In order to realize a new iron/steel interface mode which uses the same ladle from BF to BOF,the ladle needs to possess multifunction such as hot metal container,transportation,cushion function and desulphurization,etc.

The interface reaction between the ammoniacal nitrogen and iron and steel melt is simulated.

Examining into the development and the application of the software and its analysis method for spectrograph, it has become history that ultra - low carbon was detected only by infrared carbon and sulphur analyzer in the past, and this presents an advantage to improving the analysis speed and the quality of smelt armco-iron.

Based on e-p analysis,the importance of structure adjustment for energy intensity reduction of Chinese steel industry is explained,and it is pointed out,that high iron/steel ratio is the major reason for high energy consumption,There are two primary factors influencing iron/steel ratio,i.

With the theory of the multi-dimensional mass flow controlling, we had investigated and researched ironmaking/steelmaking interface of all kinds of metallurgical enterprise at home and abroad during different times.
