GAS FIRED BALE OUT FURNACE
GAS FIRED BALE OUT FURNACE
FURNACE DESCRIPTION
Radiation losses from the metal are minimised by the use of a wellinsulated swing aside cover that can cover the crucible when no baling is
needed.
The superb insulation allows for excellent melting performance from the
compact packaged nozzle mix burner.
The advanced insulation materials used in the furnace lining also result in
low casing temperatures, providing comfortable working conditions.
RADIANT PANEL ASSEMBLIES
Twelve high alumina radiant panels surround the crucible and generally
extend to the full depth of the furnace chamber. The self supporting
and interlocking design, provides easy removal, should a panel require
changing These panels efficiently convert gas energy into radiant energy.
HIGH EFFICIENCY
The combination of radiant panels which effectively convert gas
convection to radiant heat transfer and the use of advanced insulating
materials provide a melting and holding furnace of high efficiency with
comfortable working conditions.
FUEL TYPES
The furnace is available for the following gaseous fuels:
SIZE RANGE
Natural Gas:
Propane: Butane: Dynamic Pressure: Note: 9000 kcals/M³
22000 kcals/M³
28000 kcals/M³
20 - 35mbar
Pressures higher than 35mbar will require additional regulation
The MK V Gas Fired Bale Out is available in the size range 85kg - 1327kg
aluminium.
Electrical Supply: 400/415v/480v 3 Phase 50/60hz
Size 1/2 230v 1 Phase 50/60 hz Available
Other crucible patterns than those shown in the table are available to
provide the capacity span indicated for each size reference.

FAILURE PROTECTION
This energy saving and
safety feature enables a
lower holding temperature
to be automatically selected
during periods of non-use.
MOLTEN METAL PRODUCTS
If the metal thermocouple
fails, the feature provides a
programmed level of output
power, rather than switch
the furnace off. Typically set
to 10% the proportioned
burner power is sufficient
to keep the metal within
acceptable temperature
range until exchange can
facilitated.
The control panel’s real time
clock can be programmed to
select reduced temperature
and to return to operational
value when required.
KEY FEATURES
The time clock can also be
set to switch the furnace on
and off at pre-set dates
and times.
ADVANCED DESIGN
The MK V Gas Fired Bale Out Furnace is compact, of robust design and
with the exception of the control panel, has no separate stand alone
components. High reliability is obtained by the use of high quality
components and a purpose designed robust gas burner.
GAS FIRED MkV BALE OUT. GAS BURNER
The furnace is equipped with a high performance, low velocity, fully
proportioning, nozzle mix, packaged burner that conforms to European safety
standard EN746 and other world standards.

The furnace is equipped with
a ‘policeman’ control system
which is designed to prevent
overheating of refractories,
radiant panels and crucible,
thus avoiding a reduction in
life span.
PYROMETRY
A variety of metal temperature
pyrometry can be specified.
This includes floating or fixed
immersion types and for
holding applications, crucible
wall or pocket versions.

Protective circuit breaker, door interlocked
Fully approved, flame failure controller
Programmable time clock
Fully proportional digital temperature controller
Policeman lining protection pyrometry

METAL TEMPERATURE CONTROL
The temperature can be sensed from a floating, fixed or crucible pyrometer.
The dual display programmable digital controller maintains close control, by
regulating the heat input to the burner, relative to actual metal temperature
and set value.
Data based on optimum foundry conditions and practices. For typical
foundry operations a performance factor of 90% of performance ratings
should be assumed.
Data for zinc alloys available on request.
Typical specific energy consumptions: subsequent heat, 1.25kWh/kg. Throughput melting 1kWh/kg *variances subject to crucible pattern
