Shot Peening
Steel or ceramic shot-blasting process for targeted improvement of the surface properties (corrosion
resistance, mechanical strength) of components for high load performance.
Shuttle coater
Technical facility for covering galvanized thin sheet with various coatings.
Slab
An intermediate product produced from crude steel by the continuous casting process and used as an
input material for the production of flat rolled steel.
Surface-coated steel products
Products provided with a metallic or organic surface coating by special processes, for example by galvanizing
or paint-coating.
T
Tailored Blanks
Bonded blanks composed of sheet steel of the varying shapes, qualities and properties, which are
welded together by laser beam. Automobile manufacturers use tailored blanks to produce press parts
for vehicle construction.
Three-roll piercing mill
Hot-forming unit, in which a cylindrical ingot that is heated to hot-forming temperature is forced
through a roll stand (consisting of three driven and calibrated rollers arranged symmetrically on the
circumference) by means of a centered mandrel to form a hollow and stretched block.
Transistor-type welding machine
Machine for longitudinal seam welding of steel tubes based on HF-welding voltage generated by
power transistors.
Tube rounds
An intermediate product manufactured from crude steel by the continuous casting process and used
as an input material for the production of seamless tubes.
Tubes
■ Welded tubes
Tubes made by welding plate or hot-rolled strip. A distinction is drawn between longitudinally
welded tubes (where the weld seam runs along the axis of the tube), and spiral-welded tubes (where
the weld seam spirals around the circumference of the tube).
■ Seamless tubes
Tubes made from tube rounds. After heating, a hollow body is first created by a variety of processes
(including pilgering), which is then rolled and, if necessary, drawn to its final dimensions.
Turn-key plants
Complete plants, facilities and systems ready for operation.
