- Key Advantages: Hydraulic servo cylinders enable precise control of rolling parameters; dust removal equipment achieves a dust removal efficiency of 99.99%; intelligent bundling machines realize automated operations and reduce labor intensity. The circulating water treatment system delivers excellent effluent quality (suspended solids <30mg/L, oil content <5mg/L), meeting environmental protection requirements.
Core Technological Breakthroughs: Empowering Product Iteration and Upgrade
1. High-Performance Hot Rolling Technology for Extra-Large Section Steel
- Takes the lead in a national key R&D program, overcoming key technologies such as special-shaped billet continuous casting and coupled regulation of temperature-stress-strain fields. Enables the integrated forming of extra-large section steel with web height exceeding 1600mm and flange width over 500mm, reaching world-leading technical levels.
- Innovates the “3+3+1” production process: the roughing mill adopts a three-stand reversing continuous rolling flexible rolling technology, and the finishing mill is equipped with head-free tensionless rolling. The product dimensional deviation is controlled within ±0.5%, and the straightness error is less than 1/1000 of the length.
2. Core Technology for Fully Continuous Hot-Rolled Strip Steel
- Pioneers the fully continuous hot-rolled strip steel technology system, taking the lead in realizing the mass production of 1.0mm ultra-thin strip steel. Reduces the roughing rolling time from 120 seconds to 45 seconds, increasing production capacity by 30%-50% and lowering production costs by 20%.
- Cuts fuel consumption by over 20% and oxidation loss from 1.2% to 0.8%-1%, saving more than 50 million RMB in annual fuel costs and additional profits, perfectly aligning with the “dual carbon” goals.
3. High-Efficiency Continuous Casting and Rolling Technology
- Develops high-speed continuous casters with a casting speed of 3.0-3.8m/min for 165mm×165mm billets. Equipped with core technologies such as mold electromagnetic stirring, soft reduction, and secondary cooling air-mist cooling, ensuring stable cast billet quality.
- The high-efficiency shared pass technology reduces the number of roughing passes from 7-9 to 3-5, with unit steel power consumption ≤40 kWh. Both power consumption and roll wear are reduced by 25%, and the daily output of medium section steel exceeds 9,700 tons, with an annual output of up to 2.15 million tons.
4. Intelligence and Cost-Reduction & Efficiency-Improvement Technologies
- The multi-specification shared roughing roll technology allows 30 specifications to share 10 sets of roughing rolls, reducing initial roll investment by approximately 20 million RMB. Only 3 types of billets can produce more than 50 varieties of section steel, significantly reducing capacity loss and production costs.
- Builds an intelligent control center and MES production management system, integrating data monitoring, process parameter issuance, and one-click rolling functions. Realizes full-process digital collaboration and precise control of production, improving operational efficiency and product consistency.
