Abstract
PURPOSE:To produce a cast billet without any cavity, etc., at good yield by drawing the cast billet from both end part of a mold horizontally arranged toward mutually reverse direction and drawing only from one direction after once stopping the drawing just before finishing the casting. CONSTITUTION:Molten steel 2 in a metal receiver 1 is supplied into the mold 9 horizontally arranged through nozzles 5, 6, 7 providing a stopper 4. Solidified shell 8' formed by cooling the molten steel 2 in the mold 9 is drawn toward mutually reverse direction as the cast billet 8 with pinch rolls 10 while cooling with sprays 12. In the above twin direction drawing type horizontal continuous casting machine, the drawing of the cast billet 8 is once stopped just before finishing the casting. As this stopping time it is desirable to wait for a time or more calculated by the equation t(min)=(Ds/25)<2> (wherein, Ds: shell thickness (mm) in cast billet to be born to drawing). By this method, after solidifying to the shell thickness in the cast billet to be born to drawing, the one end of the cast billet 8 is cut, and after that, it is drawn only from one direction.
