Introduction to Progressive heating furnace, forging furnace advantages, characteristics and principles

Progressive heating furnaceIt is an efficient, energy-saving and environment-friendly metal heating device.，It has the functions of Metal tempering, Improve production efficiency, Metal forging heating, Energy conservation and environmental protection and Metal heat treatment，the product looks atmospheric.，at runtime,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 is usually composed of furnace chamber, Radiation chamber, ventilation system, ventilation system and combustor，This productThe overall structural design is simple and novel.。The following is to introduce the Progressive heating furnace:

2、Structural advantages of Progressive heating furnace

The Progressive heating furnace has the following structure

1. Radiation chamber

The heat load of the main place for Progressive heating furnace heat exchange accounts for about 70%-80% of the whole furnace. The furnace tube in the radiation room conducts heat through flame or high-temperature flue gas, which is mainly radiant heat, so it is called radiation tube.

2. convection chamber

The material is heated by convection heat transfer of high temperature flue gas discharged from the radiation chamber. Flue gas washes the tube wall of the furnace tube at a high speed to carry out effective convection heat transfer, and its heat load accounts for about 20%-30% of the whole furnace. The convection chamber is generally arranged above the radiation chamber, and some are placed on the ground alone. In order to improve the heat transfer effect, nail head tubes or finned tubes are often used in furnace tubes.

3. furnace chamber

A space for holding metallic materials for heating.

4. Radiation chamber

The heat load of the main place for Progressive heating furnace heat exchange accounts for about 70%-80% of the whole furnace. The furnace tube in the radiation room conducts heat through flame or high-temperature flue gas, which is mainly radiant heat, so it is called radiation tube.

5. combustor

The device that mixes natural gas with combustion-supporting air and ejects it is the core component of the heating furnace.
