CIE Wins China Patent Excellence Award Again!

2023/07/25

On July 23, good news came from the State Intellectual Property Office that CIE's patent titled "A Smoke Circulating Pre-reduction Sintering Process" has been awarded the 24th China Patent Excellence Award. This significant accomplishment further adds to the company's list of accolades, which includes one gold award, one silver award, and five excellence awards.

 

 

A high-quality burden design is provided in the process for improving the quality and productivity of blast furnaces, as well as reducing energy consumption, thus effectively addressing problems caused by long reduction time, poor permeability of the burden layer, and low production efficiency in ironmaking processes. The sinter produced with this process features well-developed porosity, low total oxygen content, and excellent metallurgical performance. Based on this achievement, 59 patents have been laid out, including 35 invention patents. By implementing this patent, the sintering flue gas emission can be reduced by more than 20%, the energy consumption per ton of the sintering process can be reduced by 2kg standard coal, and the reduction of iron oxides can be completed by more than 35%. All those improvements can help to reduce the blast furnace load, lower the blast furnace fuel ratio, reduce coke consumption, and cut CO2 emission by more than 10%, bringing remarkable socio-economic benefits.

 

The China Patent Award is the highest accolade in the field of patents in China, featuring high credibility, representativeness, and influence. Since its establishment in 1989, 24 sessions of patent award evaluations have been successfully held, selecting a series of patent projects that demonstrate high innovation quality, good application benefits, and strong demonstrative effects. It vividly showcases the quality-oriented development, pursuit of quality, and quality achievements in China's intellectual property field.
