-back is together scattered did not take place after bringing into use certainly, has improved production efficiency; This is worn the band method and is equally applicable to the more coil of strip of oil surface below 1 millimeter; The more coil of strip of oil surface below 1 millimeter is when normal threading; Just rectify the machine porch because the band steel is only manually delivered to, depend merely on uncoiler during feeding, because surface oil is more in feeding; Steel plate can skid, normally feeding.As use manually with steel band deliver to restart the method for self-threading tape program behind the pinch roll after, when self-threading tape, have the machine of just rectifying simultaneously, smartly rectify machine and pinch roll carries out feeding together, thereby guarantee to be with the steel can normal feeding.
Description of drawings
Fig. 1 wears the band system schematic for the band steel.
Among the figure: 1 band steel, 2 uncoilers, 3 tape threading apparatus, 4 are just rectified machine, 5 crop shears, 6 smart machine, 7 pinch rolls, 8 kinks hole, 9 lateral guides, 10 roll mills, 11 first gratings, 12 second gratings, 13 the 3rd gratings, 14 the 4th gratings rectified.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in the restriction scope of the present invention.Should be understood that in addition those skilled in the art can do various changes or modification to the present invention after the content of having read the present invention's statement, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment
As shown in Figure 1, a kind of high-intensity band steel coil of strip is worn the band method, at first open first grating 11 of just rectifying machine 4 inlets and will just rectify machine 4 outlets second grating 12, smartly rectify the 3rd grating 13 of machine 6 outlets and the 4th grating 14 that pinch roll 7 enters the mouth is closed; Coil of strip manually will be with steel 1 head earlier through tape threading apparatus 3 after uncoiler 1 uncoiling, send into just strong machine 4 alignings again, and pinch roll 7 is passed after sending into smart strong machine 6 alignings again by crop shears 5 crops in the aligning back; Open automaton then, open second grating 12, the 3rd grating 13 and the 4th grating 14 in order, get at last and wear tape program normally, band steel 1 head is sent in the roll mill 10 rolling through kink hole 8 with lateral guide 9.
Each step is all responded to through grating in the process of self-threading tape; As have nothing to do with the black out grid; The grating everywhere of subsequent step will be sensed the existence of band steel in advance; Can't start automaton thereby can cause, must open follow-up grating more in order manually wearing when bringing to pinch roll.
