Not all ore is created equal. This raw material is important in steel production – it plays a large role in determining the quality of the end product. In other words, the best ore makes for the best steel. To help regulate ore quality, thyssenkrupp has put an automated sinter test facility into operation in Duisburg. This facility is the first of its kind worldwide. Here, small batches are tested to determine the behavior of the raw material under conditions of mass production. The facility also measures emissions released during the sintering process, so that steel plant emissions can also be reduced later on.

We gladly provide free of charge the images included in our media library for use within daily use in the press (including magazines published weekly or monthly). In any case, condition precedent for this is that when using them, you refer to our company as the source in the immediate vicinity of the image material used and in the customary manner (© thyssenkrupp Steel Europe). If a different author is indicated, this must be stated. You are only authorized to process images to the extent that this is technically mandatory for the specific publication (e.g. black/white instead of in color in a monochromatic daily newspaper) and/or to the extent you only change the size proportionally, without using only part of the image, or to stretch, compress or modify it in any other way or to deform it. Every other processing and use is only admissible after prior written approval (email to: [email protected]). We request to be provided with an author’s copy free of charge and promptly after the respective publication of print media, with films with a digital version in a customary playback format on a generally readable data carrier. Where the image material is used online, you shall provide us with the detailed URL of the respective website and make this website accessible to us. close
Sintering is the process of mixing fine-grained iron ore with aggregates required for the blast furnace process (such as coke), heating it to high temperatures, and baking the product into large pieces. The resulting chunks of ‘sinter cakes’ are an important component in crude iron production. Employees at the test facility can define the ideal blend of components in the sinter cake within the shortest possible time.
Moreover, detailed dust analysis lets employees identify which materials release the fewest emissions during sintering. As such, the test facility makes an important contribution to environmental protection in Duisburg and the surrounding area.
