The casting device of strip can have various ways usually, as: be provided with one or two conveyer belt, do not establish conveyer belt and be provided with and form a slit between the opposite face of two rotation rollers, two rotation rollers, be provided with a rotation roller and a conveyer belt, a rotation roller perhaps only is set.All be provided with the mold of advancing in these casting devices, in the application's specification and claims, be referred to as " thin strip casting ".
When casting machine was provided with two rollers, the cast metal entered the gap by a special feed arrangement and solidifies in the gap or surface solidification at least, so that the metal sheet band of moulding can be handled.The general employing indirectly cooled off, and promptly water is sprayed directly on the opposite face inboard of the afterbody or the roller of conveyer belt, rather than is sprayed directly on the strip.Except said apparatus, can also adopt roller and a casting machine of being provided with a cavity to cast near the conveyer belt of cavity, the inboard of roller is by the water spray cooling, and the outside of conveyer belt is also by the water spray cooling.In single roll caster, the casting melt is positioned on the single roller that is not provided with cavity, and roller is from inner cooling, and cooling is only from a side of strip.Except twin-roll caster, single roll caster also may obtain extensive use in future.
In general, adopting thin strip casting is a kind of effective way that obtains semi-finished product and finished product as continuous casing, product can be in the form of sheets, thin ribbon shaped, wire or shaft-like, and founding materials can be ferrous metal and non-ferrous metals such as copper, aluminium, magnesium, nickel or its alloy such as steel.
