For energy saving purpose, efforts of reducing heat loss through working lining refractories without deteriorating their service performances are receiving increased importance and attention. Lightening refractory linings by using appropriately micropored sintered material is meaningful in reducing thermal conductivity, releasing structural stress and improving thermal shock resistance, while maintaining other key properties, which is contributive to achieving higher durability while lower heat loss.
The following advantages can be offered by using micropored sintered alumina to partially or completely replace conventional sintered alumina aggregates in refractories:
• Reduced thermal conductivity, contributive to insulating and energy saving
• Reduced material consumption, helpful to lighten refractory linings
• No degradation in strength and resistance to corrosive media attack, due to enhanced grain-matrix bonding.
• Significantly improved thermal shock resistance.
