Double pass tempering furnaceat work,The high-temperature flame and flue gas generated when the fuel burns in the furnace are used as heat sources to heat the medium flowing in the tube to reach the specified process temperature. Fuel is ejected from the burner and burned, resulting in high-temperature flame and high-temperature flue gas. The high-temperature flame transfers heat to the furnace tube in the radiation chamber through radiation, and then to the medium in the furnace tube. The high-temperature flue gas enters the convection chamber of the heating furnace upward due to the suction force of the chimney or the action of the induced draft fan, and the heat is transferred to the furnace tube in the convection chamber by convection, and then to the medium in the furnace tube.，it has the functions of temper, Forging heating, normalizing, heat treatment and Casting heating，It has a wide range of uses, including Improve production efficiency, Metal melting and casting, Metal heat treatment, Metal tempering and Energy conservation and environmental protection。
