序言从1900年以后,贝氏转炉钢的产量日趋下降,这主要是钢的质量问题,钢的质量问题与钢的含氮量和含磷量的过多是分不开的。磷的问题由于采用了碱性吹炼法得到解决;而氮的问题一直是多年来研究试验工作者的奋斗目标。关于降低氮的含量方面有下列两种可能性:(1)在吹入空气中采用富氧或其他气体以达到降低钢的含氮量。(2)纯氧顶吹法。1856年,亨利·贝氏麦(Henry Bessemer)就曾经倡仪过用氧气来代替空气在转炉内进行炼钢,在1876
Preface From 1900 onwards, Belden converter steel production declining, which is mainly the quality of steel, the quality of steel and steel nitrogen content and phosphorus content are inseparable. Phosphorus problems have been solved by the alkaline blowing method; and the problem of nitrogen has been the goal of research experimenters for many years. There are two possibilities for reducing the nitrogen content: (1) Oxygen-enriched or other gas is used in the blown air to reduce the nitrogen content of the steel. (2) pure oxygen top-blowing method. In 1856, Henry Bessemer had advocated the use of oxygen instead of air to make steel in converters. In 1876,
