Title: Method and apparatus for cooling strip metal
IPC: B22D11/06
Filed: 1973-10-25
Abstract: 1454287 Casting composite articles F D TIMMERMANS 25 Oct 1973 [25 Oct 1972] 49844/73 Heading B3F [Also in Divisions C7 and F2] Molten metal 14, such as Pb, a Pb/Sn alloy or an alloy containing Pb and Al, is directed, as a coolant, against a lengthwise-moving strip 1, carrying a molten bearing alloy layer 2 comprising Cu, the molten coolant being directed in the same general direction of movement as the strip, e.g. at a similar speed, and either tangentially or at an angle to it according to whether the strip is in the form of a rotated hollow cylinder, as shown, or is flat and horizontal (Fig. 3, not shown). As shown, apparatus is tilted to cause flow of the molten coolant 14 from a reservoir 12 over a guide plate 15, on to the steel cylinder 1 rotating in a cooling chamber 11 into which it has been moved axially from a housing wherein the bearing layer 2 is cast centrifugally on the strip 1. The coolant 14 is returned, by reverse tilting, from a compartment 16 to the reservoir 12. To maintain the grain condition of the alloy layer 2 there may be an ultrasonic generator 21. The strip 1, having been heated to between 1100‹ and 1150‹ C., is cooled rapidly to below 400‹ C. to retain the homogeneous grain structure of the layer 2. A new cylindrical strip is inserted in the casting housing while the finished composite casting is lifted magnetically out of the cooling chamber 11. In the casting housing (9, Fig. 1, not shown), the temperature of the rotating cylinder is controlled, by apparatus responsive to the intensity or wavelength of light emitted, and the heating switched off after a time interval. After the initial cooling, and if a hot-rolling operation is not to be performed, the laminated strip may be further cooled, for tempering of either or both layers of the strip, by deep-frozen water particles (in the case of the cylindrical strip, blown into the cooling chamber 11 through slots 19 or a feed pipe 18) or by oil. For initial cooling of the flat strip (Fig. 3, not shown), an impeller throws molten Pb as coolant on to a guide plate and thence between inclined vanes, against the bottom of the strip whose top surface, carrying the alloy layer, passes under a housing filled with He, N 2  or H 2 . It then passes to a further housing for deep-frozen particles to be projected against the steel. The composite cylinder 1, 2 is machined in a water drum before or after pickling, then rolled and cut open as described in Specifications 1,262,160 and 1,292,216 (for the latter see Division B3) for obtaining flat strip for making semicylindrical sleeve bearings. The rear face of the strip may be milled and then rolled to obtain cold flowing of the steel.

In operation, the forwardmost terminal is positioned with its grip tongues 16, (18), Fig. 1 (not shown), under a bending die 36. The upper die set is lowered thereby bending the tongues upwardly as a pad 54 pivots downwardly against a spring 58. On raising the die set, the strip is advanced so that the bent tongues locate in a cavity in an anvil 46. The upper die set is again lowered and a blade 32 cuts out a neck (14) joining adjacent terminals, Fig. 1, before the die 34 crimps the tongues 16, (18). The tongue (18) is crimped about the wire 64 and the tongue 16, which is the longer of the two, is crimped about the wire insulation 66. A spring-loaded pad 38 holds the terminal during crimping and shearing.
