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

A sheet mill table roll in the form of a cylindrical hollow body having hubs therewith fixed therewith on half-axles mounted in table bearing supports. Each end face of the cylindrical hollow body has a coaxially mounted cover with a central port. The diameter of the central port is essentially smaller than the outside diameter of the hub which is fitted with through channels running at its periphery. The covers form with said half-axles annular slots for the passage of cooling fluid through the interior of the roll body.

Sheet mill table roll

A device adapted for the production of a hollow body with an extension in a built-up metal mould provided with lining. The spinning axis of the built-up metal mould is essentially coaxial with the mould longitudinal axis owing to which the filling of the cavity provided in said mould with molten metal causes a progressing unbalance of the device. For offsetting this unbalance provision is made for a movable weight travelling radially to the spinning axis of said metal mould as the unbalance is being progressed.
