Abstract

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.

一种新型铝基复合脱氧剂的脱氧效果研究

作为炼钢用的脱氧剂，Al在加入钢液时存在氧化损失的问题，导致Al的利用率较低。同时，脱氧产物熔点高，形状不规则，难以有效去除钢液中的Al2O3夹杂物，造成熔口堵塞，钢质变差。为了提高铝的脱氧利用率，使钢液中的脱氧产物迅速消除，研究了一种以铝为有效脱氧成分，以Al2O3-Si - o_2 - mg - OCa - O低熔点渣为载体的新型复合脱氧剂。实验结果表明，复合脱氧剂不仅保证了钢液中溶解氧含量低于10 × 10-6，而且使脱氧夹杂物更少、更小。与铝脱氧相比，钢的纯度明显提高，脱氧效果良好。

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.
