Realizations on cooling ways of blast furnace;

Nonlinear mixed control for silicon contents of hot metal in BF ironmaking processes;

Integrated application of intelligent software packs,which was run on LAN in BF main control room,is proven to be of great value to parameter optimization of BF ironmaking process.

The application and generalization of BF Ironmaking Optimization and Expert System(IOES) show that the computer intelligent control technique obviously increases the economical effects of BF ironmaking.

This paper describes the current trend of ironmaking technology both at home and abroad and points out that the core of technological improvement is the competition between looking for a new ironmaking route capable of replacing blast furnace and further perfecting the existing blast furnace ironmaking technology.

Propose save and reasonable use coal by way of coal process before combustion raise thermal efficincy of generate electricity and develop non-blast-furnace iron making, realax difficulty and ensure safety of energy in China.
