INTECO to built new VAR plant for BGH Lippendorf

After a short but productive negotiation period, an order for engineering and supply of a 10,5 t Vacuum Arc Remelting Furnace (VAR) was placed by BGH Edelstahl Lippendorf GmbH.

The first INTECO plants for this longterm costumer were delivered in the 90s and as a result of close cooperation as well as excellent and fair teamwork the German special steel manufacturer again chose an INTECO solution. The VAR furnace is designed according to the latest technology and is equipped with a drip short control, a helium cooling system and the possibility to execute partial pressure remelting.

The installation of this project will start in October and the production of the first ingot is also scheduled for 2014.



First Heat at Deutsche Edelstahlwerke Witten

In January 2014 the first heat at the new secondary metallurgical centre at Deutsche Edelstahlwerke Witten was carried out. The melting process on the new treatment line’s ladle furnace and VD/VOD plant was realized without any major difficulties and delays.

This was the first important milestone of the start up phase, which took place according to schedule.

The first part of this large scale project comprised the revamping of the existing secondary metallurgical line and was finalized mid of 2012.



Start Up at Buderus Edelstahl GmbH

INTECO successfully commissioned the new material handling system for the secondary metallurgical plant at Buderus Edelstahl in Wetzlar (Germany) end of August 2013.

In addition to the supply and installation of the new alloying plant INTECO replaced the control and visualisation system of the existing material handling plant. The new entire complex is now also integrated into the steel plant‘s Level 2 system.

With the implemented extension of the alloying system it is now possible to charge additives simultaneously into the EAF as well as into the refining units.

The emphasised close cooperation between Buderus Edelstahl, INTECO and its subsidary INTECO atec automation was the key for a successful completion of the project in due time.




ESR plant at Ruspolymet

INTECO is very proud to announce that the contract for the ESR plant signed with Ruspolymet has become effective by October 2013.

This most modern unit will feature all state-of-the-art features such as protective gas operation, full coaxial high current line and a completely updated control system of newest generation. This plant will be designed in a most flexible configuration enabling the operation in collar molds (with electrode change) with a retractable base plate as well as in static molds (single electrode remelting).

Most of the electrodes will be produced in INTECO´s VIM furnace which will be already in production at the time when the ESR plant will be started up. The maximum ingot dimension has been defined with diameter of 750mm and a maximum weight of approx. 10 tons.

Following the request of Ruspolymet, INTECO shortened the delivery time by two months and will delivery this unique ESR furnace in May 2014.


Dongbei Special Steel signs FAC

End of September 2013 Dongbei Special Steel signed the Final Acceptance Certificate (FAC) for the two ESR plants engineered and supplied by INTECO.
