One step, the positioning for the bearing 6；The outer ring of the roller 7 and the bearing 6 is consolidated by holding down bolt 5
Even；The inner ring of the built-in water pipe 2 and the bearing 6 positioned at the both ends of roller 7 is interference fitted, and the built-in water pipe 2 is worn
Cross the end cap 9；One end of the built-in water pipe 2 connects the nozzle 1, and the other end of the built-in water pipe 2 connects the water
Interface tube 12, the waterpipe jointing 12 connect the moccasin water pipe 15；The end cap 9 passes through end cap fixing bolt 14 and packing ring 8
The both ends of the roller 7 are connected to, the bearing 6 is placed in inside the roller 7.
The motion bracket mechanism includes nut 3, support 4, annulus 10, flat key 11 and pulley 13；The annulus 10 passes through
The nut 3 and flat key 11 are connected with the roller 7, and the support 4 welds with the annulus 10 and pulley 13.
Inner surface on-line cooling device proposed by the present invention for hot rolled seamless steel tube production, with conventional steel pipe surface
Face cooling device is used cooperatively, and achievable hot rolled seamless steel tube rolls rear online accelerated cooling process, improves mechanical properties of pipe.
