Elements for roofing and cladding
Components produced from profiled surface-coated steel sheet that are used in the construction
industry as wall and ceiling elements and for exterior cladding.
F
Filler with ring tube vessel
The ring tube vessel receives the beverage from an external unit and distributes it evenly to all bottling
stations. The vessel is made of stainless steel tubing (diameter = approx. 200 mm) which is bent to
form a ring shape.
Flat rolled steel
Flat rolled steel products are manufactured by the hot- and cold-rolling of slabs, including other work
stages, as necessary. The term refers specifically to sheet steel with a thickness of less than 30 mm used
mainly for automobiles and home appliances.
H
Hollows
Seamless tubes used as a input material for the production of seamless precision tubes.
Hot-rolled (wide) strip
Hot-rolled and coiled steel strip used as feedstock for cold rolling or sold as an intermediate product
(e.g. as wide strip).
Hot rolling
Forming process carried out at high temperatures. Different types of rolling mills are used to convert
semi-finished material into hot-rolled strip, plate, sections or seamless tubes.
I
Induction heating/annealing
The term induction heating/annealing denotes the process of passing steel pipes continuously
through several successive inductor coils to heat these to a temperature of 1,200 °C.
L
LD steel
Oxygen steel produced out of pig iron by the Linz-Donawitz process (top blowing process).
P
Pellets
Small spheres manufactured from fine-grain iron ore with the addition of water and binding agents,
hardened in an oven. Pellets are used in the blast furnace along with lump ore and sinter as a source of
iron.
Pickling
Hot strip oxidized (covered in scale) by the hot-rolling process is passed through a bath of hydrochloric
or sulfuric acid. This can either be a continuous (continuous pickling) or discontinuous (pushpull
pickling) process.
