随着BOF复合吹炼的发展和对低氮钢需求量的增加,Ar的用途增多了。作为降低英国钢铁公司气体成本的研究的一部分,由设在米德尔斯布勒的格兰吉塘的蒂兹赛德实验室与英国化学工业公司(ICI)设在比林厄姆的化合物与聚合物有限公司协作,研究了一些用CO_2来取代Ar的应用领域。作为复合吹炼的搅拌气体,如果要保持现行的吹Cr搅拌的高效率,那么采用CO_2还存在些问题。但是,在铸机滑动水口上的一些新用途,如同其在特殊钢种出钢时用于钢包气氛控制和将来用于钢包电弧炉的气氛控制一样,都将是很有前途的。
With the development of BOF compound blowing and the increasing demand for low nitrogen steel, the use of Ar has increased. As part of a study to reduce the gas costs of British steel companies, the Tidyards Laboratories at Grantown Pond in Middlesbrough and the British Chemical Industry Company (ICI) Co., Ltd. collaborated to study some of the applications of CO2 to replace Ar. As a compound blowing blowing gas, if you want to maintain the current high efficiency of blowing Cr stirring, then there are some problems with CO_2. However, some of the new uses at the skid nozzle of the caster would be as promising as the control of the ladle atmosphere at the time of tapping of the special steels and the future atmosphere control of the ladle electric arc furnace.
