The basic oxygen steel-making process is another important technical revolution following the Bessemer process and the Thomas process. It is now playing a vital part in the steel industry in countries like West European countries, Japan, etc. After taking stock of the present steel production and modern development in several leading countries and after comparing various kinds of oxygen steel-making processes, the author points out that the basic oxygen steel-making process is the main trend in steel production from now on. In his thesis, the author compares by illustrations the basic oxygen process and the open-hearth process in the following respectsthe methods of operation, the suitability of raw materials, the total yield, production costs, and the investments in basic construction. He also points out with emphasis that the basic oxygen process surpasses the open-hearth process in the kinds of products and their quality. He takes into considerations of the resources and the conditions of production of our country, and gives his personal opinion at the end of his thesis: The question of making immediate use of oxygen is on the programme today. The rapid development of oxygen steel-making should become one of the significant measures to push forward the production of the whole industry.

碱性氧气轉炉炼鋼法是继貝士麦炼鋼法和托馬斯炼鋼法之后又一次重要的技术革命,已經在若干国家如西欧国家、日本等炼鋼工业中起着巨大的作用。作者从世界上几个主要产鋼国家现时生产和发展的形势,在比較了不同类型的氧气炼鋼方法后指出:碱性氧气轉炉冶炼是今后炼鋼的一个主要发展方向。文中作者用实例就碱性氧气轉炉的操作方法、原料的适应性、金属收得率、产品成本以及基建投资等方面与平炉作了对比,并着重指出:碱性氧气轉炉鋼在品种和质量方面与平炉鋼相比較,实有过之而无不及。作者結合我国资源和生产情况,在文末提出个人意見,认为:氧气在我国冶金工业中的加速使用已經提到日程上来。加速发展氧气炼鋼应成为进一步推动整个工业生产的重大措施之一。

A new process of metallurgy of rare metals zirconium and hafnium with caustic soda instead of sodium carbonate to rub up zircon is examined. Using this process not only the rate of recovery of zirconia may be enhanced and the zircon, sodium silicate and sodium sulphate in wastes may be recovered; but also the dry waste of sludge may be largely reduced; moreover, the radioactive liquid waste may be reduced within the permissible discharge limits. The flow sheet of product and the synthetical utilization of wastes...

This article reviews the new subject of Metallurgical Reaction Engineering (MRE), which is rapidly developing in the metallurpical field recently all over the world. A brief introduction of the foundamentals of MRE is made. Through the sintering of fine ore together with blast furnace smelting the general theories and analytical methods in the steady state are described. Two examples given show that mathematical simulations can be obtained by the application of MRE. The active development of the study of MRE at present will promote the theoretical research of metallurgy and the modernization of production technology in metallurgical industry.
