Definitions

  • the present invention relates to strip casting apparatus for the casting of strip material at high quench rates and at high production. rates. More particularly, the present invention is directed to apparatus for rapidly casting thin metallic strip material.
  • United States Patent No. 4,142,571 is particularly directed to a slot construction in a metal strip casting nozzle having stringent dimensional requirements.
  • United States Patent No. 4,007,462 pertains to the provision of a specific construction for a stationary housing above the peripheral surface of a chill roll used for strip casting.
  • melt spinning processes of producing metallic filament by cooling a fine molten stream either in free flight or against a chill block have been practised.
  • melt extraction techniques such as crucible melt extraction disclosed in United States Patent No. 3,838,185, pendant drop melt extraction techniques taught in United States Patent No. 3,896,203 and splat cooling explained in United States Patent No. 3,297,436. It has been found difficult to produce uniform sheet or strip by such alternative techniques of rapid quenching. There are many factors, such as casting temperature and pressure, auxiliary surface cooling rates, surface coatings for the casting surface, and the like which appear to affect the product thickness, the quality and the reproducibility of rapidly cast strip material.
  • strip casting is not a widely accepted and commercially significant operation at the present time. It appears that various improvements, modifications and/or innovations are required in the art before there is likely to be any significant commercial impact in the art of strip casting.
  • proper relationships among such variables as molten metal tundish construction, nozzle orifice size and dimensions, spacing from a casting surface,.speed at which such surface is moved, quench rates, metal temperature and feed rates, and the like may require more accurate identification and interrelation in order to accomplish the uniformity and consistency required for successful, commercial production of cast strip.
  • certain nozzle structures and their dimensional relationship to the casting surface onto which strip material is cast have been found to be desirable to yield uniform strip casting results when utilized in various casting parameters.
  • the present invention has as an object thereof the provision of a strip casting apparatus which is capable of continuously casting metallic strip material of substantially uniform dimension and substantially uniform quality throughout its length.
  • Another object of the present invention is'to enable the provision of a strip casting apparatus having a nozzle construction which promotes the efficient rapid casting of metal strip material with a minimum of'metal turbulence during casting.
  • Another object of the present invention is to provide a strip casting apparatus capable of reproducing successful strip casting operations.
  • Another object of this invention is to provide a strip casting apparatus which can effect sufficiently rapid quenching of the produced strip to result in the production of amorphous strip.
  • a strip casting apparatus which can effect sufficiently rapid quenching of the produced strip to result in the production of amorphous strip.
  • continuously cast crystalline material is equally comprehended by the present invention.
  • a further object of this invention is to identify certain design and dimensional requirements, particularly with regard to nozzle structure, which permit continuous and repetitious rapid casting of metallic strip material of uniform dimension and uniform quality.
  • the present invention'provides. apparatus for continuously casting metal strip comprising:
  • Figure 1 generally illustrates apparatus according to the present invention for casting metallic strip material 10.
  • This apparatus includes a casting drum, wheel, belt, or the like upon which the strip 10 is cast.
  • a continuous strip 10 is cast onto a smooth, outer peripheral surface 14 of a circular drum or wheel 12 as shown in Figure 1.
  • a wheel with a smooth, frustoconical outer peripheral surface may be employed.
  • a belt capable of rotating through a generally ovular path may be employed as the casting element.
  • the casting surface 14 should be cooled to a temperature below the solidus temperature of the metal being cast and should be at least as wide as the strip to be cast.
  • the casting surface 14 comprises.the surface of the water cooled, precipitation hardened copper alloy wheel 12 containing about 98% copper with about 2% chromium. Copper and copper alloys are preferable because of their high thermal conductivity and wear resistance. However, berillium copper alloys, steel, brass, aluminum, aluminum alloys or other materials may be utilized alone, or in combination. For example, multipiece wheels having outer peripheral sleeves of molybdenum or other material may be employed. Likewise, cooling may be accomplished with the use of a medium other than water. Water is typically chosen for its low cost and its ready availability.
  • the surface 14 of the casting wheel 12 must be able to absorb the heat generated by contact with molten metal at the initial casting point 16, and such heat must be conducted substantially into the copper wheel during each rotation of the wheel.
  • the initial casting point 16 refers to the approximate location on the casting surface 14 where molten metal 20 flowing from a crucible or tundish 22 contacts the casting surface 14.
  • Cooling, by heat conduction, may be accomplished by delivering a sufficient quantity of water through internal passageways located near the periphery of the casting wheel 12. Alternatively, the cooling medium may be delivered directly to the underside of the casting surface. Understandably, refrigeration techniques and the like may be employed to accelerate or decelerate cooling rates, and/or to effect wheel expansion or contraction during strip casting.
  • the casting surface should be generally smooth and symmetrical to maximize uniformity in strip casting.
  • the distance between the outer peripheral casting surface 14 and the surfaces defining the orifice passage of the nozzle which feeds the molten material onto the casting surface 14 must not deviate from a desired or set distance during the casting operation. This distance shall hereinafter be called the standoff distance or gap. It is understandable that the gap should be substantially maintained throughout the casting operation when it is the intention to cast uniform strip material.
  • the molten material 20 to be cast in the apparatus described herein is preferably retained in the crucible or tundish 22, which is provided with a discharge nozzle.
  • the nozzle is typically, though not necessarily, located at a lower portion of the tundish 22, as shown in Fig 1, and the nozzle 24 comprises a curvilinear element 24 mounted in the tundish 22.
  • the curvilinear element 24, located in or forming a lower portion of the tundish 22 is best shown in the tundish 22 in Figure 2, and in perspective view in Figure 3.
  • an orifice passage 30 is preferably substantially centrally located in the nozzle element 24.
  • Such approximate central location of the orifice passage, or slot, 30 helps to assure uniformity as the pressure of the molten metal bearing thereagainst is substantially equalized during the casting operation. It should be understood, however, that the slot may be located in off-center positions as may be desired.
  • the longitudinal extent of the orifice passage 30 should approximate the width of the strip to be cast. There does not appear to be a limitation on the longitudinal extent of the orifice passage, and, passages as long as 915mm (thirty six inches), or longer, in a curvilinear element may be used. It is highly desired that the molten metal flow uniformly through the orifice passage 30 in the curvilinear nozzle element 24 in order to form uniform, high quality strip material. In an alternative embodiment, strip of various widths may be produced by cutting'multiple longitudinally aligned orifice passages 30 of appropriate longitudinal extent in the curvilinear element 24 forming the nozzle of a tundish 22, as opposed to a single orifice passage 30.
  • each passage 30 should be substantially uniform throughout the longitudinal extent thereof to produce strip material having uniform dimensions.
  • the cooled casting surface 14 moves past the orifice passage 30 in a direction substantially perpendicular to the longitudunal axis of the passage 30.
  • the orifice passage 30 is defined between a first side portion 32 and a second side portion 34 of the curvilinear element 24.
  • the first side portion 32 is located on the downstream side of the. orifice passage 30, with respect to the direction of movement of the casting surface 14 indicated by the arrow in Figure 4.
  • the first side portion 32 has an inside surface 36 which preferably, is substantially planar, and an outer lip projecting surface 38 disposed toward and facing the casting surface 14.
  • the outer lip projecting surface 38 is relieved, such as at 40, to define a lip projection 42.
  • the second side portion 34 is located on the upstream side of the orifice passage 30, with respect to the direction of movement of the casting surface 14 indicated by the arrow in Figure 4.
  • the second side portion 34 has an inside surface 46, which.preferably, is substantially planar and, also preferably, is substantially parallel -to and facing the inside surface 36 of the first side portion 32 at least at an outer portion of the orifice passage 30 with respect to the direction of metal flow from the tundish 22 through the passage 30.
  • a bottom surface 48 of the second side portion 34 is disposed toward and facing the casting surface 14.
  • the outer lip projecting surface 38 of the first side portion 32 and a portion of the bottom surface 48 of the second side portion 34 are in substantially complete parallelism with the casting surface 14 movable therebelow.
  • substantially complete parallelism may be accomplished by placing a sheet of sandpaper l or the like, against the casting surface 14 with the grit side of the sandpaper facing the curvilinear element.
  • the outer lip projecting surface 38 of the first side portion 32 and the bottom surface 48 of the second side portion 34 are ground by the grit side of the sandpaper into substantially complete parallelism with the casting surface 14.
  • Such parallelism may be achieved on most refractory nozzles, even when round or other curvilinear casting surfaces are employed. To achieve such parallelism by this procedure 400 or 600 grit sandpaper has been found to be adequate.
  • the standoff distance, or gap h between the outer lip projecting surface 38 and the casting surface 14 may be maintained throughout the length of the projection 42. It has been found-that the gap h between the outer lip projecting surface 38 and the casting surface 14 must be maintained at less than about 3.048mm (0.120 inch) in order to successfully cast strip material. Preferably, this gap h is maintained at less than about 2.032mm (0.080 inch) and for casting certain alloys into thin gauge strip, a gap h of less than 0.254mm (0.010 inch) is preferred. It has also been found that the gap h between the bottom surface 48 of the second side portion 34 does not appear to be as critical.
  • the inside surface 46 thereof extend toward the casting surface 14 while parallel to the inside surface 36 of the first side portion 32, at least in an outer portion of the orifice passage 30, so as not to interfere with the maintenance of a stable flow of molten metal through the passage 30 in the curvilinear element 24 and onto the moving casting surface 14.
  • the bottom surface 48 of the second side portion 34 may just clear the casting surface 14, i.e. be within about 0.0508mm (.002 inch) thereof as shown in Figure 7, or alternatively, the bottom surface 48 may be tapered from the orifice in a direction away from the casting surface 14, as shown in Figure 8. In any event, the gap h between the bottom surface 48 of the second side portion 34 and the casting surface 14 must be sufficiently restricted at the nozzle to prevent significant molten metal backflow therebetween during casting.
  • the inside surface 36 of the first side portion 32 extends through a curvilinear surface 50 to the outer lip projecting surface 38, rather than through the abrupt 90° juncture shown in Figure 4.
  • Providing such radiused corner surface 50 has been found beneficial in the production of certain grades of strip material. More particularly, such radiused corner surface 50 helps minimize nolten metal turbulence during strip casting and, therefore, results in more uniform production parameters. It has alsc been found that a sharp corner between the inside surface 36 and the outer lip projecting surface 38 may be subjected to various pressures and flow patterns which ould create stress conditions for curvilinear elements 24 made of certain materials and, in some instances, may break, crack or wear during casting thereby upsetting balanced strip casting conditions. Providing such rounded corner surface 50 may minimize the adverse affects of such turbulence and metal flow through the curvilinear element 24 comprising the nozzle of the tundish 22.
  • an inside portion of the orifice passage 30 may be relieved, or tapered.
  • both the first side portion 32 and-the second side portion 34 may be cut into a V-shape, or a more rounded U-shape at an inside portion thereof, creating an initial funnel type structure, which further maximizes uniformity in metal flow patterns and minimizes irregularities or turbulence during strip casting.
  • Another preferred arrangement which minimizes molten metal turbulence during strip casting, is to arrange the curvilinear element 24 at an angle such that the metal is fed in the same direction as the casting surface 14. This may be accomplished by disposing the inside surfaces 36 and 46, defining the orifice passage. 30, toward the casting surface 14 at an angle of less than about 90°, or preferably at an angle of about 45.
  • the flowing molten metal is not subjected to as severe a change in flow rate as would be experienced by arranging the orifice passage 30 to feed molten metal perpendicular to the casting surface 14.
  • the crucible 22 is preferably constructed of a material having superior insulating ability. If the insulating ability is not sufficient to retain the molten material at a relatively constant temperature, auxiliary heaters such as induction coils may have to be- provided in and/or around the crucible 22, or resistance elements such as wires may be provided.
  • a convenient material for the crucible is an insulating board made from fiberized kaolin, a naturally occurring, high purity, alumina-silica fire clay. Such insulating material is available under the trade name Kaowool HS board.
  • various other materials may have to be employed for constructing the crucible 22 or the curvilinear element 24 including graphite, alumina graphite, quartz,.clay graphite, boron nitride, silicon nitride, silicon carbide, boron carbide,alumina,zirconia and various combinations or mixtures of such materials. It should also be understood that these materials may be strengthened; for example fiberized kaolin may be strengthened by impregnating with a silica gel or the like.
  • the orifice passage 30 of the curvilinear element 24 may be open and its configuration remain substantially stable throughout a strip casting operation. It is understandable that the orifice passage 3 0 should not erode or clog, significantly, during a strip casting operation or the primary objectives of maintaining uniformity in the casting operation and of minimizing metal flow turbulence in the tundish 22 may be defeated. Along these lines, it appears that certain insulating materials may not be able to maintain their dimensional stability over long casting periods. To obviate this problem, side portions 32 and 34 forming the orifice passage 30 of the curvilinear element 24 may be constructed of a material which is better able to maintain dimensional stability and integrity during exposure to hiqh molten metal temperatures for prolonged time periods.
  • Such materials may take the form of a single, generally semi-circular element 24 with a slot 30 cut therethrough as shown in Figure 3.
  • the curvilinear element 24 may comprise a pair of facing inserts held in the crucible 22 to form a slot 30 therebetween as shown in Figure 6.
  • the orifice passages 30 in single curvilinear element 24 may be cut ultrasonically to ensure that the desired slot dimensions are accurately provided.
  • Such curvilinear elements 24 may be constructed of materials such as quartz, graphite, clay graphite, boron nitride, alumina graphite, silicon carbide, stabilized zirconia silicate, zirconia magnesia, alumina, or other similar molten metal resistant materials. These curvilinear elements 24 may be held in the crucible 22 mechanically, and/or with the aid of adhesives such as various refractory cements.
  • the drive system and housing for the drum wheel or other casting surface 14 of the present invention should be rigidly constructed to permit drum rotation without structural instability which could cause the drum to slip or vibrate. In particular, care should be taken to avoid resonant frequencies at the operating speeds for the casting surface 14.
  • the casting surface 14 should be capable of moving at a surface speed of from about 61 linear surface metres (200 linear surface feet) per minute to more than about 3048 linear surface metres (10,000 linear surface feet) per minute. When utilizing a drum having a circumference of about 2.44 metres (8 feet), this rate calculates to a drum speed from about 25 rpm to about 1250 rpm.
  • a three horsepower variable speed reversible, dynamically braked motor provides an adequate drive system for an integral copper alloy casting drum about 50.8mra (2 inches) thick and about 2.44 metres (8 feet) in circumference.
  • the casting surface 14 on the wheel or drum of the apparatus of the present invention is smooth. It has been found that in certain applications, such as for producing amorphous materials, finishing the peripheral surface 14 of a casting drum 12 with 400-grit sandpaper and preferably with 600 grit sandpaper may yield improved product uniformity.
  • the crucible 22 is constructed of an insulating board, such as Kaowool HS Board,and the curvilinear element 24, as shown in Figure 3, is made of clay graphite, a molten metal resistant material, held in the walls of the crucible 22.
  • the orifice passage 30 is cut ultrasonically in the clay graphite element 24.
  • the first side portion 32 and the second side portion 34 of the curvilinear element 24 define the orifice passage, or slot, 30 therebetween.
  • curvilinear element 24 a plate-made of quartz or vycor material, which are highly molten metal resistent materials, having a width such as about 38mm (one and one half inch) may be bent around an appropriate small radius, as shown in the drawing.
  • the curvilinear element 24 may comprise cast boron nitride.
  • the desired slot forming the orifice passage 30 in the curvilinear element 24, may be accurately cut therein with an ultrasonic drill.
  • a preferred one piece, curvilinear element 24, as best illustrated in Figures 2, 3 and 4 may be constructed of a semi-circular ring of molten metal resistent material.
  • a slot b having a width of about 0.254 mm to about 2.032mm (0.010 to about 0.080 inch) between parallel inside surfaces 36 and 46 may be ultrasonically drilled into a clay graphite insert material, and the insert may be mounted into the crucible 22 as shown in Figure 2. It should be understood that the design of the outer, peripheral edges of such curvilinear element nozzle may be modified to assist in holding the curvilinear element 24 in the walls of the crucible 22.
  • a preferred orifice passage 30 in the curvilinear element 24 of the apparatus of the present invention is shown in enlarged cross-section in Figure 4.
  • the dimensions indicated in Figure 4 may have the following preferred limitations.
  • the width b of the orifice passage 30 is typically in the range of from about 0.254 to about 1.016mm ( about 0.010 to about 0.040 inch). In the production of crystalline strip material, such as stainless steel, the width b of the orifice passage 30 may be greater, perhaps as high as about 2.032mm (0.080 inch) if thick strip is being uniformly produced.
  • Dimension e representing the cross-sectional thickness of the curvilinear element 24, f, representing the width to which a top portion of the orifice passage 3 0 may be relieved, and 9, representing the depth to which a top portion of the orifice passage 30 may be relieved, appear to be somewhat arbitrary.
  • Molten metal turbulence during strip casting may be minimized, and perhaps avoided by relieving sharp corners of the nozzle in the direction of/casting.
  • corner relief such as radiused corner surface 50 shown in Figure 5
  • eroding material such as Kaowool HS board
  • Turbulence may also be avoided by completely rounding the corner 50 of the projection 42 on the first side portion 32 of the curvilinear element 24 as is shown in Figure 5 during or after manufacture thereof.
  • molten metal is delivered to a heated crucible 22.
  • a heater such as induction coils of resistence wire
  • the molten metal may be poured directly into a preheated crucible.
  • the preheat temperature should prevent freezing or clogging of the orifice passage 30 during the initial casting operation, and the temperature of the flowing metal should thereafter keep the crucible 22 and curvilinear element 24 forming the nozzle at sufficient temperature to ensure uninterrupted molten metal flow through the orifice passage 30.
  • the curvilinear element 24 may be externally heated throughout the casting operation.
  • the metal which is fed to the crucible 22 may be superneated to allow a certain degree of temperature loss without adversely affecting metal flow through the orifice passage 30.
  • a metallostatic head height in the tundish 22 should be maintained at a relatively constant level, typically less than 254 mm (ten inches) above the orifice passage 30, throughout the casting operation to assure that a relatively constant static head pressure may be maintained at the orifice passage 30.
  • This may be accomplished by initially pouring the molten metal 20 into the crucible 22 to the desired height and thereafter controlling the rate at which additional molten metal 20 is poured into the crucible 22 to maintain the desired metallostatic head. It is understandable that the rate at which additional molten metal 20 is fed to the crucible 22 should be in substantial conformity with the rate at which metal flows from the -orifice passage 30 onto the casting surface 14 in forming strip material 10.
  • tundish or crucible 22 similar to that shown in Figure 1, made of a commercially available tundish material available under the trade name Garnex, a casting run was made on Type 304 stainless steel.
  • the orifice passage 30 at the base of the crucible was about 33.02mm (1.3 inches) long and 2.032mm (0.08 inch) wide, and the distance,or gap,between the outer, lip projecting surface 38 and casting surface 14 was between 0.508 to 1.016mm (0.02 to 0.04 inch), With.
  • doctor blade has been found particularly useful in the production of thinner amorphous strip materials which appear to have a greater tendency to adhere to the casting surface 14 than do the crystalline strip materials. It is believed that the force which retains the strip on the casting surface may reflect the quality of the thermal contact between the strip 10 and the casting surface 14. Alternative arrangements, such as an air knife, may also be employed to separate the strip 10 from the wheel 12.
  • a relatively high quality strip material including amorphous material which for the purpose of this invention includes materials which are at least 25% amorphous, is feasible and practical using the apparatus and procedures described above. Understandably,the quench rates must be higher for amorphous material as compared to similar gauge crystalline strip material. Quench rates may be accelerated such as by increasing the speed of the casting surface 14, or the like. It is important to recognize that the process may be conducted in two effective modes. With the orifice passage 30 quite close to the casting surface 14 as measured between the outer lip projecting surface 38 and the casting surface 14, strip perhaps 0.025 to 0.0762mm (0.001 to 0.003 inch) thick can be cast of either amorphous or crystalline materials.
  • the quench rate may be significantly lower due at least in part to the increase in the product thickness.
