Current state and subjects of high purity steel refining technology

摘要

The refining process advanced by the development of the multi-step refining process with the hot metal refining and the secondary refining process technology and the upgrades of these technology in recent years. The technology to separate the slag from metal efficiently and prevention of pollution and promotion of slag metal and gas-metal reaction is essential in further advance of these process and promotion of environmental harmony establishing the byproduct and energy loss minimum. The exhaust control of the byproduct is an important problem. Needs for the new idea excavation by progressing of the component technology and a new aspect rise with the elucidation of the phenomenon staying up now because demands increases so far Moreover, needs for the sensing technology for the process control are also high.
