Definitions
- the subject of the invention is a method for managing the entry of a new coil into a continuous line processing installation for a strip product and also covers an improved processing installation for implementing the process.
- the strip to be treated fed in the form of reels placed one after the other on an unwinder, passes successively through the various sections of the installation.
- To carry out the treatment continuously it is therefore necessary, at the end of the unwinding of a reel, to fix the tail thereof, that is to say its downstream end in the direction of travel, on the head of the next reel, i.e. the upstream end in the direction of travel.
- This junction which must be able to withstand the forces applied to the strip during travel through the successive sections of the installation, is most often carried out by electrical welding, in particular in the case of steel strips.
- the two ends, respectively downstream and upstream of the two successive bands to be welded must be perfectly parallel and they are therefore sheared before welding by means which can be integrated into the welding equipment.
- the process of joining two consecutive strips therefore comprises, on the one hand, operations for preparing the ends of the two strips and, on the other hand, the joining operations themselves. All of the operations are carried out in successive stages in equipment which, generally, is grouped in an entry section of the installation associated, most often, with two unwinders carrying respectively, one the reel at the end of the other the new coil to be treated.
- the tail of the latter in an input shears then position the strip in the welding machine and proceed with shearing from its downstream end.
- the new strip is then introduced into the welding machine, positioned and sheared.
- the ends of the two strips are sheared at the same time in the welding machine, which, for this purpose, is associated with means for positioning and clamping the ends of the two strips to be welded and with shearing means for the two ends. along two perfectly parallel lines which are then brought together towards one another to carry out welding, in particular by sparking, by passing an electric current between the two strips to be welded.
- the equipment placed in the inlet section of the installation therefore performs a series of operations which can be divided into two successive cycles: firstly, a preparation cycle comprising the trimming of the tail of the first strip and its positioning in the welder, then the introduction of the next strip with trimming of its head and its positioning in the welder. Then, the actual joining cycle comprising the shearing of the ends of the two strips to form two parallel edges opposite, their bringing together and their welding and the finishing of the weld.
- such a line successively comprises an annealing furnace and a pickling installation for the removal of scale, which is most often made up of a series of tanks filled with acid in which the bandaged.
- a descaling device by shot blasting placed before the pickling tanks in order to promote chemical pickling.
- the normal speed of travel of the strip in acid tanks is generally very high and can go, for example, up to 400 m / min.
- the running of the strip must be stopped periodically, in the input section, to allow the operations of joining the tail of a reel with the head of the next reel.
- the installation ends with an outlet section comprising at least one reel of the reel tape.
- the rolled up length being obviously limited, it is necessary, at the end of the winding of a reel, to cut the end of this one and to engage the continuation of the strip on another reel to allow the evacuation of the reel wound.
- a continuous on-line processing installation in particular for the pickling of steel strips, successively comprises, in the direction of travel of the strip, an inlet section, an upstream accumulator, a section of treatment, a downstream accumulator and an output section, the upstream accumulators and the downstream accumulator each having an accumulation capacity corresponding at least to the length of strip running, at normal speed, in the treatment section, respectively during the time stop in the inlet section for the connection of the head of a new reel to the tail of the previous reel and during the downtime in the outlet section for the evacuation of the wound reel.
- connection between two consecutive strips requires a series of operations carried out by the various devices of the input section.
- FIG. 1 is a diagram indicating, on the abscissa, the times necessary for the successive stages of the general process of connection between the tail of a coil at the end of unwinding and the head of a new reel, these steps, referenced A to K, being, for example, the following:
- the stopping time can be of the order of 5 seconds as indicated in the diagram.
- - F Shearing of the ends opposite the two bands.
- the facing edges of the two successive bands must be straight and perfectly parallel, in particular for flash welding.
- a double shears allowing to realize at the same time, on both sides of the welding device, the shearing of the two edges opposite. This operation can therefore be rapid and require, for example, 5 seconds.
- - G Welding of the two opposite edges. This operation depends on the welding process but can take, on average, 15 seconds.
- the time required for finishing operations can be of the order of 10 seconds.
- the diagram in Figure 1 shows that the idle time from when you start to reduce speed until it returns to normal speed exceeds 1 minute.
- certain additional operations are possibly necessary in certain cases, for example, after welding, a step J of notching the ends of the welded part, which may take 10 seconds and a step K of annealing the weld which may require 40 seconds. These two stages can be carried out at the same time before the acceleration of the strip for the return to normal speed.
- the overall time during which the scrolling must be stopped in the input section can therefore range from 75 to 115 seconds.
- a first cycle P of preparation comprising stopping the scrolling, trimming the ends of the two strips and their positioning in the welding machine and which therefore corresponds to steps A to E and, thereafter, a second cycle S of actual joining, comprising the shearing of the two edges opposite the two strips, their welding , finishing the weld and returning to normal speed and which therefore corresponds to operations F to I with, possibly, steps J and K.
- the diagram in FIG. 1 is only an example and other operations could possibly be added to the joining process, but in all cases, the dead time for stopping the scrolling for joining the two bands remains between 1 minute and 1 minute 30.
- the normal running speed is quite high, for example of the order of 400 m / min, and must, as far as possible, remain substantially constant.
- the upstream accumulator must therefore have a capacity of between 400 and 600 meters so that the length of strip put in reserve feeds the treatment section during the downtime in the inlet section.
- a continuous line processing installation is provided in its input section, with means making it possible to make the connection between successive coils without stopping the running in the processing section. It is therefore possible to successively treat strips having different structural and dimensional characteristics, by welding them one after the other.
- the length of strip to be treated can also vary depending on requirements and, in practice, it often happens that one has to treat coils having a short length, for example from 300 to 400 meters.
- the upstream accumulator placed between the inlet section and the processing section must supply the processing section during a dead time of stoppage in the inlet section, the duration of which cannot be reduced below a certain limit because it results from a succession of functions whose elementary times are chained in sequences.
- the accumulator must be refilled to allow connection with the next coil and, for this, the new strip is scrolled in the inlet section, at a higher speed than the normal processing speed, for example 600 to 800 m / min.
- the new reel is very short, its tail can arrive in the entry section before the accumulator is completely filled and it is necessary, at this time, again to stop scrolling in the entry section to make the junction by supplying the treatment section from the accumulator. If it is possible to absorb the passage of a single short coil, on the other hand, the insufficient filling can accumulate if several short coils have to be treated successively.
- the present invention makes it possible to solve this problem by means of a new method and an improved installation which make it possible to considerably reduce the dead time of the input section and, thus, to incorporate coils of different sizes much more easily in the line.
- the invention makes it possible to increase the real speed of processing and, thus, the productivity of the line.
- the subject of the invention is therefore, in general, a method for managing the entry of a new coil into a continuous line processing installation for a strip product, supplied with successive coils and comprising means for controlling the continuous running of the strip, successively in an inlet section, an upstream accumulator, a processing section, a downstream accumulator and an outlet section, the connection of the tail of a first reel at the end of the unwinding with the head of a following reel being carried out in the entry section of the installation in two cycles of successive stages, respectively a first cycle of preparation of the ends, respectively tail and head of the two strips for their junction and a second actual junction cycle of the two edges opposite said ends.
- the junction of the edges facing the ends of the two strips is carried out in at least two parts of the inlet section, respectively a first part and a second part, between which is interposed an intermediate accumulator for reserving a variable length of strip and the time necessary for all the operations of connecting the two strips is divided into at least two periods, respectively a first period corresponding to the preparation cycle and to a first phase of the cycle junction of the edges facing the two bands and a second period corresponding to a second phase of the junction cycle, said two periods being separated by a time interval of variable duration corresponding to the scrolling in the intermediate accumulator of the length of band set aside.
- An essential idea of the invention therefore resides in the splitting of the joining cycle into two separate phases, with a variable length of strip being stored in an intermediate accumulator.
- the junction of the two strips is carried out by welding, in a welding machine placed in the first part of the inlet section.
- the welding operation is carried out at the end of the first period in a first phase of the joining cycle and the tail of the first strip is then passed through the intermediate accumulator and its junction welded with the head of the next strip, the running being stopped again in the second part of the input section to carry out at least one finishing operation during a second period of the joining cycle.
- the welding machine is placed in the second part of the inlet section.
- a provisional junction of the tail of the first strip is made with the head of the next strip, at the end of the first period of the general connection process, in a first phase of the joining cycle and we then resume the running of the strip to bring said provisional joining into the second part of the input section via the intermediate accumulator, the running being stopped again during the second period of the general process connection in order to carry out the actual welding operation and at least one finishing operation in a second phase of the joining cycle.
- the lengths of band corresponding to their maximum capacity are set aside in the upstream accumulator and in the intermediate accumulator.
- the method according to the invention thus makes it possible, during the first period of the joining process to supply the processing section at normal speed from the upstream accumulator, and at the same time, to pass through the upstream accumulator, from the intermediate accumulator, a length of strip capable of replacing at least part of the length passing through the treatment section.
- the invention also covers an improved installation for implementing the method, comprising, as usual, an inlet section, an upstream accumulator, a processing section, a downstream accumulator and an outlet section.
- the process of connecting the tail of a reel at the end of the unwinding with the head of a new reel is carried out in successive stages in different equipment which, sometimes, is grouped together in the same machine but can also be separated.
- the installation includes:
- each unwinder being associated with a trimmer shears
- positioning means for example lateral guides for entering the strip into the welder
- - finishing equipment for example a planing machine which can, if necessary, be integrated into the welding machine
- - Positioning means such as lateral guides for the exit of the strip and for example its entry into a tensioner preceding the upstream accumulator placed at the entry of the pickling section.
- the invention is based on the idea that it is possible to distribute the inlet section of equipment in two separate parts physically by an intermediate reservoir, so that the entire connection process is divided into two periods separated by a time interval of variable duration.
- This intermediate accumulator will have a capacity corresponding at least to the length of strip running in the processing section at normal speed for the duration of the first period of the connection process.
- this intermediate accumulator can supply the upstream accumulator so as to maintain the latter, as much as possible, at its maximum capacity. In this way, it is possible to give the upstream accumulator a capacity corresponding simply to the length of strip running in the processing section at normal speed during the second period of the connection process.
- the invention makes it possible, in particular, to solve the problem of relatively short coils. Indeed, it is possible to manage the rate of filling of the intermediate accumulator as a function of the length of each new coil so as to be able to restore the upstream accumulator to its maximum capacity after each period of the connection process.
- the speed of unwinding of the new coil for filling is increased, at least partially. , of the intermediate accumulator, so that, depending on the length of the new coil, the tail thereof can be stopped in the first part of the inlet section for its junction with the head of a third coil, after setting aside a strip length corresponding to at least the first period of the connection process.
- FIG. 1 is a diagram indicating, by way of example, the duration of the different stages of the general process of joining two successive bands.
- FIG. 2 schematically represents the inlet section of an installation, in a first embodiment of the invention.
- FIG. 3 is a diagram representing the progress, in time, of the two periods of the connection process.
- FIG. 4 schematically represents the inlet section of an installation, in a second embodiment of the invention.
- FIG. 5 is a diagram indicating, over time, the course of the two periods of the general connection process, in the embodiment of FIG. 4.
- FIG. 1 is a diagram representing, on the abscissa, the course over time of the various stages A to I of the general process of connection, carried out, in a conventional manner, in the entry section of a continuous line processing installation
- FIG. 2 schematically represents the inlet section of an improved installation according to the invention, in a first embodiment.
- the strip to be treated can be unwound from one or the other of two unwinders 11, 11 'each associated with means 12, 12' for unwinding and straightening the strip and with a shear. trimming 13, 13 '.
- a switching device 14 makes it possible to introduce into the entry section the strip M or M 'coming, respectively, from one or the other of the two unwinders 11, 11'.
- the inlet section 1 is divided into two parts 3 and 4 between which an intermediate accumulator 5 is interposed.
- the strip After its exit from the inlet section, the strip passes, as usual, into an upstream accumulator 6 then into the processing section 7, this being followed by a downstream accumulator and the outlet section.
- the parts of the installation which follow the upstream accumulator 6 are not modified and have therefore not been shown in the drawings.
- the equipment necessary for the junction of two successive coils is distributed between the two parts 3 and 4 of the input section 1.
- the first part 3 of the inlet section comprises a temporary joining means 31 such as a stapler, associated with lateral inlet 32 and outlet guides 33.
- the intermediate accumulator 5 can be produced in the usual way according to the length of strip to be set aside, this length being indicated below.
- a strip accumulator consists of a set of fixed rollers and a set of movable rollers on which the strip passes, the movable rollers being mounted on a carriage which can be move to vary the length of the accumulated tape.
- the strip must remain taut between the fixed and movable rollers and this is why such an accumulator must be associated, normally, with two tensioners, for example with S rollers, placed respectively upstream and downstream of the accumulator in the direction scroll.
- the intermediate accumulator 5 has been represented diagrammatically by a movable roller 51 and two tensioners respectively upstream 52 and downstream 53.
- the second part 4 of the inlet section 1 comprises, as usual, welding equipment 41, for example by sparking, associated with a double shear 42 and a planer 43.
- welding equipment 41 for example by sparking
- a double shear 42 for example by sparking
- a planer 43 for example by sparking
- these equipment have been shown separately but we know that they can advantageously be grouped in the same machine.
- French patent 2,756,504 of the same company describes a flash welding machine comprising two pairs of jaws for clamping the ends of the two strips M, M 'to be connected, which are respectively mounted on a fixed frame and on a movable frame, a double shear consisting for example of two pairs of blades or rollers movable transversely for shearing the ends of the two strips along two parallel lines and a planing tool mounted sliding transversely on the fixed frame.
- the welding machine is usually associated with lateral inlet 44 and outlet 45 guides which allow precise positioning, in the machine, of the two strips M, M ', in particular for shearing and the approximation of the ends to be welded.
- the upstream accumulator 6 can be produced in any known way and has therefore been shown diagrammatically in FIG. 2 by a simple movable roller 61 associated with two tensioners 62, 63.
- the installation shown in FIG. 2 therefore makes it possible to divide the connection process into two successive periods carried out respectively in the two parts 3 and 4 of the inlet section.
- the first section 3 of the installation differs from a conventional installation in that the electric welding machine is replaced by a temporary joining means such as a stapler 31.
- the first period of the process connection therefore comprises, on the one hand, steps A, B, C, D, E of the corresponding preparation cycle P, as explained above with reference to FIG. 1, to the cutting of the tail of the strip in progress, the introduction of the next strip previously cut and the positioning of the two strips in the stapler and, on the other hand, two new steps L and M.
- step L the two strips are stapled. This operation is faster than welding and can take, for example, 5 seconds.
- the overall time Ti for stopping the scrolling in the first part 3 of the input section can therefore be of the order of 50 seconds.
- the treatment section was supplied by the upstream accumulator 7 but, according to an essential characteristic of the invention, the latter was in turn supplied from the intermediate accumulator 5 so as to be maintained substantially at its maximum capacity.
- the capacity of the intermediate accumulator 5 must therefore correspond at least to the length of the band running at the normal processing speed during the first downtime " TV
- the tail of the first strip returned to its running speed is provisionally joined to the head of the new strip and therefore passes through the intermediate accumulator 5 to arrive in the second part 4 of the input section. Since, at this time, the intermediate accumulator 5 has a reduced capacity, the time T 2 for the temporary junction to run through this intermediate accumulator can be quite short, for example, 25 seconds.
- the provisional junction must, first of all, be positioned in the welding machine in a step E 'which may take 10 seconds.
- the ends of the two bands being held by the clamping jaws of the welding machine, in a step F ′, the two edges are sheared with the staple removed and their welding is carried out in a step G.
- Finishing operations are then carried out, such as planing the weld (step H) and then returning to normal speed (step I).
- This second period of the connection process requires an overall stop time T 3 in the second part 4 of the input section which can be of the order of 45 seconds.
- step J this time can be lengthened if notching (step J) and / or annealing of the solder (step K) is carried out.
- step I or K the running of the strip can resume at normal speed but the upstream accumulator 6 which supplied the processing section must be brought back to its maximum capacity.
- the scrolling speed in the input section 1 is increased, by example, up to 700 or 800 m / min for the time necessary to fill the accumulator.
- the scrolling must be stopped at the moment when the tail of this new reel arrives at. start of the input section 1 and, if the length of this new coil is too short, this moment may occur before the upstream accumulator 6 is completely filled.
- connection process makes it possible to avoid such a drawback by dividing the connection process into two periods carried out in two different parts 3, 4 of the input section 1 and separated by a time interval T 2 of variable duration.
- the overall stop time of the scrolling necessary for the connection of two successive bands is divided into two periods and, consequently, the time during which the treatment section 7 must be supplied by the upstream accumulator 6, is equal, either at the stop time Ti in the first part 3 of the input section, or at the stop time T 2 in the second part 4.
- the intermediate accumulator 5 can maintain the upstream accumulator 6 at its maximum capacity during the stop time T 1 in the first part 3 and can then be filled during the stop time T 3 in the second part 4 of the input section so as to be at its maximum capacity when the tail of the new strip arrives in the first part 3.
- the tail of the new coil integrated in the line arrives at the start of the input section 1 at an instant t *.
- This instant U is offset by a time T 4 with respect to the moment ti when the head of the new strip M 'had left the first part 3 of the input section 1, after its provisional junction with the tail of the previous strip M.
- This time T 4 therefore depends on the length of the new coil.
- an intermediate accumulator 5 it is possible to again stop the scrolling in the first part 3 to make the junction with a third coil, as soon as the intermediate accumulator 5 has sufficient capacity to maintain the scrolling downstream during the time T 1 .
- the speed of travel in the first part 3 can be increased to fill the intermediate accumulator 5.
- the time required this filling therefore corresponds to the minimum duration of the offset T 4 between the respective passages of the head and the tail of the new coil, which depends on the length of the latter.
- the junction with a third coil possibly begins even before time h, that is ie before the end of the second period T 3 of the connection process.
- the two periods can, in fact, overlap since they are carried out in two different parts of the input section 1 separated by the intermediate accumulator 5.
- the invention is not limited to the single embodiment which has just been described but may be subject to variants, for example for the distribution of the equipment between the two parts of the inlet section.
- the welding machine 41 is placed in the first part 3 of the inlet section 1, upstream of the intermediate accumulator 5. In this case, no provisional junction is not necessary and the stapler 31 of FIG. 2 is omitted, the tail of the strip M at the end of the unwinding being electrically welded to the head of the new strip M '.
- the welding machine 41 can be equipped with a double shear 42 making it possible to produce, on the ends of the two strips, two parallel edges which are then brought together for sparking.
- a preparation cycle P corresponding to steps A to E and a junction cycle divided into two phases separated by the passage through the intermediate accumulator 5, respectively a first phase Si corresponding in steps F, G, M and taking place in the first period of the process and a second phase S 2 corresponding to steps N, H, I and, optionally J and K.
- the overall duration T'i of this first period of the joining process is slightly greater than that of the first period in the case of the figure 3, and can be of the order of 60 to 65 seconds.
- the welded junction passes into the intermediate accumulator 5 and arrives in the second part 4 of the input section at an instant t'2, the passage time T 2 can be simply 20 or 25 seconds in the since, at this time, the intermediate accumulator 5 has a reduced capacity.
- step J a notching (step J) and an annealing (step K).
- the duration T 1 of the first welding period may be greater than the duration T 3 of the second planing period but is, in any case much less than the overall time previously required for the junction.
- the intermediate accumulator 5 makes it possible to replace, at least partially, the length of strip supplied by the upstream accumulator 6 during the time T 3 and, thus, to maintain the latter at its optimum capacity.
- the invention applies especially to continuous lines for pickling steel strips but could also be adapted to other treatments in continuous lines.
