World’s leading engineering and plant building in metal industry – Primetals recently announced setting up of 4th ESP line for hot strip production at China’s Rizhao Steel. Fourth Arvedi ESP line from Primetals Technologies started up at Rizhao Steel in China.
At the Chinese steel producer – Rizhao Steel, the fourth Arvedi ESP (Endless Strip Production) plant supplied by Primetals Technologies was started up in April’18. The casting and rolling plant will produce 1.7 MnT of high-quality, ultra-thin hot strip with thicknesses of down to 0.8 mm and widths of up to 1,300 mm.
The product portfolio ranges from carbon steel to HSLA (high-strength low alloyed) grades. To cater to capacity shifts of Rizhao´s crude steel production and a change in plant setup, the Arvedi ESP plant was reengineered for the use of larger ladles as well as for decreased space availability during the ongoing project.
Rizhao Steel Co., Ltd. (Rizhao Steel), a company of the Rizhao Steel Holding Group, is located around 30 kilometers outside of the port of Rizhao in the south of Shandong province. The company has a production capacity of approximately 15 MnT tons of crude steel. Rizhao Steel’s product portfolio includes hot-rolled coils, wire, rods and small-dimensioned I-beams, which are mainly sold to Chinese customers. The new Arvedi ESP plants enables Rizhao Steel to further expand its production capacities for high-grade thin strip products and production of cold-rolled substitutes.
Primetals Technologies was responsible for the engineering of the Arvedi ESP plant and supplied the mechanical equipment, the media systems, technology packages and the automation technology.
Key benefits of installed Arvedi ESP hot strip line
The Arvedi ESP system produces hot strip directly from liquid steel in a continuous and uninterrupted production process in a linked casting and rolling plant.
In this type of plant the power consumption and the related costs are up to 45% less than in the case of a conventional plant with separate casting and rolling processes. It also means a significant reduction of CO2 emissions.
Furthermore, with a length of only 155 meters, the dimensions of these plants are clearly more compact than those of conventional casting and rolling plants.
