In the face of stiff competition, the steel and iron industries are subject to
strict regulatory controls. Various Linde solutions can also help to harmonize
productivity and cost targets with environmental pressures, whether production
is based on ore or scrap.

Proprietary technology from the Linde Metallurgy group includes: 1) Customized
blast furnace solutions for oxygen use in heating stoves, 2) new OXYGON® systems
for proven efficiency gains during preheating of ladles, and 3) REBOX®technical
solutions that can increase production capacity, improve yield, cut energy
costs, and reduce emissions in existing or new reheat furnaces.

At AISTech 2013, Linde and MST (South Lyon, MI) documented a 50% reduction in
cycle time for reheating 4-3/4″ billets in a rotary hearth furnace, and a 63%
reduction in energy consumption using the REBOX® technology.

Linde is also a leading supplier of technologies such as process gas heaters,
steam methane reformers, pressure swing absorption units, and carbon dioxide
purification units used in natural gas-based DRI plants – growing in importance
in the U.S. with the increased production and reduced cost of natural gas.1
Linde also markets carbon dioxide that may be captured and purified from certain
DRI plant configurations.

Oxyfuel Technology Pioneer
Over the past few years, Linde REBOX® technologies have become the premier
method for enhancing steel reheat furnace operations. The REBOX® portfolio
includes equipment and control systems for oxygen-enrichment, oxygen-lancing,
oxyfuel-boosting and 100 percent oxyfuel operation in reheat furnaces and
annealing lines. Linde develops and applies REBOX® technical solutions that meet
the specific needs and conditions for each case.

Linde has been a pioneer in oxyfuel solutions for reheat furnaces since the
1990s and has performed more than 130 installations around the globe. In
addition to more efficient energy input and increased heating rate, the
precision technology offers significant environmental and maintenance
advantages, including reduced scaling, and minimization of NOx formation and
total flue gas emissions. In conjunction with MORE S.r.l., Linde also offers
cost-saving oxyfuel and process optimization solutions for electric arc furnaces
(EAFs) to produce liquid steel in a safe and cost-effective manner.

Linde, a leading global industrial gases company, provides industry-leading
portfolio solutions for the ferrous and non-ferrous metallurgy industries,
ranging from gases and equipment to process consulting and services. For more
