Introduction to Hot rolling roller heat treatment furnace, advantages, characteristics and principles of heating furnace

Hot rolling roller heat treatment furnaceIt is a kind of equipment which uses gas as fuel and is specially used for heating metal before forging.，at work,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.，it is widely used inHousehold necessities,electron,chemical industry,metallurgy,aerospace and other industries，super quality and competitive price。The following is to introduce the Hot rolling roller heat treatment furnace:

1、Brief introduction of Hot rolling roller heat treatment furnace

Hot rolling roller heat treatment 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.，features include energy saving and environmental protection, Easy to maintain, Easy to control, energy-efficient and Easy to maintain，multifunctional, with functions such as anneal, Forging heating, hardening and tempering, normalizing and Casting heating。

2、Structural advantages of Hot rolling roller heat treatment furnace

The Hot rolling roller heat treatment furnace has the following structure

1. ventilation system

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

2. combustor

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

3. Radiation chamber

The heat load of the main place for Hot rolling roller heat treatment 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.

4. ventilation system

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

5. Waste heat recovery system

Used to recover the exhaust heat of the heating furnace. There are two kinds of recovery methods, one is to recover by preheating combustion air, so that the recovered heat can return to the furnace again; The other is to use another recovery system to recover heat. The former is called air preheating mode, and the latter is usually called waste heat boiler mode.

5、Hot rolling roller heat treatment furnace structure composition

The Hot rolling roller heat treatment furnace structure is introduced as follows:

1. 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.

2. combustor

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

3. furnace chamber

A space for holding metallic materials for heating.

4. Radiation chamber

The heat load of the main place for Hot rolling roller heat treatment 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. furnace chamber
