Accelerated tough technological transformation, intensified low-carbon transition!

In May 2026, the energy-saving approval for the low-carbon refining technology upgrade project of Jinhai Stainless Steel in Wuzhou, Guangxi was officially granted. This marks that this core upgrading project focusing on high-end, green and high-quality aspects has entered the stage of substantive construction and implementation.

The project centers on the upgrading of vacuum refining technology, aiming to fill the gap in high-end stainless steel raw material production capacity, fully tap the potential for energy conservation and carbon reduction, and comprehensively promote the leapfrog upgrade of the regional stainless steel industry from "large quantity" to "high quality, low-carbon and high-end".

01 Project is completely upgraded | Dual workstation VOD refining, with an annual production capacity of 500,000 tons of low-carbon stainless steel water

The construction period of this Jinhai Stainless Steel Low-Carbon Refining Technological Transformation Project is from 2026 to 2028. The core construction contents include a complete set of dual-station VOD vacuum refining furnaces and their supporting auxiliary facilities, an environmental protection and energy-saving system, and an intelligent control system. The process configuration is advanced, the equipment is highly integrated, and the intelligence level is high.

After the project is completed, it will achieve a stable annual production capacity of 500,000 tons of low-carbon stainless steel water. This will provide high-purity and high-quality raw materials for subsequent high-end stainless steel processing and fine rolling, effectively connecting the entire high-end production chain of "refining - casting and rolling - finished products", and further improving the integrated industrial layout of Jinhai Stainless Steel.

Compared with traditional refining processes, VOD vacuum refining technology is the core key process in the production of high-end special steels.

Through a vacuum sealed refining environment, harmful impurities such as carbon and sulfur in the steel can be precisely removed, significantly improving the purity, uniformity and stability of the steel quality. This helps to enhance the performance of stainless steel materials from the source, laying a solid foundation for the production of high-end special steels.

02 Quality Upgrade | Precisely Adapt to High-End Special Steel Scenarios Such As 316L and Duplex Steel

With the rapid iteration of industries such as new energy equipment, marine engineering, precision manufacturing, high-end hardware, and medical devices, the market demand for high-purity low-carbon stainless steel, corrosion-resistant duplex steel, and high-quality 316L series special steel has continued to rise. The shortage of high-end raw materials and unstable quality have always been the key pain points restricting the improvement and efficiency enhancement of the regional stainless steel industry.

In this technological transformation, Jinhai has precisely targeted the high-end market demands. Utilizing the high-purity raw materials produced through the vacuum low-carbon refining process, it can fully adapt to the production of high-value-added special steels such as 316L stainless steel and duplex stainless steel. The products have a wider range of applicability and better performance indicators, which can fully meet the strict material standards, corrosion resistance standards and safety standards of the downstream high-end manufacturing fields, and help the downstream industries upgrade to a higher level.

03 Achieving Dual Breakthroughs in Cost Reduction and Energy Conservation | Technological Innovation Enables Low-Carbon and High-Efficiency Production

This technological upgrade is not only a quality improvement, but also a profound transformation towards green and low-carbon practices, as well as cost reduction and efficiency enhancement.

On the one hand, the new vacuum refining process can effectively optimize the alloy composition structure, significantly reduce the loss of high-value raw materials such as nickel iron during smelting, increase the utilization rate of raw materials, effectively reduce the production cost of high-end steel, and enhance the market competitiveness of the enterprise's products.

On the other hand, the new processes and equipment enable precise control of smelting energy consumption. The energy consumption per ton of stainless steel produced has significantly decreased. The pollutant emissions throughout the production process have become more stable and controllable, fully meeting the requirements of the ultra-low emission transformation in the steel industry. It deeply aligns with the national "dual carbon" strategy and the industrial green transformation and development orientation. Truly achieving a comprehensive benefit of improving quality, increasing efficiency, reducing costs, and lowering emissions.

04 Empowering Regional Industries | Addressing the Core Shortcomings of High-End Stainless Steel Raw Materials in Guangxi

As an important hub for the stainless steel industry in South China, Guangxi has a prominent scale advantage in the stainless steel industry. However, there have been long-standing shortcomings in the industry, such as insufficient self-sufficiency rate of high-end raw materials, weak production capacity of special steel, and a product structure that is mainly in the mid-to-low end. A large amount of high-end stainless steel raw materials rely on external supply, which has restricted the extension of the regional industrial chain to higher value-added links.

The implementation of this low-carbon refining technological transformation project by Jinhai Stainless Steel has significant implications.

After the project is put into operation, it will significantly enhance Guangxi's independent supply capacity of high-end low-carbon stainless steel raw materials, fill the gap in local high-end refining capacity, improve the all-round industrial support of Wuzhou Stainless Steel Industrial Park, and drive the regional stainless steel industry to break away from "low-end homogeneous competition", and move towards a brand-new stage of high-quality, high-end, green and intelligent development.

Relying on this technological transformation and upgrading, Jinhai Stainless Steel will continue to consolidate its core production advantages in high-end stainless steel in South China. It will empower quality improvement through green processes and drive the upgrading of the industrial chain with high-end production capacity. It will continuously inject new momentum and vitality into the high-quality development of the steel and stainless steel industry in Southwest China.

In the future, Jinhai Stainless Steel will continue to focus on process innovation, low-carbon technological transformation, and product upgrading. It will deeply engage in the high-end special steel sector, adhere to the green intelligent development path, and establish a benchmark for high-quality development of the regional stainless steel industry.
