Bar production
The extensive application of high-speed bar production lines in rebar projects. In 2014, our company proposed the use of a modular finishing mill group, which achieved temperature control and rolling technology in high-speed bar production. At the same time, the modular arrangement of the mill makes the product outline of customers more flexible. The extension of the back-heating section is conducive to the optimization of the internal organizational performance of steel. Most importantly, the modularized electrical control system has increased the production speed limit, meeting customers' high requirements for both quantity and quality.
The production line can produce ordinary steel and low-alloy steel rod materials, as well as alloy steel rod materials such as bearing steel and gear steel.
The production line can produce specifications of Φ8 - Φ40 mm, and the products are delivered in the form of straight bars bundled together.
The production capacity of the production line can reach 1 million tons per year.
The production line adopts single - strand rolling, and the designed rolling speed is 45 m/s.

Temperature control and rolling control
Control of temperature and rolling is a core technology in steel production, critically determining the mechanical properties, micro structure, and final quality of steel products. By leveraging digital technologies to achieve automated management of temperature and rolling control, product consistency can be significantly improved, energy consumption reduced, and human errors minimized.
The application of digital steel mills has shifted from breakthroughs in single-point technologies to full-chain collaboration. Its core value is reflected in five key dimensions: efficiency, quality, cost, safety, and sustainability. In the future, with the maturation of technologies such as AI-driven autonomous decision-making and 5G fully connected factories, the steel industry will accelerate its transformation towards "unmanned, zero-carbon, and high-end" development.

High-speed wire rod production has always been a major part of steel products. Such products have a wide range of applications, a broad selection of materials, and high precision requirements. The wire rod production line provided by our company can achieve a line speed of 110 meters per minute when producing products with a diameter of 5.5 mm, with a maximum daily output of up to 1,500 tons. Meanwhile, our company is also the first in the world to introduce the technology of hot-rolled deep processing to produce 2.5 mm steel wire. In addition, our technical scope also includes nickel-iron alloy rolling and copper wire rolling mills.
As a commonly used building and industrial material, profiled steel products come in a wide variety of dimensions, specifications, and styles. The raw material, steel billets, also varies in specifications. Therefore, in the design of profiled steel production lines, it is essential to maximize the rolling production of multiple specifications of profiled steel on a single production line to reduce customers' investment costs. Additionally, integrating an intelligent roll-changing mechanism can further enhance the efficiency of the production line. Our company undertakes the general contracting projects for production lines of various sizes of profiled steel and has successfully achieved co-line production of symmetrical profiled steels such as rod materials, H-beams, and angle steels.
Equipment upgrade and revamping
Our company boasts a complete industrial chain covering the design, R&D, and processing manufacturing of metallurgical equipment. We are capable of customizing equipment replacement solutions based on the actual site conditions and infrastructure of our clients, aiming to minimize their investment costs to the greatest extent.
Our company provides customers with services to analyze the mechanical structure of their existing equipment, and offers redesign services for spare parts and assemblies. At the same time, we can also provide customers with a zero-inventory solution to reduce the total cost of spare parts, which is mainly implemented through three systems. 1. Unified management of spare parts supply chain to ensure an effective inventory level and recycle waste spare parts. 2. Unify spare parts quality standards to ensure the service life of spare parts. 3. Collect key data to detect potential risks in advance, thereby reducing abnormal downtime.
Our company has the capability to complete blast furnace EPC projects with a volume ranging from 1,080 cubic meters to 2,000 cubic meters. We can also provide blast furnace coal injection systems and related equipment. Additionally, we offer spare parts assemblies such as blast furnace water-cooled valve rods, hot blast stove tuyere sleeves, mud guns, and slag scrapers.
