Specifications
1.Coefficient of thermal conductivity small2.Thermal shock stability is superior
3.Save energy
4.Products shape size accord
?Product introduction:
?1.Products China railway and alkali metal low melting impurity content is very little, high temperature refractory performance is good, can effectively resist the effect of reducing atmosphere
2.Heat insulation brick internal evenly distributed the tiny porosity, blowhole rate is high, the thermal conductivity small, reduce kiln wall heat loss, can effectively save energy
3.Under high temperature, high strength, volume stability, thermal shock resistance stability is superior.
