INTERNATIONAL SUCCESS FOR KUTTNER IST Contract for the design, development, construction and commissioning of a dual-chamber aluminium melting furnace for slightly contaminated scrap from China In the hard-fought market of plants for the aluminium recycling industry, IST (Industrieofen + Stranggieß – Technik GmbH, Alfredstrasse 28, 45130 Essen, Germany) has had a successful track record. Despite renowned competition, IST has distinguished itself through a convincing design for a furnace for the melting of slightly contaminated scrap, as well as chipping and trimming scrap. This design is a variation of the standard dual-chamber furnace concept. The furnace is equipped with a modern and energy-efficient regenerative burner system, which assures low energy consumption when combined with the standard IST HDFLEX furnace door system and the EEI furnace pressure control flap. Internal afterburning and adherence to applicable environmental standards are as much an integral part of the plant as the use of the latest EMP system with chargewell.

ALERIS, Rio Tinto and TRIMET amongst its many satisfied customers. IST does not stand for the engineering and delivery of new plants. Instead, it focuses on the modernisation of existing melting and casting plants. In addition to the purely technical optimisations, the HDFLEX sealing door system developed by IST should also be mentioned. It has been installed and used by numerous renowned operators and contributes to a sustained reduction in energy consumption and maintenance expenditures.

This specially developed flap provided with highly-resistant FF material has already been installed in numerous plants both domestically and internationally and has already provided as many as three years of service in individual cases. IST has also established itself as leading company in studies for the optimisation of furnace handling, such as charge optimisation, process optimisation and observations for preventative maintenance, as well as the training of plant operators.

The furnace plant is regulated according to a strict PROSTEP process stage control system developed by IST and thereby provides a high level of operational and workplace safety. IST stands for modern design and development of the latest technologies in the area of furnace construction and can count wellknown companies like Hydro,

furnace pressure regulating flap.

An additional technical development from IST in regard to energy savings is the type EEI

We would be glad to help with the implementation and solution of your tasks.
