优质硅砖系列制品
玻璃窑用硅砖采用高纯硅石和符合矿化剂为原料，经合理的颗粒级配、压制、烧制而成。该产
品具有SiO2含量高，熔融指数（AL2O3+2R2O）低、Fe2O3含量少，荷重软化点高、真密度小、
低含量残余石英、方、磷石英含量高等特性。产品外形规整，尺寸精度高。可满足各种外形不
加工，直接砌筑的要求。广泛用于玻璃窑的大碹、蓄热室及投料口前脸墙等部位。
焦炭窑炉用硅砖适用于国内、外大型焦炭窑炉。
 
Silica brick for glass furnaces is made of high purity quartzite and compound
mineralizer with perfect grain size distribution,pressed and sintered.It has high
SiO2,low flux (AL2O3+2R2O),low Fe2O3,high refractoriness under load, low true
density,low residual quartz,high tridymite and cristobalite.It could be directly
laid without polishing because of uniform configuration and precise
measurement.This product is widely used in glass kiln vault,recuperator arch,face
wall of charging hopper etc.
