通过对垢样以及对浊环水稳定性分析,证明了转炉OG系统结垢主要是水垢,是因浊环水钙硬高造成的。利用帕克拉兹结垢指数(P.S.I.)对现有浊环水水质进行计算,提出了浊环水钙硬控制标准,要防止转炉OG系统结垢,浊环水钙硬必须控制在150mg/L以下。 Through the analysis of scale samples and the stability of turbidity water ring, it is proved that the scale of converter OG system is mainly scale, which is caused by the high calcium content of turbid water ring. The current turbid loop water quality was calculated by using the Parquez Scale Index (PSI), and the standard of turbid loop calcium hardness control was put forward. To prevent scaling of converter OG system, the calcium content of turbid loop water must be controlled below 150mg / L .
