50t ESR plant for Metal Ravne, Slovenia
After the successful start up of one of the first ESR plants at Metal Ravne in 1981 by INTECO, which still produces at maximum capacity, in August 2010 the contract for another plant was signed.
The new project consists of a combined static- and short collar mold ESR plant producing ingots with a max. weight of 50t and a max. diameter of 1400 mm. The new plant by INTECO is equipped with state of the art technology such as a protective gas hood, coaxial design and an innovative control system etc.
The implementation of the current conductive mold (CCM®) is scheduled for a later point of time. The excellent cooperation and teamwork of INTECO and Metal Ravne will be again strengthened through this new project.
ESR furnaces for Dongbei Special Steel, China
In the record-breaking year 2008. INTECO has been awarded with contracts for two ESR furnaces by the Chinese customer Dongbei special steel. The smaller 36t plant, which is designed for production of ingots with a max. diameter of approx. 1000mm, and the 100t furnace capable of remelting max. 1750 mm dia. ingots set another highlight in INTECO´s reference list. Both plants are designed for conventional Short collar mold/retractable baseplate technology with the option of applying INTECO’s patented CCM© technology at a later stage.
ESR furnace for TISCO, China
INTECO is proud to announce that a contract for engineering, supply and commissioning of a 16t static crucible ESR plant with three melt stations has been concluded with this esteemed customer. The plant will be capable of remelting 1100mm diameter ingots produced either with or without electrode change technology. A split power supply concept enables simultaneous remelting in two out of three melt stations served by two fully equipped furnace heads.
Two ESR plants for confidential costumers, Europe
In summer 2008 two more big-sized ESR furnaces have been contracted to INTECO. Both furnaces will be operated with electrode change technology executed in static crucibles. Due to a special power supply and control concept simultaneous single-electrode remelting is possible in additional melt stations.
The plants are designed for production of ingots with a max. weight of 250t (dia. 2600mm) and 110t (dia. 1900mm) respectively and will definitely set new standards in the world of Electro-Slag Remelting.
ESR plant for Saarschmiede, Germany
At the end of February 2008 INTECO was contracted to carry out the design and supply of a 145t ESR plant by Saarschmiede GmbH in Germany. This plant consists of three identical furnace heads and four melting stations, three of them can be operated simultaneously and independently of each other. As an additional option, the plant can be equipped and operated with INTECO's patented current conductive mold CCM©.
This innovative plant concept, which stands out due to its high level of flexibility, was started up in summer 2010 as the ESR plant with the worldwide biggest production capacity of approx. 20,000t/year. After a great number of successful melting processes producing ingots of high quality, the Final Acceptance Certificate has been signed by the client in early 2011.
Laboratory ESR-VAR plant for ALLVAC, USA
This is a combined laboratory ESR-VAR plant for ALLVAC in the US. The plant was ordered at the beginning of the 2008 business year and has been delivered in spring 2009.
Pressure ESR plant for CARPENTER Technology Corp., USA
In July 2007 INTECO was contracted to deliver an innovative pressure ESR plant for the production of high nitrogen special steels. This plant with its new and innovative concept of high current feed and return line is unique in the field of pressure ESR. The plant was engineered and delivered from August 2007 to November 2008. Commissioning of the plant is finished, and protective atmosphere as well as pressurized ESR melts have already been carried out successfully and to the full satisfaction of CARPENTER.
ESR plant for RADOMIR Metals, Bulgaria
This ESR furnace consists of a short collar mold melt station and one central withdrawal station served by two fully equipped furnace heads.
