Abstract

"PROCESSO PARA CRISTALIZAçãO FRACIONADA DE UM METAL". A presente invenção refere-se a um processo para cristalização fracionada de um metal fundido no máximo parcialmente solidificado, no qual a camada de metal fundido no máximo parcialmente solidificado possuindo uma superfície superior e uma superfície inferior é dividida em uma série de compartimentos comunicando-se entre si, no qual o metal é agitado em pelo menos alguns dos compartimentos e no qual os cristais formados elou existentes na camada de metal são seletivamente transportados em uma direção predeterminada e o metal fundido é seletivamente transportado na direção oposta.
