Explanation

Utilize airflow transportation methods. The powder used for smelting is directly blown into the white part of the metal bath or the metallurgical reaction zone through the spray gun. To achieve a certain metallurgical process. Its main characteristics are: ① the powder injected has a large specific surface, which greatly accelerates the reaction rate between the white component of the melt and the powder; ② The conveying airflow strongly agitates the molten pool. Ensure that the molten pool and reaction materials sprayed with powder or reaction zone white can be uniformly mixed in a short period of time; ③ The interaction between the injected powder and metal melt components or reaction materials occurs in the white part or reaction zone of the melt, which reduces the influence of furnace lining, slag and atmosphere on the reaction process. injection metallurgy technology is widely used in various fields of metallurgy. Such as blast furnace coal injection, hot metal pretreatment, ladle metallurgy, smelting reduction and other processes in iron and steel metallurgy.
