前言钢液真空循环脱气法(又称 RH 法)是1959年试制成功的,由于这种力法具有能适应氧气转炉的高生产率,能处理的钢种多,脱气效果好等一系列优点,因此,RH 设备的投产台数逐年增长。据不完全统计,目前世界上投产的RH 设备已有五十多台。其处理容量最小的为30吨,最大的为350吨。我国投产的台数已有五、六台,按台数仅次于日本和美国,居世界第三位。1968年以前 RH 设备主要用于配合平炉和电炉生产,降低钢液中的氢和非金属夹杂物的含量。而今天的 RH 设备已主要用于配合高生 Preface The molten steel vacuum cycle degassing method (also known as RH method) is a successful trial in 1959, due to the force method has to adapt to the high productivity of oxygen converter can handle a variety of steel, degassing effect and a series of advantages Therefore, the number of RH equipment put into operation has increased year by year. According to incomplete statistics, more than 50 RH units have been put into operation in the world at present. The processing capacity of the smallest 30 tons, the largest of 350 tons. China has put into operation the number of Taiwan has five or six, according to the number of units second only to Japan and the United States, ranking third in the world. Before 1968, RH equipment was mainly used for the production of open hearths and electric furnaces to reduce the content of hydrogen and non-metallic inclusions in molten steel. Today’s RH equipment has been used mainly for students
