Industrial burners have extensive and important applications in the metallurgical industry, as follows

In the steelmaking process, industrial burners are used to heat blast furnaces. The high-temperature flame generated by the burner can cause iron ore to react with reducing agents such as coke at high temperatures and be reduced to molten iron. Precise control of the temperature and combustion intensity of the burner can ensure the efficient progress of chemical reactions in the blast furnace and improve the output and quality of molten iron.

For different qualities of iron ore and production requirements, the parameters of the burner can be adjusted to adapt to different smelting conditions. For example, for high-grade iron ore, the combustion temperature can be appropriately reduced to save energy; while for low-grade iron ore, a higher combustion temperature is needed to ensure full reduction.

In the smelting process of non-ferrous metals such as copper, aluminum, and zinc, industrial burners also play a crucial role. The high temperature generated by the burner can melt metal ores or scraps into liquid metals, providing raw materials for subsequent refining and casting.

Different non-ferrous metals have different melting points and smelting characteristics, and industrial burners need to be customized according to the requirements of specific metals. For example, aluminum has a relatively low melting point, and the temperature of the burner can be appropriately reduced to avoid excessive heating; while copper has a higher melting point and requires a higher combustion temperature to achieve smelting.

Normalizing and annealing are common heat treatment processes in the metallurgical industry and are used to improve the microstructure and properties of metal materials. Industrial burners provide a stable high-temperature environment, allowing metal materials to be heated and held at a specific temperature, and then normalizing or annealing treatment is achieved by controlling the cooling rate.

The temperature control accuracy of the burner is crucial for the heat treatment effect. Precise temperature control can ensure that metal materials obtain the required microstructure and properties, and improve the hardness, toughness, and ductility of the material.

Quenching and tempering are important heat treatment processes for improving the hardness and strength of metal materials. Industrial burners quickly heat up to the quenching temperature, allowing metal materials to reach the required temperature in a very short time, and then quenching treatment is performed. Subsequently, tempering is carried out through the burner to reduce the hardness of the material and improve toughness.

The heating rate and temperature stability of the burner during quenching and tempering directly affect the properties of the material. Rapid heating can make the material obtain a fine grain structure and improve hardness and strength; while a stable tempering temperature can ensure that the material maintains a certain strength and toughness while reducing hardness.

In metallurgical production, many raw materials such as iron ore, coke, and limestone contain a certain amount of moisture. Before entering blast furnaces or other smelting equipment, these raw materials need to be dried to improve combustion efficiency and reduce energy consumption. Industrial burners provide high-temperature hot air for rapid drying of raw materials.

The hot air temperature and air volume of the burner can be adjusted according to the characteristics of raw materials and drying requirements. For raw materials with high moisture content, the hot air temperature and air volume can be increased to speed up the drying process; for volatile raw materials, the hot air temperature needs to be controlled to avoid the loss of raw materials and environmental pollution.

In metallurgical production, some equipment such as blast furnaces, converters, and electric furnaces need to be preheated before startup to prevent the equipment from being damaged by thermal stress when started in a cold state. Industrial burners provide preheating heat sources for these equipment to ensure that the equipment starts and operates within a safe temperature range.

The preheating temperature and time of the equipment need to be reasonably controlled according to the type, size, and material characteristics of the equipment. The temperature adjustment and stability of the burner are crucial for the preheating effect of the equipment. If the preheating temperature is uneven or unstable, it may cause local overheating or underheating of the equipment, affecting the service life and safety of the equipment.
