A cold hearth furnace for refining of selected metals, such as titanium, is described. The furnace includes a melting hearth and a transport hearth arranged linearly. A pair of barriers partially block the flow of molten materials to mix it, allowing impurities to vaporize and preventing splattering of the material in the melting hearth from contaminating the final product.
L'invention décrit un four à sole froide servant à l'affinage de métaux choisis comme du titane. Le four comprend une sole de fusion et une sole de transport placée de façon linéaire à la première. Deux barrières bloquent partiellement l'écoulement du matériau en fusion afin de le mélanger, ce qui favorise la vaporisation des impuretés et empêche que des éclaboussures de matériau dans la sole de fusion ne contaminent le produit final.
