CISDI undertakes building of two 4,350 m³ BFs and their supportive design, supply, installation, construction, training, blow-in and ramp-up services on EPC mode, in the target of producing 6,394,500 tpy hot metal, which are the tasks in Step 1 of FHS Mill Phase I action plan.

 

The two blast furnaces will be implemented with CISDI-developed novel parallel bell-free top charging equipment, breaking the long-term technical monopoly by overseas competitors, and CISDI-developed environment-friendly energy-efficient drum for slag granulation, and sectional cascade water supply and drainage system for the furnace proper coolers, the transverse cooling staves for hearth, triplex ceramic burner for stove and fume self-circulation for PCI system.

 

On automation control, the FHS BFs project will employ the Ethernet-based fully-integrated EIC (electric-instrumentation-control) system, integrated intelligent MCC (motor control center), intelligent instrumentation, microcomputer protection and equipment monitor system. The whole smelting process of blast furnaces can be controlled in the central control building, which will offer the overall automation control solutions to smooth and safe running of blast furnaces. The process optimization means will be also used such as bell-free distribution model, stove combustion model and blast furnace expert system.

 

October 10, 2012 witnessed the signing ceremony of blast furnace and reheating furnace contracts between FHS and CISDI in Beijing. It was a milestone signifying the first export of Chinese 4,000 m³ blast furnaces. Presently, the No.1 and 2 BFs are under construction as scheduled, faster than other units of FHS Complex. The piling and foundation construction has been approved by FHS.
