Abstract

A plant for manufacturing seamless steel tubes has a heating furnace for heating ingots which may be of square cross section, a piercing press for piercing the ingots to produce pierced circular section blanks, at least one roughing push bench immediately beyond and in alignment with the piercing press and a finishing push bench for producing a semi-finished tubular product suitable for subsequent skew-rolling.
