Production unit for hot-rolled seamless steel tubes

The utility model relates to a production unit for hot-rolled seamless steel tubes which comprises a tube billet band-sawing machine processing section. An annular heating furnace is connected with a tail end of the tube billet band-sawing machine processing section. A guide outlet of the annular heating furnace is connected with a two-roller skew-rolling pipe rolling mill through a tapered roller puncher. The two-roller skew-rolling tube rolling mill is connected with a cooling bed through a three-roller sizing mill. The other end of the cooling bed is provided with a six-roller straightener and a tube cutting machine. Tube billets are manufactured into finished products through processes of being sawn by a tube billet band-sawing machine, being heated by the annular heating furnace, punching and manufacturing of hollow billets by the tapered roller puncher, rolling of pieced billets by the two-roller skew-rolling tube rolling mill, being sized by the three-roller sizing mill, being cooled by the cooling bed
