Brief description of the drawings
By reading the detailed description of non-limiting example being done with reference to the following drawings, it is more obvious that other features, objects and advantages of the present invention will become:
Fig. 1 is the control principle schematic diagram of jockey pulley and inlet seal roller.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following examples will contribute to those skilled in the art further to understand the present invention, but not limit in any form the present invention.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, can also make some distortion and improvement.These all belong to protection scope of the present invention.
The present invention has adopted Optimized-control Technique, can effectively control band steel small tension receiving coil in vertical annealing furnace, and has substantially stopped the phenomenon of heap steel before dancer roll, all can use for reference use for the band steel small tension control of the vertical annealing furnace of all use dancer rolls.Particularly, according to dancer roll tension control method provided by the invention, comprise step: according to the strip tension of expecting, set the pressure of the position control cylinder of dancer roll; Control the tension force addition speed being added on jockey pulley and inlet seal roller by closed loop PI, thereby control the tension force with steel, wherein, the position deviation that is input as dancer roll that described closed loop PI controls, described closed loop PI controls and is output as described tension force addition speed.Described tension force addition speed is added on described inlet seal roller after being multiplied by coefficient 1-K, and wherein, in described coefficient, the span of K is-1<K<1, and the symbol of K and the opposite direction of addition speed.Described tension force addition speed is added on described inlet seal roller after being multiplied by certain coefficient.
More specifically, it will be appreciated by those skilled in the art that in corrosion-resistant steel vertical bright annealing furnace, stove internal tension generally produces tension force by additional tension and the deadweight of band steel, and stove internal tension is larger, the more bad control of template, and therefore, general additional tension is the smaller the better.In order to reach the control with the additional small tension receiving coil of steel in furnace for brightness, between the general furnace top roller at vertical bright annealing furnace and inlet seal roller, is furnished with dancer roll, the position of dancer roll can regulate by the low rubbing cylinder with proportional valve control, and position transduser is also installed simultaneously on dancer roll.In the time of the pressure of dancer roll position control cylinder and band steel actual tension balance, dancer roll just can be stabilized in a certain position.In the time that the strip tension of vertical bright annealing furnace produces fluctuation, the position of dancer roll can produce change thereupon.Therefore, control strip tension in annealing furnace, only need to preset the pressure of cylinder, then control the position of dancer roll.
Further, the position control of dancer roll adopts closed loop PI mode, is input as dancer roll position deviation, is output as tension force addition speed (this addition speed is superimposed on jockey pulley).In the time that strip tension is less than normal, dancer roll position declines under cylinder promotes, and now jockey pulley is applied the addition speed of negative sense, and it is large that strip tension becomes, and dancer roll rises to normal position; In the time that strip tension is bigger than normal, rise in dancer roll position under strip tension effect, and now jockey pulley is applied the addition speed of forward, and strip tension diminishes, and dancer roll drops to normal position.
Further, because strip tension in vertical furnace for brightness is smaller, and jockey pulley and dancer roll spacing are relatively long, simultaneously between them also across inlet seal roller, therefore, the position of dancer roll is more responsive for the velocity variations of inlet seal roller is compared jockey pulley velocity variations.Therefore,, in the time that unit acceleration and deceleration cause strip tension fluctuation, because jockey pulley exists hysteresis quality (inlet seal roller relatively) to the position control of dancer roll, often easily cause between jockey pulley and sealed roller and produce and pile steel phenomenon.Based on this, (for example coefficient is 1-K to be necessary that the addition speed at sealed roller place is multiplied by a coefficient; Wherein-1<K<1, the symbol of K and the opposite direction of addition speed).
Above specific embodiments of the invention are described.It will be appreciated that, the present invention is not limited to above-mentioned specific implementations, and those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present invention.
