Slab heating furnace

The working principle of slab heating furnace mainly relies on the full combustion of fuel in the furnace, thereby generating high-temperature flames and flue gas. These high-temperature heat sources are then used to heat the constantly flowing medium in the furnace tube, ensuring that it can meet specific process temperature requirements. The specific process is as follows:
Combustion process: Fuel is sprayed and burned in the burner, generating high-temperature flames and smoke. These high-temperature flames transfer heat to the furnace tubes inside the radiation chamber through radiation, and further conduct it to the medium flowing inside the furnace tubes

Smoke convection: High temperature smoke enters the convection chamber of the heating furnace upwards under the suction force of the chimney or the action of the induced draft fan. Here, the flue gas transfers heat to the furnace tube inside the convection chamber through convection, and also conducts it to the medium inside the furnace tube
Classification and structural characteristics of slab heating furnaces
The slab heating furnace can be divided into various types, commonly including step heating furnace and induction heating equipment.
Step by step heating furnace: This type of heating furnace relies on a series of actions such as the rise, advance, fall, and retreat of the furnace bottom or water-cooled metal beam to move the billet step by step forward. The walking beam heating furnace has advantages such as flexible material transportation, high output per unit furnace bottom area, good heating quality, small footprint, and energy saving
Induction heating equipment: a device that combines a controllable silicon frequency converter with an induction heating coil to heat materials or workpieces to the forging temperature through frequency conversion current

Application scenarios and importance of slab heating furnace
The slab heating furnace is widely used in steel production, especially playing a crucial role in the rolling process. By heating at high temperatures, the plasticity of the steel billet can be improved, the deformation resistance can be reduced, making it easier to deform, thereby increasing the productivity and operating rate of the rolling mill. In addition, heating can improve the internal structure and properties of steel billets, ensuring that the rolled products have excellent geometric dimensions and mechanical properties
