Large rotary kilns use silicon-mullite refractory brick (HXPSS-1450)
1. Definition:
Silicon-mullite brick is a kind of refractory material, which is sintered by the mullite and silicon carbide as main raw materials.
2. Raw material:
Mullite and silicon carbide
3. Product technology:
Sintered technology.
4. Highlight:
1). High strength, abrasion resistant, fine resistant thermal shock stability.
2). Strong Thermal conductivity.
3). Compact structure of the silicon-mullite brick prevents it from corroding of gas and smelt.
4). Not use to break or peel off.
5). Save the fuel.
5. Properties: (see attached table)
6. Application:
Mainly used for constructing the secondary firing zone, transitional zone of the new dry process rotary kilns in the nowadays cement making industry.
