  • the metal end plates 44 limit upward movement of the entire nozzle assembly and thus prevent crushing of the blocks, particularly the nozzle tips. Also they serve to limit lateral bodily move ment of the rollers toward each other.

  • the nozzle blocks 36 are preferably arranged in complementary pairs divided along a plane perpendicular to the plane defined by the axes of the rollers 10.
  • the nozzle blocks may extend the length of the rollers. However, it is preferred to divide the nozzle blocks into relatively short sections, as indicated best in Fig. 3, to facilitate manufacture and replacement of the nozzle blocks.
  • Each complementary pair of nozzle blocks forms a trough having a horizontal passageway 37, the side walls of which converge upwardly to form a relatively narrow nozzle slit 38, as shown best in Figs. 5, 6, and 8.
  • Bosses 39 project laterally from opposite sides of the nozzle slit 38 to form lateral supports for the upper portions of the nozzle blocks so as to maintain a nozzle slit of constant width.

  • the rollers 10 are adjusted to provide a predetermined spacing therebetween and the support bar 30 is raised so as to bring the nozzle blocks 36 into running engagement with the rollers 10.
  • the rollers are rotated and coolant is circulated through the coolant passages.
  • Molten metal is poured into the box 50 and caused to flow through the conduit blocks 47 and passageway 37,
  • the rollers grip and carry away the solid metal. If the rollers are turning too slowly, the metal solidifies faster than it is carried away. Under this condition, the entire mass of metal above the nozzle tip becomes solidified, and in addition progressively solidifies downward into the nozzle tip with the result that the entire mass of metal, including the nozzle tip, is drawn between'the rollers and crushed.
  • the proper speed is relatively easy to determine. If the speed is too slow, cold laps may be apparent in the surface of the material and the power required to drive the machine will sharply increase. This condition can be readily detected by an ammeter connected to the driving motor and the roller speed changed accordingly, before damage occurs.
  • voids or hot-spots will appear in the strip, that is, areas. where the metal is not picked up by the rollers. This may occur at either or both edges or any spot across the width of the strip. The metal below these void areas continues to remain molten and is not elevated in the hotshort stage such as occurs during the starting period.
  • This phenomenon is due to two conditions: first, the fact that heat transfer is much more rapid where the rollers are in contact with the metal which has solidified, and, second, that the molten metal below the void tends to well up and flow laterally toward that area where solidification is still taking place. If the machine is slowed down slightly, the void areas will gradually close until uniform solidification prevails across the entire width of the rolls.
  • the solid metal, designated C, after passing upwardly between the rollers, may be coiled or fed into other rollers or otherwise subjected to further treatment.
  • the diameter of the rollers is quite large as compared to the distance between the nozzle tip and the plane A common to the roller axes.
  • the angle defined between the plane A and the nozzle tip represents only a few degrees of the roller circumference. In the construction illustrated, this angle, designated D, is approximately 9". The angle may vary between 5 and depending upon the size of the rollers and the metal being cast.
  • complete solidification of the metal occur at a level designated E in Fig. 6, which is slightly below the plane A.
  • the optimum level of complete solidification is such that the difference in distance between the rollers at the level E and at the level A is approximately equal to the shrinkage of the metal as it decreases in temperature between these two levels.
  • the nozzle blocks 36 should conform to the rollers 10 close enough to prevent back flow of metal between the nozzle tips and the rollers, particularly during the starting period. This does not mean that a forced bearing contact is required. A clearance of from .005 to .015 and more, depending upon the metal being cast, may be tolerated between the nozzle tips and the rollers. Progressively greater clearance may be permitted below the nozzle tips.
  • the slight clearance thus afforded reduces materially heat transfer from the nozzle blocks to the rollers.
  • Such heat transfer is, of course, also minimized by the use of ceramic or ceramic-like material having good heat-insulating properties.
  • the use of an insulating material for the nozzle blocks is desirable so that the temperature of the metal will not be appreciably reduced in its travel from the supply box to the casting region between the rollers.
  • a ceramic is selected which is inert relative to the metal being cast and which is not wetted by the molten metal.
  • the nozzle blocks may be peheated. In practice, this is done before insertion of the nozzle blocks into the machine by causing the molten metal to flow through the nozzle blocks until bubbling, caused by vaporizing of absorbed moisture, ceases. After this, the nozzle blocks are cleaned of solidified metal and inserted in the machine.
  • rollers It is essential that the rollers be completely free of foreign matter which would cause unequal heat transfer from the rollers to the metal. For example, a mere thumb print on the surface of. the roller will change the rate of heat transfer in the area of the thumb print sufficient to cause a hot spot in the product. That is, in this region a hole or depression will occur in the cast product. After several revolutions, however, the effect of the thumb print is completely dissipated.
  • the provision of a slight head of molten metal to produce metal flow ensures the presence at all times of a continuous column of molten metal behind the solidifying zone so that sound metal is formed and withdrawn continuously. At the same time, if the rate of solidification is decreased for some reason, there is no force present to cause the escape of molten metal from the apparatus.
  • the heat-absorbing capacity of the metal comprising the roller shell 13 can be relied upon to extract the required heat from the molten metal, without depending upon the liquid coolant immediately behind the portion of the shell 13 contacting the molten metal to absorb heat. That is, it may be considered that the metal shell itself absorbs the heat from molten metal being cast and then later transfers the heat to the coolant. As a result the shell 13 can be quite thick as it is fully supported by the core, so that the rollers can exert ample working pressure against the metal.
  • the metal or other material employed for the shell 13 depends on the metal being cast. It should not be wetted by the molten metal or react therewith, and should be capable of withstanding thermal shock; also it should have good heat-conducting properties. Copper, copper alloys, aluminum, aluminum alloys, steel, iron or steel alloys, and graphite are suitable, but do not exhaust the range of metals which may be used. It is desirable that the rollers be as clean and as uniform in surface condition as possible, to avoid hot spots. Some benefit is obtained by the use of a mold release silicone applied in a thin film when starting. In the casting of aluminum, this film must finally be cleaned off until substituted by an aluminum oxide coating produced in the casting process. Then a thin film of the mold release is again applied and left on. Other non-carbonizing oils may be used.
  • the range of metals which may be cast by the apparatus herein disclosed is primarily dependent upon the material employed in the ceramic nozzles, as it is essential that the nozzles be capable of withstanding the temperature of the metal in its liquid state and be inert to I the metal and not wetted thereby.
  • Strip speed (surface speed or roll- 56 per min.
  • the method of continuously casting metal is substantially as follows:
  • Molten metal is caused to flow through an enclosed ceramic conduit, fully isolated from air contamination, and is then caused to flow upwardly or upwell through a nozzle into a casting chamber at velocities below those which would produce turbulence; that is, laminar flow of the molten metal is maintained.
  • the molten metal is brought into heat-transferring relation with upwardly moving converging walls forming confironting sides of the casting chamber.
  • the surface speed of the converging walls is maintained at approximately the rate of upward flow of the molten metal. It is a feature of this method of continuous casting that the head of the molten metal be within the vertical heightof the casting chamber.
  • This method of continuously casting metal contemplates the further step of extracting heat from the moving walls, and moving the walls in paths which return to the casting chamber so that the walls on entering the region defining the casting chamber are chilled.
  • the step of extracting heat from the molten metal is conducted under conditions of substantial temperature differential between the moving walls and the molten metal, and the rate of convergence of the moving walls, particularly beyond the level at which complete solidification takes place, is at least equal to the rate of thermal contraction of the metal as to maintain maximum heattransferring contact therebetween.
