In the industrial zone of Xinfeng Town, Nanhu District, Jiaxing City, Zhejiang Province, the construction site of the Green High-end Nickel-Chromium New Material Intelligent Manufacturing Project is a scene of intense activity. The hum of machinery blends with the diligent work of the crew, focused on building a global benchmark production line for ultra-thin hot-rolled materials and zero-carbon manufacturing.

"The project includes a billet steelmaking system, along with complete process lines for hot-rolled coil and plate, annealing and pickling, cold rolling, and special smelting equipment. This represents a significant capacity increase compared to the original setup," said Zhang Zhongliang, Project Manager for the Steel Rolling Area of the project. He emphasized that MCC Huatian approaches the project with a profound sense of responsibility, adhering to the principles of "high standards, strict requirements, and meticulous execution." The focus remains on quality, innovation, and service, with steady progress toward the target of completion and delivery in 2026.

"We are targeting technological breakthroughs and green transformation through three pioneering innovations," explained Lin Zequan, Chief Designer of the project. First, the flexible adoption of both the "Electric Arc Furnace + AOD Furnace" two-step and "Electric Arc Furnace + AOD Furnace + VOD Furnace" three-step steelmaking processes for stainless steel enables a pioneering multi-grade, high-quality flexible smelting technology. This innovates the green and intelligent short-process production for nickel-chromium new materials. Second, the innovative integration of equipment like the thick plate mill, hot coil box, and wide-strip continuous finishing mill creates the world's first flexible, customized, and co-existing production line for ultra-thin and ultra-wide plates and coils. This breaks through efficiency and specification limits in stainless steel manufacturing, achieving full coverage of mainstream market products. Third, centering on the "Zero-Carbon Factory" vision, environmental indicators are integrated throughout the entire process. The pioneering full-oxygen green power zero-carbon technology is implemented, with a plan for 100% green electricity usage, fulfilling the commitment to a zero-carbon industrial park.

"The steel plate silo project marks Oriental Special Steel's first use of silos for lime storage, replacing the traditional manual feeding method. It is also MCC Huatian's first design, fabrication, and installation project for steel plate silos," said Yang Jian, Project Manager for the Lime Steel Plate Silo Project. Each silo has a diameter of 13 meters and a height of 12.3 meters. The six silos provide a total storage capacity of 5,100 tons and can simultaneously meet a conveying rate of 200 tons per hour. Unlike the sequential construction of typical concrete silos, these steel plate silos were installed using the inverted method. By leveraging the company's professional technical expertise, a reliable installation plan was developed, ultimately employing DHP chain electric hoists. The hoists were activated simultaneously via central control for a uniform lift of the silo structures, completing the process safely over one month.

"The Central Water Treatment Project is MCC Huatian's first zero-discharge benchmark project for industrial wastewater and represents a major breakthrough in the advanced treatment and resource recovery of high-difficulty industrial wastewater," said Li Yecheng, Project Manager of the EPC contract for the Central Water Treatment System. The clean water and wastewater pretreatment equipment have already arrived on-site for installation. It is expected to be capable of supplying water to the steelmaking process by April this year, with overall completion targeted for July. The project adopts an advanced combined process of "Pretreatment + Multi-Membrane Integration + Evaporation Crystallization." Specifically addressing the characteristics of stainless steel industry wastewater—high salinity, high hardness, containing heavy metals and complex pollutants—it achieves 100% wastewater recovery and reuse, along with resource recovery of crystallized salts, truly realizing the "zero discharge" goal. Highly aligned with national green manufacturing and circular economy development strategies, the project possesses significant high-tech features and demonstration value, with outstanding environmental and economic benefits. Furthermore, the project team collaborated with the owner on R&D, integrating multiple core high-tech applications and accumulating valuable core technical experience and engineering data. This fills a gap in MCC Huatian's portfolio in the high-end environmental technology engineering field, marking its advancement to the forefront of the industrial wastewater treatment sector. It demonstrates the capability to provide comprehensive water system solutions for large enterprises and emerging industries, laying a solid foundation for future expansion in similar markets.

The project's product portfolio targets high-end materials, including heat-resistant steel and super austenitic stainless steel. Upon completion, it will become the world's first flexible stainless steel smelting and rolling demonstration production line, achieving breakthroughs in 20% import substitution and 50% high-end products. This will effectively address the "bottleneck" challenges in the domestic, efficient manufacturing of high-performance nickel-chromium materials. By integrating metallurgical and environmental technology advantages to innovate stainless steel smelting and build the world's first fully green-powered, zero-emission nickel-chromium material intelligent manufacturing factory, the project is poised to become a dual benchmark for ultra-thin hot-rolled materials and zero-carbon manufacturing. It will empower the intelligent and green upgrade of the stainless steel industry, set a benchmark for green transformation within the national steel sector, and contribute to the national "Dual Carbon" goals.
