free calcium oxide

The free calcium oxide and the periclase formed in the converter smelting process are primary factor affect the steel slag long-term unstable .

转炉冶炼过程中所形成的游离氧化钙和方镁石是影响钢渣长期不稳定性的主要因素。

Results indicated that the real content of free calcium oxide in the steel slag can be measured by glycol-TG method and its precision was more than 95 % .

因此，乙二醇结合TG法可以测定钢渣中真实的游离氧化钙的含量，准确率在95%以上。

Continuous Determination of Free Calcium Oxide and Magnesium Oxide by Conductometric Method

游离氧化钙、氧化镁连续测定的电导法研究

When pretreated by hot splash method , the slag will contain a great amount of instable large tricalcium silicate particles which are apt to release free calcium oxide , and is therefore unsuitable for direct utilization as a resource ;

热泼法预处理钢渣中含大量不稳定的较大颗粒硅酸三钙相，易析出游离氧化钙，不宜直接资源化利用；

The annual flyash discharge from the Xiaolongtan Thermal Power Plant is about 500,000 t , which has not been utilized properly in construction of dams in Yunnan Province due to high content of free calcium oxide ( fCa0 ) and harmful sulfur trioxide ( S03 ) in it .

开远小龙潭火电厂年排灰量约50×104t。由于粉煤灰中游离氧化钙（fCa0）和有害成份三氧化硫（S03）含量较高，因而在云南的坝工建设中一直得不到利用。
