1、Brief introduction of Continuous well type annealing furnace

Continuous well type annealing 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.，the main features are Easy to control, Stable and reliable, Easy to maintain, energy-efficient and energy saving and environmental protection，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.、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.、It can improve the plasticity and fluidity of metal materials, reduce the difficulty and cost of forging, and improve product quality and production efficiency.、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.、Adopting advanced combustion technology and materials, it has a long service life and low maintenance cost.，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 an ideal choice for customers to buy Continuous well type annealing furnace。

6、Continuous well type annealing furnace structure

The Continuous well type annealing 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. Radiation chamber

The heat load of the main place for Continuous well type annealing 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.

Continuous well type annealing furnaceat runtime,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.，It is a kind of equipment which uses gas as fuel and is specially used for heating metal before forging.，the product looks beautiful.。
