ABSTRACT:
A method and apparatus for the casting of metals in which a molten stream of metal is atomized into a spray of highly liquid droplets. The droplets are deposited on a moving substrate such as an endless belt provided with side dams. The droplets flow in a direction transverse to the direction of movement of the substrate and are contained by the side dams. The droplets may have an average size of 300 microns and the spray may have a liquid to solid ratio of at least 50%. This arrangement overcomes the problems of splashing and turbulence caused by the relative flow between the melt and the belt in regular belt casting and overcomes porosity problems associated with spray casting.
