干熄焦除尘灰作铁水保温剂的试验研究
|
摘要
文章通过干熄焦除尘灰的制块试验、保温性能测定试验和工业应用试验,综合分析了干熄焦除尘灰作铁水保温剂的性能和应用后对铁水[S]的影响。结果表明,干熄焦除尘灰作铁水保温剂时其保温性能与碳化稻壳相当,高于复合保温剂,同时对铁水[S]无明显影响,在产品质量稳定性上具有明显优势,应用前景广阔。
In the paper, on the basis of system of CDQ dust block test, heat preservation performance test and industrial application test, the performance of CDQ dust as heat preservation agent of molten iron and impact of [S] in iron were comprehensive analyzed. The results show that the heat preservation performance of the CDQ dust as molten iron is equivalent to carbonized rice husk, and which is higher than the composite insulation agent, and has no obvious effect on the [S] of molten steel. So the CDQ dust has obvious advantages on stable product quality, and have broad application prospect.
