Recently, the extremely thin silicon-manganese spring steel of HBIS Group Tangshan Steel was successfully rolled off the production line, with a thickness of only 2.0 mm, reaching the industry limit. After testing, the product surface quality, dimensional accuracy, and other indicators all meet the process design requirements. After subsequent processing, it will be made into important mechanical components and applied in the country's high-tech fields.
Silicon manganese spring steel is a widely used alloy spring steel with excellent mechanical properties and processing properties. It also has high strength, elasticity, hardenability, and fatigue life. It is widely used in high-tech fields.
Tangshan Steel is deeply close to the market and customer needs, continues to exert its strength in the market and marketing, accurately captures the latest market information, releases the advantages of the new area, and fully promotes the research and development and promotion of high-efficiency and differentiated products, truly embodying the advantages of the new area in product competitiveness. In response to the production problem of thin silicon-manganese spring steel with high C and Mn content that is easy to break during rolling, the research team fully utilized the advanced equipment and process technology advantages of the 2050 hot rolling production line, evaluated the production line's limit production capacity, accurately allocated the load of each frame, and formulated a reasonable product rolling plan. By strictly controlling the temperature of the heating furnace and correcting the target convexity of the strip, the rolling stability was improved, and the rolling mill control model was optimized for secondary innovation to ensure a high-quality product roll-off.
