Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The embodiment of the invention provides a control method for strip steel deviation, which is applied to a leveling unit comprising an uncoiler winding drum, an inlet vertical roll guide and guard device, a straightening machine, a leveling machine, an outlet vertical roll guide and guard device, a coiler winding drum, a centering device and an opposite side device, wherein in the embodiment of the invention, the leveling machine is a four-roll mill, as shown in figure 1, the method comprises the following steps:
step 101: after the head of the strip steel is fed with the roller, the strip steel is subjected to deviation correction through the inlet vertical roller guide device, is continuously threaded to the outlet of the temper mill, is subjected to deviation correction through the outlet vertical roller guide device, and is controlled to be threaded in the whole line, and the central lines of the strip steel at the position of the uncoiler reel, the position of the steel passing channel and the position of the coiler reel are located on the same straight line.
Step 102: and controlling the centering device and the edge aligning device of the strip steel, automatically correcting the strip steel after tension is established, and switching to a manual mode after the tension is cancelled and keeping the current position unchanged.
The invention corrects the deviation of the strip steel through the inlet vertical roller guide device after the head of the strip steel is fed with the roller, continues to pass to the outlet of the temper mill, and corrects the deviation through the outlet vertical roller guide device, thereby timely correcting the deviation of the strip steel possibly caused by the tower shape of the supplied material, and preventing the leveling start deviation caused by the deviation of the initial position of the strip steel by controlling the central lines of the strip steel at the reel position of an uncoiler, the steel passing channel position and the reel position of a coiler to be positioned on the same straight line after the strip steel is completely threaded.
The centering device (CPC) and the opposite side device (EPC) of the strip steel have the functions of automatically centering and correcting the opposite side of the strip steel and keeping the center and the opposite side of the strip steel basically unchanged, thereby meeting the requirements of continuous centering and opposite side. The original design control mode of the centering device and the opposite side device is used for automatically rectifying deviation of the strip steel after tension is built in the production line, the automatic deviation rectification is automatically carried out on the strip steel after the tension is cancelled, however, under the condition that the production line needs to stop midway due to the fact that the surface quality is checked or the working roller is polished due to the fact that the tension is cancelled, the centering device and the opposite side device are automatically switched to the central position mode of the equipment, meanwhile, the steel coils on the uncoiler and the coiling machine are returned to the central position of the equipment, the steel coils on the uncoiler and the coiling machine and the strip steel on the binding line are staggered in different degrees, if the production line is started after the tension is built again, the centering device and the opposite side device still recover to the automatic deviation rectification mode, and the phenomenon of the strip steel is.
According to the invention, through controlling the centering device and the edge-aligning device of the strip steel, the strip steel is automatically corrected after tension is established, and the strip steel is switched into a manual mode after the tension is cancelled and the current position is kept unchanged, so that the phenomenon of dislocation between steel coils on the uncoiler and the coiler and the strip steel on the steel passage is ensured, and the phenomenon of deviation and steel rolling after the strip steel is restarted is prevented.
In conclusion, the invention avoids the phenomenon that the strip steel deviates and rolls, not only improves the quality of the strip steel, but also prolongs the service life of the working roll, reduces the production cost, has simple operation, easy control and good application effect, improves the market competitiveness of the product, and also has good application value.
It should be noted that the center lines of the strip steel at the position of the uncoiler drum, the position of the steel channel and the position of the coiler drum are located on the same straight line, specifically, the center line of the strip steel at the position of the uncoiler drum, the center line of the strip steel at the position of the steel channel, and the center line of the strip steel at the position of the coiler drum are located on the same straight line. In addition, the central line is the central line of the strip steel in the width direction.
Further, the method for controlling the deviation of the strip steel further comprises the following steps:
and after the strip steel is coiled, controlling the central line of the strip steel in the width direction and the mechanical central line of the winding drum of the uncoiler to be positioned on the same straight line.
Specifically, for the uncoiling control of the uncoiler, an operator can mark the position of the mechanical center line of the uncoiler by a straight line, and after the uncoiler performs automatic or manual coiling operation, the horizontal position of the coiling trolley is adjusted according to the width of incoming strip steel, so that the center line of the strip steel in the width direction and the mechanical center line of a coiling block of the uncoiler are controlled to be positioned on the same straight line. The phenomenon that the strip steel deviates and rolls can be further avoided through the control operation.
Further, the method for controlling the deviation of the strip steel further comprises the following steps:
and controlling the automatic centering distance deviation of the inlet vertical roll guide device and the outlet vertical roll guide device to be 5-15 mm.
Specifically, the deviation of the automatic centering distance is 5-15mm, the band steel is easy to be damaged when the deviation of the automatic centering distance is too small, and the centering effect is weakened when the deviation of the automatic centering distance is too large. Preferably, the deviation of the automatic centering distance is 10mm, and the deviation of the automatic centering distance of the inlet vertical roll guide device and the outlet vertical roll guide device is set to be 10mm in advance, namely the deviation of the distance between the vertical roll guide device and the edge of the strip steel is 10mm, so that the effectiveness of the deviation rectifying strip steel of the inlet and outlet vertical roll guide device is ensured, and the phenomenon that the strip steel is damaged due to clamping caused by over-small setting is prevented.
Further, the method for controlling the deviation of the strip steel further comprises the following steps:
and controlling the pressure deviation of the two sides of the straightening roll in the straightening machine within 30 KN.
Specifically, a straightener is usually arranged between an inlet pinch roll and a leveler and used for straightening strip steel, the last pair of straightening rolls of the straightener can enable the head of the strip steel to slightly bend downwards so as to be easy to penetrate into the leveler, and along with increasing requirements on leveling production of high-strength steel, dual-phase steel and the like, the design capability of the straightener is gradually improved in order to ensure good straightening effect, so that the control accuracy and stability of straightening pressure on two sides also become important factors influencing the deviation of the strip steel. In the invention, each group of straightening rollers are calibrated one by one, when the pressure sum of a single straightening roller is not more than 50KN, the pressure deviation of the two sides of the straightening rollers is controlled within 30KN, and the pressure deviation is determined as the zero position of the straightening rollers, so that the calibration of all the straightening rollers is completed, thereby ensuring the control precision of the pressure of the two sides of the straightening machine, ensuring the stability of the straightening process of the strip steel and preventing the strip steel from deviating and rolling caused by the pressure deviation of the straightening machine.
Further, the method for controlling the deviation of the strip steel further comprises the following steps:
the automatic roll gap leveling function of the planishing mill is shielded, and the deviation of the calibrated rolling force at two sides of the planishing mill is controlled within 10 t.
Specifically, the leveler is a four-high rolling mill, which is disposed behind the leveler and is generally used for leveling a hot-rolled steel coil of plain carbon steel, fine carbon steel, or low alloy steel at normal temperature, improving the strip shape, and eliminating the yield point. In the normal production process of the temper mill set, accurate rolling force measurement and control are the key for guaranteeing the shape and the surface quality of the temper mill after the temper mill set is leveled, and meanwhile, the control deviation of the rolling force on two sides is the important factor for guaranteeing the stability of the temper mill set. Most hot rolling planishing mill sets are in a constant rolling force control mode, the original rolling control mode of the migrated steel hot rolling planishing mill set is a rolling mill roll gap automatic leveling function, namely when the rolling forces on two sides are deviated, the rolling mill automatic leveling function enables the side with larger rolling force to be slightly lifted and the side with smaller rolling force to be slightly pressed down, the dimensional deviation of the incoming strip steel in the shape of a wedge and the like is ignored under the control strategy, the roll gap control irregularity of the rolling mill is caused, and the problem of strip steel deviation and rolling in the high-speed production process is easily caused. However, the embodiment of the invention can avoid the phenomenon of deviation and roller grinding of the strip steel caused by improper adjustment of the roll gap in the high-speed rolling process by shielding the automatic leveling function of the roll gap of the rolling mill, and can also increase the manual leveling function of the roll gap of the rolling mill, thereby improving the shape of the incoming material as much as possible, allowing an operator to adjust the roll gap, and accelerating the production after the adjustment is completed. In addition, the embodiment of the invention eliminates the deviation of the rolling force at two sides caused by the roller or the housing of the rolling mill and the like as far as possible when the rolling mill is calibrated by improving the calibration precision of the temper mill, particularly reducing the allowable deviation of the rolling force at two sides, ensures the stability of the control of the rolling force in the normal leveling process and prevents the problem of steel deviation and steel grinding of strip steel caused by overlarge deviation of the rolling force at two sides.
Further, the method for controlling the deviation of the strip steel further comprises the following steps:
and controlling the deviation of the central lines of the uncoiler drum, the inlet vertical roll guide and guard device, the straightening machine, the leveling machine, the outlet vertical roll guide and guard device and the coiler drum within 1.5 mm.
