Core Technologies and Products

CISDI has achieved multiple major breakthroughs on steel engineering, research and development, and applications. 

 

Environmental protection, intelligent, and high-efficiency stockyard

More than 40 domestic and overseas projects have applied CISDI's green, energy conservation and intelligent stockyard technologies, leading in performances of unmanned or less labored operation, consumption reduction, land and cost saving, and operation efficiency enhancement.

It is a critical promotional technology by the national environmental technology authority

    

High-efficiency, low-consumption mega blast furnace

More than 20 domestic and overseas mega blast furnaces in a volume level of 4,000 cubic meters have applied CISDI's high-efficiency, low-consumption and intelligent blast furnace's design, equipment and control. They are or will be performing with world-class indicators.

It has been awarded an excellent Chinese patent. 

 

 

 

Blast furnace's no-bell top

CISDI-developed no-bell top has been widely used for the large blast furnaces in Baosteel Zhanjiang, POSCO Indonesia and Formosa Ha Tinh Steel Vietnam plants. Their performances are leading the world. 

 

 

 

 

 

CISDI-SACS (self-adaptive constraint system) 4-point linkage suspension system

The world's initial four-point linkage suspension system for basic-oxygen furnace (BOF) is a patented technology of CISDI, seeing more than 10 BOFs' applications. 

 

 

 

Green EAF 

CISDI's green EAF is a great contributor to energy-conservative and environment-friendly steelmaking sector and reduces electric consumption by (60~100)kWh per tonne of liquid steel, compared with the conventional electric furnace. 

 

 

 

 

Continuous caster

CISDI has made major breakthroughs in high-speed continuous casting of ultra-thick slab, bloom and shaped blank, flat blank, and billet.

Leading China's continuous casting sector, CISDI focuses on product mix upgrade, model optimisation, strand quality diagnosis and optimisation, casting equipment diagnosis and rebuild, casting process parameter calculation and simulation.

The billet casting speed in CISDI's design and references has stabilised at 3.75 meters per minute, and peaked at 4.08 meters per minute. 

 

 


ZLD

CISDI blazes a trail in realising ZLD (zero liquid discharge) in a metallurgical plant. Being an expert in advanced industrial waste water utilisation technologies, CISDI has achieved the target of less than 4 cubic meters of fresh water consumption per tonne of steel for solving the steelworks' water resources conservation and environmental protection.
