So you don’t know what a slab is? No problem. Here you’ll find explanations of the specialized terms and abbreviations from the world of thyssenkrupp Steel Europe.
Equipment and operations used to provide steel products with the desired appearance after forming (straightening, cutting, etc.).
Sheet cut from hot-rolled wide strip, primarily in thicknesses of up to 15 mm (max. 20 mm).
Steel strip wound into a coil.
Further steps for processing flat steel to add greater value, e.g. surface finishing, steel service or joining technology.
Steel produced by melting in an electric arc furnace or induction furnace. The operation method of electric steel furnaces allows the production of chemically resistant types of steel, tool and high-speed steels, specialty steels for mechanical engineering, aerospace and nuclear technology, and magnetic materials.
Flat product in thicknesses from 0.35 to less than 3.00 mm: cold-rolled flat products made of soft or higher-strength grades for cold forming. Primarily metallic or organic coatings.
Modern production line based on thin slab technology for manufacturing hot strips from molten crude steel in just one production step.
Blast furnace sand
Blast furnace slag (granulated) quenched with water and vitreously solidified. Raw material for cement manufacturing.
Blast furnace gas
Interior high pressure remolding
Innovative forming process in which a pressurized liquid is used as an active medium in a closed die. It can be used to manufacture highly complex shapes such as tubular output sections.
Made by cold reduction, this flat product is available in widths of up to 2,000 mm and thicknesses from 0.35 to approx. 4 mm for quality steel. The advantages of cold-rolled strips in comparison with hot-rolled strips include better surface quality, lower tolerances and thinner dimensions.
Steel materials with additional metallic or non-metallic elements (e.g. carbon, chrome, silicon).
A charge supplied to the blast furnace that consists of (1) input materials that contain iron oxide and (2) additives.
Economic, social and ecological goals are considered equally and seen from their networked perspective.
Corrosion protection for high-quality flat steel consisting of metallic (zinc, nickel, aluminum) or organic coatings (paint, plastic).
Bonding agent used between steel and a coating material that adheres poorly or not at all when applied directly to steel. Primers are excellent protective coatings against corrosion and base coats for adding layers of paint later.
Term from DIN EN 10020 – “Definition and classification of grades of steel.” Plain-carbon steels (base steels, unalloyed quality, unalloyed stainless steels) are differentiated from alloyed steels (alloyed quality and alloyed stainless steels).
Quarto reversing mill
A wide range of colors for building with steel developed by color designer Friedrich Ernst v. Garnier. In the meantime, these colors have already been used successfully for many major buildings all over the world.
Unit for melting pig iron from ferrous materials already in the steelworks stream that have not yet been able to be used.
Simultaneous and concurrent engineering
Special structural steels
Steel service center
Supply chain management
Semi-finished parts made from individual sheets with identical or different steel grades, thicknesses or surface finishes, the parts of which are welded together, e.g. laser welding. Tailored blanks can be formed and are customized with regard to special customer requirements.
Ultralight steel auto body. The ULSAB-AVC (Advanced Vehicle Concepts) program is an important element of the continuous efforts of the international steel industry to ensure the future of steel as the material of first choice for automotive manufacturers.
Unit for subsequent treatment of steel under significantly reduced pressure suitable to achieve especially high purity, low gas content and tight alloy tolerances. This allows high quality requirements to be met.
Heat treatment (quenching and tempering)
Heat treatment of heavy plates
Annealing of heavy plates in furnaces to adjust certain microstructures and, as a result, properties that cannot be achieved directly in the rolling process.
- Water or oil hardening and possible tempering
- Normalizing and possible tempering
Hot (wide) strip
Hot strip mill
Magnetically soft steels
The work stored by deformation or another type of energy conversion up to the breakage point.
