Deoxidization effect research of a new Al based complex deoxidizer
As a deoxidizer for steelmaking,Al has a problem of oxidation loss when it is added into liquid steel,which leads to a lower utilization rate of Al. At the same time,the high melting point and irregular shape of the deoxidization products make it difficult to remove Al2O3 inclusions from molten steel effectively,which causes nuzzle clogging and steel quality deteriorative. A new kind of complex deoxidizer which takes Al as the effective deoxidization component and a low melting point slag including Al2O3-Si O2-Mg OCa O as the carrier was investigated to improve the deoxidization utilization rate of Al and make the deoxidization products eliminate quickly from molten steel. Experiment results showed that the complex deoxidizer not only guaranteed the dissolved oxygen content in molten steel below 10 × 10-6,but also made the deoxidization inclusions fewer and smaller. Compared with Al deoxidization,the purity of steel was significantly improved and an excellent deoxidization effect was presented.
期刊介绍：
Chinese Journal of Engineering Design is a reputable journal published by Zhejiang University Press Co., Ltd. It was founded in December, 1994 as the first internationally cooperative journal in the area of engineering design research. Administrated by the Ministry of Education of China, it is sponsored by both Zhejiang University and Chinese Society of Mechanical Engineering. Zhejiang University Press Co., Ltd. is fully responsible for its bimonthly domestic and oversea publication. Its page is in A4 size. This journal is devoted to reporting most up-to-date achievements of engineering design researches and therefore, to promote the communications of academic researches and their applications to industry. Achievments of great creativity and practicablity are extraordinarily desirable. Aiming at supplying designers, developers and researchers of diversified technical artifacts with valuable references, its content covers all aspects of design theory and methodology, as well as its enabling environment, for instance, creative design, concurrent design, conceptual design, intelligent design, web-based design, reverse engineering design, industrial design, design optimization, tribology, design by biological analogy, virtual reality in design, structural analysis and design, design knowledge representation, design knowledge management, design decision-making systems, etc.
