Abstract
The invention concerns a process for cleaning the surface of cast strip produced on continuous casting machines, and concerns in particular strip of aluminium, zinc or their alloys. The cast strip is formed between two endless strip molds which are spaced apart and are provided at least in part with a protective layer in the form of a particulate material. Particles of the protective layer adhering to the cast strip are removed from the strip by spraying with water under pressure immediately after the strip solidifies, on leaving the mold.

A process for cleaning the surface of a cast strip composed of a metal selected from the group consisting of aluminum, zinc, and alloys thereof and manufactured between two spaced apart continuous strip molds each having at least a portion of a protective layer comprising particulate material, said process comprising the step of:
- spraying said cast strip with water under pressure immediately after said cast strip solidifies after it is removed from said casting molds, said cast strip having a width up to 2000 mm and a thickness between 10 to 35 mm and said spraying being carried out with a jet stream of water delivered at the rate of 200 to 1000 liters per minute at a pressure of 2 to 300 atm, whereby particulate matter adhering to said cast strip is removed therefrom.
