Gas heat treatment chain furnaceIt is a forging heating device using gas as fuel.，the advantage is Efficient combustion and waste heat recovery system can significantly reduce energy consumption, thus reducing operating costs.、It has the advantages of high heating efficiency, high energy utilization, accurate temperature control, good environmental protection performance, simple operation and strong adaptability.、Adopting advanced combustion technology and materials, it has a long service life and low maintenance cost.、The user interface is friendly, and the operator is easy to use. At the same time, the equipment also has the function of fault diagnosis and alarm, which can find and deal with abnormal situations in time.、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.，the product looks atmospheric.，is an advanced Gas heat treatment chain furnace developed by our company in combination with the actual situation of the industry。

2、Gas heat treatment chain furnace structure

The Gas heat treatment chain furnace has the following structure

1. Radiation chamber

The heat load of the main place for Gas heat treatment chain 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. furnace chamber

A space for holding metallic materials for heating.

3. 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.

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.

3、Gas heat treatment chain furnace function

Gas heat treatment chain furnaceit has the functions of hardening and tempering, heat treatment, Forging heating, Casting heating and normalizing，at work,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 product looks beautiful.，Mainly used forMetal tempering,Energy conservation and environmental protection,Metal heat treatment,Metal melting and casting andImprove production efficiency，it can be used in metallurgy, chemical industry, Household necessities, shipping, petroleum and other industries。
