[Rizhao Steel No.7 Pickling and Rolling Line Upgrade and Transformation]

Published: Sep 14, 2026 11:20
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.

[China's First Garrett Coiler Completes Hot Commissioning]
Recently, the Garrett coiler independently developed by Qingdao Leiting Heavy Industry Co., Ltd., the first of its kind in China, successfully completed hot commissioning and passed steel on the first attempt at Severstal in Cherepovets, Russia. All equipment operating parameters and coil forming indicators met the standards, marking a major localisation breakthrough in China's core coiling equipment for large bar coils and a successful entry into the high-end metallurgical market outside China. The Garrett coiler is the core key equipment of large bar coil production lines, and its core technology has long been monopolised by overseas producers. To break through the technical barriers, the Leiting Heavy Industry R&D team carried out sustained research, completing multiple technical innovations in structural optimisation, coil stripping mechanisms, and automatic control logic, and obtained a series of independent patents. The team overcame industry pain points of conventional models, such as unstable coil shape, coil stripping jams, and poor reliability under high-temperature conditions. The equipment is adaptable to twist-free, tension-free coiling of multiple wire rod specifications, with neat coil forming, stable operation, and convenient maintenance, fully meeting the continuous production needs of steel mills in China and overseas.

[Existing Home Sales Model Changes Land Auction Logic, Real Estate Companies' Investment Decisions Become More Refined]
Recently, the Ministry of Housing and Urban-Rural Development and two other departments jointly introduced new policies to orderly promote the existing home sales policy for commercial housing, with newly listed land parcels prioritized for existing home sales and presale projects required to have main structures topped out. Since the new policy took effect, Beijing, Shanghai, Shenzhen, Guangzhou, Xi'an, and other key cities have successively completed their first round of land auctions, with the land auction market showing intensified differentiation and restructured logic. Industry experts interviewed believe that the new policy has changed the criteria by which real estate companies evaluate land acquisitions—location, supporting facilities, floor area ratio, and product adaptability have become key variables determining project success. Real estate companies are shifting from the high-turnover era's "calculating turnover and scale" approach to "calculating individual projects and products." Currently, detailed implementation rules for existing home sales policies in various regions are still being researched and formulated, with some cities expected to release detailed rules in the next one to two months. From the market side, enterprise side, to the policy side, the impact of the new policy on the land market is gradually unfolding.
