The usual problems encountered are those of thermal shock and
slag formation. A coating of Nonvit at 2 to 3 mm minimises the life of
the refreactory lining.
The refractory lining is typically a high alumina castable which is
subject to the destructive effects of high temperature and molten
aluminium. The frequency of repairs is reduced by a lining of
3 to 6 mm Non-Vit.
3 mm of Nonvit will seal the refractory against the leaching effects of
molten aluminium. 6mm is used to line the connencting channel.
This part of the boiler is subjected to both hugh tempretures and
slag attack from the products of combustion. A coating of 2 to 3 mm
of Non-Vit on the refractory sirface will minimise the effects of
spalling, slagging and abrasion.
Non-Vit is used for patching cracks, crevics and joints on the crown.
It may be applied by trowelling, ramming, tamping, pouring or
caulking.
A coating of 2 to 3 mm Furnascote Nonvit applied to the refractory
surface increases it resistance to the destructive effects of spalling,
slagging, chemical attack and erosion.
Induction Furnace
Receivers
Crucible Furnace
Tunnel Kilns
Small Ladles
Reheating Furnace
The rammed lining is subjected to chemical attack by molten metal
and to cracking and spalling from thermal shock, 1 - 3 mm of
Furnascote Nonvit will reduce these effects, extend the life of the
furnace and improve the quality of the processed metal.
A thin coat of 1 to 2 mm Nonvit reduces the adhesion of slags to the
floor. The Nonvit makes it easier to remove slag when cleaning.
A coating of 2 to 3 mm Furnascote Nonvit on the walls and lips of
receivers will prolong the life of the lining.
Hand ladles lined with mouldable refractory can be coated with 2 to
3 mm Nonvit to increase the number of heats and increase
production life
Frequent repairs are necessary due to the damaging effects of high
temperature and thermal shock. These conditions cause cracking of
the refractory lining and heat losses. Nonvit coated at 2 to 3mm ,
will eliminate or minimise the problem.
Thermal shock and slag formation are common problems with high
refractory wear around burner ports. Salt glazes are corrosive to
conventional refractories. A coating of Furnascote Nonvit at 2 to 3
mm mininises the destructive effects of combustion, glazing and
thermal shock. Slag removal is easier and reject rates reduced.
Tundish In Continuous
Casting
Electric Arc Furnace
Frequent repairs and shutdowns are encountered due to the effects
of high temperature and thermal shock. A thin coat of 2 to 3 mm
Nonvit prolongs the life of the refractory lining.
High temperature and thermal shock lead to spalling of the
refractory lining. These effects and hence the cost of maintenance
can be reduced by application of 2 to 3 mm Nonvit.
The centre section of the roof is made of either castable or plastic
refractory. A coating of 2 to 3 mm of Nonvit will minimise the
destructive effect of high temperature and thermal shock, prolonging
the life of the refractory.
A thin coat of 1 to 2 mm of Nonvit on the baffles prevents or
minimises the effects of spalling, reduces the adhesion of slag and
ensures a gas tight surface.
The burner throat is subjected to intense wear and tear due to the
effects of high temperature, slagging, chemical attack, erosion and
thermal shock. A coating of 2 to 3 mm of Nonvit resists these
combined effects on the refractory lining. A coating of 1 to 2 mm on
the walls and floors minimises the adhesion of slags and helps in
prolonging the life of the refractory life.
High temperature, thermal shock, slags, chemical attack and
erosion have a devastating effect on the parts exposed to heat,
particularly the burner throat. A 2 to 3 mm coating of Furnascote
Nonvit on the burner throat and a 1 to 2 mm coating the rear and
front baffles will extend the life of the refractory lining.
