the heating temperature of tube blank of seamless tube manufacturer refers to the discharge temperature of tube blank. It should be determined to ensure that the steel undergoes acceptor deformation in the optimum plastic range. The basis for determining the heating temperature is the iron and carbon balance diagram. In practice, the following factors should usually be considered.


1. steel grade. Different kinds of steel correspond to their different heating temperatures.
2. Temperature drops. Temperature drop (exterior) of new products from ring heating furnace to rolling mill production line should usually ensure that the metallographic structure is in a single phase zone before the end of deformation.
3. Heating defects. Slab should be prevented from overheating or even overheating.
