PROCEDE ET INSTALLATION POUR LA FABRICATION DE TUBES SANS SOUDURE
Ingots hot from rolling are pierced to form a hollow ingot by means of an internal tool of a press or skew-rolling line, and are subsequently elongated to form a tubular bloom by a stretching unit provided with a mandrel rod, and are finally finish-rolled. When inserting or withdrawing the internal...

| description | Ingots hot from rolling are pierced to form a hollow ingot by means of an internal tool of a press or skew-rolling line, and are subsequently elongated to form a tubular bloom by a stretching unit provided with a mandrel rod, and are finally finish-rolled. When inserting or withdrawing the internal tool into or out of the hollow ingot or the mandrel rod into or out of the tubular bloom, inert gas is introduced into the freed interior space in order to prevent scaling of the interior wall of the tubular bloom. |
