Our products and services meet the highest quality standards and we can be reached at short notice.
Installation & start-up operation
Filter box liners
Our filter box systems are used in aluminium DC and continuous casting. We provide expert support throughout the entire process, from the initial design through the complete engineering and production in-house to the installation, start-up, and operator training. One of the features of our filter box systems is their easy use and robustness. They also have low heat losses combined with a low steel housing temperature. We supply filter boxes with gas heating systems, or, as an alternative, with electric heating systems to preheat the ceramic foam filter. Our filter box systems also have a modular design. This means that the filter box body, lid (with lid stand), pre-heating system, and stand are independent of each other. This makes a rapid replacement between two casts possible. Our filter boxes are available in all standard sizes 7“, 9“, 12“, 15“, 17“, 20“, 23“, and 26“. In general, all filter boxes are produced in accordance with our customers’ individual requests, so customized solutions are also possible.

We supply launder systems for aluminium DC casting as a complete package. This includes the selection of a suitable launder cross section, the complete engineering, manufacturing, and, if desired, the installation on site.
All our launder systems are optimised for a minimised heat loss, low steel housing temperature, and a calm metal flow. If requested, the launders can be equipped with covers and a pre-heating system. Our launder covers with electric heating allow the launder system to be preheated prior to casting. This minimises the heat loss during the initial casting process.
Our wide range of launder segments includes small segments for continuous casting, large segments for billet and rolling ingot casting as well as transfer launders. The right launder cross-section is selected in consideration of the given casting speed. If operated and maintained properly, our launder segments will achieve an excellent service life combined with minimal maintenance costs and a quick return on investment.

Large pre-cast shapes
In addition to ‘standard components’ such as filter boxes, launders, casting spouts, and hot top rings, we also manufacture large pre-cast shapes for applications in aluminium casting. This includes liners for deep bed filters, degassers, casting tundishes, and transport crucibles. All parts are cast, fully dried, and fired in our production facility. This means they are delivered ready to use. With our ‘all-inclusive’ service package, the relining can either be done at the Drache workshop or directly on site at the casthouse. For a complete relining, we use high-efficiency insulation materials alongside our own proven parts. This minimises the heat loss for degassers, deep bed filters, and transport crucibles.
