Qianben Steel's ultimate thin specification silicomanganese spring steel has successfully rolled off the production line, the thickness of which is only 2.0mm, reaching the leading level in the industry. After testing, the product surface quality, dimensional accuracy and other indicators are in line with the process design requirements.

Silicon-manganese spring steel is a high-end product with high elastic limit, fatigue strength and strong plasticity and toughness, and also has excellent properties such as conductive, non-magnetic, high temperature resistance and corrosion resistance, which can be widely used in automotive and machinery manufacturing, electronic components manufacturing and other fields.

Qiansteel is deeply close to the market and customer needs, accurately captures the market frontier information, releases the advantages of the new area, and pushes forward the R&D and promotion of differentiated products.

For the thin specification silicomanganese spring steel C, Mn content of high rolling easy to pull off the production problems, the team give full play to the 2050 hot rolling production line advanced equipment and process technology advantages, the line limit production capacity assessment, accurate distribution of the load of each rack, the development of a reasonable product rolling plan, through strict control of the heating furnace temperature, correction of the strip target convexity, etc., to improve the stability of the rolling, and to the The mill control model was optimized by secondary innovation, which ensured the high quality of the products.
