Definitions
- the present invention relates to continuous casting thin metal products, especially steel, according to the technique of continuous casting between two cylinders contra-rotating, and more particularly the management of contact and lubrication between the ends fronts of such cylinders and shutter walls lateral, applied against these frontal ends, to delimit the casting space defined between the cylinders.
- the molten metal is spilled in the casting space, defined between the cylinders, is solidifies on contact with them, and is extracted towards the bottom, when rotated, in the form of a thin strip.
- sealing walls side are pressed against the front ends cylinders.
- Such lateral closure walls are commonly made of refractory material, at less in their part brought into contact with the molten metal.
- a way known lubrication consists in depositing a material lubricant on the front surfaces of the cylinders. This deposit is for example (see document JP-A-63248547) produced by applying a solid bar to these surfaces a lubricant, for example comprising nitride of boron or graphite. Document JP-A-6015416 teaches achieve this deposition by spraying a material lubricant, the thickness of which is controlled by a adapted device.
- the regularity of contact can also be destroyed, during casting, by metal infiltration or tearing of the refractory material from the walls shutter, in the contact area.
- the object of the present invention is to resolve these problems, and is particularly aimed at ensuring perfect seal between cylinders and walls lateral shutters permanently during casting in managing the wear of said closure walls.
- the object of the invention is a process for the continuous casting of metals between cylinders, that molten metal is poured into a space of casting defined by the cylindrical walls of two cylinders with parallel axes, counter-rotating and cooled internally, and two fixed shutter walls side placed against the front surfaces end of the cylinders, and we deposit on these surfaces a lubricant to lubricate the interfaces cylinders-shutter walls, and we extract the product solidified in a direction of extraction substantially perpendicular to the plane containing the axes of the cylinders, characterized in that the quantity of lubricant is reduced brought into each of these interfaces be periodically, either in the event of deterioration in conditions friction or sealing at the cylinder-wall interface shutter.
- the amount of lubricant deposited depending on the effort exerted on the shutter wall in the direction extraction.
- variations in effort measured are representative of variations in conditions friction of the cylinders on the closing wall considered, these variations in friction being themselves indicators of a disturbance (infiltration, hooking or tearing) at the interface.
- moving the shutter wall is indicative of metal snagging infiltrated between said wall and the cylinder, this attachment having the effect of moving the wall away the front surface of the cylinder.
- the variation is varied. quantity of lubricant deposited according to parameters characteristics of the vibrations induced in the wall shutter during casting. As in the first variant above, variations in the vibration regime of the obturation wall are indicative of variations friction conditions, themselves indicative of interface disturbances.
- a preferential method one applies in permanently and with a substantially constant effort on each of the front faces of the cylinders, a stick of lubricant, and to reduce the amount of lubricant brought to the interface, we remove the lubricant deposited at the by means of a scraper or a brush.
- This method presents the advantage of obtaining a faster effect of the reduction or removing lubricant because it removes actually the lubricant on the surface front of the cylinder, as soon as the scraper and / or the brush are put into service, whereas the first method can let lubricant remain on the front surface of the cylinder for several turns of it before the consumption of lubricant, which occurs naturally in operation, does not lead to its reduction or effective deletion.
- the invention also relates to a device for continuous casting between cylinders, comprising two cylinders contra-rotating parallel axes, defining between them a pouring space, delimited by two sealing walls lateral, fixed and placed against the front surfaces end of the cylinders, means for depositing a lubricant on said front surfaces, means of measurement of one or more parameters representative of friction or sealing conditions at the interface cylinder-shutter wall, characterized in that it includes means for removing the lubricant present on said front surfaces when the value (s) of this or these parameters indicate a degradation of the said friction or sealing conditions, said means including a scraper or a brush associated with each front surfaces, and means of commissioning or out of service of the scraper or brush.
- Installation of continuous casting of thin strips steel shown schematically in the drawing of the Figure 1, includes two casting rolls 1, 2, of axes horizontal and parallel, spaced apart by a distance corresponding to the thickness of the strip.
- the metal in fusion is poured into the casting space 3 defined between the cylinders 1,2. These are internally cooled and rotated in opposite directions, so that during casting the steel strip is extracted down, in the direction indicated by the arrow F.
- the pouring space is delimited by fixed walls 4 lateral shutters, applied against surfaces front 5 of the cylinders by pressure means 20, such as springs or jacks, in a manner known per se.
- the walls 4 have, on the side of the casting space, a central part 6 of refractory material, preferably thermally insulating, bordered by two strips 7 which extend, according to a curvature corresponding to that cylinders, over the entire height of the wall 4.
- These bands 7, also called inserts, are made of a refractory material having good qualities of resistance to abrasion wear.
- the Ray of outer curvature of these bands 7 is slightly greater than the outer radius of the cylinders, so that a part 7 ′ of the strips 7 projects beyond the periphery cylinders and either, during casting, in contact with the cast metal. Therefore, it is therefore the remaining part 7 '' of each strip 7 which is in rubbing contact with the corresponding front face of each cylinder, for sealing the pouring space.
- the installation comprises means 8 for depositing a lubricant on the surfaces front 5, shown diagrammatically in FIG. 1, and shown in more detail in Figure 7, in a preferred embodiment.
- These means include, for each front face of the cylinders, a stick solid of lubricant 9, such as for example nitride of boron or graphite, guided in a tubular support 10 fixed to the structure 11 of the installation.
- the stick 9 is pushed against the front surface 5 of the cylinder 1 by a pressure means such as a spring 12, or a jack.
- the spring 12 supports the lubricant stick 9 on the front surface 5, in permanently and with a substantially constant effort throughout the casting.
- lubricant is therefore deposited and distributed over the entire circumferential part of the front surface 5 of the cylinder 1, and can be brought by this rotation, to the contact interface between this surface and the part 7 '' from the insert 7 of the closure wall 4, to provide lubrication.
- the installation also includes adjustment means the quantity of lubricant supplied to the interface, comprising, associated with each front surface 5 of the cylinders, a scraping system 13 and a brush rotary 14, driven in rotation by a motor 15.
- the scraping system shown more detailed in FIG. 8, includes a scraper 16 in blade shape that can be applied in contact with the frontal surface 5, or distant from it, by a jack 17, or an equivalent displacement control means.
- Brush 14 can similarly be applied with controlled force against the surface frontal 5, or be distant from it, by means of equivalent displacement, not shown.
- the installation also includes measuring means 18 of the position in the axial direction of the cylinders, of the closure wall 4, with respect to the front surface 5.
- These measuring means make it possible to determine variations in wall position shutter, and therefore give indications on the operating conditions of the installation at the level the cylinder - end wall interface, in particular on the tightness of the casting space at this level interface. For example, when cast metal seeps between the cylinder and the closing wall and forms in se solidifying a hook 21 adhering to the wall shutter 4, the presence of this attachment repels the wall against the effort exerted by the means of pressure 20, creating a game at the interface, harmful to sealing, and detectable by the measuring means of displacement 18.
- Line 30 in Figure 6 shows the position of the closure wall 4, with respect to the general structure of the installation, depending on the time.
- Part 31 of route 30 corresponds to the start of casting, during which we observe a displacement progressive closure wall 4, result of a relatively rapid wear of refractory material constituting the insert 7. This period corresponds to a running-in of the insert by friction of the cylinder during its rotation, until the two surfaces are in intimate contact which ensures a good seal.
- the temporary reduction or removal of interface lubrication can also be performed by a removal of the application of the stick 9 on the front surface of the cylinder.
- the invention makes it possible in particular to avoid using for the inserts a self-lubricating material, for example example with high boron nitride content, less material resistant and more expensive, ensuring the lubrication of the cylinder-shutter interface by through the front surfaces of the cylinders, at instead of ensuring this lubrication by the inserts themselves.
- a self-lubricating material for example example with high boron nitride content, less material resistant and more expensive
- the invention is not limited to the device method described above by way of example.
- the deposit of lubricant on the front surfaces of cylinders can also be achieved by other means as the sticks described above, for example by liquid lubricant application systems or pasty, projection of liquid or powdery lubricant, etc ...
- the relative provision of the means of lubrication 8, brush 14, closure wall 4 and scraper 13, shown in FIG. 1 in this order depending on the direction of rotation of the cylinders can be modified; the lubrication means 8 being able to particular be placed between the brush and the wall shutter, the effect of brushing then still being remarkable in that the lubricant deposited after brushing is found in reduced quantity compared to this which would happen without any brushing.
- scrapers which, being placed downstream of the closing wall in the direction of rotation, ensure also the elimination of possible metal snags on the edges of the cylinders, can be placed also upstream, but after the means to lubrication, and in addition to or in place of brushes.
- the load cell 19 is therefore used to measure the force exerted on the wall 4 resulting from the friction of the cylinders 1, 2 rotating on this wall, this effort depending on the friction conditions and therefore in particular of the application force of the wall 4 on the cylinders, in the direction of two axes, from the surface contact, and lubrication conditions.
- Variations in the measured effort are representative of changes in the conditions of friction at the interface, which can be caused either by abnormal localized wear of the wall obturation, or tearing of its material, or also seepage of cast metal and snagging of metal on said wall.
