Heating temperature of tube billet for seamless tube

Tube billet heating temperature for the seamless tube manufacturer refers to the tube blank discharge temperature. It should be determined to ensure that the steel is subjected to the main deformation within the best range of plasticity. The basis for determining the heating temperature is the iron and carbon balance diagram. In practice, the following factors should generally be considered.

1. Steel grade. Different steel grades correspond to their different heating temperatures.
2. Temperature drop. The temperature drop (outer) of the new product from the ring heating furnace to the rolling mill process line should generally ensure that the metallographic structure before the end of deformation is in the single phase zone.
3. Heating defects. The slab should be prevented from overheating or even overheating.
