CISDI Electric Co’s revolutionary metallurgical industrial motor system has won accolades for its energy-conserving capabilities.

In 2022 the system was included in The Directory of Energy Conservation Tech and Equipment Recommendations by China’s Ministry of Industry and Information Technology.

It won this national and sectoral recognition for its energy-saving and carbon-reducing achievements.

A number of the system’s products have increased energy conservation credentials. They include:

The world-class metallurgical industrial HV frequency control equipment, which was ranked in The Directory of Industrial Power Demand Side Recommendations by China’s Ministry of Industry and Information Technology (3^rd Batch) and MCC’s Top 10 Core Tech Typed Products

² Energy-conserving motors, driven unit and drive system

² Energy-saving pipeline network system

² Optimised collaborative components or sub-systems

² Energy-efficient system control units

² The process control model for hot rolling’s scale breaking and BOF dust collection by integrating the domain knowledge and the digital tech.

The system achieves remarkable reductions in carbon emissions when applied to high-pressure scale breaking and BOF primary dust collection systems. It also achieves:

ü An increase in overall power saving rate of 5 to 10 per cent

ü A 15 per cent reduction in the system’s fault rate

ü A 15 per cent productivity enhancement.

Case study:

A (1,700mm) hot rolling line’s high-pressure scale breaking system originally applied five water pumps, each with a power output of 710-kilowatts.

Water delivery pressure was regulated by operating a variable number of pumps.

The outdated production method caused discontinuous pressure control, heavy pump wear and high maintenance costs.

The line was modified by applying CISDI Electric’s scale breaking system solutions, which replaced the original five pumps with one water pump with an output power of 4,500 kilowatts.

The new system takes eight seconds to accelerate from 15 to 50 hertz and needs 20 seconds to decelerate to 15 hertz.

The outstanding speed regulation performance reduces the system’s vibration, extends the water pump’s service life and enhances the automation level.

This advanced solution has resulted in annual maintenance and power savings totalling hundreds of thousands of US dollars.

CISDI Electric’s MVC1200-06k/195 HV frequency converter is applied for a casthouse’s dedusting fan at a blast furnace ironmaking plant. It resulted in a 10.5 per cent power saving and an annual power consumption reduction of 1.26x10⁶ kilowatt per hour, equivalent to savings of around US$ 90,000.
