Uddeholm orders second ESR plant at INTECO

After the successful signing of the final acceptance certificate for the first 30t ESR plant delivered within a year, Uddeholm asked INTECO to build another identical remelting furnace.

Mid of May INTECO received the order for the engineering and supply of an ESR plant from the world’s biggest high performance tool steel producer Uddeholm in Sweden.

The second plant is an identical copy of the 30t INTECO ESR furnace that has already been successfully started up in April this year. Again, the new plant design for a static mould configuration that has been developed throughout the last years will be implemented. It allows protective gas operation within a pressure range up to three bar.

A smooth project process, delivery and start up on schedule where the drives of success for the first ESR project and will be also essential for this follow up project.

INTECO acquires majority shares of SPT Swedish Process Technology AB

Metal Ravne orders EAF Revamping at INTECO (Kopie 1)

In March METAL RAVNE has awarded INTECO with the complete revamping of its 1991 FUCHS EAF furnace.

INTECO will convert the old 45t EAF into a furnace matching today’s technology standards by implementing state of the art injection technology, a new SwingDoor, an off gas pressure monitoring system, as well as a new automation system, the ISEC electrode regulation system and a robotic device for temperature and sampling.

The revamping will lead to a higher operator safety, an increase of the overall performance and a fully reproducible and customizable EAF process control which is crucial for high quality steel plants, where the steel grades and related operational practises change at every heat.

The project will be carried out by INTECO special melting technologies supported by INTECO PTI for the injection technology as well as the SwingDoor and by INTECO atec automation for electrical-, and automation engineering as well as the electrode control. It is a great opportunity for INTECO to show the varied skills of the group members and most importantly the competence, expertise and teamwork available for the customer. Due to the long-term relationship with Metal Ravne and the great cooperation throughout the past years a successful commissioning of the EAF furnace beginning of August 2015 can be assured.

INTECO sends kids to Graz to build the change with Lego

Visions become reality: Sponsored by INTECO over 20 students of the Bruck highschool were sent to Graz for the Lego “Build the Change “ event. There the kids were asked to show how they imagined their future with Lego bricks. “Build the Change” is a concept developed by the Danish Lego Group to give kids a voice.

The federation of Styrian industries brought this event to Graz. 4 days over 7000 kids had the chance to build their future with about 10 Million bricks.

Also INTECO’s employees’ kids took the chance an participated in the fun.




Ruspolymet places second follow-up order for INTECO

In June 2014 the Russian special steel producer Ruspolymet assigned INTECO with the engineering and supply of a 6t VAR plant.

This is already the second follow-up order for INTECO:  This new VAR furnace follows the 10t ESR plant sold in fall 2013 and the 2012 VIM project. The VIM is already being assembled and the ESR furnace is about to be delivered. Obviously there is no better evidence of the customer’s satisfaction with INTECO’s up to date work than placing this new order.

The highly modern vacuum arc remelting furnace will remelt the electrode produced by the VIM furnace and give Ruspolymet the opportunity to in future open up foreign markets. The produced ingots will have a max. diameter of 700 mm and an approximate weight of 6t. Furthermore the newly developed INTECO Level 2 system will allow Ruspolymet to administrate, metallurgically guide and optimize the whole process chain – VIM, ESR, VAR.

Right now Ruspolymet and INTECO are discussing further joint projects and a possible future strategic partnership.


The 5th annual INTECO ASMET award was presented at the ASMET Forum gala dinner in Leoben. The winner Martin Egger won the first price with his doctor thesis. Second winner was Jakob Six and 3rd Dominik Schöne. The winners share price money of 4000 Euro.

A new and promising cooperation

The future cooperation between INTECO Group and Henan Xibao Metallurgy Materials Group Co. Ltd. was finalised and contractually stipulated in spring 2014.

Xibao is a group of companies with 3500 employees and one of the largest and leading manufacturers of metallurgical consumer goods on the Chinese market. The product range of the production company located in the Chinese province of Henan ranges from ferroalloys, refractory materials and casting powder to different types of slag, especially pre-melted slag for the ESR business. 210 steel plants in more than 20 countries are already purchasing products from Xibao.

Both companies stand to benefit from the joint cooperation agreement. TECTRADE will assume responsibility for the exclusive distribution of ESR slag and selected products in Europe for Xibao. As a global market leader in the construction of ESR plants, INTECO will use its existing contacts and  focus on the distribution of ESR slag, among other things. Xibao will offer technical sales support for the “Smart ESR” plant designed by INTECO and its subsidiary in Dalian specifically for the Chinese market.

Dr. Harald Holzgruber, CEO of INTECO, is also pleased about the cooperation: “Xibao and INTECO will both benefit from each other’s networks. There is also a great deal of mutual trust involved in this cooperation as the products of both companies stand for high quality and customer satisfaction.”



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.

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
