摘要
合成渣包裹铝丝脱氧是钢水脱氧工艺的一种新的尝试。它吸收了最新脱氧技术和炉外精炼技术的长处,具有较优越的脱氧性能。实验研究表明:在相同条件下,使用包裹铝丝的终氧含量比无包裹铝丝脱氧低40～300ppm,夹杂个数和平均粒径分别减少226个和1.9μm。脱硫率同时可达50％。
Calcium aluminate-based fluxes are widly used nowadays in refining of steels because molten calcium aluminate enhances the extent of deoxi-dization of liquid steel and has a high sulphide capacity. By means of this fact, a new deoxidant of steel in which aluminium wire is wraped with high CaO content flux (AWF) is used in this study. Compared with the deoxidizing results of aluminium alone in liquid steel, it is concluded that the final oxygen content is lowered 40-300 ppm, the number and size of inclusions decrease by 226 and 1.9UUUUUUUUUUm respectively. At the same time, the desulphurization ratio reaches 50%.
