据德国《国际陶瓷论坛》报道,德国Keller公司制造了带钢板外套的面砖隧道窑,窑长85米,宽3.25米,煅烧温度最高为1150℃,隧道窑外面全部用钢板做的保温外套封闭,外套是由800毫米宽的模数板块组装起来的,自成体系,自己承受重量,接缝处完全密闭,保温隔热效果良好。外套内在煅烧温度最高的部位侧壁装有245毫米厚的陶瓷纤维保温层,窑顶加装470毫米厚的陶瓷纤维保温层,在窑内1150℃
According to the German “International Ceramics Forum” report, the German Keller company manufactured a steel tunnel kiln with a steel jacket, the kiln is 85 meters long, 3.25 meters wide, and the maximum calcining temperature is 1150 degrees Celsius. The outside of the tunnel kiln is completely insulated with a steel plate. The jacket is assembled from an 800-mm-wide modular module that is self-contained. It is self-contained, its seams are completely sealed, and its thermal insulation effect is good. The outer wall of the jacket with the highest calcining temperature is equipped with a 245 mm thick ceramic fiber insulation layer, and a 470 mm thick ceramic fiber insulation layer is installed on the top of the kiln. The temperature is 1150°C in the kiln.
