摘要
通过烟道灰与多种覆盖剂的补缩效果和增碳情况对比试验,以及用烟道灰作覆盖剂、作保温套各自单独使用与联合使用时冒口凝固时间和补缩效果的对比试验,证明烟道灰是一种经济效益显著的覆盖剂,为铸造生产合理使用烟道灰提供了参考。
The contrast experiment of feeding efficiency and increasing carbon case given by coal ash out of chimney and various cover agents and the contrast experiment of solidification time of feed head and feeding efficie- ncy indicate that the coal ash is a cover agent which has remarkable economic benefit.These results supply a reference to reasonably using coal ash out of chimney for founding production.
