Determination of heating temperature of tube billet
- Feb 02, 2018 -

The heating temperature of the tube billet is the temperature of the tube billet to out of furnace. It should ensure that the steel in the best plastic deformation range of the implementation of the main deformation, to determine the heating temperature is the basis of Fe. carbon balance diagram, in practical operation, the general should consider the following factors. ① Steel grade. Different steel grades correspond to their different heating temperatures. ② Temperature drop. The temperature drop (outside) of the new product on the process line of the ring furnace to the rolling mill is generally guaranteed to be in the single-phase zone before the deformation is terminated. ③ Heating defects. The billet should be prevented from overheating or even burning.
