Cover
Castables in this application often crack quickly
and spall due to repeated thermal cycling increasing
heat loss, energy consumption and damage to shell
steelwork. A fibre reinforced insulation castable
combines efficient insulation with excellent mechanical
strength, so is better able to reduce maintenance
and energy costs.
Recommendation: ME 430
Lip
Fibres extend the lip's working life whilst reducing
downtime and maintenance costs. A fibre reinforced
lip also helps hold the security and bricked linings
tight so the lining remains safely intact and
in service longer.
Recommendation: ME 446
Security Lining
Without fibres in the security lining, cracking
caused by thermal expansion and mechanical shock
can shorten the effectiveness of the lining thereby
increasing the risk of a hot metal run through.
Fibres remove this and provide a longer ladle
campaign and reduced downtime and maintenance
costs.
Recommendation: ME 446
Impact Pad
Similar to the tundish impact pad, this suffers
repeated thermal shock during its life. ME fibres
at 3-4% by weight, can improve performance considerably,
reduce downtime and cut refractory material and
Installation costs.
Recommendation: ME 446
Porous Plug and Nozzle
A fibre-reinforced plug or nozzle has increased
service life over other designs. Even when cracked
or spalled the refractory is held tight, maintaining
a consistent shape, improving durability and reducing
production costs.
Recommendation: ME 446
Refractory Shroud
Maintaining casting temperature and minimising
oxygen inclusion are vital to steel quality and
production efficiency. A fibre-reinforced refractory
shroud combines excellent insulation with superior
durability in a sometimes vulnerable, crack-prone
refractory shape, keeping production costs to
a minimum.
Recommendation: ME 446
Seating and Well Blocks
Seating and well blocks for teeming ladle
nozzles and porous plugs are expensive consumables.
Since a fibre-reinforced block can often last
as long as the bottom lining, fewer replacements
are needed, so returning important savings in
energy and maintenance costs.
Recommendation: ME 446
