ng>Characteristicng>:

1 Lower content in iron, alkaline and impurities, goodhigh temperature properties, energy good resistance to reduction atmosphere.

2 Homogeneous structure, light weight, high crushingstrength, good insulating properties, energy saving because lower heat storagein the furnace body during cooling-heating cycles.

3 High strength, good volume stability and thermal shockresistance under high temperature.

4 Less size tolerance due to grinding and shaping aftersintering, this meets the requirement of construction.
ng>Applicationng>: used inmetallurgical industry for hot galvanizing furnaces, silicon steel treatmentfurnace, hot blast stoves and in petrochemicals industry for ethylene crackingfurnaces, hydrogen making furnaces, one-stage conversion furnaces, Sulfurrecovery devices, and also in other heat engineering equipment such as rollingkilns, shuttle kilns, anti-nit riding and ant carbonizing furnace.
