Abstract
A process for improving the surface condition and thickness regularity of a thin metal strip cast on a rotating wheel by injection of a molten metal having a free surface forming a meniscus in contact with the wheel. The process comprises detecting undulations or variations in thickness of the strip of at least 10 .mu.m, forming a gas cushion above the free surface utilizing a porous body disposed facing the free surface, and adjusting the pressure of the gas cushion, the location of the porous body or both to control the variations or undulations.
