What is a Grey cast iron heating furnace? Introduction to the advantages, characteristics, and principles of the Forging furnace

Grey cast iron heating furnaceIt is a kind of equipment that uses natural gas as fuel to heat metal materials and make them reach forging temperature.。

1、Brief introduction of Grey cast iron heating furnace

Grey cast iron heating furnaceIt is an efficient, energy-saving and environment-friendly metal heating device.，Natural gas is mainly used as fuel, but some equipment also supports other types of gas or liquid fuel, which has strong fuel adaptability.、It has the advantages of high heating efficiency, high energy utilization, accurate temperature control, good environmental protection performance, simple operation and strong adaptability.、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.、Natural gas is used as a heat source, resulting in less waste gas and smoke after combustion, and less pollution to the environment. This will help reduce industrial emissions and improve the atmospheric environment.、Natural gas is mainly used as fuel, but some equipment also supports other types of gas or liquid fuel, which has strong fuel adaptability.。

2、Grey cast iron heating furnace structure

The Grey cast iron heating furnace structure is introduced as follows:

1. ventilation system

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

2. furnace chamber

A space for holding metallic materials for heating.

3. 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.

4. combustor

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

5. Radiation chamber

The heat load of the main place for Grey cast iron heating 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.
