RZJ90 Hot Rolling Seamless Pipe Production Line
There are many disadvantages for methods of production like laggard technics, timeworn technical equipments and high energy consumption, heavy pollution but low efficiency. However, hot rolling seamless pipe product line has not only overcome above disadvantages but also have some advantages. For example, it is not necessary to pickling, phosphoroused and saponification; it is without chemical pollution; low investment of machines; high precision of finished tube; short of processes; heat one time then continuous producing and achieve final production. Therefore, it is applied widely.
Production technique flow is as follows: billet cutting --- inspection and grinding --- billet centening --- billet heating --- two-roller horizontal cross rolling piercer --- two-roll A-R elongator with mandrel retained --- three-roller sizing mill --- large and small cooling bed --- nine-roller vertical pipe straightener --- grinding and testing --- cutting --- inspection and marking --- packing --- weighing --- warehouse
