Longer running times and shorter down-times for repairs or new linings mean that specific solutions are more and more frequently required for the refractory lining of blast furnace runners. This is why we provide concepts tailored to suit the requirements of any particular section of runner and to take account of latest developments.

Special solutions for the refractory lining
of blast furnace channel systems
Longer running times and
shorter down-times for repairs
or new linings mean that specific
solutions are more and more
frequently required for the
refractory lining of blast furnace
runners. As a ­consequence, a
balanced ratio of SiC to carbon is
just as important in a successful
material as selection of the right
type of bond or the type of lining.
This is why Refratechnik Steel
provides concepts tailored to suit
the requirements of any particular
section of runner and to take
account of latest developments.
Whether the product involved
is rapidly heatable Hydrobond
castable, non-cement-bonded
Nanobond jetcast concrete
for hot repairs or high-quality
synthetic raw materials developed
in-house – Refratechnik is always
taking innovative and highly
successful technical and economic
approaches.
Our range of castables, gunning
mixes, granulates for ramming,
products for jetcasting and pre-
shaped blocks mean we know
the solutions our customers need.
