  • Aluminium

    Aluminium is a silvery-white light metal which is the third most abundant element and the most abundant metal. In 2010 alone, 41 million tonnes of primary aluminium was produced. Although aluminium is very ignoble, it reacts only superficially with air and water at room temperature due to passivation.

    Aluminium is a chemical element that has the element symbol Al and the atomic number of 13. Aluminium belongs to the third main group in the periodic system and to the thirteenth IUPAC group, the boron group, which used to be grouped with the earth metals.

  • Annealing

    Our services in the field of annealing include pre-heating machine components prior to welding, post heat treatments following welding and metal-forming processes, stress-relief annealing, soft annealing and normalisation as well as specialised annealing and homogenising of aluminium ingots.

  • Annealing facility

    Products that are processed in an annealing facility include steel containers, steel constructions, welded parts, cast pieces, forged pieces, machine parts and aluminium blocks.

    Various types of heat treating are used to improve the properties of materials. These include stress-relief annealing, homogenisation annealing, soft annealing, normalising, coarse-grain annealing, recrystallisation annealing and tempering with exposure to air.

  • Annealing furnaces

    Annealing furnaces are used for heat treating various components and materials. Examples include processing steel containers, steel constructions, welded parts, cast pieces, forged pieces, machine parts and aluminium blocks. Parts for wind turbine generators are also processed by DEBUS Glühen - Wärmebehandlung - Sandstrahlen GmbH located in Siegen-Wittgenstein county.

  • Heat treating

    According to DIN EN, heat treating is a technique or a combination of various techniques for treating components. Components are subjected to changes in temperature or temperature cycles during which certain material characteristics are addressed and modified.

    With the heat treating technique at DEBUS, material characteristics such as strength, temperature stability, surface hardness and ductility are improved by temperature changes. This enables treated components to be made significantly more durable.

  • Homogenising aluminium rolling ingots

    The DEBUS Glühen - Wärmebehandlung - Sandstrahlen GmbH furnaces are also used for homogenising and relaxing aluminium rolling ingots – especially for processing particularly hard alloys notably for the aerospace sector.

    Tension generated when the material is poured and while it is cooling is reduced by heat treating. This is what makes further mechanical processing possible. Homogenising furnaces are usually heated using gas.

  • Normalising

    Normalising is usually carried out after components have undergone hot forming. Using normalising, it is possible to attain a fine-grained Ferrit/Perlit microstructure.

  • Normalising

    Normalising is used to attain a consistent microstructure in materials. It is used to eliminate irregular and coarse microstructures.

     

  • Sandblasting

    Sandblasting or abrasive blasting is a technique in which the surface of a material or component is treated by exposing it to sand. This acts as an abrasive agent against dirt, rust, paint and other impurities.
    For this, a compressor generates a strong, even stream of air which takes the blasting agent (e.g. sand or even blast furnace slag, glass granules, corundum, steel, plastic granules or soda in various degrees of coarseness) from a holding container and propels it onto the surface. The abrasive agent is applied to the treated surface at high speeds. The abrasive effect of the blasting agent loosens unwanted substances or impurities from the surface.

  • Soft annealing

    Soft annealing is a thermal process which is used to make materials more easy to shape and to reduce their hardness. In this process, the material is annealed at a temperature only slightly below its transformation point and subsequently cooled down slowly.

  • Stress-relief annealing

    Some materials have residual stress which can change the dimensions and the shape of the component, increase its sensitivity to cracks and impair its fatigue strength. In order to prevent this, the stress-relief annealing technique is used.
