高炉过共晶铁水的热分析定硅

Forecast Silicon in Hypereutectic Molten Iron in Blast Furnace by Thermal Analysis

应用热响应时间短的2型热分析样杯,使过共晶铁水按灰口凝固。通过准确测得共晶反应的最低、最高和结束温度等特征点,来预报其含硅量,预报精度满足实际生产中控制炉外喷粉增硅的精度要求。

Some special temperature points of hypereutectic molten iron in cutectic reaction (for example, the lowest, the highest and the end eute-ectic reaction temperature) can be measured by the short respose time thermal analysis cup, when it solidifies into grey iron. The special points can be used to forecast the silicon. The forecast precision is high enough to guide the increasing in silicon in the blast furnace molten iron.
