1外火弱、进度慢外火弱,进度慢,是轮窑生产中普遍存在的现象。只有通过码窑、焙烧、用风闸3个方面的操作,来加速和加强外火,从而达到火候一致,火锋平齐,减少外燃煤和内燃炭,提高砖瓦的质量才是有效的措施。1.1在码窑方面装窑时,根据内燃料大小,决定窑外部砖坯码窑的稀密程度,并 1 outside the fire is weak, slow progress outside the fire weak, slow progress, is a common phenomenon in the production of round kilns. Only through the kiln, roasting, wind gate with three aspects of operation, to accelerate and strengthen the outer fire, so as to achieve the same heat, the front flush, reduce the external combustion of coal and internal combustion, improve the quality of the tile is effective Measures. 1.1 kiln in the loading kiln, according to the size of the fuel, to determine the kiln brick kiln external density, and
