Taking steel as an example, in forging and rolling production, the steel billet is generally heated in an oxidizing atmosphere of a complete combustion flame, and an incomplete combustion reducing flame is used to directly heat the metal to achieve the purpose of no oxidation or less oxidation. During heating, the billet moves continuously in the furnace according to the rhythm of forging and rolling, and the furnace gas also flows continuously in the furnace. During the whole process, the heating furnace needs to strictly control the temperature change, otherwise the uneven furnace temperature will lead to uneven annealing of the steel plate.
