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.

Method for centrifugal casting of tubular metal blanks

Disclosed is a flux intended for use in centrifugal casting of bimetallic pipes and comprising calcium oxide, silicon oxide, boron oxide, sodium oxide and sodium fluoride, said components being contained therein in the following amounts:

Flux for use in centrifugal casting of bimetallic pipes

An installation for producing bimetallic solid bodies of cylindrical shape comprises a movable base which, together with a runner means is adapted to eliminate a clearance between the runner means and a casting mould having a stationary horizontal axis of rotation.
