Burners for annealing and galvanising lines
to recover waste process gases
INDUSTRIAL engineering group
Fives has developed a wide range of
AdvanTek® WRT burners for annealing
and galvanising lines to reduce
pollutant emissions and improve
energy efficiency.
AdvanTek burners are a proprietary
technology of Fives, designed for both
reheating and processing line furnaces.
The burners, equipped with combustion
systems, operate with different fuel
types, including coke oven gas, natural
gas, mixed gas, LPG, heavy fuel oil and
domestic fuel oil.
The new AdvanTek WRT 2.0 burners
use basic oxygen furnace (BOF) gas,
which is a low heating value gas mainly
composed of CO (LHV 7,100 kJ/Nm3).
A number of tests, conducted at Fives’
Bar-Le-Duc test centre in France,
demonstrated an optimum combustion
efficiency, with 71 per cent efficiency for
BOF gas with NOx less than 50mg/Nm 3
at 3% O2. the combustion efficiency
could reach 76 per cent with natural gas.
AdvanTek WRT 2.0 burners are
available for a power range of 100 to
180kW (7" and 8" W-shape radiant
tubes), and can be installed in new or
existing annealing and galvanising lines.

Force detection in straightening
CaRtaCCi’s fifty years of history have
been marked by the production of
straightening machines equipped with
advanced technological solutions, able
to meet the quality standards required
by different market sectors.
The automotive and oil and gas
industries in particular have determined
an increasing adoption of ten-roll
machines, able to control within close
tolerances parameters including
linearity on the body and at the ends
of tubes; ovality around the nominal
diameter; the absence of marks on
the body or the ends of tubes; and
complete surface coverage of the
tube with consequent uniformity of the
mechanical characteristics for each
section of the tube.
In response to growing demand
from customers operating in areas
where quality standards are particularly
high, Cartacci has developed a new
technology that aims to provide the
operator with a range of important
information about the way in which the
machine is working on the tube in the
process.
This technology, called FDT (force
detection technology) allows the display
on the touchscreen of the applied
efforts for each pair of rolls, on the tube
in process, so that the operator has a
greater awareness of the effects that
the adopted setting may have on the
product in qualitative terms.
The technology is aimed at increasing
both the quality of the product and
the proficiency of the operator, who is
provided with a means of having greater
control of the process.
FDT is based on the use of a
sophisticated system that allows
results to be achieved, maintaining the
complete rigidity of the machine (the
total absence of any mechanical play),
which is fundamental to ensure the
requested tolerances.
The adoption of mechanical systems,
such as loading cells, based on a
minimum vertical movement, implies
the loss of this characteristic. By using
a hydraulic solution, FDT instead allows
absolutely rigidity without compromising
the principle working of the straightening
machine.
