Definitions

  • the invention relates to a method and a device for correcting thermal ovality (or runout) appearing on rolls of continuous metal strip casting.
  • a continuous metal strip casting machine generally contains two identical cylinders located face to face, separated by a space of the thickness of the metal strip to be produced and rotating in opposite directions from one another.
  • the liquid metal is fed on one side of the space while the strip leaves the other side at its nominal thickness.
  • Bands ranging from a few centimeters in thickness to a few millimeters or less can be produced with such a device.
  • Figures 1 (longitudinal section) and 2 (cross section) give the general structure of a cylinder.
  • the cooling is usually carried out using a cooling fluid (generally water) circulating in at least one cooling circuit located inside the cylinder body (1).
  • a cooling fluid generally water
  • This circuit comprises at least one cold water supply hole (3), in the form of a tube drilled in the cylinder body (1), parallel to its axis, opening to the outside by one of its ends, the other being closed, and extending to the right of the hoop (2) over its entire width.
  • a plurality of smaller diameter tubes (4) connect each supply hole (3) to a distribution manifold (5) a sort of groove located under the hoop (2) and substantially parallel to the supply tube (3); each collector supplies water to a cooling device proper comprising a network of small channels (5) machined on the peripheral surface of the cylinder body (1) and located under the hoop in a transverse plane; the water circulates there and comes into thermal contact with the hoop and ensures its cooling.
  • a device identical to that of the supply includes (see lower part of fig. 1 and fig. 2) an evacuation manifold (7) of hot water, a plurality of small diameter tubes (8) connecting it to the evacuation tube (9).
  • a cylinder body has two or three or four water supply circuits and as many discharge circuits interconnected by the channels (6) of the cooling device.
  • the reciprocal arrangement of the cold water and hot water circuits is clearly visible, in particular in FIG. 2 which represents the case of 2 circuits. We see their interconnection and their alternate arrangement and offset from each other by 90 °. The arrows illustrate the direction of water circulation. In the case of three or four circuits, the offset is 60 ° or 45 °
  • the cold water arriving in one of the distribution collectors (5) is then distributed in the cooling channels (6) located on either side of the collector (5), heats up and is evacuated by the collectors (7 ) which thus recover the water coming from two distribution collectors (5) located on either side.
  • the Applicant has sought a method and a device aimed at reducing the temperature differences in the cylinder which is effective and easy to carry out or to implement and inexpensive.
  • the invention is a method of cooling cylinders for continuous casting of metal strip using a fluid
  • said metal cylinders comprising a cylinder body and a metal hoop consisting essentially of a tube or a metal casing, the inner face of which surrounds said body, the other face serving to receive liquid metal and to produce the strip by the cooperation of two cylinders
  • said cylinder body comprising at least one cooling circuit opening out from the body cylinder by two inlet / outlet ends and comprising at least one device for supplying cold fluid (generally water), a cooling device proper where the fluid is in thermal contact with the underside of the hoop and a device for discharging the heated fluid in contact with the hoop, characterized in that the direction of circulation of the fluid is periodically reversed e in the cylinder body, the cold fluid supply device becoming the hot fluid evacuation device and vice versa.
  • the invention is particularly suitable for cylinders having the configuration described above using FIGS. 1 and 2, their cylinder body comprising two or three or four cold water supply devices alternated with as many hot water discharge devices, these devices being offset by 90 ° (two devices), 60 ° (three devices) or 45 ° (four devices) and connected by a cooling device proper.
  • Continuous strip casting generally takes place between two identical cylinders, the reversal of direction of the cooling fluid according to the invention is advantageously carried out on the two cylinders.
  • Such a process is also applicable to casting on a single cylinder, for example film casting.
  • the process according to the invention is particularly advantageous when thin strips are poured, for example from 1 to 12 mm thick, or even thinner, specifically in the usual range of thickness from 5 to 12 mm where the process is very effective, or also in the area of small thicknesses, for example from 1 to 5 mm, for which a cylinder runout is all the more detrimental the smaller the thickness. It is particularly suitable for casting strip of aluminum or its alloys.
  • the frequency of reversing the direction of water circulation must be adjusted according to the characteristics of the installation, for example cylinder diameter, coolant flow rate, etc.
  • the method according to the invention has been applied to an installation for continuous casting of 8 mm thick strip of aluminum, on cylinders with an outside diameter of 96 cm, the hoop of which was 8 cm thick, and having an internal cooling circuit identical to that given in FIGS. 1 and 2.
  • the buffer tank can receive the hot fluid if it is large enough to cool it or if it has an autonomous cooling device.
  • valve V is assigned to supply the cylinder with cold fluid, while the valve W is assigned to the evacuation of the heated fluid.
  • maneuvers can advantageously be automated or managed by microprocessor, computer ... etc ...
  • the second cylinder a circuit identical to that supplying the first cylinder, these two circuits being able to be mounted in bypass on the discharge of the pump.
  • FIG. 3 illustrates a device according to the invention for a casting machine comprising two cylinders: C (upper cylinder), D (lower cylinder).
  • C1, C2 and D1, D2 represent the input / output ends, interchangeable during the reversal of direction of the fluid, of the fluid cooling circuit located inside each of the cylinders C and D respectively.
