Chemical pickling line for hot rolled steel strip
1500 x 6 mm
BKM Bolender Maschinenkonstruktion GmbH
output of about 250,000 tons of hot rolled strip.
Unlike other lines, this line is of extremely compact design.
The resulting is saving of footprint area and energy cuts
operating costs substantially. The units are set up in and on
a concrete foundation with appropriate isolation. The tanks,
heat exchangers and piping with acid of about 80
centigrade are located in closed, isolated spaces beneath
the pickling pits. This design keeps heat of loss as low as
possible.
After pickling the strip is dried and the edges can be
trimmed. In addition to optional passivation, exactly metered
quantities of oil can be applied to the strip surface.
