Definitions

  • the present invention relates to a device intended for ensuring the storage of metallurgical products, such as in particular thin slabs, obtained from parallel continuous casting lines and delivered to a rolling mill system.
  • the invention more particularly proposes to provide a device for storing such metallurgical products to be installed downstream of two parallel continuous casting lines operating simultaneously and upstream of a system for transferring the products obtained to ensure a continuous supply of '' a rolling mill using products from either and alternately from each continuous casting line.
  • FIG. 1 of the appended drawings shows in perspective and schematically an installation which comprises two continuous casting lines 10, 10 ′ allowing d '' obtain metallurgical products such as thin slabs B, B ′.
  • Two shears 12, 12 ′ ensure the cutting of each slab to the desired length and, the slab thus produced, such that B or B ′ is brought respectively into an oven 16, 16 ′ by displacement on a roller table respectively 14, 14 ′.
  • Each of the ovens 16, 16 ′ is arranged along the corresponding casting axis and it provides an ideal homogeneous temperature of the slab for the subsequent rolling operation. Inside each of the ovens the slabs move on a system of rollers or rollers driven in rotation.
  • a transfer machine designated as a whole by the reference 18 which makes it possible to feed a rolling mill 20 to using successive slabs such as B ⁇ coming alternately from each continuous casting line 10, 10 ′.
  • the mobile support beams are divided into two identical series arranged in parallel in two locations of the storage area and a single series of transport beams is provided, each beam of said series being positioned between two pairs of support beams at a location in the storage area to ensure the movement of products from either of the continuous casting lines in said storage area.
  • each of the transport beams is divided into two independent parts which makes it possible to create two independent storage zones, each zone being supplied with products from the corresponding roller table.
  • the invention also relates to an application of the device for the storage and transfer of thin products coming from two continuous casting lines parallel to a rolling line, characterized in that the products enter the storage enclosure on one of the tables with rollers of the latter and emerge from this enclosure via the other roller table, the products being transferred between said roller tables by means of movable beams, these products being able to be stored in the storage area located between the two roller tables.
  • the device according to the present invention essentially comprises an enclosure heated in which is provided with a storage zone intended to receive the metallurgical products such as the thin slabs B, B ′ coming continuously from the two continuous casting lines such as 10, 10 ′.
  • This storage enclosure according to the invention can be installed either on the inlet side of the two ovens such as 16, 16 ′ ( Figure 1) or on the outlet side of these two ovens, immediately before the transfer device 18 making it possible to supply the laminating installation 20.
  • the storage enclosure according to the invention can be installed in any intermediate position.
  • this storage enclosure is in the form of an oven 22 having a length at least equal to the length of the metallurgical products to be stored.
  • This storage oven 22 has inlets such as 24, 24 ′ ensuring the introduction into the enclosure of the oven of products such as thin slabs from the continuous casting lines and it also includes outlets for these products, these these to be transferred to a rolling facility.
  • Thin slabs are transported inside the storage oven using support and drive rollers such as 26, 26, the rotation of these rollers being able to be ensured from outside the oven storage via a cantilevered shaft as shown in Figure 2.
  • mobile beams such as 28, 28 ′ and 30 are provided. These mobile beams and their movement are designed so as to move products such as thin slabs B, B ′ Inside the storage enclosure 22, parallel to their axis, from the two rows which correspond to the axes of the continuous casting installations such as 10, 10 ′ and to deposit them for storage in a storage area which is provided between the two lines of roller tables 26, 26 ′.
  • the mobile longitudinal members 28, 28 ′ constitute product support longitudinal members and the mobile longitudinal members such as 30 constitute beams for transporting products.
  • These support and transport beams can move vertically with respect to the roller lines 26, 26 ′ so as to pass from a maximum elevation position, in which the upper surface of the beams is at a higher level relative to the roller lines 26, 26 ′ at a minimum elevation position in which the upper surface of these beams is at a lower level compared to the roller lines.
  • the transport beams such as 30 are located at a certain distance from the support beams 28, as can be seen in FIG. 3 and they can lift relative to these support beams while also being able to move horizontally in order to make advance products step by step.
  • each metallurgical product such as the thin slabs B, B ′ corresponding to each row is selectively gripped by the relative movement of the support beams 28, 28 ′ and the transport beams 30
  • the mobile transport and support beams ensure the movement of waiting products in the storage area located between the roller tables 26, 26 ′, towards the normal operating circuit.
  • a storage capacity is thus produced which allows continuous casting to continue in the event of even prolonged stoppage of the work of the rolling line.
  • FIG. 4 schematically represents the installation during its normal operation, the thin slabs B, B ′ running continuously on the roller tables 26, 26 ′ situated in the enclosure of the storage oven 22 along the casting axes keep on going.
  • the mobile support beams 28, 28 ′ and transport 30 are located at a level -1, the level 0 being that of the upper plane of the rollers of the tables 26, 26 ′.
  • the horizontal displacement of the product such as B ′ can be obtained at one time or by the repetition of several identical rectangular cycles so as to bring the product to be stored in any desired location of the storage area located between the two tables roller 26, 26 ′.
  • FIG. 6 illustrates the manner in which the storage of product B is carried out.
  • Product B ′ is placed on the housings 28, 28 ′ at altitude level +2 so as to allow the product B transfer cycle to be carried out freely, product B ′ being thus placed out of reach for the various elements who move product B to the storage area.
  • the side members 28 firstly place the product B in the plane of the rollers 26 at level 0 then the side members 30 perform one or more rectangular cycles so as to bring the product B to the storage position.
  • This storage cycle for product B takes place in the same way as the storage cycle for product B ′ described above with reference to FIG. 5.
  • FIG. 7 represents the storage operation of products B and B ′ on the mobile beams 28, 28 ′ and 30 at level -1.
  • the rollers 26, 26 ′ are free and they can directly transfer other products such as B1, B′1, along each of the axes of the roller tables.
  • Products B and B ′ remain in the storage area and the vertical movements of the mobile support beams 28, 28 ′ and of transport 30 make it possible to vary the point of support of the product and consequently to limit the hot deformation of these as well as the formation of black marks.
  • FIG. 8 represents the taking of a second product B′1 on the roller table 26 ′.
  • This cycle will take place in the manner described above: we begin by ensuring the release of products B and B1 at level +2 so as to put them out of the reach of the mobile elements which are used to move products B ′ And B′1 towards the storage area, then the support beams 28 ′ are moved by lifting up to level 0, then a horizontal displacement of the two products B ′ and B′1 is carried out using the transport beams 30 which perform one or more rectangular cycles as described above. Products B ′ and B′1 were thus brought to two successive locations in the storage area. It is of course possible to perform a similar operation on the other side of the installation, that is to say on the side of the roller table 26, in order to move the products B and B1 towards the storage area.
  • FIG. 9 shows an example of the maximum storage capacity of eight products.
  • the storage area comprises two products three times B, B1, B2 and B ′, B′1, B′2 respectively, coming respectively from each of the lines of continuous casting and two products B3, B′3 waiting on the roller tables 26, 26 ′ of the storage oven according to the present invention.
  • the configuration can be that illustrated in FIG. 7, according to which two products B, B ′ have been positioned in the storage area, up to the configuration illustrated in FIG. 9 in which there are six products present in the storage area.
  • the mode of implementation of the invention for ensuring the evacuation of the products using the roller tables 26, 26 ′ will be identical.
  • the evacuation of the products begins with the products which are present on the roller tables 26, 26 ′, these products following the usual transfer cycle.
  • a roller table located next to the storage area is free, the stored products are placed, corresponding to the other continuous casting line, out of the reach of the moving elements used to ensure the evacuation of a product on said roller table, using the movable beams 28, 28 ′ and 30 so as to bring the products to be insulated to the level +2, as shown for example in FIG. 8 (left part).
  • the cycle opposite to that described above is then carried out during storage, in order to move and deposit the product to be removed on the roller table. This cycle is carried out by a lifting movement obtained using the support beams such as 28, 28 ′ and by a rectangular movement of the transport beams 30.
  • the product thus removed from storage is evacuated in the normal circuit as indicated above. This operation can take place in the same way for each subsequent product, present in the storage area until completely emptying this area and resume normal production, that is to say passing the products directly through the storage oven on the roller tables 26, 26 ′ towards the corresponding evacuation outlets.
  • This variant differs essentially from the embodiment described above with reference to Figures 4 to 9, in that the mobile transport beams are distributed in pairs 30, 30 ′ between the support beams 28, 28 ′.
  • This configuration allows storage of products such as B, B ′ from one or the other of the roller tables 26, 26 ′ arranged along the axis of the two continuous casting lines, this storage being carried out completely independently for the two lines.
  • two independent storage zones S1 and S2 are obtained, respectively receiving the products to be stored such as B, B ′ which come from the respective roller tables 26, 26 ′. It is thus possible to store a product in one of the zones while a product is being loaded on the rollers corresponding to the other storage zone.

  • the mobile beams 28 and 30 which correspond to the storage area S1 of the products brought in by the roller table 26, are kept stationary so as not to hinder the movement of the product B which is routed in a normal manner the rollers of the table 26.
  • the support beams 28 lift up to level 0 in the upper plane of the rollers 26 ′, then the transport beams 30 ′ are moved according to one or more rectangular cycles in the manner already described below above with reference to FIGS. 4 to 9, so as to bring the product B ′ into the storage position in the storage area S2.
  • FIG. 12 now shows the loading of product B in the storage area S1.
  • the product B ′ remains stationary in its storage area S2, the side members 28 ′ and 30 ′ not being moved.
  • the operation of the roller table 26 ′ makes it possible to convey a product B′1 in a normal manner through the storage oven.
  • a vertical displacement of the support beams 28, followed by one or more rectangular cycles of the transport beams 30 make it possible to bring the product B to the storage position, in the zone S1, as illustrated by figure 12.
  • FIG. 13 represents the situation after the loading of products B and B ′ in their respective storage area S1 and S2, the roller tables 26, 26 ′ ensuring a direct routing of products B1 and B′1 through the storage oven .
  • Figure 14 is a diagram similar to Figure 9 illustrating an example of maximum configuration of a storage of eight products.
