ArcelorMittal Bremen orders twin-ladle furnace from Siemens VAI to boost the efficiency of the ladle treatment facility in its Bremen Steelworks Siemens VAI Metals Technologies has received an order from ArcelorMittal Bremen GmbH to supply a 300 ton twin-ladle furnace. The plant will be constructed in the works of ArcelorMittal Bremen GmbH to replace the two conditioning stands currently used for treating liquid steel. This will substantially reduce steel treatment costs. The project has a volume of several million euros. The new ladle furnace is scheduled to come into operation in February 2012.
The twin-ladle furnace will be installed directly downstream of the LD converter in the ArcelorMittal Bremen GmbH Steelworks and be designed to ensure the best possible logistic links to other parts of the plant and reduce crane movements to an essential minimum. A cross transfer ladle car will link up to the existing RH vacuum treatment unit. In addition, an ingot casting plant for producing special products will be served via a transverse track.
In future, it is intended to use the ladle furnace to treat as many melts as possible – some 3.5 million tons of crude steel per annum. Its main task will be to heat the melt, achieving a heating rate of 4 °C per minute for a 30-minute period of treatment. Optimum control of the electrodes will be ensured by the Simelt AC electrode control system. The tapping temperature on the LD converter can be reduced by between 40 °C and 60 °C, which will lower the consumption of refractory material in the converter. The ladle furnace will increase the efficiency of the ladle treatment facility, and reduce operating costs. The ladle furnace will also be able handle fine alloying work and blowing operations, which had previously taken place in the conditioning stands. The equipment supplied for this purpose will include two six-track wire feeding machines.
ArcelorMittal Bremen GmbH is a flat steel producer. It employs an integrated blast furnace / converter system to produce high-quality steel grades, primarily for the automotive and construction industries. It also intends to increase the production of tube steel grades in future.
The main reasons for winning this order were Siemens VAI's expertise in the industry and the excellent working relationship during the pre-project phase.
