Abstract
In a method and device for pickling a rolled metal, in particular, steel strip, the metal strip (1) is fed to a regulated pickling process. In order to carry out the pickling process not only on the basis of conventional pickling parameters but rather taking into consideration additional parameters from outside of the pickling vat, it is proposed to regulate the pickling process, in addition to the pickling medium parameters, by parameters of the coil (2) and/or metal strip determined and/or measured before the metal strip (1) enters the pickling section (3).
Description
Technical field
The present invention relates to the acid washing method and the equipment of metal band rolling and especially steel band, described metal strip is supplied to an acid cleaning process of being adjusted.
Background technology
From DE19743022A1, known a kind of metal strip acid washing method, it is based on measuring behind pickling installation on the travel direction, and in the method, the defect type of grasping according to surveying instrument is regulated acid content, metal content and especially iron level and band parameter such as material and the geometrical dimension in pickling parameter such as pickle solution temperature, metal strip translational speed, the pickle solution.With regard to this method, can only determine defective afterwards and infer favourable pickle solution.Therefore, adjust distance and only control pickling installation itself.
Another known method (EP0482725A1) is with scroll fluid work, and described scroll fluid results from the pickling container.Like this, people try hard to the pickling medium consumption and obtain best pickling result minimumly.Can so realize this result, promptly adjust eddy current in the pickling medium according to the translational speed of wanting the pickling band.Can not expect to obtain very effective result.
From EP0602437B1, known the method for another kind pickling rolled strip in pickling installation.This method is based on a particular job mode of the continuous pickling tank that is provided with in a plurality of front and back.In pickling tank, by at least ribbon motion planar next door, above or below the nozzle that is arranged on the pickling tank spray acidiferous pickling medium, wherein can control nozzle and with the amount injection pickling medium of preliminary election arbitrarily with changing.Here, can the preliminary election acid concentration and/or the jet exit speed of medium temperature and/or pickling medium.
Summary of the invention
Task of the present invention is not only will carry out acid cleaning process according to common pickling parameter, and will consider other parameter that pickling tank is outer.
According to the present invention, so finish being proposed of task, promptly except that the pickling parameter, also adjust this acid cleaning process according to the roll coil of strip of before this metal strip enters pickling portion, having determined and/or having measured and/or the parameter of metal strip.Its advantage is, sets up the pickling parameter in advance, thereby avoided underpickling or over-cleaning, suitably regulates acid concentration and for the acid amount and use pickling medium thus economically, can go out suitable temperature with other pickling parameter the preceding calculated in advance together.In addition, can consider by pre-descaling device after the casting, oxide skin and other coating removed after thermal distortion and the cooling.Therefore, the present invention has also considered, oxide skin is broken in (by the straightening device), wherein cracks and hole in the oxidation cortex, and they have increased acidleach profit surface.Concerning remove descaling by abrasion or fluid power mode, can reduce will be in acid cleaning process dissolved oxide skin amount, thereby can shorten the pickling time according to pre-de-scaling type.When improving the metal strip temperature before entering pickling tank, under the pickling temperature of the best, prolonged the duration of contact of strip surface and pickling medium.The heating distance of metal strip is shortened and the pickling time has shortened.If remove descaling and dwindle the dissolved oxide skin amount of wanting before it enters pickling tank by the laser optics mode, then the oxide skin pickling time also shortens.
In addition, method is used this method in such a manner, promptly one sets up computation model and comes the pre-setting acid cleaning process with roll coil of strip observed value and adjust according to an adjustment computation model of having considered the observed value of oxide skin, liquid pool temperature, pickling medium temperature and/or acid concentration at least.For example, need not resemble again done at present estimate the oxide skin amount.The combination of an additional oxide skin computation model has appearred.Optimized target component like this can be: minimum energy consumption, and diversified volume group, to the more rapid reaction of surperficial impurity level and type, pickle solution consumption and loss on acid washing minimum suppress over-pickling and underpickling.In adjustable pre-de-scaling unit, can determine thickness, shape, distribution and the color of oxide skin by the oxide skin measuring apparatus.For this reason, adopt accurate computation model.
In design of the present invention, stipulated, adjusted or the topworks of the pickler of resetting according to the oxidation cortex value of before pickling portion, measuring.So, realized the adjustment of pickling portion transit time the shortlyest.
Specifically make such regulation, i.e. observed value outside a zone measurement be arranged in pickling portion on direction of motion before descales layer or coating and these observed values are used to reset topworks and/or the balancing side value or the calculated value of pickling portion.
So considered other parameter outside pickling portion, promptly adjusted the pickling time according to the band input information and the equipment adjustment situation of the roll coil of strip.
Another flexible program stipulated, the observed value of being grasped relevant with coating or oxide skin is used to adjust a pretreatment unit before being connected on pickling portion.Thus one, can adjust the parameter of pickling medium according to pretreatment unit more accurately.
In addition, also be favourable with reset the evenly topworks of this pretreatment unit and pickling portion of observed value or calculated value.
The pickling installation of metal band rolling and especially steel band is so finished being proposed of task, wherein said metal strip is being handled on the direction and can is being supplied to a pickler and draft the adjustment of a plurality of parameters for this pickler from a roll coil of strip, and promptly observed value can be set up the executive device that computation model and adjustment computation model are transformed into pickling portion through one from the roll coil of strip or roll coil of strip metrical information receptor.So, can regulate and drive the work of pickling portion more economical and more accurately, this has brought above-mentioned advantage.
Proposed in the design of equipment, roll coil of strip observed value receptor can be adjusted the observed value input in the computation model.Architecture computer has utilized general metal strip input information here.In addition, can go out the oxidation cortex by accounting equation and according to Model Calculation, so that the topworks slowly and fast of the preset or the pickling portion of resetting evenly.
Be that has stipulated other application scenario, an observed value receptor and relevant observed value can be used to the to reset topworks of pickling portion with coating or oxide skin.
Stipulated according to further feature, a pretreatment unit is set in the front of pickling portion, its observed value can be transfused to be adjusted in the computation model.Recognizing the suitable analysis of also passing through under the situation of necessity roll coil of strip information and instantaneous equipment adjustment situation, pretreatment unit can have influence on the pickling time.Pretreatment unit can be a preheating unit, a mechanical type, an abrasion formula, a hydraulic type, a laser optics formula or a scale breaker that utilizes the oscillation technology device.
So obtain another improvement project, promptly between pretreatment unit and pickling portion, inserted an induction heater that is used for band.Insert the induction heater of metal strip and it is used for adjusting apace the metal strip temperature and sets up the metal strip pickling temperature in pickling portion.
