Abstract
The present invention describes equipment for the pickling and metallic coating, such as galvanizing, of a continuously running metal strip, successively comprising along the run direction at least a pickling unit, a furnace and a coating unit, and for which the metal strip entering the pickling unit is by default a hot-rolled product. The equipment according to the invention is characterized in that: a rolling mill for elongation/limited reduction of strip thickness, referred to as a skin-pass rolling mill, is positioned between the pickling unit and the furnace; the furnace imposes a heat cycle on the strip that makes it possible to control a restoration of strip structure (that is to say free of strip recrystallization) and imposes, at the outlet of the furnace, a heating of the strip to the temperature that is required at the inlet of the metallic coating unit. A pickling and metallic coating process is also proposed.
Description
Technical field
The present invention relates to the pickling of metal tape as described in the preamble according to claim 1 and metal coating equipment, and
And further relate to correlation technique as described in the preamble according to claim 14.
Background technology
So far, steel heat rolling line enables the metal tape providing thickness to be typically larger than close to 1.2 mm.These lines are general
Need to combine continuous casting, the thickness of its product paid is about 200 to 250 mm, thus needing by means of hot-rolling mill housing group
Part, to obtain being obviously reduced of thickness, especially when needing to realize close to the minimum thickness of 1 mm.For realizing this knot
The energy balance of this kind equipment of fruit and size are quite heavy.In recent years, new ESP（Strip steel without a head produces）Type
Metal continuous cast method enables to obtain, using the more widgets of hot-rolling mill housing, the steel gold that minimum thickness is of about 0.7 mm at present
Belong to band.Very possible within the coming years or decades, by such method of the example with regard to ESP type, technically
The less thickness of such as about 0.5 mm will be enabled.It should also be noted that such method also allows for continuously producing metal
Band, and therefore highly effective in terms of productivity ratio.Additionally, for from continuous casting until the rolling of relatively small thickness terminates, these methods
Make product change the required energy balance to reduce with respect to existing method.Generally, such band（Strip steel, strip）Manufacturer
Therefore there is at least one continuous casting line being attached to hot-rolling mill housing unit, and it is attached in outlet and reels machine system.
Therefore, these bands are to be paid that is to say, that with rolling without pickling to have oxidized surface " hot " coil form
The form of band.
Therefore if it is necessary to " hot " the metal coating operation with execution such as plating, then pass through " hot " explained above
The band that technique is obtained must be acid washed further, is then finally electroplated.In the case of conventional hot preparation route, its
The output thickness of produced band then generally will be at least above 1.2 mm.Additionally, in order to obtain thinner and also have good
The coated metal tape of punching press property（For example through plating）It is necessary to these bands cold rolling make its thickness be obviously reduced.Therefore, phase
For the processing hardening of initial reduced levels, the cold rolling processing that can cause steel is hardened.However, the advantage of this method contributes to
Realize final good punching press property, but need first to make rolled metal band before plating at the downstream of mill operation
Annealing, so that be possible to finally obtain especially good punching press property.US 4 436 292 A describes to the band entering
Carry out cold rolling, annealing and the example electroplating route of then plating.
From for producing little thickness（A few tenths of mm, such as 0.7 mm）Band thermal process（Such as ESP type method）
Start, the little thickness of the band of these " hot " technique productions gradually returns to the area of the larger thickness via cold rolling production explained above
Between.
For the minimum thickness entering close to the band of 1.2 mm, in US 6 761 936 B1 of calendar year 2001, describe one kind
The just traveling that continuously pickling obtains from thermal process with plating（Or winding）And the method for the product without pickling.This
Method mainly provides and carries out pickling by the method impregnating the metal tape being continuously traveling in bathing in liquid alloy and electroplate coating
The embodiment of the form of equipment, this equipment includes successively along direct of travel：At least pickling unit（Include cleaning in its exit
And drying）, Yi Jilu, the temperature for making the band after pickling reaches for final plating stage needed for liquid zinc bath porch
Temperature.Constantly require on market to reduce production cost and improve quality, this especially to be produced by reducing the following：Produce
The size and number of equipment, operation team's resource and energy expenditure, and also process time.Plating has thickness in input
Still also there is the hot product of the larger thickness of good punching press property close to the thickness of the relative thin of 0.5 mm, completely in output
Meet the demand of steelmaker and its client.Thus, the method described by US 6 761 936 B1 does not obviously meet such difficulty
Topic.Finally, even if the hot product of today and tomorrow entering the pickling described in US 6 761 936 B1 and electroplating device
Mouth presents such as 0.7 mm or less thickness, and the input of band body and output thickness will be almost unchanged all the time.Additionally, for example
The electroplated coating quality of the dipping in heating bath according to US 6 761 936 B1 and dewatering cannot be in surface roughness and band
Flatness aspect optimized.Finally, most of bands in exit therefore will must not have good punching press property.Due to
Lack cold rolling manipulation, this equipment therefore has as a drawback that：The electroplated product of thickness reduction can not be paid（For example from
In the range of 0.5 mm to 5 mm）, keep the mechanical intensive property of output products so as to machinery substantially with input product simultaneously
Intensity property is identical.
With need not cold rolling and and then anneal in the case of reduce through pickling and electroplated product（In upstream from without pickling
Hot product produced by）Thickness be target, the explanation of Patents US 8 163 348 B2 or EP 1 861 517 B1
Book proposes such solution, and based on the equipment described in US 6 761 936 B1, this solution proposes will be cold rolling
Unit（The thickness causing 6.5% to 10% reduces）It is positioned the downstream of electroplating unit that is to say, that passing through cold rolling electroplating（Coating）
Product.Metal tape stands the operation by cold rolling reduce thickness, and described thickness reduces or even is limited to 10% all the time, and rolls it
There is no the annealing in downstream afterwards, described thickness reduces and is not suitable for being obtained in that the best in quality for plating tape is：On the one hand,
Due to the different power of the rolling between substrate and adding layers and the effect of elongation, the intensity of coat has by the wind of apparent damage
Danger；On the other hand, because downstream does not have annealing operation, there is the not good enough risk of the punching press property of band, especially for very great Cheng
The thickness of degree reduces.
Content of the invention
Therefore, an object of the invention is to provide a solution to be used for expanding from the output of continuous metal painting method
Product thickness range, give tacit consent to this continuous metal painting method supply be from thermal process preparation band roll up obtained
The steel band without pickling advanced.The program being provided should also ensure that the band of coating unit porch has adding of minimum degree
Work is hardened, even if implement tape thickness reducing so that it is also such for expanding described scope.Finally, this scheme should make it possible to
Need not pass through cold rolling（Anneal including making band（Recrystallization）Stage）Reduce the stage of big thickness, also will can keep final product simultaneously
The good press quality of product.
Equally, the present invention also should can ensure that combination with the continuous combined method of next stage：Pickling, thickness reduce, coarse
The holding of the optimal properties of material after the improvement of degree and flatness, thickness reduction, and the deposition of metal coating.Metal coats
Plating mainly on tape, for example, pass through the hot tempering process in the liquid metals bath include various types of metal alloys,
So that steel is carried out with plating protection, then it is for ensuring that the relevant treatment of the market quality of product after coating.Can also carry
For any other plating method, the such as plating in suitable electrobath.
Therefore, the scheme of apparatus-form is provided by the feature of claim 1.Finally, by the feature of claim 14
Correlation technique is provided.
Pickling and metal coating from the metal tape for being continuously traveling（For example electroplate）Equipment start, along traveling side
To including successively：At least one pickling unit, stove and coating unit（For example the liquid metals as coating agent is bathed, or electrolysis
Bath）, and the metal tape that wherein acquiescence enters pickling unit is hot-rolled product,
It is characterised by according to the equipment of the present invention：
- for tape thickness limited elongation/reduction rolling device, referred to as skin pass rolling device, described skin pass rolling device
It is positioned between pickling unit and stove；
- stove applies thermal cycle to band, and this enables control over the recovery of band structure（I.e., it has no band recrystallization）, and
The temperature needed for the porch of metal coating unit will be heated in the outlet of stove with temperature（Machine is heated or cooled by suitable
Structure）.
Therefore, produced it is ensured that producing such plating with combining of the temperature controlled continuous processing in downstream by limited reduction

State, but temperature need not be made to rise above described scope（REST）In included temperature that is to say, that need not rise to
It is related to the higher temperature with recrystallization（By including the part of cross-hatched（RECR）Represent）, wherein recrystallize and commonly referred to move back
Fire, it actually even relates to crystal grain and grows up（Be exclusively used in being obviously reduced thickness cold rolling after annealing required）.By this
It can be ensured that the band leaving stove and then being coated will keep very good property, especially very good rushes the mode of kind
Pressure property.
Fig. 3 presents temperature T of three possible selection of control parameters of the Restoration stage targeted for Fig. 2（℃）With
The time（s）The curve chart of change, these three parameters select e.g. to be directed to the Three Estate of band or band reduces in stove（4）Enter
Three conditions at mouthful.Stove（4）At least one section guarantee for every in controlling the possible parameter of Restoration stage to select
One is provided with the thermal cycle with heating followed by temperature stabilization horizontal versions, and in this example, temperature stabilization level is located respectively
Three required temperature when recovering（Trest1, Trest2, Trest3）One of place, and and then at outlet of still, be heated to gold
Belong to the entrance of coating unit（Bath）The required band temperature in place（For example for the hot dipping in conventional electroplating baths, T=465 DEG C）.Thus control
The thermal conditioning path of stove processed, to optimize temperature cycles, this temperature cycles is applied to travel across at least one chamber of stove
Carry, target is to execute the Restoration stage of carrying material according to the external of described band and internal condition, and and then adds at the end of recovering
The torrid zone, minimized especially for the persistent period making the active of recovery band heat/cool down（Energy requirement minimizes）.Should
Point out, recover the persistent period（Dt_Rest）End can be extended beyond towards bath heating tape stage that is to say, that
Outside stove, therefore potentially and advantageously the active energy without stove is contributed.
Finally it is pointed out that according to the pickling of the metal tape being continuously traveling of the present invention and plating method, energy
Enough make initially to be exclusively used in controlling the single thermocycle stage with recovering achieving at least part of band recrystallization（It is practically even
Crystal grain is grown up）In the sense that be extend.
This is because, initially it is exclusively used in controlling the single thermocycle stage with recovering can extend at the heat of such as annealing
In the reason stage, it requires to be provided with has the suitable stove heating and cooling down thermal power.Annealing is passed through to include at least first Restoration stage,
Followed by part or complete recrystallization stage and last optional crystal grain long megastage.The rolling of this especially suitable stove upstream
The reduction of the relatively large degree of device processed, such as more than 5%, practically even reach at least 40%.This is because, even if stampability
Verify in through overpickling then rolling and under " substantially " Restoration stage heating the torrid zone for be good it is also possible to
For desired optimal thermal cycle by the boundary alignment of temperature aspect between Restoration stage and recrystallization stage, or even with master
Between the recrystallization stage wanted, until even and the crystal grain long megastage between.In other words in this case it is still possible to " recovery " band in one
Portion of material, and under given interval, make this part experience the beginning of recrystallization, even if recovery process not yet completes
Other partly the going up when continuing of the carrying material of Restoration stage is also such.Recrystallization stage and the crystal grain long megastage it
Between it is observed that the border of same type.In document " Traitements thermiques des alliages ferreux
（The heat treatment of ferroalloy）" in, the 68-71 page, extract " les pr é cis AFNOR/NATHAN-METALLURGIE（é
laboration, structures-propriétés, normalisation）", 2005 editions, ISBN AFNOR: 978-2-
12-260131-0, clearly illustrates for cold rolling these heat effects in the case of annealing（At least include the recovery rank carrying
Section and partially or completely recrystallize stage, practically even also crystal grain long megastage）.
The change of resume speed also depends on the thermokineticss of process, depends on：
The work-hardening capacity that the mill operation implemented in stove upstream produces.The degree that known rolling thickness reduces is bigger,
The discontinuous defect then being caused by the thickness reduction rolling in the crystal structure tissue of handled carrying material is more, corresponds to
More or less of energy accumulation in the structural material of handled band.This energy is in during annealing and especially in recovery
Period discharges；It should be noted that the dynamic work-hardening capacity depending on rolling generation that this of crystal structure changes；
Furnace temperature；
The duration of heat.
After these last aspects of potential annealing, the present invention proposes therefore to be likely to be of according to the equipment of the present invention
At least one section of stove is included for heating（And/or be used for cooling down）The mechanism of band, it guaranteed typically less than two minute phase
Between will become minimum temperature higher than at least part of recrystallization in the structural material of handled band with temperature control（Ideally
Higher than 500 DEG C）, rolling device presents（Band）More than 5%, practically even up at least 40% significantly（Thickness）
Reduce.
Similarly, the equipment according to the present invention includes at least being used for heating therefore, it is possible to a section with stove（And/or
For cooling down）The mechanism of band, its guarantee during typically less than two minutes by with temperature control become higher than band at least partly again
Crystallization and/or the minimum temperature grown up until crystal grain（Ideally it is higher than 500 DEG C）, rolling device embodies（Band）More than 5%,
Practically even up at least 40% significantly（Thickness）Reduce.
For reference, recrystallization temperature value is typically located between 500 DEG C and 850 DEG C, and related to crystal grain temperature of growing up
The value of connection is higher, can reach and more than 900 DEG C.
It should be pointed out that realizing temperature control according to being directed to（For example control at least one thermal cycle（Restoration stage, Yi Jiran
Afterwards if necessary, recrystallization the stage, the crystal grain long megastage））The heating recommended of purpose（And/or cooling）Mechanism, in stove
Dispose radiating element（For example manage）And/or induction apparatuss.Generally more expensive than using radiating element using induction apparatuss, especially in energy consumption
Aspect.Therefore, it is noted that the rolling device in pickling unit exit in the case of setting radiating element in stove（Example
As skin pass rolling device）So that being especially possible to repair（Increase）The surface roughness of the band through rolling, i.e. surface roughness changes
The emission ratio of variable speed is not that is to say, that being in is that the band of very coarse apparent condition is easier to pass back by radiation heat emission
The heat radiation that device is launched, and contrary, and if surface is coarse, band is preferably absorbed radiated heat.Former for this
Cause, the rolling device of therefore stove upstream makes it possible to optimize（Practically even shorten）The desired thermal cycle of the present invention.
