At extrutec, commitment to a green future is not a matter of marketing. We create solutions for a sustainable future. This is why we have developed our Electric Resistance Heated High Convection Oven (EHKO). This purely electric heating concept achieves an industry-leading efficiency of 87% and can already be operated climate-neutrally today, under the condition that the energy used comes from 100% renewable sources.
Last week, this year's company outing took place at our location in Moos. For this purpose our subsidiary TCT Induktionstechnik GmbH from Iserlohn visited us together with extrutec North America.
In addition to the tour of our new headquarters, the boat trip on the MS Seestern on the beautiful Lake Constance, the visit to the Triberg waterfalls, the plant tour at the iron foundry Hans Dhonau e.K. in Triberg was an impressive experience. We would like to take this opportunity to once again thank Schifffahrt Lang and his team, the Dhonau company and everyone involved for the great opportunity and hospitality.
At the existing 9" press line P4 at the Hydro Vetlanda site, the entire power supply of the inductive billet heating with a total output of 3750 kW was replaced by modern, powerful IGBT converters in the summer of 2022. In addition to a new converter transformer and the protection devices for the induction reheater, which were supplied by Vattenfall, the entire power cabling was renewed and the central control system was adapted. In order to continue using the existing induction coils, the coil interconnections were modified to a single-phase system.
A newly designed ILD-type direct converter was installed at the inductive base heating, which is operated directly on the existing coil without compensation capacitors. The 3-phase coil was converted accordingly to a single-phase system for this purpose in order to eliminate the different power ratios within the coil. One challenge was the coupling of the load with a rated current of 14 kA to the converter, which is equipped with several inverters. To adjust the coil filling level to the block lengths, the coil is equipped with a length adjustment.
For the inductive reheating, a 6-zone IGBT converter of the MIB type was installed. Here, too, a single-phase system was created from a 3-phase coil in order to achieve better temperature control at the taper furnace.
This ambitious and challenging project was installed and commissioned within the 3 week summer shutdown.
Shortly after the ceremonial opening of the new P60 extrusion line in Ranshofen, HAI continues its dynamic corporate growth with a further expansion step for the Austrian site. A second 12-inch extrusion line has been ordered. extrutec will again be the main supplier for the project.
Once again, almost the entire extrutec product portfolio was ordered. Within the new project extrutec will supply a vertical log storage system, the world's most efficient gas-based billet heating system with Eco Shower Unit (ESU), stand-alone induction furnace with two-part overhead manipulator, a profile cooling system with worldwide patented Alpha Flex Technology, a fully automatic die furnace, and a heating furnace for press dies.
extrutec is very proud to continue its close partnership with Hai. The project implementation is scheduled for the beginning of 2024.
extrutec was commissioned with a special task by long-time customer Hai Extrusion Germany. The project comprised the delivery of a ten-chamber die oven system for 12" dies with fully automatic feeding by a service shuttle, which can be moved in three axes. The limited space available and the high weight of the extrusion dies posed a challenging task for the extrutec project team. Thanks to creative solutions and good cooperation with the customer, the installation was able to go into operation as planned. extrutec's ability to respond individually to customer requirements was a major benefit in this project.
extrutec company trip 2022
Last month we had the opportunity of taking the entire extrutec team including subsidiary TCT Induktionstechnik and extrutec North America on a company trip to our location in Iserlohn.
Besides the visit of the Dortmund stadium, a historical coal mine and the factory tour of TCT, the highlight of the trip was the visit to the factory of Hammerer Soest. Here all employees could see various extrutec machines in operation. We would like to take this opportunity to thank our customer Hammerer once again for this great opportunity and the hospitality.
For the coming year, a joint excursion to Lake Constance to the extrutec headquarters in Moos is planned.
The very hard to obtain US-patent protection for the ESU System has now been officially approved by the authorities of the United States Patent and Trademark Office. There was no doubt about the unique characteristic of the energy saving system developed by extrutec.
The ESU System converts the residual energy contained in the exhaust gas of the heating system into hot water and then applies it to the bars located in the feed conveyor table. The latest version of the ESU features a heat exchanger developed and manufactured by extrutec. Within the latest real time monitoring, the Eco Shower Unit saved over 18% of gas consumption.
What a day! We congratulate Hammerer Aluminium Industries on the inauguration of the new extrusion line at their headquarters in Ranshofen. We as extrutec are very proud to be able to supply the Hammerer Group with almost our entire portfolio, consisting of billet heating with Eco Shower Unit, stand-alone induction furnace, taper quench with two-part overhead manipulator, a profile cooling system with worldwide patented Alpha Flex Technology, a fully automatic die furnace, a heating furnace for press plates and a fully automatic ageing oven system with side opening doors and service shuttle.
