Introduction to Preheating trolley furnace and Forging furnace advantages and features

Preheating trolley furnaceIt is an efficient, energy-saving and environment-friendly metal heating device.，it is widely used in pharmacy, automobile, light industry, aerospace and heat treatment。

1、Brief introduction of Preheating trolley furnace

Preheating trolley furnaceIt is a kind of equipment which uses gas as fuel and is specially used for heating metal before forging.，Widely used inMetal heat treatment,Energy conservation and environmental protection,Improve production efficiency,Metal forging heating,Metal tempering and so on，multifunctional, with functions such as anneal, temper, quench, heat treatment and Forging heating。

2、Structural advantages of Preheating trolley furnace

The Preheating trolley furnace has the following structure

1. Radiation chamber

The heat load of the main place for Preheating trolley 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. 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 Preheating trolley 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. 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. 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.

3、Advantages of Preheating trolley furnace principle

Preheating trolley furnaceat the start of the operation,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.，multifunctional, with functions such as hardening and tempering, Casting heating, normalizing, anneal and hardening and tempering，it is mainly composed of ventilation system, furnace chamber, Radiation chamber, ventilation system and recovery of waste heat，productThe overall structural design is relatively simple and compact.，has been favored by more and more customers.。

4、Preheating trolley furnace function

Preheating trolley furnaceit has the functions of Forging heating, Casting heating, heat treatment, normalizing and temper，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.，Uniform heating and precise control can be realized, so it is helpful to improve the product quality and yield of metal materials.、Suitable for forging and heating of various metal materials, including steel, aluminum and copper. At the same time, it can also be used in metal heat treatment, tempering and other technological processes.、The use of clean and environmentally friendly natural gas as fuel effectively avoids the adverse effects of chemical reactions between impurities such as coal-fired furnaces and forgings during heating. At the same time, natural gas has high calorific value and high combustion temperature, and the combustion temperature can be further increased by preheating air and fuel. In addition, the gas forging heating furnace also has good heat loss control ability and intelligent control system, which can accurately adjust the ratio of air to natural gas, ensure full combustion of natural gas, and reduce mechanical incomplete combustion and chemical incomplete combustion.、Suitable for forging and heating of various metal materials, including steel, aluminum and copper. At the same time, it can also be used in metal heat treatment, tempering and other technological processes.、Efficient combustion and waste heat recovery system can significantly reduce energy consumption, thus reducing operating costs.，the product looks atmospheric.，it has the characteristics of Strong adaptability, energy saving and environmental protection, Stable and reliable, Easy to maintain and Easy to control。
