Strong as steel

Even 1,750°C is no burning problem for immersion sensors from Heraeus

The development departments of this Heraeus business segment, with its headquarters in Houthalen, Belgium, design a wide range of custom sensors for use in direct contact with molten steel, combining them with traditional measuring methods. An on-site report.
At the entrance to Heraeus Electro-Nite’s Belgian site at Houthalen, visitors are welcomed by a knight in armor and carrying a lance – the symbol of the division’s main products: lances and immersion sensors for the steel industry. Heraeus Electro-Nite has been operating as a market leader for many years in the steel industry, as well as in the foundry and primary aluminum industries. The site’s rather discrete production facilities are the setting for the development of innovative sensors and measurement systems. Every aspect of the production process, some of which is fully automated, is carried out in one place: quality assurance, the ceramics laboratory, the oxygen center, and the most advanced facilities for testing sensor functions. There is ample space for engineers to develop new projects in an open-minded atmosphere.

The steel market is booming. In 2006 alone, over 1.2 billion metric tons of steel were produced worldwide. In order to ensure quality, the temperature and chemical composition of molten steel and iron needs to be measured at regular intervals. Elongated immersion sensors from Heraeus Electro-Nite measure these parameters rapidly and accurately.
