高铝.粘土轻质保温砖（GB3994-83.GB-3995-83）
High alumina insulating refractory bricks and fireclay insulating refractory bricks
　　本产品结构均匀、闭口气孔多、隔热性能好、导热系数低、强度高，在使用中能保持炉温均衡。减少散热损失，适用于各种工业窑炉及热工设备上的隔热层、保温层。
　　There products have homogeneous structure,lots of closed pore,good themal msulating property ,low thermal conductivity and high stength,When in use ,they can keep temperature of furnaces in balance ,decrease the heatloss.So they are applied to heat insulating linings of kilns and heat cquipment.
