Feature
1.High mechanical strength,
2.Good thermal shock resistance,
3.High refractoriness under load,
4.Tiny linear variation,no cracking,
5.Resistant to scour and erosion,abrasion,
6.Good slag resistance,
7.Good volume stability under high temperature,
8.Easy to operate: times and labor saving.
Application
Mullite refractory castable is the ideal product for the high temperature parts of cement kiln such as cement kiln cooler, front mouth and the lining of high temperature furnace such as electric furnace,LF furnace, catalytic cracking reactor of petrochemical industry.
