Definitions

  • the present invention relates to a device and method for flattening metal product strip or plate type respectively preambles of claims 1 and 9.
  • hot and cold rolling plants including planing or pre-planing, for example of the "Steckel mill” type (hot-reversing mill) or “Plate Mill” (sheet metal rolling mill), or even a section of roughing a hot strip mill type of installation
  • products plates or strips whose criteria of thickness, flatness, hardening or other mechanical properties are very variable are more or less hovering, if at all.
  • planing is not to be done, a first method would be to lift the upper cassette to leave pass the product without leveling and use the lower cassette as a simple roller table to support the product as it passes. Therefore, the leveling rollers of the lower cassette are not very suitable for the simple function of rolling product support and very expensive. It must therefore be avoided that they suffer harmful damage to the good quality of planing.
  • the simple running speed of the product on the lower cassette would generally be and much higher than the planing speed of a product (for example five times higher) and this difference in speeds would also cause overheating or overheating. blows and therefore marks of the product on the planing rollers, implying an obvious degradation of the surface condition of said rollers, and therefore detrimental to the quality of the planed product, forcing premature and therefore expensive changes in said rolls.
  • An object of the present invention is to provide a metal product leveling installation temporarily to inhibit - and for example to replace by at least one product support rolling - a feature or a planing step for at least one product of a sequence of products in scrolling, without damaging the planing installation and reversibly to restore a functionality or planing step for another subsequent product. It is also envisaged to go from a planing functionality to an inhibited leveling functionality (for example rolling support) or vice versa for the same product during a series of passes of the same product in said installation.
  • planing inhibition and a feature replacement for example by at least one product support by rolling
  • This duration is estimated at most at a time interval between the tail start time of a first product at the exit of the leveling plant (under active leveling mode) and the arrival time of the head of a second product subsequent to the entry of the installation (in inhibited planing mode).
  • Another aim is finally, instead of the leveling step, to be able to introduce at least one other functional step associated with the metallurgical process of the line, different from the step of simply supporting the product by rolling given here as an example.
  • a set of subclaims also has advantages of the invention.
  • Figure 1 presents a first general view of the leveling installation according to the invention, upstream side with respect to the direction or axis D of scrolling of a metal product (PM) of active planing mode.
  • the scrolling can also be reversible, which is formalized by the two-way arrow, referenced by the axis (D).
  • the same leveling installation can be considered with an upstream side of the scrolling situated on the opposite side compared to the representation of the figure 1 .
  • the step of passing an active mode of the leveling installation to switch the leveling installation to an inhibited leveling mode is also carried out so as to allow a mode of operation related to the replacement tool (here an OR roller table used to support the product by rolling).
  • the solidarized unit in active leveling mode is advantageously kept in solidarized form until the inhibited leveling mode (and vice versa), that is to say that it is free of any decoupling of the drive means and of their respective cassettes, as well as any decoupling of any other means necessary for the operation of the leveling installation and its components such as signal connections and / or supply of energy and distributed fluids or gases of said components.
  • the lower and upper drive means (motors, gearboxes, extensions, connectors, etc.) and the leveling rollers of the upper and lower cassettes remain coupled together, and the other connection means (connections of signals or / and power) necessary for the operation of the leveling installation also remain connected together during the passage of a mode active to an inhibited mode and vice versa.
  • This allows a considerable time saving compared to a solution requiring decoupling or other spacing of cassettes from its drive means and connections to replace at least the lower cassette by the replacement tool.
  • the replacement tool may advantageously comprise a large variety of tools (alone or in combination) such as: a roller table or measuring means or an inspection means or a cutting means, or a maintenance means, or cleaning means, or pickling means, or surface treatment means.
  • a horizontal roller table conveying the product along the axis of scrolling as a tool replacement (OR) in the operator-side standby position.
  • the said roller table is advantageously equipped with intrinsic means for rotating its rollers, which makes it possible to increase at will the speed of passage of a subsequent product (non-planar, in inhibited mode of planing), and therefore to prevent any damage to the leveling rollers of the lower cassette if the product had to pass over it.
  • the moving means may simply comprise a carriage (such as a rolling or sliding structure) commonly coupled to the lower drive means and to the lower cassette, said carriage coupling making it possible to advantageously maintain the set of lower feed means. training connected to the lower cassette during the transition from the active leveling mode to the inhibited leveling mode and vice versa.
  • a carriage such as a rolling or sliding structure
  • the replacement tool (such as the roller table shown) is routed and disposed on the operator side (CO) facing the frame B by means of a known multi-position lateral positioning system (Pos) such that that sometimes already exists advantageously to perform a removal cassettes for quick exchange with another operating set of cassettes.
  • the replacement tool is then simply stowed to the lower cassette in order to be able to follow the same movements (transverse to the scroll axis D) as said cassette when activating said movements forward / back governed by the means of displacements (MD).
  • Figure 2 presents a second view of the leveling installation according to the invention (as figure 1 ), upstream side, in active leveling mode.
  • the lower and upper entrainment means (Me1, Me2) previously described in figure 1 comprise at least one motor (M1, M2), optional reducing modules (R1, R2) and elongations (A1, A2) respectively connected to the lower and upper cassette leveling rollers by means of connectors (Co1, Co2).
  • These connectors are generally integral with the extensions, such as sleeves, but are here specified to describe the invention more clearly.
  • An extraction means (V1) of the two lower and upper cassettes towards the operator side (CO) is embedded on the carriage (MD), so that the two cassettes can be extracted from the frame (B) for example for a conventional operation of maintenance.
  • This extraction means coupled to the lower cassette remains simply in the retracted position when changing from the active mode of planing to the inhibited leveling mode, said retracted position favoring a protection of the internal piston rod against external pollution during the two active modes and inhibited planing.
  • the planing rollers of the lower cassette ( C1) can very advantageously remain housed in the connectors (Co1) of the extensions (A1), the said extensions remaining integral with at least one optional reduction module (R1) connected to at least the motor (M1), thus avoiding disassembly of these elements, then especially avoiding finally a long reassembly for the return to the active mode of planing.
  • the optional reducer module (R1) shown is given by way of example, and could be eliminated or replaced by a reduction, multiplier or simple gearbox form.
  • the carriage as a simple and fast moving means embeds the secured assembly comprising the lower cassette (C1) , the extensions (A1) and their connectors (Co1), the optional gearbox (R1) and the motor (M1). Since the planing roller drive extensions are thus never decoupled from said rollers, the duration of the change of the lower cassette by the replacement tool is therefore mainly dependent only on the speed of the moving means (MD). Depending on the dynamic performance of the moving means (MD), it is therefore technologically possible to reduce the duration of the change cycle according to the required requirements such as the distance and speed between a tail of a product and a head of a subsequent product.
  • the upper training means (Me2) of the figure 1 is detailed in figure 2 and includes connectors (Co2) to rolls of the upper cassette (C2), said connectors being connected to the extensions (A2), themselves driven by at least one optional module (R2) linked to at least one motor (M2).
  • the optional reducer module (R2) shown is given by way of example, and could be eliminated or replaced by a reduction, multiplier or simple gearbox form.
  • Said upper drive means (Me2) is sufficiently raised relative to the lower drive means (Me1), for example placing it on or above a bridge (P) fixed to the ground (S), so that the lower drive means (Me1) passes under said bridge during a change of the lower cassette (C1) by the replacement tool (OR) and vice versa.
  • this means of motorization coupled to the lower cassette simply remains in the retracted position during an active planing mode, said retracted position favoring a protection of the inner rod of the cylinder against external pollution during planing.
  • Figure 4 has a fourth view upstream side of the leveling installation according to the invention such that Figures 1 to 3 , in inhibited leveling mode, that is, once the lower cassette (C1) has been moved to the motor side (CM).
  • the replacement tool (OR) such as the roller table shown in this example was then also driven by the lower cassette to take its place.
  • Figure 5 finally presents a fifth view of the leveling installation according to the invention according to one of the Figures 1 to 4 , in inhibited planing mode as in figure 4 but downstream side.
  • the lower and upper training means (Me1, Me2) according to figure 1 and their means of supply (CON) according to figure 4 are more explicitly represented or detailed.
  • the solidarized assembly grouping in series the motor (M1), the optional reducer module (R1), the extensions (A1) and their connectors (Co1), the lower cassette (C1) to which is stowed (by AR coupling ) the replacement tool (OR) are all coupled to the flexible connection means (CON) along a stroke of the moving means (MD) defined by its positioning between the two modes of active and inhibited planarization.
  • figure 6 has a sixth upstream side view of the leveling installation according to the invention, in Inhibited planing, comprising a single motor (M3) and an extension (A3) connecting the motor (M3) to the optional reduction modules (R1, R2).
  • M3 single motor
  • A3 extension
  • R1, R2 optional reduction modules
  • Figure 6 thus has a first secured assembly comprising the lower cassette (C1) and the lower drive means, said lower drive means comprising the single motor (M3), an extension (A3) connecting the motor to an optional module of reduction (R1), said optional module being coupled to the extension (A1) connected to the leveling roller of the lower cassette (C1).
  • the extension (A3) drives the two optional lower and upper reduction modules (R1, R2).
  • the lower reduction module (R1) is however free axially on the extension (A3), the extension (A3) being fixed relative to the ground (S).
  • the upper reduction module (R2) is fixed relative to the ground (S) (for example on a bridge P).
  • Figure 7 presents a seventh upstream side view of a planing installation alternative according to the figure 6 , in inhibited planing mode, comprising the single motor (M3).
  • the motor (M3) and its extension (A3) are embedded on the moving means (MD).
  • the extension (A3) drives the two optional lower and upper reduction modules (R1, R2).
  • the lower reduction module (R1) is movable with the extension (A3) relative to the ground (S), these two elements being movable on the moving means (MD).
  • the upper reduction module (R2) is fixed relative to the ground (S) (for example on a bridge P), but the elongate (A3) is axially free with respect to said reduction module (R2).
  • the method according to the invention can also provide that a first product undergoes the first pass and a second product distinct from the first undergoes the second pass.
  • the functional step of said method according to the invention can thus in a very varied manner be at least one of the following steps: a support step by product rolling or a measurement step or an inspection step or a cutting step , or a maintenance step, or a cleaning step, or a pickling step or a surface treatment step.
  • the complete replacement step is performed under a time less than a time interval between the product start time outside the leveling installation and the product arrival time in the installation. This is the case for a single product undergoing both first and second passes above.
  • the method according to the invention provides for a more that the complete replacement step is performed within a period of less than a time interval between the tail start time of the first product at the exit of the leveling plant and the arrival time of the second product. at the entrance to the facility.
  • the time interval is, as an indication, less than a few minutes, and ideally less than one minute.
  • the duration times indicated above can be of the same order in the case of treatment of two different products or the same product passing successively in the installation active or inhibited planing mode and vice versa.
  • the method according to the invention provides that the replacement step is reversible in order to return the lower cassette in the frame, instead of the replacement tool. It is therefore possible to switch from an active leveling pass to an inhibited leveling pass (and activated tool) and vice versa for any sequence of passes.
  • the successive reversible stages are identically always fast, because they are free of any decoupling of the integral whole and related connections.
  • the method according to the invention can provide that a small vertical spacing of the upper and lower cassettes is established at the start of the activation at the beginning of replacement of the lower cassette by replacement tool.
  • this spacing can be initiated in a little significant time preceding activation of the displacement means (MD), or even in a sequence inscribed in masked time with respect to said activation of the activation. moving means (MD).
  • the activation of the displacement means may furthermore necessitate a said displacement of translation (by jack V2 for example according to figure 3 ), an unlocking action of certain functions related to leveling elements (for example an unlocking of clamage or other), but this type of action is of second order duration.
  • a said displacement of translation by jack V2 for example according to figure 3
  • an unlocking action of certain functions related to leveling elements for example an unlocking of clamage or other
  • this type of action is of second order duration.
  • the weight of the elements to be moved may be more important than it advantageously does not require the use of clamping.
