What is a Large roller furnace? Introduction to the Working Principle of forging furnace

Large roller furnaceIt is an important heating equipment before metal forging. It uses natural gas as fuel to heat metal materials through high-temperature flame and smoke generated by combustion to meet the requirements of forging process.，the advantage is Using regenerative combustion system or advanced burner design can realize the uniform distribution of temperature in the furnace, ensure the uniform heating of metal materials and improve product quality.、Natural gas is mainly used as fuel, but some equipment also supports other types of gas or liquid fuel, which has strong fuel adaptability.、Efficient combustion and waste heat recovery system can significantly reduce energy consumption, thus reducing operating costs.、It has the advantages of high heating efficiency, high energy utilization, accurate temperature control, good environmental protection performance, simple operation and strong adaptability.、The metal material can be heated to the required temperature in a short time, and the production efficiency is improved.，multifunctional, with functions such as Forging heating, temper, anneal, Casting heating and Forging heating，is a common Large roller furnace，Mainly used forMetal melting and casting,Metal forging heating,Metal heat treatment,Energy conservation and environmental protection andImprove production efficiency。

1、Brief introduction of Large roller furnace

Large roller furnaceIt is a forging heating device using gas as fuel.，usually used in pharmacy, Machinery manufacturing, light industry, electron, machinery and other fields，the product looks atmospheric.，at runtime,Heat of combustion based on fuel. Fuel gas (such as natural gas, liquefied petroleum gas, etc.) is mixed with combustion-supporting air through the burner and burned to produce high-temperature flame and flue gas. These high-temperature flames and smoke exchange heat with metal materials in the furnace, so that they gradually heat up to the temperature required for forging.，is an advanced Large roller furnace developed by our company in combination with the actual situation of the industry。

4、Large roller furnace structure composition

The Large roller furnace has the following structure

1. Radiation chamber

The heat load of the main place for Large roller 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. ventilation system

Ensure the gas flow in the furnace and maintain the stability of the atmosphere and temperature in the furnace.

3. combustor

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

4. Radiation chamber

The heat load of the main place for Large roller 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. convection chamber

The high-temperature flue gas discharged from the radiation chamber is used for convective heat transfer to further heat the metal materials.

Large roller furnaceat the start of the operation,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.，widely used in heat treatment, chemical industry, petroleum, aerospace, war industry and other fields。
