Děčín plant’s manufacturing capabilities
The cast-house operates 4 melting and casting lines with batch capacity 5 to 40 tons using both gas fired and also induction technology. Thanks to more than 70 alloys and modifications, a variety of heat treatments can be applied to achieve specific properties. Cast billets from major alloys are further treated in the billet finishing center. Billet finishing is made by ultrasonic testing, cutting to lengths optimized for the extrusion process and followed by surface scalping.
The plant consists of 3 extrusion shops with a dedicated production portfolio and capabilities. In total, 11 extrusion lines are in operation, with another coming online in 2016. Extrusion fleet ranges 6 to 35 MN with both direct and indirect technology. Extruded bars and tubes can be further treated by cold drawing based on product dimension and surface requirements. Finally, products are heat treated to achieve the required properties.
The casthouse has been extended by a dedicated re-melt furnace than enables the recycling not only of internal scrap but also the processing of customer scrap and even scrap with organics. State-of-the art technology is used to optimize the material recovery and minimize the environmental footprint.
