Blast Furnace Runner Security Lining
Differential thermal movement of the runner's
steel casing and refractory lining can result
in damage to both components. Subsequent maintenance
and energy costs can prove expensive. Fibres can
eliminate these costs by strengthening the refractory,
preventing spalling and improving thermal insulation.
Recommendation: ME 446
Blast Furnace Runner Cover
Thermal expansion of the steel shell, hot metal
splashes and lifting can crack a plain refractory
lining, resulting in spalling and a reduction
in thermal insulation efficiency. Fibres control
cracking, retain the refractory in place and maximise
shell protection. Thermal efficiency is maintained
and costs are minimised.
Recommendation: ME 446
Main Runner Syphon Box
Hot metal erosion of the box dueling causes
spalled refractory and the loss of flow control
and slag separation. Fibres will reduce spalling,
normally doubling refractory performance.
Recommendation: ME 446
Weirs and Dams
These precast shapes suffer repeated thermal
shock in their short lives. Movement results in
cracking and a reduction in strength. Both refractory
performance and iron quality are reduced. At 3-4%
by weight, fibres can improve performance by 100%
or more.
