silicon carbide refractory beam
It has the the futher of good thermal conductivity,
good high temperature strength,
wear resistant and erosion resistant,
and good thermal shock resistance.
And it is widely applied in lining non-ferrous metal smelting; calcining-endure board,pushing board,and saggar of industrial ceramics;muffle boot of furnace; lining and ignitor of CFBB;lining and ignitor of CFBB; lining if garbage incinerates,etc.
