Definitions

  • the present invention relates to an installation for cooling a moving metal product.
  • any metallic product in scrolling movement, having at least one flat surface.
  • rolled products such as sheets, in particular heavy and medium sheets, thin strips, profiles as well as continuous casting products, such as slabs and billets.
  • This known device however has certain drawbacks that are all the more marked the greater the width of the product to be cooled.
  • the present invention relates to an installation making it possible to eliminate these drawbacks.
  • a device for cooling, by means of an aqueous liquid, a metallic product having at least one flat surface, said metallic product moving along a predetermined trajectory comprises a wall disposed opposite said flat surface of the product to be cooled and in a substantially parallel to the latter, so as to form between said flat surface and said wall, a space of substantially constant thickness.
  • the wall is pierced with at least one orifice which on the one hand opens into said space while ensuring the passage of the aforementioned aqueous liquid through said wall, and which on the other hand is connected to a source of said aqueous liquid.
  • This device comprises means for adjusting the flow rate of the aqueous liquid and the distance between said wall and the flat surface of the product to be cooled.
  • a device of this type is known from patent FR-A-2 223 096.
  • the orifices can in particular be staggered, at least in the part of the wall which faces the flat surface of the product to be cooled.
  • the orifices are advantageously lined with rings, for example brass or stainless steel, the internal diameter of which has the desired value.
  • the wall pierced with orifices preferably constitutes one face, called the front face, of a distribution box for the aqueous liquid on the flat surface of the product to be cooled.
  • the holes drilled in the front face of said box are then advantageously provided with tubular end pieces extending inside the box. It is preferable that the length of these tubular end pieces is preferably not less than five times their internal diameter.
  • tubular tips are preferably made of a material resistant to corrosion by the aqueous liquid, preferably brass or stainless steel.
  • tubular end pieces makes it possible to prevent the orifices from being blocked by materials possibly depositing at the bottom of the box when it is a box whose water escapes through the bottom wall, and to improve the homogeneity of the distribution of the aqueous liquid to the said orifices.
  • the present invention relates to an installation for cooling a metallic product, applying the device which has just been described.
  • the cooling installation which is the subject of the present invention comprises several devices conforming to those which have been described above, arranged opposite at least one surface, but preferably opposite all the flat surfaces of the says product.
  • this installation it is advantageous for the walls pierced with orifices belonging to the said devices located opposite the same flat surface of the said product to be arranged in the same plane and for the said walls to follow one another in the direction of travel of the product.
  • Figure 1 shows a sheet 1 which, at its exit from the rolling mill 2, moves on a roller conveyor 3 in the direction of arrow 4.
  • This sheet passes through a cooling installation according to the invention, comprising on the one hand lower boxes 5 arranged between the rollers 3 of the conveyor, and on the other hand upper boxes 6 arranged substantially above the lower boxes 5.
  • These lower and upper boxes are supplied with aqueous liquid respectively by the inlet pipes 7 and 8.
  • Between the upper boxes 6 are placed spacers 9 whose lower face is located in the plane containing the walls pierced with orifices of said upper boxes.
  • spacers ensure on the one hand, the continuity of the surface facing the product and therefore the consistency of the thickness of the space 10 supplied with aqueous liquid and on the other hand, the maintenance of the spacing chosen between neighboring caissons. They also make it possible to eliminate any risk of catching of the sheet by the upper boxes.
  • the aqueous liquid delivered by lines 7 and 8 is discharged to a collector (not shown), after having cooled the sheet 1 in space 10.
  • FIG. 2 shows in particular a sheet 1 entering the cooling installation.
  • the sheet 1 moves on the rollers 3, between which the lower boxes are disposed 5. These are positioned so that their front face is located at a distance between 10 mm and 100 mm below the contact plane between sheet metal and rollers. These distances make it possible to avoid any risk of catching of the sheet by the lower boxes, while ensuring satisfactory cooling efficiency.
  • the boxes 5 are individually supplied with aqueous liquid from the pipe 7; each individual connection 11 is provided with a valve 12 making it possible to isolate the corresponding lower box.
  • the upper face of the boxes 5 is pierced with orifices 13, the diameter of which is between 0.5 mm and 10 mm, and preferably between 1 and 5 mm.
  • the number of these orifices is at least 100 per square meter, for the orifices with the largest diameter; it increases when the diameter decreases, so as to maintain the passage section, and consequently the desired flow rate of aqueous liquid.
  • the front face of the lower boxes is, again according to the invention, provided with teeth 23 projecting substantially horizontal, preferably upstream, to guide the sheet while allowing the flow of part of the aqueous liquid. .
  • each upper box 6 Opposite the lower boxes 5 are upper boxes 6 whose front face, that is to say the face facing the sheet 1, is also pierced with orifices similar to the orifices 13. It is not imperative, for the present invention, that each upper box 6 is located strictly opposite a lower box 5; the spacing between the upper boxes can be different from the spacing between the lower boxes, without departing from the scope of the present invention.
  • the upper boxes 6 are supplied with aqueous liquid from a pipe 8; each connection 14 is subdivided into two individual conduits 15 and 16, each supplying a box and provided with valves 17 making it possible to isolate the corresponding upper box.
  • the intervals between the upper boxes 6 are occupied by spacers 9.
  • spacers 9 are appropriately secured to the boxes 6, and their height is greater than that of these boxes 6
  • the rear face of the spacers 9 is projecting from the boxes 6.
  • the spacers 9 are rigidly fixed, preferably by welding, to beams 18 which are in turn supported by transverse gussets 19.
  • the ends of these gussets 19 are supported by jacks 20 on bases 21 integral with the foundation of the 'installation.
  • jacks 20 make it possible to vertically move the rigid assembly formed by the gussets 19, the side members 18, the spacers 9 and the upper boxes 6, so as to vary, as necessary, the distance between the front face of the boxes 6 and the upper surface of the sheet 1.
  • the jacks 20 are driven, by means of a distribution known per se, by means of a motor 22 mounted, according to the invention, behind the spacers 9 and preferably in the longitudinal median plane of the set of spacers - upper boxes. The motor 22 is thus protected against the vapors which inevitably emerge from the cooling space.
  • the spacers 9 and the side members 18 are hollow and closed at their ends, and they communicate with each other at their crossing points; they thus form a circuit, traversed by a cooling liquid, preferably water, so as to avoid any deformation by heating in the event of blockage of a hot product inside the installation.
  • a cooling liquid preferably water
  • This coolant advantageously comes from the cooling circuit of the rolls of the rolling mill located upstream, so that its supply is independent of the supply circuit of the boxes and is therefore not disturbed in the event of reduction or interruption - voluntary or accidental-of the supply of the boxes 5, 6.
  • a partition 24 preferably vertical, which prevents any untimely lateral flow of the aqueous coolant.
  • This partition obviously has inlet and outlet openings for the sheet in the installation. Still according to the invention, these openings are capable of means to prevent the aqueous liquid from flowing through these openings.
  • These means are advantageously constituted by devices for spraying aqueous liquid in the transverse direction which discharge the aqueous liquid into the space between the partitions and, from there, towards the collector.
  • the entry opening formed in said vertical partition is equipped, according to the invention, with means for guiding the sheet coming from the rolling mill and having to enter the installation.
  • These means are advantageously constituted by a guide or deflector, which can itself be made of sheet metal, forming a funnel in front of said inlet opening.
  • FIG. 3 illustrates the circuits for supplying aqueous liquid to the lower and upper boxes, as well as the device with jacks ensuring the height positioning of the upper boxes.
  • connection 11 connected to one end of the box is, according to the invention, equipped with a bypass 25 which transfers half of the flow of aqueous liquid to the other end of the said box.
  • Each conduit 15 is connected to one end of a box 6 and it is equipped with a bypass 26 which transfers half of the flow of aqueous liquid to the other end of said box.
  • connection 14 comprises, in accordance with the invention, means making it possible to ensure, without loss of tightness, the mobility of the assembly comprising the upper boxes relative to the supply line 8.
  • connection consists in fact of a first part 14 and a second part 14 'whose diameter is slightly less than that of the first part 14.
  • the end of the part 14 ′ is engaged and can slide in the part 14, in response to variations in the height position of the upper boxes 6, and the seal between the two parts is ensured by an elastic membrane controlled by pressure of a gas.
  • the orifices 13 of the upper boxes 6 are advantageously provided with tubular end pieces 28 extending inside the boxes.
  • tubular tips facilitate the protection of the boxes 6 against deformation by heating in the relatively frequent case where the installation is crossed by a sheet which must not be cooled by this means.
  • the upper boxes 6 are in fact power of an evacuation orifice 29 situated at a level lower than that of the head of the tulip tips 28. If necessary, it is thus possible to establish and maintain a slight flow of aqueous liquid ensuring the cooling of the boxes 6 without this liquid flows undesirably onto the sheet.
  • the protection of the lower boxes 5 is ensured by maintaining a flow rate of aqueous liquid sufficient for it to flow through the orifices 13, but insufficient for it to reach the underside of the sheet not to be cooled. .
  • aqueous liquid delivered by the orifices 13 of the upper and lower boxes is collected by the collector 30 then, after filtering and cooling by devices not shown, it is returned to the pipes 7 and 8.
  • a make-up of aqueous liquid can, on this occasion, be added to compensate for losses, in particular by spraying.
  • FIG. 3 also shows the mechanization system of the mobile upper assembly, consisting of the motor 22 and the jacks 20 to which the movement is transmitted by a distribution of known type.
  • the stroke of these cylinders is such that the thickness of the space 10 can vary from 5 mm to 300 mm, and preferably between 30 mm and 300 mm in the case of sheets, in order to avoid any risk. attachment while maintaining a satisfactory cooling efficiency.
