A method of manufacturing aluminum alloy sheet.

摘要

A method for manufacturing aluminium sheet stock includes hot rolling an aluminium alloy sheet stock, annealing solution heat treating without substantial intermediate cooling and rapid quenching. Molten metal is delivered from a furnace 1 to a degassing and filtering device 2. It is immediately converted to a cast feedstock 4 in a casting apparatus 3, whence it is moved through pinch rollers 5 onto hot rolling stands 6 and then to a heater 7. A quench station 8 follows the heater 7. After cold rolling the strip or slab 4 is coiled on a coiler 12. The caster 3 is shown in Figure 5 and has a pair of endless bells 20, 22 between which is formed a moulding gap supplied by a tundish 32. The bells 20, 22 are cooled by coolers 36, 38. <IMAGE>
