Definitions

  • the present invention relates to a device for the treatment of steel products within metallurgical enclosures. It aims more precisely a transfer device allowing the charging in furnaces for reheating steel products such as billets, blooms, slabs, drafts, from a production site located upstream, from type in particular of a continuous casting, a rolling mill, or a fleet of storage, before their use in a production site located downstream, particularly a train of hot rolling mills.
  • Another aspect of the invention also consists in an installation of metallurgical treatment of steel products, in which the geographic location of a first so-called preheating chamber and a second so-called reheating chamber, is optimized due to the use of the transfer device according to the other aspect of the invention.
  • the hot products are placed in the a reheating chamber.
  • cold products they are introduced in a preheating oven which brings them to product temperature hot, before being transferred and placed in the oven with hot products.
  • the hot products and the preheated cold products are then transported in front of the heating chamber and are then seized by through another charging device to the enclosure reheating, in which they are brought to the rolling temperature at hot.
  • preheating installation necessarily requires the use of a number of charging devices and racking, transfer devices (roller tables), which generate a staggered layout of the two preheating and reheating, hence an important occupation on the ground, but also a greater cooling of the products between the two enclosures, phenomenon which is detrimental to lower energy consumption.
  • JP-A-61-279 615 describes a command and control system for the transport of the billets in a heating oven according to which one controls the transport speed of the billets, moving on side members mobile, by varying the intervals between billets, according to their temperature.
  • This system implements a computer as well as means of transfer.
  • EP-A-0 453 329 describes a device intended to ensure the unloading, the storage and transfer of steel products by implementing a system of mobile beams and fixed beams. Such a system is not not designed to perform loading or unloading functions between two heat treatment chambers, it is intended to supply or to discharge products into a processing enclosure. Otherwise, the problem, mentioned above, which the present invention seeks to solve is not discussed in this earlier publication.
  • the present invention therefore aims to overcome the drawbacks of the solutions known in the prior art who have never considered the problem intended solve this invention, the latter proposing a device which improves and simplifies transfers of metallurgical products between the enclosure of preheating and the reheating chamber which can therefore be switched on face to face (or aligned).
  • the invention relates to a transfer device between a first preheating chamber and a second heating chamber reheating, positioned between said enclosures, steel products to be transferred being initially arranged on fixed beams, characterized in that it comprises a chassis provided with an assembly constituted by the juxtaposition of a plurality of mobile beams and optionally a plurality of rollers, these being positioned between the first treatment enclosure and the second treatment enclosure, and at the end of a steel products transfer line, said mobile side members cooperating with both a lifting / depositing frame and with a front / rear translation chassis, said chassis making it possible to have the movable side members of the so as to ensure the transfer of steel products) between the first and second enclosure, or the transfer of products between the line the first enclosure or between the transfer line and the second enclosure.
  • an installation metallurgical product processing which is characterized in that it comprises a first enclosure, or preheating enclosure, one of which ends opens in front of a transfer device of the type specified above, which ensures continuity with a second enclosure, or reheating chamber, transfer of steel products taking place either from the preheating chamber to the reheating, either from a transfer line to the enclosure preheating or to the reheating enclosure, either from the enclosure preheating, or from the reheating chamber, to said line of transfer at the end of which is positioned said transfer device.
  • the cold products are designated by the reference 1, while that hot products are designated by reference 2.
  • the products are placed in the oven 4, while hot products are introduced via a lateral opening 3 made in the oven 4.
  • the cold products are represented by the reference 1, and by reference 2 hot products.
  • Cold products 1 after through a transfer device 7, are introduced into a preheating chamber 5 via a device in the oven 6. After passing through the preheating chamber 5, the cold products which have warmed up, are discharged via of a charging device 8 and are then positioned on another transfer line 9 which leads them, together with the products hot 2, to the heating chamber 10 which should bring the temperature of these products at the temperature of hot rolling.
  • Products hot 2 and cold products 1 are put in the oven, thanks to a device 11, into the enclosure 10 and are extracted therefrom via a device 12. This disposes the products which have reached the desired temperature of rolling, on a transfer line 13 which makes them travel towards the rolling mill 14.
  • Cold products 1 flow, via a transfer line 15 (produced here in the form of a roller table), towards a first enclosure or preheating enclosure 16. These products 1 are introduced, thanks to a charging device 17, in the enclosure 16. The products cold reach during their journey inside the enclosure 16, the temperature of the hot products 2.
  • the transfer device 18 comprises (see FIG. 4) a chassis disposed between the preheating chamber 16 and the reheating chamber 19.
  • This chassis is provided with an assembly consisting of a juxtaposition a plurality of movable side members 24 and a plurality of rollers 30, the latter being positioned in the same plane and in the continuity of the transfer line 20.
  • Fixed beams 23 are also located in the same plane as the floors of the preheating chambers 16 and of reheating 19, as well as in a plane parallel to the transfer line 20 (roller table) which conveys hot products 2.
  • the rollers 30 are not incorporated to the chassis of the transfer device 18, but reported substantially in the same plane as the fixed beams 23, from an annex chassis which cooperates for example at the level of the preheating chambers 16 and reheating 19.
  • the mobile longitudinal members 24 cooperate both with a lifting frame 25 and removal and to a front / rear translation frame 26. Movements chassis lifting / removal 25 and chassis front / rear translation 26 are provided respectively by lifting means 27 and by mechanical, hydraulic, or other translational means 28.
  • the lifting means 27 (thanks to the action combination of cylinders and inclined faces 29) ensure an elevation of the chassis 25 and therefore mobile spars 24, which raises the products 1.
  • the means 28 ensure a movement of front translation of the translation frame 26 in order to transfer the products 1 which are located on the mobile longitudinal members 24 inside the reheating chamber 19.
  • the lifting means 27 ensure the positioning of the movable beams 24 at the level of the fixed beams 23 located in the same plane as the bottom of the furnace 19, so as to deposit the products 1 in the reheating chamber 19.
  • the last operation consists in bringing the chassis 26 for translation and the mobile side members 24 which cooperate in the rear position, thanks to the translation means 28, which constitutes the starting position of the cycle.
  • the path of the mobile longitudinal members 24, by through frames 25 and 26, in relation to products 1, is identical to the operation of these same beams 24 for the transfer of products 2 coming from transfer line 20, towards the enclosure 19.
  • the fixed rollers 30 play the role of the fixed beams 23, the fixed rollers 30 being positioned at the end and substantially in the same plane as transfer line 20.
  • this invention relates to an installation of metallurgical treatment of steel products which includes the first preheating chamber 16, one end of which opens out opposite the transfer device 18, described above and which ensures the continuity with the second heating chamber 19, the transfer of steel products made either from the precincts of preheating 16 to the heating chamber 19, i.e. from the line transfer 20 to the preheating chamber 16 or to the preheating chamber reheating 19, either from the preheating chamber 16 or from the reheating chamber 19 towards the transfer line 20, at the end of which is positioned the transfer device 18.
  • the invention as described above offers multiple advantages. It allows the aligned arrangement of the preheating and reheating, which offers a considerable saving of floor space. She permits also to put hot products in the oven preheating to achieve temporary hot storage when the rolling mill is stopped and continuous casting is in operation.
