Utilizing
the latest technology and 100 years of experience, Woodings
provide furnace equipment that delivers long-term reliability
and efficiency.
Above
Burden Probes
Fixed
probe remains in the furnace and allows for continuous temperature
monitoring. The Woodings above burden probe is also capable
of gas sampling, if required.
Features
of this probe include:
• Temperature measuring range of 200° F to 1800°F
• Removable tray for thermocouple changing
• Cooling by water, steam or nitrogen
• Fixed probe remains in furnace

Top
Charging Chutes
Woodings produces and rebuilds top charging chutes using stainless
steel construction with chromium carbide overlaid liner plates
with rock box options. |
Feeder
Spouts for Top Charging Equipment
Feature chromium carbide overlay liners.
Bells
and Hoppers
Whether
you need small or large, one-piece or two-piece hoppers, Woodings
delivers. We collaborate with our technology partner, Franz
Grabe, to produce bells that use Grabe overlay plate. Grabe
utilizes technology that allows the weld overlay to be welded
to a flat plate and then fabricated into the unit for better
weld penetration and greater structural reliability.
The
bell top can be cast or fabricated with machined or ground seat
surfaces and chromium carbide overlay on burden and seat area.
An
optional stepped seat design is available on bells to reduce
seat surface wear.
In-Burden
Probes
The probe is electro-mechanically driven, and takes gas samples
at regular positions from the furnace center to the furnace
wall, at a nominal level below the maximum fill level. The probe
lance may be water-cooled for heat protection.
Bleeder
Valves
We manufacture and recondition bleeder valves designed for long-lasting
service.
Bleeder valves up to 31" diameter are available, and
are normally operated from the furnace top hydraulic
system. A manual override can be incorporated to allow
for emergency operation from a lower level. Also available:
a non-hydraulic counterweighted style valve that opens
from the pressure overcoming the counterweights.
The
opening mechanism is a Siemens VAI patented design, actuated by
hydraulic cylinder, and featuring an over-center spring assembly,
providing automatic pressure relief. Once open, the valve lid
is positioned out of the gas flow.
The
bleeder valves utilize both metal-to-metal and secondary
soft-seating, designed for quick and easy replacement.
Equalizing
and Relief Valves
Woodings E&R valves are available as plug or flap types,
operated hydraulically or pneumatically. Woodings/Siemens VAI offers
a variety of E&R valves that can provide significant cost
and efficiency benefits.
In
a unique design and engineering breakthrough, the Woodings/Siemens VAI alliance has led to the development of an integrated manhole
access door into the 16” flap valve. Maintenance time
and cost are slashed, and efficiency increases dramatically.
Lock
Hoppers
Available
in conical or flat shapes, Woodings’ lock hoppers feature
chromium carbide plates or casting.
Stockline
Ignition Lance
Used
during maintenance operations on the furnace top, this lance
is used to ignite the gases given off by the burden, and then
maintain combustion. Constructed of stainless steel, the lance
features:
• Quick release manhole for furnace entry
• Electric motor with gearbox or air motor with gearbox
used for lance travel
• Emergency hand drive
• Lance ignition using coke oven, or natural gas
• Stand alone control panel
• Lance constructed of stainless steel
Stockline
Detector
Directly
connected to furnace charging control system, this detector
is a self-contained gas tight unit with electric motor drive.
Features include:
• Standard gearbox
• Easily replaceable weight
• Emergency handwheel operation
• Cam switch unit for accurate positioning
The level detector continually measures the amount of bulk material
inside hoppers and silos to determine when materials need to
be replenished. The product’s major benefit is its ability
to improve both the timing and quantity of material additions.
The precise feedback of the Matsushima level detector ensures
that the right amount of material is added only when it is needed.
The risk of overloading the hopper or silo, or adding too little
material, is significantly reduced if not eliminated.
Radar
Stockline Indicators
For level measurement in severe environments where high density
dust exists at high temperature and high pressure, a radar
level indicator gets the job done. This indicator utilizes radar
measurement technology for continuous,
non-contact measurement.
This is an easy-to-install indicator and it is virtually maintenance-free.
Seal
Valves
Woodings can repair of seal valve operators to ensure zero leakage
at the shaft seals.
We utilize a special test box to ensure no shaft seal leakage
prior to shipment.
Throat
Armor Plates
Available with movable or fixed armor. Movable armor drive systems
may also be specified. Armor plates can be chromium carbide
overlaid plate or castings.
