New automation equipment for compact hot strip mill of Hyundai Steel, Korea
Oct 28, 2008
Hyundai Steel Co, Seoul, Korea is to equip parts of its compact hot strip mill in Dangjin with new automation. By initiating this modernization measure, the company wants to enhance product quality, extend the range of products and increase the plant’s availability.
Hyundai Steel Company operates three production sites in Korea. The company currently produces a total of approximately fourteen million metric tons of steels per year comprising carbon steel products, including reinforcing bars, angles, channels, wide-flange beams, H-beams, I-beams, rails, including light rails and elevator guide rails; casting and ingots, and cold- and hot-rolled steels. The Compact Hot Strip Mill in Dangjin has a capacity of 2 million metric tons per year and produces various types of carbon and API steel.
In the context of the current project, Siemens will supply and install the basic (incl. technological control system) and process automation (incl. PCFC) for the six-stand finishing mill and the cooling section of the compact hot strip mill. The automation equipment to be used is part of a solution developed specifically for compact hot strip mills. Simatic TDC and the WinCC visualization will be used as the basis of the system for basic automation.
HP computers will be provided for process automation. Online process models generate the presettings for the finishing mill and the cooling section and also supply the parameters for the control and adjustment algorithms during ongoing production. The new automation system will mean that the plant will be able to precisely roll and cool modern steel grades. In addition, Siemens is supplying model predicative controllers for the finishing mill and the cooling section.
The new automation equipment for Hyundai Steel is a uniform, integrated system with a high degree of standardization. Integrated diagnostic functions ensure a high level of transparency, simple operator control and fast reactions of the operating personnel in the event of any faults. The solution also features open communication protocols, thus facilitating future expansion of the equipment.
Siemens Metals Technologies is also responsible for project management and engineering of the systems and components as well as of installation supervision and full commissioning. In 2006, Siemens has upgraded automation equipment Symadyn D to TDC and auxiliary drives Simovert P to MD in the coiler area. Three casters ordered from Siemens VAI in 2007 are currently under construction.
The first coil is scheduled to be rolled in September 2010.
