Abstract:
A method of continuous casting of a molten aluminum bearing alloy in which a casting space is defined between substantially parallel opposed portions of a pair of traveling endless belts and the molten aluminum bearing alloy is supplied into the casting space to be continuously cast into the shape of a plate, the method comprising:air-spraying the plate as it emerges from the casting space; water-spraying said plate downstream from said air-spraying; preventing water from contacting said plate after it has emerged from the casting space upstream from said air-spraying, by preventing splashing of water from the downstream water-spraying; and controlling said water-spraying to provide a cooling rate &Dgr;T during solidification of the aluminum bearing alloy so that the cooling rate &Dgr;T ranges between 3 and 6Â° C./sec. where &Dgr;T=(Tâˆ’500)/t, T is a temperature when the casting of the aluminum bearing alloy starts, and t is a time in sec. between start of casting and the cooling time when the temperature of the aluminum bearing alloy decreases to 500Â° C., thereby providing a cooled plate containing a multi-element inter-metallic compound of at least Alâ€”SIâ€”Fe having a particle size of 40-55 &mgr;m.
