Abstract
A casting belt for using in a single-belt or twin-belt casting apparatus is disclosed. The casting belt is made of aluminum alloy such as an alloy from the AA5XXX and AA6XXX systems, preferably having a thickness in the range of 1 to 2 mm. The aluminum casting belt of the invention is suitable for casting non-ferrous and light metals such as aluminum, magnesium, copper, zinc and their alloys, especially aluminum alloys such as Al—Mg, Al—Mg—Si, Al—Fe—Si and Al—Fe—Mn—Si alloy systems. A belt casting machine and process using the aluminum casting belt of the invention are also disclosed.
Claims17
A continuous belt casting apparatus for continuously casting metal strip, comprising:
- at least one movable endless belt having a casting surface at least partially defining a casting cavity,
- means for advancing said at least one endless belt through the casting cavity,
- means for injecting molten metal into said casting cavity, and
- means for cooling said at least one endless belt as it passes through the casting cavity,
- wherein said at least one endless belt is made of aluminum or an aluminum alloy.
A process of casting a molten metal in a form of strip, which comprises:
- providing at least one casting belt made of aluminum or an aluminum alloy and having a casting surface which at least partially defines a casting cavity, continuously advancing said at least one casting belt through the casting cavity, supplying the molten metal to an inlet of the casting cavity, cooling said at least one casting belt as it passes through the casting cavity, and continuously collecting the resulting cast strip from an outlet of the casting cavity.
