A layer of liquid parting agent, and any solid detritus contained therein, is completely removed from a casting surface of a rotating belt after contact with molten metal. A new layer of liquid parting agent is applied to the casting surface thereafter and prior to renewed contact with the molten metal. The removal of used parting agent and the application of fresh helps to prevent the formation of surface blemishes and defects on the cast metal strip product. Such blemishes and defects can also be minimized by using an injector having a flexible tip used to inject the molten metal onto the casting surface and preferably one or more spacers to create a gap between the tip and the casting surface itself. The spacer is preferably a screen of wire strands orientated to minimize disruption of the new layer of liquid parting agent applied to the casting surface. By avoiding disruption of the new layer of liquid parting agent, surface blemishes on the cast product are minimized.

A process of continuously casting metal strip, comprising: continuously injecting molten metal into a mould having at least one casting surface that is continuously recirculated through said mould, and removing a strip of solidified metal delivered from said mould, following cooling of said metal; continuously applying a layer of a parting agent uniformly to said at least one casting surface before said casting contacted surface is contacted by said molten metal in said mould; and continuously removing all of said parting agent, and any detritus contained in said parting agent, from said at least one casting surface after said casting surface emerges from said mould but before said surface undergoes application of further parting agent prior to further contact with molten metal in said mould; and further comprising injecting said molten metal into said mould from an injector having a flexible tip containing a discharge outlet for said molten metal, said tip conforming to the shape of said casting surface passing said tip. Apparatus for continuously casting metal strip, comprising: a mould for casting said metal strip, comprising at least one casting surface that, in use, is continuously recirculated through said mould; an injector for injecting molten metal into said mould; an applicator for applying a uniform layer of parting agent onto said casting surface prior to entry of said casting surface into said mould; and removal apparatus for substantially completely removing said parting agent, and any detritus contained therein, from said casting surface downstream of said mould but upstream of said applicator; said removal apparatus acting to prevent parting agent previously passed through said mould on said casting surface, and detritus contained therein, from contacting further molten metal injected into said mould; and wherein said injector has a flexible tip containing an outlet for said molten metal, said flexible tip conforming to the shape of said casting surface adjacent to said tip.
