Chinese steel producer Rizhao Steel Group Co., Ltd (Rizhao) awarded Primetals Technologies with an order for implementing the newly developed Through-Process Optimization solution (TPO). The order compromises of the intelligent Through-Process Quality Control System (TPQC), a newly developed Industry 4.0 IT system and Through-Process Know-How (TPKH) modules. The TPO system to be installed at Rizhao´s production complex in Shandong Province will continuously monitor and manage product quality by recording all process parameters as well as measured production and product data, starting from the liquid phase up to the final processing lines.

Chinese steel producer Rizhao Steel Group Co., Ltd (Rizhao) awarded Primetals Technologies the final acceptance certificate (FAC) for three of a total of five Arvedi ESP lines. For two of the lines, the FACs where received in January, for the third one on April 1. Although the project schedule was very tight, the ambition was to complete all phases on time, what was successfully achieved. The first two lines were ordered in 2013 and went on stream within 20 and 22 months, respectively. The start-up of ESP plant 3, ordered in 2014, was achieved within 15 months. The lines are designed for a total annual production of 7.65 million metric tons of high quality, ultra-thin hot strip, in widths up to 1,600 millimeters and thicknesses down to 0.8 millimeters. The lines produce carbon steel, high-strength, low-alloy grades, and two-phase steels. The production ranging from 0.8 to 6 mm thickness is now focused on hot strip with a thickness of 0.8 millimeters, leading to production sequences in which more than 50 percent of the products have a thickness of less than one millimeter.

In February, the Chinese steel producer, Rizhao Steel Group Co., Ltd (Rizhao), rolled the first coil on the Arvedi ESP (Endless Strip Production) plant no. 1 supplied by Primetals Technologies. Earlier this year, the first casting as well as the rolling of the first plates were carried out successfully. The plant is designed for an annual production of 2.55 million metric tons of high quality, ultra-thin hot strip, in widths up to 1,600 millimeters and thickness down to 0.8 millimeters. The energy consumption is up to 45 percent lower than in a conventional casting and rolling process. The Arvedi ESP plants have put Rizhao in a position to open up the attractive domestic and foreign markets for high quality, thin-gauge products.
