Definitions

  • the present invention relates to the casting of metals and in particular to the continuous casting of metals.
  • a further object of the present invention is to provide a horizontal continuous cast-ing process and apparatus which will guarantee that the molten metal in the mold is at such a pressure that cavities or the like cannot form in the molten metal, while -at the same time the use of structure providing a great head of metal is avoided.
  • the invention includes, in a process for continuously casting metal, the steps of continuously directing metal from a suitable source thereof in molten condition into the inlet end of an elongated horizontal mold the discharge end of which remains open so that the metal continuously discharges ⁇ from the mold with at least the exterior surface of the metal solidified; and magnetically pumping the molten metal from the source thereof into the mold to maintain in the molten metal in the mold a pressure in excess of that which -it would have without the pumping so that in this way it becomes possible to provide within the lhorizontal mold a pressure great enough to avoid the formation of cavities, as discussed above.
  • an apparatus which includes a tundish formed at a substantial distance below its top end with a discharge opening through which molten metal in the tundish can discharge therefrom.
  • a magnetic pumping apparatus communicates with the opening of the tundish to receive molten metal thercform and to pump the metal from the tundish so as to provide in the molten metal a pressure greater than that which it derives from the head of metal in the tundish, and the thus-pumped metal is delivered lto the inlet end of an elongated horizontal mold through which the metal continuously moves to discharge therefrom continuously with at least the exterior surface of the metal solidified, and a means cooperates with the metal as it issues from the mold to guide the metal as well as to control the rate with which the metal issues from the mold so that this latter means can even retard the pushing of the metal from the mold Iby the pressure derived from the pump so as to provide the. best possible treatment of the metal.
  • FIG. l is a partly diagrammatic longitudinal sectional elevation of yan apparatus according to the present invention.
  • FIG. 2 is a wiring diagram illustrating the manner in which the coils of ⁇ the magnetic pump are electrically Wound.
  • FIG. 3 is a transverse sectional view of the structure of FIG. l as seen from the right end thereof, FIG. 3 showing the manner in which the solidified metal is treated upon issuing from the mold.
  • a tundish 1 containing molten metal 2 in a conventional manner, the tundish 1 including an outer steel casing 3 lined with a refractory lining material 4.
  • the tundish receives the molten metal from one or more ladles which are emptied into the tundish, in a manner well known in the -art and not illustrated.
  • the slag which forms on the upper part of the molten metal can be removed over the portion 5 which takes the form of a lip or spout permitting the slag to discharge from Van upper portion of the tundish 1.
  • the exterior surface of the nozzle '7 mates with the surface of the opening formed in the wall 6 so that the nozzle 7, which has an exterior ltapering surface is in this way fixed with the tundish 1 in the frustoconical opening thereof, and thus the molten metal will ow out of the tundish 1 through the nozzle 7 thereof.
  • the metal which discharges from the -tundish 1 through the opening or nozzle 7 has the pressure, which is already present due to the head of metal in the tundish 1, augmented by a magnetic pumping action provided with a magnetic pump assembly 8 which is further described below.
  • the metal flows through the magnetic pumping means 8 in yan elongated conduit 9 which is made of a refractory material of high electrical resistance, and the cross section of the conduit, particularly at its interior through which the metal flows, is substantially rectangular and very fiat, which is to say the height or depth of the channel in the interior of the conduit 9 is extremely small with respect to the width thereof so that a Wide film or ribbon of molten metal of small thickness flows continuously through the magnetic pumping means 8.
  • the refractory conduit 9 may be made, for example, of fritted or chamotted alumina, or it may be made of zirconia, or from a mixture of these two refractory mate-
  • the tundish 1 and the pumping device 8 are connected to each other in a fluid-tight manner by a refractory conduit 10 of circular cross section, and the conduit 10 is surrounded by a cylindrical casing 11 made of steel and fixed by flanges 12 to the other elements, the bolts which pass through the flanges 12 'being omitted for the sake of clarity.
  • the electromagnetic pumping means 8 is designed so as to be capable of providing a flow of molten steel at the rate of 50 tons per hour under a pressure which at a maximum is ten atmospheres.
  • the metal which is under pressure will be delivered to the elongated horizontal mold 13 which is cooled by circulating cooling water and to which the pump is connected by way of a refractory cylindrical conduit 14 housed within a metallic also cylindrical casing 15.
  • the casing 15 has a double wall so that it is provided in its interior with an annular passage surrounding the conduit 14, and a pair of tubes 16a and 16b communicate with the inner annular space of the doublewalled conduit 15, so that through these tubes it is possible to circulate cooling liquid which thus surrounds the conduit 14.
  • conduit 14 together with the casing 15 are fixed to the remainder of the assembly in the position shown in FIG. l by Way of flanges 17 and unillustrated bolts passing therethroughu
  • a ring 18 formed with an annular passage 19 which communicates through a circular row of small openings 20 with the interior of the mold 13 at the inlet end thereof, and a suitable lubricant is supplied through the pipe 21 to the space 19 to flow from the latter through the small openings 20 into the mold 13 together with the molten metal which penetrates into the mold from the pump 8.
  • a lubricant is provided to move along the inner surface of the mold 13, and this lubricant is supplied under pressure through the pipe 21 and can be a well known lubricant such ⁇ as oil of colza in which pulverulent graphite is suspended.
  • the elongated mold 13 is circular in cross section and can be made of copper, and is cooled by a cooling liquid such as water circulating around the exterior of the mold.
  • an elongated envelope 22 in the form of an elongated pipe having intermediate its ends a fexible portion 23 which has the construction of a bellows or the like and which is capable of expanding and con-tracting in a manner well known in the art so that in this way it is possible to compensate for the different rates of thermal expansion of the envelope 22 and the mold 13.
  • the elongated metallic tubular envelope 22 carries at its ends flanges 24a and 2412 which by way of suitable bolts are xed to anges at the end of the mold 13 so that in this way it is possible to fix the ends of the envelope 22 to the end walls of the mold 13 in a fluid-tight manner enabling the envelope to define with the exterior surface of the mold an elongated hollow chamber through which a cooling liquid may be circulated in the manner indicated in FIG. 1. With this construction it is a simple matter to disconnect the envelope from the mold so as to enable the latter to be exchanged for another mold after the mold 13 becomes worn.
  • a porous element through which the gas can escape.
  • a porous element through which the gas can escape.
  • a porous member of this type should have ⁇ a relatively small thickness because the thermal ⁇ conductivity thereof is not as favorable as that of the copper of the mold itself, and the cooling of the material will be undesirably effected by too great of a thickness of such a porous member.
  • FIG. 3 shows the section of the bar 25 which is continuously molded, and it will be seen that this bar is of circular cross section, and in laddition FIG. 3 shows the curvature of the perip-heral grooves of the rolls 26a and 26b. Also there is seen in FIG. 3 the flange 24h at the end of the cooling envelope 22 and connected to the end of It will be seen that the rolls 26a and 26b have a structure similar to pulleys.
  • rollers 28a and 28b The entire assembly is carried by suitable framework 27 on which rollers 28a and 28b rest, and these rollers permit the envelope to move freely with respect to the receptacle 1 so Ias to automatically compensate for eX- pansion and contraction of the elements during heating and cooling thereof and this compensation takes place through the free rolling contact of the rollers 28a and 28b on the frame 27 without any undesirable restraint on the parts.
  • the extent of elongation of the parts during operation can be on the order of a few tens of millimeters, and this elongation is easily taken care' of by the 4rolling of the rollers 28a and 28b on the frame 27.
  • FIG. 1 With respect to the electromagnetic pump means 8, it will be seen from FIG. 1 that it is traversed by the refractory conduit 9 which passes, therethrough, as described above.
  • a plurality of electrically conductive bars 29 which extend horizontally, perpendicular-ly to the conduit 9 and to the plane of FIG. 1, so that these bars 29 . also extend perpendicularly with respect to the direction of flow of the molten met-al.
  • These electrically conductive, transversely extending bars 29 ⁇ are situated in slots which are formed in the magnetic, laminated masses which are not shown in FIG. l and which are situated above and below the conduit 9, ⁇ and the active surfaces of these magnetic masses are illustrated diagrammatically at 30a and 30h in FIG. 2.
  • FIG. 2 FIG.
  • FIG. 2 also clearly illustrates how the several electrically conductive bars 29 extend across the magnetic laminated masses.
  • the structure situated above the conduit 9 and the structure situated -below the conduit 9 are shown separately in FIG. 2 displaced from each other so as to clearly illustrate the manner in which the parts are electrically connected to each other, but it is to be understood that in the lactual construction the two sections shown in FIG. 2 are placed one above the other.
  • the several bars 29 are electrically connected so as to form the series-connected imbricated, three-phase windings similar to the windings of the field of an induction motor and supplied with current from a three-phase source of electricity A., B, C.
  • the entire construction is the same as that of the stator of an asynchronous three-phase motor which has been unrolled from its cylindrical conguration into a at conguration.
  • the rotating field of such an asynchronous motor is thus replaced in the magnetic pump by a longitudinally shifting field whose lines of force extend perpendicular-ly to the plane of FIG.
  • the vertical thickness of the refractory conduit is made as small as possible, and in an actual construction the molten metal flowing through the conduit 9 has the form of a ribbon or sheet of metal having a thickness of approximately l cm. and a width of ⁇ approximately cm.
  • the pump 8 is designed to provide a maximum flow of molten steel at the rate of 50 tons per -hour under a pressure in the neighbourhood of l0 bars.
  • the structure includes sixty electrically conductive bars 29 above the conduit 9 vand also sixty bars 29 below the conduit 9, and the current which flows through these bars is on the order of 3,00() amperes, and the power required for the pump is on the order of 150-200 kw.
  • the electrical windings are clearly shown in FIG. 2.
  • phase A windings which cooperate with phase A are all shown in solid lines, while the phase B windings are shown in dotted lines, and the phase C windings are shown in dot-dash lines, so that the manner in which the bars 29 are interconnected is clearly apparent from FIG. 2.
  • the molten metal issues from the outlet 31 of the pump 3, and thus it is introduced under pressure into the mold 13 where it starts to solidify at the inner ⁇ surface of the mold 13.
  • the pressure of the molten metal acts on the skin of solidied metal which forms at the inner surface of the mold and this pressure of the molten metal tends to keep the solidifying exterior skin of metal in contact with the mold wall so that in this Way the tendency of the solidifying metal to contract away from and fail to engage the inner surface of the mold is negated and also in this way the poor heat exchange which would result from separation of the exterior surface of the molten metal from the inner surface of the mold is also eliminated.
  • any cavities which always tend to form during the cooling of an ingot or a bar or the like because of contraction of the meta-l after the exterior skin of the metal has already solidified is prevented from forming with the Iprocess and apparatus of the invention by the continuous permanent supply of metal under pressure which acts in the interior of the mold 13 so as to prevent the formation of cavities, piping, or the like.
  • an additional intense cooling can be provided on the bar 25 issuing from the mo-ld by spraying or sprinkling the bar with water in a manner well known and not shown, and if desired the bar can even be passed through a suitable bath of cooling liquid so that it is immersed in the liquid.
  • the rollers 26 situated at the discharge of the mold 13 guarantee proper guiding of the mold material and extraction of the bar 25 from the mold in a uniform manner.
  • the rolls 26a Iand 2611 are driven at a constant speed which can be adjusted, by way of an electric motor, in a manner well known.
  • the speed with which the bar issues from the mold is controlled by controlling the speed of rotation of the .rollers 25a and 26h as well as by controlling the electrical current in the windings of the magnetic pump, and of course this adjustment or of the current in the windings of the magnetic pump 8 is also controlled so as to automatically compensate for variations in the head of molten metal in the tundish il, so that in this way metal at a substantially constant pressure will be supplied to the mold 13.
  • the turning rollers 26a and 2611 guarantee a uniform advance of the bar 25 and they may apply a very slight tension tending to pull the bar 25 from the mold.
  • rollers 26a and Zeb at such ⁇ a slow rate that they resist the speed of issue of the bar 25 from the mold and retard the issue of the bar so as to guarantee that the bar remains in the mold for a predetermined length of time which greatly improves the structure of the molded bar issuing from the mold.
  • the circular cross section of the bar 2S is not essential and it is possible to produce with the process and apparatus of the invention bars of square or rectangular cross section or of any other desired prole.
  • the process and apparatus of the invention are of particular advantage for the casting of products of relatively small cross section, because the process ⁇ and apparatus of the invention enable the speed of casting to be increased considerably, as compared to known casting processes.
  • the pressure of ten bars referred to above is not essential and the advantages of the invention can of course be obtained with other pressures, in particular lower pressures which might be used under other conditions.
  • the molten metal will at all times be introduced into the mold 13 at a pressure which is sufficiently high to guarantee that the mold f3 is at all times completely filled and to avoid or .at least reduce to a very great ⁇ extent the possibility of the formation of cavities or piping in the body of the molten material.
  • the fact that the pressure of the molten metal entering into the mold 13 guarantees the complete filling thereof at all times serves to maintain the exterior surface of the material entering the mold in engagement with the interior surface of the mold so .as to very greatly improve the heat exchange between the material which is being molded and the mold itself, so that in this way also the solidication of the metal is greatly facilitated.
