ABSTRACT:
The present invention is intended for the production of long, large diameter tubular blanks (over 5 m in length and over 800 mm in diameter). According to the method, positive pressure of an inert gas is created inside a spinning mold and maintained there in the process of pouring molten metal thereinto. That provides for the equal speeds of the mold rotation and the metal movement within the mold, and thereby promotes the production of tubular blanks with a uniform structure.
