Definitions
- the present invention relates to an installation and method for rolling a metal strip according to the preamble of claim 1.
- the metal strip rolling mills in particular cold-formed and capable of rolling strips mainly made of stainless steel, requires the use of a high-capacity mill (> 400,000 tons per year) such as a tandem mill.
- the rolling is carried out continuously (i.e., the web is continuously moving) to limit the costly loss of time and material during the introduction and release of web (such as for a discontinuous mill.
- upstream of the rolling mill the use of a welder makes it possible to connect successive tails and band heads together in a unwinding section made by at least one uncoiling machine Downstream of the rolling mill or at least at the end of a complete rolling line it is finally required to separate these strips to wind them into separate coils by means of at least one winder.
- the surface condition of the web is a critical component of web quality through a complete lamination line, so frequent visual inspections are most often required.
- Rolling plants such as those of the tandem type (adapted for carbon and stainless steel strips) are preferably equipped with double coils, placed at the downstream outlet of the rolling mill) and downstream of a shear for cutting the strip preferentially to the fly and separate it by forming disjoining bands to wind them alternately on preferentially two mandrels exerting on the belt upstream of the winding a specific traction to the conditions required for a good winding, a good bobbin behavior once output of the winding mandrel and the subsequent unwinding constraints on multiple lines of operation downstream of the operation rolling.
- the strip tension required for the winding is generally different from that required by the rolling operation: the strip tension associated with the rolling is generally greater or even much greater than the strip tension necessary for the winding, during the cutting and the transfer of the roll.
- the head of a belt to its winding machine traction is generally established or permitted only by means of a traction unit such as a nipper capable of establishing a lower pull than the desired web tension rolling mill output for good rolling conditions, which can induce a disruption of the strip thickness and a generation of final product out of tolerance to be downgraded and often not usable, which is very expensive especially in the case of production of lamination. 'stainless steel.
- the mill roll speed at the output of the rolling mill must be reduced during operations downstream of the rolling mill outlet, especially during cutting of the strip (shearing, beginning of winding on a mandrel, introduction of paper tape between turns of coil in stainless steel production, inspection, etc.), which induces a significant loss of productivity and also a qualitative impact on the factors of the rolling process, which generate defects in the thickness and flatness of the outgoing band of the rolling and in general all degraded qualitative factors well known by the effect of transient regimes of variations in speed and / or low speed.
- the present invention also provides for consideration of lubrication and internal cooling means on the rolling mill (on rolls of rolling mill and thus on the strip) in order to guarantee a predefined ratio of rolling, crushing and sliding of the rolling mill. band between the rollers under the contact arc strips on rolling rolls.
- these make it possible to obtain a lubrication / cooling rate that is useful for rolling in the rolling mill so as, on the one hand, to cool the rolled strip and on the other hand to make it possible to reach under good conditions and under the rolling force, a desired ratio between the rolling, crushing and sliding of the strip running in the rolling mill.
- the strip At the outlet of the rolling mill, the strip has a surface retention, residual rolling agents such as traces of oil and other elements of coolant of the rolls and tape used for the rolling process, as well as fats coming from various possible contributions. Due to the presence of oil, other grease or other on the strip, it can not be easily exerted on the strip at the output of the rolling mill, a significantly strong tensile stress, for good rolling conditions.
- the traction being generated by a traction unit at the output of the rolling mill such as tensioning rollers and / or roller clamping means, these traction elements are necessarily coated by accumulation of oil, other grease or other residual , which inevitably reduces the coefficient of friction and adhesions necessary to exert traction on the band.
- An object of the present invention is to propose an installation and a method of rolling a high productivity metal strip, by guaranteeing an increased control of band running characteristics independently of the operations made at the rolling output and especially from at least one traction unit downstream of a rolling mill to a final winding downstream of the traction unit.
- the installation according to the invention should in particular allow better productivity for a predominantly stainless type strip.
- a set of subclaims also has advantages of the invention.
- FIG. 1 An exemplary embodiment of the installation and application of the method according to the invention is provided using the figure 1 and its description below. An output variant of said installation of the same embodiment is also presented in figure 2 .
- the strip has an increased adhesion and therefore a better controlled trajectory when it passes over deflection rollers and at the inlet of each of the traction units (9, 9 '), an accumulator (10) downstream of at least a portion (9) of the traction units (9, 9 ') and other installations downstream of the rolling mill.
- Deviations, in particular lateral deflections, of strip paths are thus avoided, because an increased mastery of tape running characteristics is therefore achieved independently of the operations made at the rolling output and especially since at least the first traction unit (9 ) downstream of the rolling mill to a final winding (13, 14) downstream of the traction unit.
- the traction unit (9, 9 ') may comprise only tensioning rollers of the moving web for exerting a majority tensile tension, in particular said unit possibly being able to comprise only a pinching means for exerting an auxiliary tension. minority or even nil. As a result, there are fewer band defects incidentally induced by pinching means, hence higher productivity and quality.
- the installation according to the invention provides a control module of the degreasing unit that can be controlled by parameters of the installation and the physical properties of the moving strip, such as at least one lubrication rate imposed on the rolling mill. (7) and a maximum band rolling factor guaranteed by the traction unit (9, 9 ').
- This control system thus allows a more refined optimization of adjustment of the depollution module in order to achieve a more economical depollution in terms of the use of degreasing products or other depolluting agents while ensuring an optimal depollution (therefore environmentally desirable) to achieve better control of traction and trajectory of band and a higher productivity.
- the installation according to the invention comprises successively from its main inlet and upstream of the rolling mill, at least one uncoiler (1, 2), a welder (4), an accumulator (6), at least one traction unit (5, 5 ').
- these coupled elements allow high speeds of travel upstream of the rolling mill, knowing that the invention makes it possible to increase the running speed of rolling with increased productivity, because of better control of the strip path downstream of the rolling mill. rolling mill.
- the installation according to the invention may comprise downstream of the traction unit (9, 9 ') at least one so-called APL type line (derived from the "Annealing Pickling Line” in English, as well as other types underlining CAPL "Cold Annealing Pickling Line” is directly coupled in scrolling
- APL type line derived from the "Annealing Pickling Line” in English, as well as other types underlining CAPL "Cold Annealing Pickling Line” is directly coupled in scrolling
- Continuous strip is coupled via at least one coiler downstream of the traction unit to a CAPL line-entry uncoiler.
- a direct coupling has a disadvantage of speed of scrolling, because line CAPL imposes tape running speeds much lower than those reached by the installation according to the invention.
- this method allows inspection (11) and shearing (12) which are performed during the second step while the tape running speed is reduced.
- the method according to the invention allows a paper sheet insertion on the tape also initiated during the second step while the tape speed is reduced.
