Definitions
- the subject of the invention is an installation for producing a metal strip coated with at least one protective layer.
- the metal strips are produced in several successive stages, first of all the preparation of a raw product, by casting in a mold or continuous casting, the forging and hot rolling of this product for obtaining a strip reel known as "hot” and, finally, cold rolling.
- the hot coil Before cold rolling, the hot coil generally undergoes a descaling operation, for example, by pickling or shot blasting.
- Cold rolling is normally carried out in several successive passes, either in two opposite directions on a reversible train, or on several rolling mill stands operating in tandem. Annealing treatment may also be necessary.
- the cold transformation ends, most often, with a finishing treatment by passage, for example, in a "Skin-Pass" rolling mill and a leveler, to obtain the desired surface quality and mechanical characteristics. .
- the strip must be coated with a protective layer which can be a metallic coating obtained, generally, by galvanization or, more simply, a coating by coating such as a paint.
- an installation modern can include, in a single line, a pickling section, a tandem rolling mill, an annealing oven and a work hardening cage.
- the different sections for example annealing, pickling and rolling operate at quite different speeds and can be subject to deceleration or even stops in the event of a breakdown or, simply, for maintenance. It is therefore necessary to interpose, between certain sections, accumulators which make it possible to continue the treatment in a section in the event of stopping or slowing down of the strip in a section placed upstream or else to accumulate the strip at the outlet of a processing section in case of downstream scrolling stop.
- the accumulators must have a capacity of several hundred meters.
- the strip forms a plurality of parallel strands along return journeys determined by a set of fixed rollers and a set of movable rollers placed on a looping carriage movable between two positions, of minimum accumulation and maximum accumulation respectively.
- the continuous line installations are therefore placed in very large buildings comprising one or more halls equipped with overhead cranes enabling the handling of the coils and / or the parts necessary for the maintenance of the various equipment.
- buildings cover a very large floor area and are very expensive.
- the laminated strip must often be coated, on at least one side, a protective layer, for example a metallic coating produced by galvanization or a paint.
- the metal strip first passes through a bath of liquid metal which is deposited, at the outlet, on each side of the strip, forming a metal layer whose thickness is controlled by a means d 'spinning. To ensure regularity of deposit, it is necessary that the strip circulates vertically at the exit of the bath. The deposited metal is then solidified by cooling. Generally, the strip therefore travels along a path comprising an ascending vertical branch which extends along a cooling device over a length sufficient for the metal to be sufficiently solidified to pass over a deflector roller and a descending branch along which continues the cooling of the strip.
- the coating can also be produced by coating, the strip running between rollers or paint spraying means.
- this equipment is placed in separate buildings, the cold-rolled coils being directed towards one or the other of the two coating lines according to the order book. This makes it possible to use equipment the production of which can be adapted to requirements, but the handling of the coils entails a risk of deterioration thereof and requires intermediate storage.
- the object of the invention is to solve these various problems by means of a versatile installation making it possible to group, in the same line, the equipment necessary for coatings of different types.
- the invention makes it possible to use this equipment, either alone or in combination with other equipment, for example to obtain the necessary surface quality or else to produce an additional coating.
- the invention therefore relates to an installation for producing a metal strip coated with at least one protective layer comprising means for controlling the running of the strip, successively, in a series of treatment sections placed one after the another in a continuous line.
- the installation comprises at least, in one direction of travel of the strip:
- a first metal-type coating section having two lateral sides perpendicular to a longitudinal direction of travel of the strip, respectively a first side and a second side, and comprising means for entering the strip into said metal coating section, placed at a low level on the first lateral side thereof and opening into a tank capable of being filled with a bath of liquid metal, means for guiding the strip along a first travel path comprising an immersion part penetrating into the tank for depositing metal on the strip, an ascending part extending in a substantially vertical direction between the exit from the tank and a high level and a descending part extending between said high level and an outlet means of said first coating section, placed at a low level on the second lateral side thereof, and cooling means arranged at least along the ascending part of said first running path for solidifying the metal deposited on the strip, - a second coating type coating section, placed next to the first section and having two lateral sides perpendicular to the running direction, respectively a first side extending along the second side of the metal coating section and a second
- An output section comprising at least one strip accumulator and winding means.
- the entire installation can be placed in a single building comprising a central tower having two adjoining parts in which are installed the two covering sections, respectively of metallic type and by coating and two more halls low height which extend on either side of said central tower and in which are installed, respectively, the supply section and the outlet section.
- these two halls each have a height and a length corresponding at least to the height and the length of an accumulator of corresponding capacity.
- the exit hall advantageously has a height determined so as to cover an exit accumulator, leaving below it a space of sufficient height to contain, on the one hand, a treatment section complementary to the strip s 'extending below a rear part of the accumulator and, on the other hand, at least means for winding the strip extending below a front part of the accumulator, the length of said hall being determined so as to leave, in front of the accumulator, a space necessary for placing therein a means of turning the strip and, possibly, inspection means.
- the second hall in which the feed section is placed advantageously has a height determined so as to cover the assembly with a superimposed inlet accumulator and annealing oven.
- the complementary treatment section which is placed on the strip path between the exit from the first metal coating section and the entry into the second coating coating section, comprises, for example, a "Skin-Pass" rolling mill placed between two tensioners and / or a powered leveler and / or an additional coating device such as chromating or phosphating.
- the means for entering the second coating coating section is placed on the second side thereof, opposite the first coating section and the strip then follows, between the two covering sections, an elbow connection path comprising a first horizontal branch passing, at a low level, below the second covering section, and on which a treatment section can be placed complementary, and a second horizontal branch returning back, at a median level, to the means of entry into the second covering section.
- the installation comprises means for selective commissioning of each treatment section making it possible to choose an operating mode suited to the needs from among a set of possibilities for combining said treatment sections, for example a first mode with metallic coating alone, a second mode with metallic coating and complementary treatment, a third mode with complementary treatment and coating by coating, a fourth mode with two combined coatings, metallic and by coating respectively, as well as an additional treatment comprising at least one " Skin-Pass ”and a fifth mode with coating by coating alone.
- an operating mode for example a first mode with metallic coating alone, a second mode with metallic coating and complementary treatment, a third mode with complementary treatment and coating by coating, a fourth mode with two combined coatings, metallic and by coating respectively, as well as an additional treatment comprising at least one " Skin-Pass ”and a fifth mode with coating by coating alone.
- an accumulator of the horizontal type comprising, in a known manner, a plurality of parallel strands along return paths, between which are interposed separating arms spaced from each other.
- the rear part of the accumulator lying between an average position of the looping carriage and its retracted position of minimum accumulation is devoid of separating arms, tensioners being placed upstream and downstream of the accumulator so as to maintain sufficient traction on the strip to avoid contact between the outward and return strands.
- only the rear part of the accumulator, without separating arms, is used in paint mode.
- FIG. 1 schematically represents the supply section of a continuous line installation according to the invention.
- FIG. 2 schematically represents two coating sections and the outlet section of the installation.
- Figure 3 is a detail view which schematically shows the central part of a building in which the installation is placed.
- FIGS. 1 and 2 the various members of an installation according to the invention are shown diagrammatically for the production of a metal strip with protective coating, which comprises, in the direction of travel of the strip, a section d supply A shown in FIG. 1, two coating sections B and C and an outlet section D shown in FIG. 2.
- the strip to be treated is normally in the form of coils and the feed section A therefore comprises unwinding means 1 comprising, as usual, two unwinders 11, 11 ', two shears 12, 12' and a welding device 13 which connects the tail of a reel to the head of the next reel so as to produce a continuous strip which runs in a longitudinal direction, following a path determined by a set of deflector rollers 2.
- Guide blocks 14 and tensioning devices 15 of known type are placed at the desired locations on this path to guarantee good scrolling and to drive the strip M while controlling the levels of traction required in the different sections of the installation.
- the continuous strip M thus formed passes through a cleaning-degreasing device 16, then through an accumulator 3 of the horizontal type, the capacity of which is provided, as a function of the time necessary for the unwinding of the coils and for the welding, to connect two successive coils without stopping the running of the strip in the rest of the installation.
- the strip arrives in a first section B of metallic type coating.
- this coating is produced by galvanization in a tank 40 filled with liquid metal inside which is placed a submerged deflector roller 21b.
- the strip M coming from the supply section A is deflected by a roller 21a to enter the bath 40 by passing over the submerged roller 21 and leaves the bath in a substantially vertical direction, so as to ensure the regular deposition of a metal layer on both sides.
- deflection rollers which define a path 4 for the strip running, comprising at least one vertical ascending part 41, a horizontal part 42 placed at a high level and a descending part 43.
- the ascending part 41 is equipped with a rapid cooling device 44 extending over a height such that the zinc deposited on the two faces of the strip is sufficiently solidified, at its exit, to pass without risk of creation of defect, on an upper roller 22b.
- the strip then rotates forward, follows a horizontal path 42 to a roller 22'b, then descends along the vertical path 43, to a lower deflector roller 23b placed at a low level of the section. Additional cooling devices 45, 45 ′ placed along this path make it possible to complete the cooling of the strip M to the desired temperature.
- the strip then rises to a guide block 46 for possible recentering, then descends to an exit roller 24b placed at the bottom of section B to follow a horizontal branch 47 passing below the equipment of the second section C of coating by coating up to a second deflector roller 24'b.
- the strip can then be directed towards the second coating section C but, before, it flows in a complementary treatment section 5 in which can be carried out finishing treatments intended, in particular, to obtain the desired surface quality and comprising, for example, a “Skin-Pass” rolling mill 51 and a planer under tension 52.
- Tensing devices 54 make it possible to determine the levels of tension desired in each of these pieces of equipment.
- this complementary treatment section 5 is preferably placed at the lower level of the installation, in line with the horizontal branch 47.
- the strip turns over a pair of deflector rollers 21 d, 21 'd to return, at a median level, to the second coating section C passing over the complementary treatment section 5, along a horizontal return branch 55.
- This folded configuration of the complementary treatment section 5 makes it possible to add to it, at the end, additional coating equipment 53 making it possible, for example, to chromate or phosphatize.
- the strip then enters the coating section C by passing over a deflector roller 21c and then descends to a low level defined by a deflector roller 22c and a guide block 22 '.
- the coating by coating can be carried out, in the second section C, along a travel path 6 defined by a set of deflection rollers and comprising at least one vertical path along which are placed at least one coating device and a quick drying device.
- the travel path 6 can be folded so as to distribute the equipment in two nested columns.
- the strip can pass in front of a first coating device 61 to receive a first layer of surface preparation, which is dried in an oven vertical 62, for example a gas oven. Then the strip turns over on a high roller 23c and descends to a roller 25c and a refocusing means 25'c placed at the low level of the section.
- a tensioning device 24c makes it possible to ensure the drive under tension of the strip. This then passes in front of a second coating device 63 which applies the layer of paint, then rises in a drying oven 64 operating, for example, by induction, up to a high roller 26c. Each oven 62, 64 extends vertically over a height such that the applied layer is sufficiently dried so as not to be damaged by passing over the deflection roller 23c, 26c, placed at the outlet of the vertical oven.
- the running path 6 then returns forward, by a horizontal branch 65 extending between two rollers 26c, 27c and on which can be placed a cooling device to lower the temperature of the strip to the desired level.
- the strip then descends to a deflector roller 28c for exit from the second coating section C, which is placed at a median level, slightly above the entry roller 21c.
- the scrolling path 6 in the second section C thus comprises two nested columns making it possible to apply two superposed layers of paint on the strip without significantly increasing the size of the section C.
- the second device coating 63 is preferably made up of two groups of superimposed rollers which work alternately so as to limit the downtime necessary for the maintenance of this equipment.
- each covering section B, C therefore fits into a rectangular block having two vertical lateral sides perpendicular to the general horizontal direction of travel of the strip and the height of which depends on the time required, on the one hand for the solidification of the zinc and, on the other hand, when the paint dries, taking into account the speed of travel.
- two coats of paint it is possible, as mentioned above, to reduce the height of the section by folding the scroll path into two parallel columns.
- the strip M enters the lower part of the rear lateral side B1 of the galvanizing section B, exits at the lower part on the front side B2, passes below the coating section C towards the complementary treatment section 5 and returns back through the horizontal branch 55 to enter, in section C at a median level on the front side side C2 of it.
- the strip then passes successively through the first coating column 61, 62, inside the section, then into the I
- the second column 63, 64, along the rear side C1 goes back above the first by the horizontal branch 65, and descends along the front side side C2 to come out at a median level thereof, above the 'Entrance.
- the two covering sections B, C are thus arranged in two vertical blocks which are joined by their lateral sides, respectively front B2 and rear C1. This allows for a particularly compact installation.
- the strip M After leaving the second covering section C, the strip M enters an outlet accumulator 7 of the horizontal type comprising, in a manner known per se, two sets of looping rollers, respectively a fixed set 71 placed on the rear, at side of the coating section C and near the output roller 27c, and a movable assembly 72 placed forwards on a carriage not shown which can move horizontally under the action of a control means such as a winch 73.
- the loop rollers 71, 72 thus define a zigzag path of the strip comprising a plurality of strands which travel respectively, in a forward direction and in a backward direction.
- the accumulator 7 comprises several sets of separating arms 74 which are rotatably mounted around vertical axes, on either side of the strip and whose engagement and disengagement are controlled by the passage of the looping carriage, respectively towards the front and towards the rear.
- the carriage 72 moves forward under the action of the control means 73 passing between the sets of arms 74 which are open. After the carriage 72 has passed through each set of arms, they close so as to come between the different strands of the strip to avoid their contact.
- each set of separating arms opens just before the passage of the carriage 72 when the latter goes back to reduce the accumulated length. All these provisions are well known and do not require a more detailed description.
- the accumulator 7 does not include separating arms 74 in its first part 7a.
- the complementary treatment section 5 and the branch 55 for returning the strip to section C can advantageously be placed below a rear part of the horizontal accumulator 7, which makes it possible to reduce the overall size of the installation.
- the metal strip M enters the accumulator 7 in the middle of the height thereof, follows a zigzag course passing successively over the rollers of the looping assemblies 72a, 72b and exits, at the top of the 'accumulator, by a horizontal strand 70 which runs forward, that is to the left of the figure.
- the strip then reaches winding means 50 which are preferably placed below the front part of the accumulator 7, the strip being turned over on a pair of deflector rollers 76, 76 'placed in front of the winch. 73.
- These winding means 50 comprise, as usual, two winders 50, 50 ′ operating alternately thanks to a switching system and a shear 56 placed upstream as well as, optionally, an oiling device 57.
- the block downstream tensioner 75 ' the purpose of which is to keep the strip under tension in the accumulator, is advantageously placed below the latter, downstream of the lower deflector roller 76'.
- an inspection device 77 can advantageously be placed on the vertical path of the strip, between the two deflector rollers 76, 76 ′ turning backwards.
- the arrangement according to the invention makes it possible to produce a particularly compact installation comprising a central part in which are grouped the two adjoining covering sections B, C and two lateral parts, respectively of supply A and of exit D.
- each treatment section of the installation is associated with means for selective commissioning of the equipment which can thus either carry out the planned treatment or simply be crossed by the moving strip, without processing it. In this way, without modifying the constitution of the line, it is possible to choose different operating modes from a set of possibilities, by putting certain equipment into service, individually or in combination.
- the coating systems 61, 62 and 63, 64 are not put into service, section C being simply crossed by the strip running.
- the galvanizing section B is neutralized, for example by lifting the deflector roller 21b above the metal bath.
- the strip then simply follows the running path 4 in the first section B, before entering the complementary processing section 5.
- the equipment of the additional treatment section 5 can be used, or not, depending on the characteristics of the sheet and the desired surface quality.
- the two coating sections can also be used simultaneously to apply paint to the galvanized faces of the strip.
- the reversal towards the rear of the strip, at the end of the output accumulator 7, makes it possible to place an inspection device 77, for example by mirrors. Such an inspection is particularly useful in the case where a simple galvanizing is carried out, but it requires fairly frequent stops.
- the output accumulator 7 will therefore be sized according to this use.
- the invention therefore makes it possible to carry out a versatile installation, making it possible to place all the necessary equipment in a continuous line and to use it selectively, according to various combinations, as required.
- the invention is not limited to the details of the embodiment which has just been described by way of simple example, such an installation possibly comprising a greater or lesser number of equipment of all kinds.
- the supply section A could include, simply, an unwinder associated with preheating means making it possible to bring the strip to the desired temperature before entering the bath. galvanizing.
