In the field of aluminium melting, LOI is specialized in scrap melting with minor melting loss and is worldwide very successful with the third generation of twin-chamber melting furnaces. The latest developments for process guidance contribute to an increased metal yield together with lower emissions.
Regarding the aluminium heat treatment plants, LOI focuses on plant flexibility for various automotive components and highest cooling rates that are also applicable to special alloys. To ensure the proper cooling rate for each material, the plant design follows the analysis of decisive criteria.
In the steel area, LOI has extended the product range for steel heat treatment to both extremely thick and thin plates.
The automatic creation of recipes is indispensable for the heat treatment of various types of railway wheels. Highly complex quenching facilities ensure a uniform finepearlitic structure down to a depth of 45 mm. In the heating sector, LOI offers numerous plants for forges and rolling mills. An adjusted process guidance allows the low decarburization heat treatment of carbonaceous materials.
The product range of LOI includes plants for both nongrain oriented (NGO) and grain-oriented (GO) electrical sheets. In the area of continuous heat treatment, the furnace plants comprise annealing-pickling lines (APLs for NGO and GO), decarburization lines (DCLs for GO), final coating lines (FCLs for GO), annealing and coating lines (ACLs for NGO) as well as high-temperature batch annealing furnaces for annealing temperatures > 1,250 °C (MBAF for GO).
For the heat treatment of tubes, rods and wire, LOI supplies tailor-made solutions for the continuous heat treatment in roller hearth furnaces as well as for the batch-wise heat treatment in bell-type annealing furnace plants. Protective gas atmospheres such as 100 % N2 to 100 % H2 as well as process-controlled reaction gases (e. g. endogas) can be used.
In the area of heat treatment of steel strips, the fully automatic crane operation in LOI‘s unique HPH bell-type annealing plants ensure high production output with lowest consumptions.

Industriepolitik 2026: „Raus aus dem Jammertal, rauf auf den Lösungsweg“
Der Wirtschaftsverband Stahl- und Metallverarbeitung (WSM) fordert konkrete Sofortmaßnahmen zur Stärkung der Wettbewerbsfähigkeit: Aussetzung des nationalen CO2-Preises für die Industrie und Abschaffung des Solidaritätszuschlags. „Wir müssen raus aus dem Jammertal, rauf auf den Lösungsweg”, betont WSM-Hauptgeschäftsführer Christian Vietmeyer. Beide Maßnahmen seien kurzfristig umsetzbar und würden 2026 direkt wirken.
