Siemens has received an order from PT Krakatau Steel of Cilegon, Indonesia, to completely modernize its slab steel works no. 1. The project’s goal is to increase the production capacity and reduce the specific consumption of energy and operational resources.
The order has a value of about 60 million euros. The modernized works is scheduled to come into production in the summer of 2012.
Krakatau Steel—the largest steel producer in Indonesia—produces some 1.5 million tonnes of direct reduced iron and 2.4 million tonnes of raw steel per annum in its integrated steel works. This is then further processed to make hot and cold-rolled coils and bar steels.
Slab steel works no. 1 will be renovated to expand the hot-rolled coil production to 2.4 million tonnes per annum. At the same time, Siemens will install new electrical and automation equipment in the hot strip mill.
Siemens is responsible for the design, engineering, procurement, and the turnkey installation of all new and modernized components of the slab steel works, and will coordinate the necessary constructional measures. Raw steel is produced in the works by four electric arc furnaces, three of which will be completely replaced during the project. Siemens says this will not only increase reliability and productivity but also reduce the consumption of electricity, electrodes, and refractory materials.
The associated dust cleaning systems will be modified as well; their cleaning capacity and availability are to be substantially increased. The project also includes the conversion of the two continuous slab casters CCM 1 and CCM 2.
Siemens will completely renew secondary plant equipment—such as the water treatment and the oxygen, argon and compressed-air supply systems—to meet the capacity and availability requirements of the modernized works.
The project is being implemented jointly by Siemens VAI Metals Technologies and PT Siemens Indonesia. Siemens Indonesia is responsible for the complete electrical and installation engineering, including the associated constructional measures and local procurement.
