1994年初,我厂用抵债的一些劣质煤以小于煤矸石的掺配量掺入坯体,焙烧时,火势来得特别快,特别猛,窑内明显过火,砖坯倾斜.采取近打窑门(离焙烧带2个窑室)和揭开焙烧带的火帽放热全无济于事,以后又采用《砖瓦》杂志介绍的“封炉式焙烧法”,窑内上部火度有所下降、但仍不解决问题.在此启发下,我们停止风机运转,停止供氧,同时揭开
At the beginning of 1994, some of the inferior coal used in our factory was blended into the green body with a blending amount less than that of coal gangue. When it was fired, the fire came particularly quickly, especially fiercely. The kiln was overheated and the brick was tilted. The firing of two kiln chambers and the uncovering of the fire caps of the roasting belt are completely useless, and later the “roofing roasting method” introduced in the “brick and tile” magazine has been adopted.
