铸铁变质的冶金物化条件是当前铸铁理论和生产实际问题的交点。本文在发展了检 测铁水中活性氧、硫含量方法的基础上，定量研究了氧和硫的反球化作用、铸铁球化和 孕育的冶金物化条件及其相互关系、探讨了球化元素和反球化元素对球化和蠕化条件的 影响规律，由此找到了一种研制变质剂的高效判据，并用来具体考察稀土镁铝蠕化剂的 特性，最后根据实验得到的活性氧量与铁水球化程度的对应规律发展了一种新的炉前快 速检测球化率或蠕化率的方法——氧电势法。
Metallurgical materialization of the deterioration of cast iron is the current cast iron theory and production of the actual point of intersection. Based on the development of the method for detecting active oxygen and sulfur in hot metal, the quantitative analysis of the anti-spheroidization of oxygen and sulfur, the metallurgical physical and chemical conditions of cast iron spheroidization and inoculation, Balling elements on the rules of the ball and the conditions of the vermiculite, thus finding a high criterion for the development of modifiers, and used to specifically investigate the characteristics of rare earth Mg-Mg vermiculite, and finally according to the experimental results of reactive oxygen species and Corresponding law of the degree of hot metal spheroidization developed a new method to quickly detect the spheroidizing rate or the rate of melting in front of the furnace - oxygen potential method.
