Applications: RH Degasser
The RH degasser (Ruhrstahl Heraeus process) is used in the production of high-quality steels in secondary metallurgy for degassing the melt.
The RH plant can also be equipped with an oxygen lance (RH-OB) and is therefore ideally suited for the production of deep decarburized and inclusion-free steels (ULC and IF grades).
To degas the melt, the RH degasser is immersed in the liquid steel in the treatment ladle and a partial quantity is sucked into the reaction vessel under vacuum.
To start the treatment 2 immersion tubes, the so-called snorkels, dip into the molten steel, whereupon the vessel is evacuated. Argon or nitrogen is introduced into the inlet snorkel to support the upward movement of the liquid steel. In the vacuum vessel, the molten steel is degassed and decarburized and flows back into the ladle through the outlet snorkel.
The aim of the treatment is to degas the melt, especially to remove hydrogen, in order to reduce the brittleness of the finished steel. RH plants are preferably used in the production of high-quality flat steels.
Alloy chutes and burner blocks are assembled and drilled in the factory and can be delivered to our customers either disassembled or fully assembled.

We supply both ready-for-use prefabricated snorkels, as well as (cut-to-measure) bricks for self-assembly.
In addition to planning the brick installation, our designers also carry out the corresponding steel construction planning. Our steel construction partner carries out the steel construction in compliance with all customer specifications.
