Based on the temperature distribution, the furnace chamber is divided along its length into a preheating zone, a heating zone, and a soaking zone.
The preheating zone is located at the charging end, where the temperature is lower; its function is to utilize the heat from the furnace gases to improve the furnace's thermal efficiency.
The heating zone serves as the primary heating section; the furnace gas temperature here is higher to facilitate rapid heating.
The soaking zone is located at the discharge end; the difference between the furnace gas temperature and the metal temperature is minimal, ensuring uniform cross-sectional temperature of the discharged billets.
