Gas Conditioning: Reduce Gas Temperature
and Volume Prior to Baghouse Entry
A major producer of hot-rolled, cold-rolled and coated
sheets turned to AutoJet ® Technologies for a gas conditioning
system that would:
• Reliably and effectively reduce gas temperature,
humidity and volume to prevent damage to baghouse
filters, ensure efficient baghouse operation and maximize
uptime
• Lower gas temperature without wetting ducts to
ensure maximum air flow and prevent sludge from
forming and creating maintenance problems and
increased disposal costs
The turnkey solution for this particular application
incorporated ten FloMax ® FM-10 air atomizing nozzle
lances monitored and controlled by a Model 2250
AutoJet Spray Controller using closed loop temperature
control. Based on input from multiple temperature
sensors, the system automatically adjusts the liquid
flow to maintain the desired outlet gas temperature.
Independent flow monitoring of each nozzle’s
lance water and air supply ensures peak performance
without interruption.
Marking Defects in Steel Quality
during Quality Checks
Some mills utilize a quality control system that marks
steel defects with color. These systems often use a
digital signal to convey that a defect has been identified.
AutoJet Spray Systems can be integrated with the
quality system to mark the defect with a thin strip of a
colored solution to prevent sub-standard product from
being shipped.
Dispensing Oil at Varying Flow Rates Using a
Zoned Spray Header
If you need to apply different oil products at variable
flow rates, a zoned header system may be just what
you need to ensure precise application of the proper oil.
An AutoJet Spray Controller can monitor and control
the spray process, maintaining the proper flow rate as
line speed varies and ensuring that various strip widths
are accurately coated.
