The permanent development of steel producing technology is a
main driver for the development of new and improved
refractories. The paper briefly discusses the trends in steel
secondary metallurgy and how modern engineered refractories
provide innovative solutions for challenging conditions in the
steel making process. Examples are given how refractories
contribute to steel quality and economical improvements in the
process.
Development of a method to determine the
reoxidation stability of refractories

In many different parts of all steelmaking units, refractory
products are being used and are necessary to protect the
manufacturing facilities against corrosion and to reduce
thermal losses. Particularly, in Al-deoxidized (“Al-killed”)
steel melts, inclusions are formed due to the interaction of
refractory oxides and aluminum that is dissolved in molten

steel. To avoid this, a new method is provided to
characterize refractory products concerning their potential
of reoxidation to Al-deoxidized molten steel melts.

AHSS production with Arvedi ESP: A new door of
opportunity opens
(The article appears in English language)
Bernd Linzer, Axel Rimnac, Sergey Bragin and Bo Yang
(Primetals Technologies, Linz, Austria)
Advanced strength increasing solutions for lightweight construction
as well as other product properties asked for modern material
design – and all at the lowest production costs. With precise
thermo-mechanical rolling and rigorous temperature guidance in
the narrowest possible operational windows, Arvedi ESP opens the
door for the development of new and demanding steel grades in
the shortest possible implementation time and with reduced
alloying expenses. Results are shown from the first ESP line at
Arvedi Steel, Italy and from the five ESP plants recently purchased
by Rizhao Steel, China.
Production of methanol from steel industry process
gases

The increasing electricity from fluctuating renewable energy
sources (RES) leads to excess supply of electricity, causing
curtailment of RES plants. Energy storage, which takes
advantage of resources from the energy sector and industry,

coupled with the production of transportation fuel, offers a
chance to integrate more renewables in the electricity grid and
enable sustainable decarbonisation of mobility. Fuels like
methanol or gasoline from RES-hydrogen or industrial byproduct hydrogen in combination with CO2 from industry have a
lower CO2 footprint and do not compete with food production,
unlike biofuels. This technology offers a new business model to
the industry entering the green fuel market.
Increased productivity of a steel wire pickling line with
integrated high pressure water jet treatment

Bange

Deutsche Edelstahlwerke GmbH, Hagen – both Germany)
The pickling effort for stainless steel wire can be reduced with
integrated high pressure water jet treatment. The normal
procedure consists of several pickling steps of the wire coil.
Residual scale remains on the wire surface especially at contact
points of the wires. In that case a second passage of the coil
through the pickling line is necessary. High pressure water jets
for descaling have been investigated in the presented research
project. Especially scale that is swab removable can be washed
off. The percentage of double pickling is approximately halved
for several ferritic and austenitic steel grades.
Innovation
BSE presents further development of his lance
manipulator: All-in-one-tool increasing flexibility and
efficiency at the electric arc furnace
Andreas Opfermann
(Badische Stahl-Engineering GmbH, Kehl, Germany)
Badische Stahl-Engineering (BSE) has entered a new era of
efficient energy input optimisation in the EAF by upgrading the
lance manipulator with new functions: The existing consumable
lance unit (for injection of oxygen and solids in the refining
phase) and TempSamp unit are complemented by a new jet
burner unit, providing additional power for the melting phase
thus decreasing the electrical energy consumption.
