Abstract

1318607 Making seamless tubes CEFILAC 24 Sept 1970 [25 Sept 1969] 45646/70 Heading B3A Tubes are made from steel bars of square or rectangular cross-section issuing from a continuous casting plant, before substantial cooling has taken place, by cutting the bars into billets of predetermined weight, heating the billets to deformation temperature, i.e. 1000-1250‹ C, 1830-2280‹ F., and transforming them into hollow blanks of circular cross-section in an upsetting piercing press and extruding the blanks into long tubes with substantially the desired final wall thickness. The tube diameter may be subsequently reduced in a stretch reducing mill.
