Suzhou Guli Environmental Protection Technology Co., LTD. (hereinafter referred to as "Guli Environmental Protection") is located in Zhangjiagang City, Jiangsu Province, founded in September 2019, formerly known as Rizhao Kunou Environmental Protection Technology Co., LTD., established in 2016, mainly engaged in the process research and development and project operation of comprehensive utilization of solid waste resources such as dust dust in steel enterprises.

The company was established more than 4 years ago, gathered a group of professionals engaged in metallurgy, mechanical and electrical, chemical, design and other fields. The company has 45 employees, including 1 senior title, 7 intermediate and above titles, R & D personnel accounted for more than 20%. Through a large number of experimental research and scientific and technological research, the company has developed a mature set of comprehensive utilization technology of steel dust dust resources, the company has 2 authorized invention patents, in the state of substantive examination of 3 invention patents, utility model patents 4, software copyright 12, to achieve nearly 30 scientific and technological achievements.

In 2019, on the basis of a single production line for the treatment of sintered electric dust removal, the company developed the combined treatment technology of BF bag ash and sintered electric dust removal ash through technological upgrading and transformation, and successfully applied it to the comprehensive utilization of bulk solid waste resources in Zhangjiagang metallurgical dust mud resource treatment project constructed by Yonggang Group Co., LTD., which has been running stably for 4 years. At the same time, relying on the dechlorination brine washing process, it can not only reduce the situation of sintering grate and blast furnace notting caused by long-term cyclic enrichment of alkali metals in iron and steel enterprises, extend the service life of blast furnaces and sintering machines, but also reduce the carbon consumption and energy consumption of steel, relax the procurement standards of iron concentrate, and save raw material procurement costs. Help iron and steel enterprises to form a long-term mechanism to reduce costs and increase efficiency.

In the future, the company will further increase scientific and technological research and development efforts, improve the comprehensive utilization technology of steel dust and ash, realize the comprehensive utilization of iron and steel metallurgical dust and mud resources more efficiently, empower the green and scientific development of the steel industry, and jointly promote the high-quality development of the steel industry!
