In 2002, in accordance with the relevant policies of the National Development and Reform Commission (NDRC) for promoting energy-saving and environmentally friendly coke dry quenching (CDQ) projects, the company actively collaborated with relevant design institutes to develop an explosion-proof secondary dust collector specifically for Coke Dry Quenching (CDQ) systems. This innovation combines advanced international CDQ technologies with tailored solutions to address the unique challenges of coke powder, including these key Features: high dust concentration; irregular particle size distribution (from fine powder to coarse granules);sharp-edged abrasive particles; explosive risks.This system was first successfully implemented at Wuhan Iron & Steel (WISCO) Coking Plant's inaugural Coke Dry Quenching (CDQ) project. It has now been operating continuously for nearly 20 years without any failures, demonstrating exceptional stability and performance on par with Japanese-made equivalents.In the meantime, since 2005, our company has successfully exported equipment to leading international steelmakers, including: Nippon Steel（Japan） , JFE Steel（Japan）;Tata Steel（India）, JSW Steel（India）, BSL Ltd（India）This demonstrates our proven design and manufacturing capabilities for export-grade products, with field performance receiving unanimous approval from all international clients. Our company's designed and manufactured Coke Dry Quenching (CDQ) Secondary Dust Collectors have been widely adopted across the coking industry, with particular dominance in:Top-Charge Coke Oven CDQ Systems and Stamp-Charged Coke Oven CDQ Systems.Till now,our equipment has been selected by over 300 domestic and international clients, with 480+ units successfully operating for years, achieving a market share exceeding 90%. Among them, representative ones include:Wisco Coking ;Ma Steel Coking ;Ansteel Coking ;Shagang Coking ;Tisco Coking ; Shougang Jingtang Coking ;Baosteel Coking; Nippon Steel Coking (Japan);JFE Steel Coking (Japan); Tata Steel Coking(India);Formosa Ha Tinh Coking (Vietnam).With years of proven operation in coke dry quenching (CDQ) process lines, we have delivered remarkable results, earning multiple national patents.
