七十年代炼钢工艺科学中的突出成就是在炼钢生产中广泛地应用炉外精炼技术,而喷射冶金则是炉外精炼的重要手段。这种技术目前应用于铁水预处理、钢水精炼和向炉内喷吹的强化冶炼,其冶金效果十分显著。 气力输送的工艺设计、首先要了解粉料的特性(品种、粒度配比、物理化学性能等)和输送条件(喷吹的粉量、总的送粉时间、最大送粉速度),然后进行工艺方案设计。 Outstanding achievements in the science and technology of steelmaking in the seventies are the extensive application of furnace refining technology in steelmaking, while the injection metallurgy is an important means of refining outside the furnace. This technique is currently used in hot metal pretreatment, molten steel and blast furnace to strengthen the smelting, the metallurgical effect is very significant. Pneumatic conveying process design, we must first understand the characteristics of the powder (variety, size ratio, physical and chemical properties, etc.) and delivery conditions (blowing the amount of powder, the total feeding time, the maximum feeding speed), and then the process Design.
