Abstract
A method of manufacturing strips, bars and wire rods comprises continuously supplying molten metal into an open-top endless casting groove on an annular mold that is rotated around a vertical shaft, cooling the molten metal in the casting groove from outside by forcibly cooling the annular mold, and continuously taking out the cast section from the casting groove at a point where a solidified shell has been formed throughout the entire circumference of the molten metal in the casting groove. A roll is provided upstream of the take-out point to depress the top surface of the cast section, thereby keeping the cast section in close contact with the surface of the casting groove. The cast section then slides diagonally upward over a surface inclined at an angle of 5 to 60 degrees that is provided on the exit side of the above roll in the casting groove. The annular mold may also have two or more concentrically disposed casting grooves to permit multi-strand casting of molten metal poured into the individual casting grooves. A multiple of sections thus simultaneously cast are then simultaneously rolled into finished products.
