Mathematical simulation of flow field of molten steel in ladle furnace with argon blowing;

The Finite Element Analysis and Research of Ladle Furnace Buggy s Structure;

High-performance Q345B plate with a thickness ranging from 8 to 40mm has been successfully produced in a mass-scale with the newly commissioned 120 ton BOF at SISG, via the BOF-ladle furnace(LF)-continuous casting(CC)-2500 mill process route.

Revamp on high pressure vaccuum car system in LF furnace;

Variety steel smelting practice and refining effect analysis in LF furnace process;

The structure and function of LF furnace are introduced,The suitable steel grades and cost for LF refining furnace are emphasized in this paper.

Application of electrode regulator for LF and maintenance of associated equipment;

Probe to the Fast Desulphurizing Process on LF;

Practice on decreasing electric and electrode consumption of No.3 LF in Steel-making Plant;

Through ameliorating the technics of slag making,controlling process temperature , optimizing the technics of argon blowing,controlling deoxidizing ambience of refining process, modulating and estimation of slag capability,the rate of desulfurizing of ladle furnace was im- proved ,and the cost of production was reduced.

The constitution of the expert system in BF4~# of Xianggang,its configuration of software & hardware,the function and application in the furnace temperature prediction control and the furnace shape operation managemeat are introduced in this article.
