Siemens VAI Metals Technologies has received an order from Canadoil Plate Ltd. to supply equipment for a new 5 meter plate mill in Thailand. The order value is a three-digit-million-euro figure. The heavy plate rolling mill is designed mainly for the production of plates required in manufacture of high grade pipe, pressure vessels and structural steels for the energy industry. The plate mill will be able to roll finished widths of up to 4.9 meters and is scheduled to start operating in 2010. With this project, Siemens is expanding its leading position as a supplier for plate mills.
Located in Bangkok, Thailand, Canadoil Plate Ltd. is part of the Canadoil Group, a leading manufacturer of components for the energy industry including main transmission pipelines for the oil and gas industry as well as specialty piping components for the power and water treatment industries. The Group specializes in the manufacture of a very wide range of pipes and fittings with diameters from 1/2” to 120” in all types of ferrous and non-ferrous materials. Canadoil also manufactures static equipment such as pressure vessels, reactors, filters, heat exchangers, launcher receivers and slug catchers and all of the prefabricated piping spools and modules required to create large scale industrial plants in the petrochemical, power, water treatment and mining industries.
For the new 5.0m plate mill Siemens is supplying a high pressure descaler, finishing mill stand with a maximum rolling force of 10,000 tonnes, comprising of a hydraulic roll gap control system and SmartCrown work roll bending and shifting system. A Mulpic intensive cooling system with a pre-leveller, a hot plate leveller, a shearing line and a cold leveller complete the mechanical equipment supply. Siemens are also supplying the engineering for all the remaining roller tables, cooling beds, transfers and basic engineering for the required utilities.
In addition to the mechanical equipment, Siemens is supplying all the electrical equipment and the automation system, including the sensors. The roll stand is driven by two cylindrical-rotor synchronous motors using Sinamics SM 150 DC link converters with a rated output of 28 MVA. The automation system includes the basic automation, the technological control systems and the process automation as well as the HMI system and a higher-level production planning and control system (level 3). This solution supports all production methods for modern steel grades such as Plan View Control, thermo-mechanical and nested multiple-plate rolling, to increase the productivity of the rolling mill. The system can be flexibly adapted to changes in the range of products or the quality requirements and thus offers protection for the necessary investment involved. On top of this, it plans and ensures a smooth flow of materials along the entire production process – from takeover of the slabs to delivery of the customer-specified steel plates. All the components and systems used are part of Siroll PM, the integrated solution for plate mills. Siemens is also responsible for commissioning and customer training.
