ABSTRACT:
A method and apparatus for the direct casting of steel slabs for subsequent processing instead of casting ingots and then reducing them to slabs, blooms or billets. A flat elongated casting cavity is formed by an assembly of mold components to define a slab. Prior to casting, this mold is inclined at an angle of about 3.degree. to the horizontal with the bottom end of the casting cavity higher than the pouring end. The molten metal is poured through a sprue attached to the mold assembly adjacent the pouring end. The sprue provides a reservoir for molten metal at a level above the bottom end of the casting cavity so that the casting cavity is completely filled during pouring. When pouring is completed, the mold assembly is promptly tilted to an upright position with the pouring end and sprue at the top. The reservoir of molten metal in the sprue acts as a riser and the sprue is movable so that it follows the shrinking slab and continues to feed molten metal to the casting cavity to compensate for shrinkage during solidification. When the metal solidifies, the mold is disassembled to remove the slab thus cast. The size of the slab can be changed within the limits of the outside mold by moving or changing the thickness of end blocks and side blocks.
