[Rizhao Steel No.7 Pickling and Rolling Line Upgrade and Transformation]
To deeply tap the line's potential and optimize the product mix, Rizhao Steel recently completed a comprehensive upgrade of its No.7 pickling and rolling line and added a continuous rolling mill. After the transformation, the line's designed annual capacity has been raised to 1.2 million mt, achieving a significant improvement in large-scale, specialized production capability. Since the project was put into operation, production and technical positions have worked closely together to overcome multiple process bottlenecks and successfully achieve product iteration for medium- and high-carbon steel lean coil products. From May to August this year, the line has stably mass-produced multiple grades of high-quality medium- and high-carbon steel products for saw blades, yielding fruitful phased results from the technological transformation, upgrade, and new product development.
