Introduction to Trolley type preheating furnace and forging furnace structure principle

Trolley type preheating 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.，is a Trolley type preheating furnace。The following is to introduce the Trolley type preheating furnace:

1、Brief introduction of Trolley type preheating furnace

Trolley type preheating furnaceIt is a kind of heating equipment using natural gas as fuel, which is mainly used to heat metal materials to the required forging temperature in a short time.，is carefully developed by One-combustion energy saving combined with advanced technology。

3、Trolley type preheating furnace characteristics

The Trolley type preheating furnace features are as follows:

1. Efficient heating

The Trolley type preheating furnace can heat the metal material to the required temperature in a short time and improve the production efficiency.

2. Stable and reliable

The Trolley type preheating furnace has a stable combustion system and temperature control system, which can ensure the uniformity and stability of the temperature in the furnace, thus improving the quality and production efficiency of forged products.

3. Efficient heating

The Trolley type preheating furnace can heat the metal material to the required temperature in a short time and improve the production efficiency.

4. Easy to control

By adjusting the burner and ventilation system, the temperature and atmosphere in the furnace can be accurately controlled to meet the heating requirements of different metal materials.

5. energy saving and environmental protection

As a clean energy source, natural gas produces less pollutants after combustion, which is beneficial to environmental protection. At the same time, the application of waste heat recovery system further improves the energy utilization efficiency.

4、Working principle of Trolley type preheating furnace

Trolley type preheating furnacethe principle is simple.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 has a wide range of uses, and is often used inMetal forging heating,Energy conservation and environmental protection,Metal heat treatment,Metal melting and casting,Metal forging heating and so on。

5、Structural characteristics of Trolley type preheating furnace

The Trolley type preheating 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. ventilation system

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

3. Radiation chamber

The heat load of the main place for Trolley type preheating 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. furnace chamber

A space for holding metallic materials for heating.

5. combustor

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