<p>PURPOSE:To further improve the product yield and the productivity by making concentrical circular groove type mold size coincide with the product of casting speed regulated with each mold radius by each cross sectional area of cast billet in all lines. CONSTITUTION:In a small cross section continuous casting device for molten metal 2 rotating a ring mold with endless groove opening an upper part in a horizontal direction, plural lines of groove molds are provided on concentric circles on a table and plural cast billets are cast at the same time and directly rolled. In the concentric circular groove mold size, at the time of using V (m/min) the casting speed regulated with each mold radius and S (m<2>) each cross section of the cast billet, the casting set so as to coincide with the product VS (m<3>/min) in all lines, is executed. By this method, integrated continuous rolling at the time of casting in multi-streams can be executed and trouble caused by the difference in casting speed between streams, can be eliminated and further, the stable casting of molten metal and rolling can be executed, and the product yield and the productivity can be improved.</p> |
