Hot Rolling Steel
Hot Extruding Steel
Cold Drawing Steel
During hot extrusion a round steel billet is pre-heated and, after leaving the furnace, is pushed through a forming die into a profile bar using a ram with an extrusion force of 2,200 t. Hot extruding offers substantial advantages in comparison with hot rolling, forging or machining.
Hot extrusion can be used to make complex steel profile shapes even using metals which are difficult to form. In addition, small lot sizes can be produced economically.
We possesses highly sophisticated CAD and CAM systems which are used to support our customers during the design and engineering phases.
Hot extruded steel profiles offer the benefit of :
|Max. Circumscribed Circle Dia. for Solid and Hollow Profiles [mm]||240|
|Min. Diagonals Dia. for Hollow Profiles [mm]||20|
|Max. Diagonals Dia. for Hollow Profiles [mm]||160|
|Min. Wall Thickness [mm]||4|
|Max. Length [mm]||16800|
|Length||c. 3,000 up to e. 16,800 mm (depending on profile cross-section); with sawn ends, (fixed lengths by agreement)|
|Min. Weight [kg/m]||1.5|
|Max. Weight [kg/m]||100|
|Cross-Sectional Tolerances/ Straightness Tolerances||By agreement, depending on the profile cross- section and material grade; reductions possible, e.g. for functional areas, by agreement|
|Surface||As extruded; descaled or picked on request|
|Materials / Treatments||Nearly all quality and stainless steels in the iron and steel list, special steels, non-ferrous heavy metal alloys|
All required heat treatments are available
