硅莫红砖、低导热硅莫红砖
GMH bricks、Low thermal conductivity GMH bricks
硅莫红砖 是采用高品质铝矾土熟料、高品位碳化硅、红柱石以及复合添加剂经高压成型、高温烧结而成。产品的主要特点有;抗热震性能优良,荷重软化温度高,耐压强度高,耐磨性好以及对碱盐物料的抗侵蚀和抗渗透能力强。产品适用干大中型水泥回转窑过渡带。
低导热硅莫红砖 是在硅莫红砖的基础上加入轻质保温层和隔热纤维层,从而大幅降低了产品的整体导热系数,使筒体温度明显降低50~100℃。
GMH bricks is made of high quality bauxite clinker,high grade silicon carbide,andalusite and compound additive by high pressure molding anc high temperature sintering.The main features of the product are:excellent thermal shock resistance,high softening temperature under load. high compressive strength, good wear resistance and strong anti-erosion and anti-penetration ability of alkali and salt materials. The product is suitable for transition zone of medium and large cement rotary kiln.The low thermal conductivity of silamonium brick is added on the basis of the silamonium brick light insulation laver and heat insulation fiber laver, so as to greatly reduce the overall thermal conductivity of the productso that the temperature of the cylinder is sianificantly reduced by50~100℃.
