MOLTEN METAL BATH CHEMISTRY ANALYZER FOR CONTINUOUS HOT-DIP GALVANIZING LINES

THE GALVALIBS 2.0 IS THE ONLY TRUE MULTI-ELEMENT, ONLINE, REAL-TIME AND ACCURATE
BATH COMPOSITION ANALYZER.

Talk to an expert


BATH COMPOSITION ANALYZER ADVANTAGE

Galvanizing is a balancing act of several elements in molten metal bath
composition. Good chemistry management yields higher quality, more valued
products.


MULTI-ELEMENT ANALYZER

The Galvalibs 2.0 is the only online multi-element analyzer for bath management:

 * Effective aluminum
 * Dissolved iron
 * Magnesium level
 * Silicon concentration 

Whatever your process, the Galvalibs 2.0 provides information on all the
elements you need to track. Why limit yourself to one element when you can
benefit from so many more?




PROVEN HIGH ACCURACY

The Galvalibs 2.0 yield real-time concentration measurements with a proven
accuracy of 0.5% (RSD). With the Galvalibs, laboratory-level accuracy is now
available in real time and online. 

Want proof? Take a look at the concentration of dissolved aluminum in the
Galvalibs measurements (blue curve) during a stable run. The scale of the
display is 10 ppm per step. Sensitivity below 2 ppm is clearly seen.

The Galvalibs directly measures the composition of the liquid bath. It doesn’t
require any temperature or phase-diagram-based model for calculation. That’s why
the Galvalibs is the only true high-accuracy bath chemistry analyzer.




DATA YOU CAN TRUST

The Galvalibs 2.0 is an industrial-grade, high-accuracy analyzer, specifically
designed for harsh environments. Its proven stability drift of <1%/month is
unequalled for online LIBS analyzers. What’s more, the quality of the Galvalibs
2.0 data is continuously monitored so you know you can trust it.

To prove it, we’ve collected bath samples every four hours for 25 days and
compared laboratory analysis (circle) with real-time Galvalibs 2.0 measurements
(blue for aluminum and yellow for iron). The match is quite remarkable with no
recalibration during the entire 25-day cycle. Imagine the savings from reduced
bath sampling with Galvalibs’ continuous reliable data.




CONTINUOUS DATA

Production in a continuous galvanizing line never stops, so why rely on discrete
data taken from time to time? Do you really know what’s happening between your
sampling? The Galvalibs 2.0 provides continuous real-time data with no gaps in
information. So you know what’s in your bath, all the time, every time.




MULTIPLE PROCESSES

Agile production is the key to the modern galvanizing line, where quickly
switching production processes is critical. Based on high-precision, laser-based
technology, the Galvalibs 2.0 can switch from galvanized to Zn-Al-Mg to
aluminizing with the touch of a button. The Galvalibs 2.0 is compatible with:

 * Galvanize
 * Galvanneal
 * Galvalume
 * Aluminum-Silicon
 * Zinc-Aluminum-Magnesium




HOW IT WORKS


WHY GALVALIBS 2.0 PROVIDES BETTER INFORMATION THAN A LABORATORY ANALYSIS OF BATH
SAMPLES.

With standard methods of bath chemistry monitoring, a bath sample is taken at a
specific location in the bath at a given time and then analyzed in a laboratory.
Between sampling, the operators have no information about the concentrations and
the ensuing actions to take. Since the Galvalibs 2.0 continuously monitors the
molten metal flowing under the probe, operators benefit from comprehensive
volumetric information about the bath chemistry. The Galvalibs 2.0 measurement
directly conveys the concentration of dissolved elements, so there’s no need to
correct the recorded values for temperature, eliminating error due to inaccurate
temperature readings.


WHAT IS LASER-INDUCED BREAKDOWN SPECTROSCOPY (LIBS)?

Laser-Induced Breakdown Spectroscopy (LIBS) is a laser-based compositional
analysis method of solids or liquid matter. In its basic principle, a
high-energy laser pulse heats a small volume of the target to plasma level. The
light emitted by this plasma is then collected and analyzed by an optical
spectrometer. Since each individual element, such as Al, Fe and Zn, only emits
light at specific optical wavelengths, or colours called optical spectral lines,
isolating and measuring the intensity of selected spectral lines can detect the
presence and concentration of elements in the plasma. The method makes it easy
to measure Al and Fe concentrations in a galvanizing bath.


HOW DOES GALVALIBS 2.0 ACHIEVE ITS HIGH ACCURACY?

The Galvalibs 2.0 LIBS signal is recorded in a controlled, inert environment: a
high-quality Argon bubble. No external contamination can skew the measurement.
In addition, continuous recordings, as many as 1,000, are combined to reject
outliers and reduce noise. This results in higher-accuracy spectral line
intensities and, in turn, the concentration values of each element analyzed.


WHERE SHOULD THE GALVALIBS 2.0 BE INSTALLED FOR BATH CHEMISTRY?

Studies have shown that bath chemistry is fairly well distributed in a standard
galvanizing bath, except near where ingots and steel coils are inserted in the
bath (dross formation). As a result, the Galvalibs 2.0 can be inserted at any
location in the bath, except downstream, in the flow of molten metal from the
feed ingot. With robotic drossing, care must be taken with the robot’s path.
However, the unit is typically inserted in the bath next to the side of the
snout away from the robot's path.


HOW DOES THE GALVALIBS 2.0 DIRECTLY MEASURE THE CONCENTRATION OF DISSOLVED
ELEMENTS?

In its standard operation, the Galvalibs 2.0 probe beam focuses on a small spot
inside a bubble of inert Argon gas, deep within the volume of the molten bath.
This microsampling of the bubble wall vaporizes the liquid phase. The small beam
spot limits the possibility of solid particles (dross) in the probed volume,
yielding a measurement of the dissolved phase only. If a dross particle is
detected in the microsample, a higher-than-normal signal intensity for
intermetallic elements is recorded. With its shot-per-shot signal processing,
the Galvalibs can sort the data and produce reliable, independent solid and
dissolved content measurements.
