Abstract
Disclosed is a method and apparatus for making a molten film of metal, steel, in particular a steel film, more uniform, by strip casting, in which the molten material which is applied to a revolving belt is to have a thickness and properties which are as uniform as possible across the width of the strip. To make the strip more uniform over its width, forces are introduced into the metal film with a component which is perpendicular to the direction in which the strip is conveyed, which forces make the profile of the molten film of metal more uniform.

A method for making a molten film of metal produced by strip casting having substantially uniform thickness and properties over the width of the strip, comprising:
- applying a molten metal material to a revolving belt to form a metal film;
- and introducing forces into the metal film opposite to the direction of flow of the metal film at an angle of between 0 and 80° with respect to the vertical, wherein the forces are applied by means of a gas stream which is directed oppositely to the direction in which the strip is conveyed and the gas stream impinges on the surface of the film of metal at a speed so as to produce an indentation of at least half the thickness of the film of metal in the liquid metal at the point of incidence.
