一、概述石灰基粉剂具有资源丰富、价格低廉、操作安全简便等优点,但由于存在易吸潮的致命弱点,限制了它在喷射冶金中的应用。东北工学院和黑龙江小岭铁合金厂经一年多的研究实践,研制出了CaO含量高、SiO_2含量低的抗潮石灰,在钢水脱硫脱磷及净化夹杂诸方面收到了与喷吹等量Ca-Si粉剂相近的效果,经济效益相当可观。为了探索这种粉剂对铁水脱硫的效果,推动铁水炉外脱硫技术的发展,在大量物性测定和冷喷实践
First, an overview of lime-based powder with rich resources, low prices, safe and easy operation and other advantages, but because of the existence of a fatal weakness of moisture absorption, limiting its application in the jet metallurgy. Northeast Institute of Technology and Heilongjiang Xiaoling ferroalloy plant more than a year of research and practice, developed a high CaO content, low SiO2 content of the anti-chalky lime in the molten steel desulphurization dephosphorization and purification inclusions have received the same amount of blowing Ca -Si powder similar results, the economic benefits are considerable. In order to explore the effect of this powder on hot metal desulphurization and to promote the development of desulphurization technology outside the hot metal ladle, a large number of physical properties and cold spray practice
