Alloy rod and wire heating furnace is widely used in steel and non-ferrous metal production, which affects production efficiency and product quality. The nitrogen oxides produced in the heating process of the heating furnace need to be denitrated. SCR technology is a common method to meet the requirements of environmental protection and protect the environment and human health.

Alloy rod and wire heating furnace has an important application in iron and steel manufacturing. It is mainly located between continuous casting process and hot rolling process and plays a role of buffer regulation. The heating furnace not only has an important impact on the production rhythm, but also a link with high energy consumption, and the effect of energy saving and consumption reduction is particularly important in this link. In addition, the configuration of the heating furnace and the production organization have a direct impact on the efficiency and product quality of the entire production line.

For the production process of high-strength aluminum alloy rod and wire, the heating furnace also plays an important role. For example, in the extrusion and drawing process, the aluminum alloy raw material needs to be heated by the heating furnace to reach the temperature suitable for processing. In addition, some advanced heating technologies, such as induction heating furnaces, because of their stable performance and fast heating speed, can improve the quality of special alloys and reduce the oxide layer, which is particularly important for the production of alloy rods and wires. However, during the production process of alloy rod and wire heating furnaces, nitrogen oxides (NOx) will be produced, which are atmospheric pollutants that are harmful to the environment and human health, can form acid rain, and cause damage to buildings, crops, and ecosystems. In order to meet increasingly stringent environmental standards, denitrification technology is needed to reduce NOx emissions.

In the process of steel production, the denitrification technology mainly includes selective catalytic reduction SCR and non-selective catalytic reduction methods, among which SCR technology is widely used at present. Under a certain temperature and catalysis, ammonia (NH₃) or urea is used as a reducing agent to reduce NOx to nitrogen N₂ and water (H₂O), which is a highly efficient and widely used denitrification technology. The alloy rod and wire heating furnace reduces nitrogen oxide emissions through denitrification treatment in the production process to meet the environmental requirements and protect the environment and human health. SCR denitration technology is a feasible solution, which has been applied in related projects and achieved good results.

In summary, alloy rod and wire heating furnace is widely used in the production of steel and non-ferrous metal materials, which is not only related to the production efficiency, but also directly affects the final quality of the product. With the development of industrial technology, the design and configuration of heating furnaces are constantly optimized to adapt to different materials and production needs. The heating process requires the use of denitrification technology, mainly in order to reduce NOx emissions, to meet environmental requirements, protect the environment and human health.
