How to choose a billet induction heating furnace?
The traditional steel rolling process is that the steel billets are stacked and cooled, transported to the rolling mill, and then heated in a heating furnace to be rolled into steel. This process has two defects. One is that after the billet is drawn from the steelmaking continuous caster, the temperature on the cooling bed is 700-900°C, and the latent heat of the billet is not effectively utilized. Second, after the billet is heated by the heating furnace, the surface of the billet loses about 1.5% due to oxidation. The energy-saving and emission-reduction technological transformation project of the rolling workshop implements continuous casting and rolling in response to the above-mentioned problems, but the second defect of heating with a regenerative heating furnace still exists. In order to fully save energy, it is more appropriate to use a billet induction heating furnace to perform on-line temperature raising and uniform heating of the continuous casting billet.
