and by the following statement:-
This invention relates to apparatus for making continuous metal strip, particularly metal strips with an amorphous-molecular structure, by a method comprising depositing molten metal onto the moving surface of a chill body by forcing the metal through a slotted nozzle located in close proximity to the surface of the chill body 10 For purposes of the present invention, a strip is a slender body whose transverse dimensions are much less than its length, including ribbons and sheets, of regular or irregular cross section.
There has long been recognised the need for processes which would permit manufacture of finished or semi-finished products such as wire, ribbon or sheet directly from the molten 15 metal Hubert et al provided a review of such processes and classified then available technology into the "melt spin process" and the "melt drag process", lZeitschrift fuer Metallkunde 64, 835-843 ( 1973)l.
In the melt spin process, a jet of molten metal is cooled, either in free flight or by jetting it against a chill block, to obtain continuous filament Both of these embodiments employ a 20 pressurized orifice There is also a melt spin process operating without an orifice, wherein molten metal is supplied to a jet-forming device, such as a grooved spinning disc, to be expelled therefrom Hubert et al stated that the key to success in the melt spin process is to stabilize the liquid jet until it solidifies Jets of molten metal are inherently unstable since they have a strong tendency for droplet formation on account of the low viscosity and high 25 surface tension of molten metal Basic problems of jet stability have been discussed by Butler et al, in Fiber Science and Technology 5, 243-262 ( 1972).
In the melt drag process (British Patent Specification No 1160934), molten metal is made to form a meniscus held on by surface tension, at the outlet of a nozzle From this meniscus molten metal is then dragged onto a rotating continuous cooled drum or belt This method 30 avoids the difficulties of jet instablity inherent in the melt spin process Unfortunately, however, the speed of the moving chill surface in the melt drag process is severely restricted due to restriction in melt flow at meniscus, or else only discontinuous filament is obtained.
Also, it is believed that the melt drag process is not readily adaptable to provide sufficiently high rates of cooling of the molten metal to permit production of amorphous metal strips 35 Such strips require rapid quenching of certain molten alloys at a cooling rate of at least 104 C per second, more usually 106,C per second.
Continuous amorphous metal strips of narrow widths and thicknesses have heretofore been made by the melt spin process involving rapid quenching of a jet of molten metal directed against a moving chill surface, such as the inside or outside of a rotating roll, or a 40 moving belt The molten alloy jet which is to be quenched is stable due to its high velocity for a relatively short distance, say 3 to about 6 millimetres When it hits the rapidly moving chill substrate (velocity typically between about 1300 and about 2000 metres per minute) it wets it and forms a puddle That puddle is essentially stationary in space as the moving substrate draws it out into a strip, which is travelling at the same speed as the substrate In 45 2 1 592 257 2 actual application, it has been found that, using a single jet, the maximum width of strip so obtained from a jet of substantially circular cross section is limited to about 5 to 6 millimetres Attempts to provide wider strips by impinging a sheet-like jet against a moving chill surface met with little success, principally because the wide jet initially does not form a smooth line puddle as required to obtain a uniform, wide product, and consequently 5 produces kinky, non-uniformly quenched strip.
It is also possible to impinge a plurality of parallel, uniform jets properly spaced onto a moving substrate to form a relatively wide strip This approach, however, has inherent difficulties inasmuch as it requires a close matching of the jet velocities and spacings with the substrate speed The principal difficulty is that either the jets do not join together to 10 form a puddle, or the jets run together to form a ridge, so that, from a practical standpoint, it is difficult to obtain strips with uniform cross sections Moreover, since the molten metal puddle deposited by the jets onto the chill substrate tends to assume the equilibrium shape of a droplet, thick at the centre and thin at the edges, it is very difficult, if not impossible, to maintain a puddle of sufficiently uniform thickness for "drawing out" strips having even 15 approximately uniform cross section wider than about 7 5 mm.
In any event, it has not been possible to obtain wide metal strips, say wider than about 6 millimetres having isotropic strengths, by single or multiple jet casting procedures, that is to say having identical tensile strengths and elongation measured in the transverse as well as in the longitudinal direction, or in any direction therebetween, even though metal strips with 20 amorphous structures should be isotropic at least with respect to their tensile properties, and those with cast polycrystalline structures should be approximately isotropic Anisotropic tensile properties of wide strips of amorphous metal obtained by multiple jet casting procedure are believed to be caused by inherent imperfections in the strips obtained by that procedure Significantly, however, strips made by jet casting procedures, regardless of 25 width, lack uniformity of thickness, measured transversely, and they are prone to show significant variations in width along their length They lack such uniformity of thickness because they are drawn out from a puddle of liquid metal, which puddle has a strong tendency to assume the equilibrium shape of a droplet on account of the high surface tension of molten metal; they are prone to variations in width because even slight 30 unavoidable variations in the flow rate of the molten metal through the orifice to form the jet will cause variations in the diameter of the puddle with resultant variations in width of the strip drawn therefrom.
U.S P 3,862,658 to Bedell inter alia discloses a method for making amorphous strips (filaments) by ejecting molten alloy into the nip of two closely spaced counter-rotating steel 35 rolls This method provides for rapid, effective cooling of the melt, but involves rolling of the solidified strip between the steel rolls, as a result of which the product has anisotropic tensile properties By that method Bedell obtained an amorphous ribbon of 0 012 centimetres thickness and 1 27 centimetres width (Example 4 of U S P 3, 862,658).
It has been found that, if a thin uniform layer of molten metal is mechanically supported 40 on a chill surface using the apparatus of our invention, it becomes possible to draw out thin metal strips in the form of ribbons and sheets with aspect ratios (width/thickness) ranging from unity to any desired value, as below described.
Accordingly, in the present invention there is provided apparatus for making continuous metal strip from a melt comprising, in combination: 45 (a) a movable chill body providing a chill surface for deposition thereon of molten metal for solidification, means being provided for driving the chill body at a speed to provide longitudinal movement of said chill surface at a velocity of from 100 to 2000 metres per minute; and (b) a reservoir for holding molten metal, said reservoir including heating means for 50 maintaining the temperature of the metal above its melting point, said reservoir being in communication with (c) a nozzle having an orifice slot for depositing molten metal onto said chill surface, located in close proximity to said chill surface, the orifice slot being arranged generally perpendicular to the direction of movement of the chill surface, and being defined by a pair 55 of parallel lips, a first lip and a second lip numbered in direction of movement of the chill surface, wherein said slot has a width of from 0 3 to about 1 millimetre, measured in direction of movement of the chill surface, wherein said first lip has a width at least equal to the width of said slot, and said second lip has a width of from 1 5 to 3 times the width of said slot, wherein the gap between the lips and the chill surface is between 0 03 and 1 millimetre 60 and is from 0 1 to 1 times the width of said slot; (d) the apparatus being adapted to operate with means being provided for effecting expulsion of the molten metal contained in said reservoir through said nozzle for deposition onto the moving chill surface The length of the slot (measured perpendicular to the direction of movement of the chill surface) will determine the width of the strip or sheet 65 3 1 592 2573 being cast and, as a practical consideration, should not be longer than the width of the chill surface.
Means for effecting expulsion of the molten metal contained in the reservoir through the nozzle for deposition onto the moving chill surface in use of the apparatus include pressurization of the reservoir, such as by an inert gas, or utilization of the hydrostatic head 5 of molten metal if the level of metal in the reservoir is located in sufficiently elevated position.
