What is a Trolley mold preheating furnace? Introduction to the Working Principle of heating furnace

Trolley mold preheating furnaceIt is a kind of equipment which uses gas as fuel and is specially used for heating metal before forging.，Heat of combustion based on fuel. Natural gas is sprayed from the burner, mixed with combustion-supporting air and burned to produce high-temperature flame and smoke. These high-temperature flames and smoke transfer heat to the metal materials in the furnace by radiation and convection, so that they gradually heat up to the temperature required for forging.。The following is to introduce the Trolley mold preheating furnace:

1、Brief introduction of Trolley mold preheating furnace

Trolley mold preheating furnaceIt is an efficient, energy-saving and environment-friendly metal heating device.，Widely used in Metal forging heating, Energy conservation and environmental protection, Metal forging heating, Improve production efficiency and Metal melting and casting，it has the functions of Forging heating, heat treatment, quench, hardening and tempering and heat treatment，is a common Trolley mold preheating furnace，is developed and improved by One-combustion energy saving。

2、Trolley mold preheating furnace application

Trolley mold preheating furnaces have the following purposes.

1. Improve production efficiency

The Trolley mold preheating furnace has the advantages of fast heating speed and accurate temperature control, which can improve production efficiency. This is especially important for mass-produced forging workshops.

2. Metal tempering

By properly heating and cooling the metal material, the Trolley mold preheating furnace can realize the quenching and tempering treatment of the metal. This is helpful to adjust the hardness and toughness of metal to meet the needs of different workpieces.

3. Energy conservation and environmental protection

The Trolley mold preheating furnace uses clean energy as fuel, which has lower emissions and higher energy efficiency than traditional coal-fired or oil-fired stoves. This is helpful to reduce environmental pollution and realize green production.

4. Metal melting and casting

Although it is mainly used for forging heating, some types of Trolley mold preheating furnaces can also be used in metal melting and casting processes. This is especially suitable for melting and casting of small or special alloys.

5. Metal melting and casting

3、Structural characteristics of Trolley mold preheating furnace

The Trolley mold preheating furnace has the following structure

1. Radiation chamber

The heat load of the main place for Trolley mold 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.

2. ventilation system

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

3. furnace chamber

A space for holding metallic materials for heating.

4. convection chamber

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

5. 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.

5、Advantages of Trolley mold preheating furnace principle

Trolley mold preheating furnacein the course of 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.，widely used in pharmacy, aerospace, heat treatment, chemical industry, shipping and other fields。
