Comparison of Thermal Shock Damage and Slag Corrosion

202193 Figure 2 shows the workoffracture WOF results Castable A94 showed a sudden change in load resistance after reaching the maximum load value This represents an unstable crack propagation behavior This behavior is associated with a lower resistance to thermal shock damage The microstructure of castable A94 was not able to distribute the elastic energy

BLAST FURNACE BF REFRACTORY LINING PATTERN

201924 Therefore the appliion condition demands refractory materials which should have high strength low permeability high abrasion resistance and resistance to CO disintegration Superduty fireclay refractory brick or dense alumina brick having Al 2 O 3 around 39 42 can impart these characteristics re quired for stack appliion

Pore evolution and slag resistance of corundum castables

202131 The phase composition was evaluated using the XRD patterns of the refractory castables with 0 06 and 12 nanoZrO 2 addition fired at 1100 °C and 1500 °C As shown in Fig 1a after firing at 1100 °C the sample without nanoZrO 2 contains the corundum and SiO 2 phase while those with nanoZrO 2 added ZrO 2 phases Fig 1b shows that the SiO 2
