I. Hot rolling procss


1. Billet preparation: including tube blank storage, tube blank inspection, surface cleaning, tube blank cutting and cold centering;


2. Billet heating: the billet is heated in heating furnace and then transport it on piercing mill;


3. Piercing: Perforation is to pierce a solid tube blank into a hollow capillary tube. The internal and external surface quality of the capillary tube and the uniformity of the wall thickness will directly affect the quality of the finished product. Therefore, the method of perforation is very important;


4. Elongating: Elongating is to thin the wall thickness of the perforated capillary tube to achieve the required thermal size and uniformity of the finished tube. Elongating is the main extension process of tube making. Its selection and the reasonable matching of deformation with the piercing process are the key to determining the quality, output and technical and economic indicators of the unit.


5. Sizing: Sizing is the final finishing process of the capillary tube, so that the capillary tube can obtain the required outer diameter thermal size and precision of the finished tube.


II. Advantages of hot rolling line:


  With both technical process and relevant hot rolling equipments of steel pipe industry have improved, during producing, no need pickling, phosphorization and saponification, so it hasn’t chemical pollution; it also has low investment, high precision of finished tube, short manufacturing process, it just need to heat one time and then continuous manufacturing until achieve finial production. It has been employ widely nowadays.
