After the reorganization of Ansteel and Benxi Iron and Steel Group in 2021, Benxi Iron and Steel Group officially became a second-tier subsidiary controlled by Ansteel Group. Benxi Iron and Steel (Group) Equipment Engineering Co., Ltd. (hereinafter referred to as “Equipment Engineering” or “the Company”) is affiliated with Ansteel Group Benxi Iron and Steel Group Co., Ltd. and is a controlled subsidiary under Benxi Iron and Steel Group. The Company’s registered capital is RMB 100 million. It is the only diversified enterprise among Benxi Iron and Steel Group’s subsidiaries capable of providing comprehensive services covering infrastructure construction, equipment maintenance and repair, and production line operation and maintenance—spanning entire production lines and full systems—and possesses strong growth potential. Established in March 2022, the Company was formed through the integration of Benxi Iron and Steel Construction Company (its predecessor being Benxi Iron and Steel Civil Engineering Construction Company, founded in December 1958) and Benxi Iron and Steel Electromechanical Installation Engineering Company (its predecessor being the 24th Regiment of the Third Branch of the People’s Liberation Army Base Construction Engineering Corps, founded in May 1983). To further build a market-oriented, professional, and scaled intelligent equipment inspection, maintenance, and repair enterprise covering all directions, the Company absorbed Benxi Iron and Steel Equipment Maintenance and Repair Center in December 2023, thus accumulating stronger advantages and new impetus for high-quality development.

An industrialized application technology that has won the Second Prize of the Provincial Science and Technology Progress Award. This technology deeply couples underground salt mine extraction with soda ash production, achieving integrated above-ground and underground cyclic production of salt, alkali, and calcium. Waste liquid from soda ash manufacturing is injected into underground solution cavities for salt mining, while the extracted brine serves as raw material for soda ash production, forming a closed-loop cycle. This technical route fundamentally resolves the environmental bottleneck of waste liquid discharge in the ammonia-soda process while significantly improving the utilization rate of rock salt resources.

It has been successfully implemented in large-scale domestic projects for the comprehensive utilization of rock salt resources. The related engineering design has received First Prizes for Excellent Engineering Design at both provincial and municipal levels. This technology is suitable for soda ash production enterprises possessing rock salt mineral resources.
