对1823K下轮胎帘线、气门弹簧、超低碳板、轴承钢和硫磺易加工钢中夹杂物、钢和顶渣成分之间的关系进行了热力学研究。在轮胎帘子线和气门弹簧钢的情况下，夹杂物、钢和顶渣之间的平衡在实践中被建立在硅和锰之间。测定了超低碳钢中硅、氧、钙的含量与顶渣成分的关系，并用炉渣中FeTO的作用解释了实践中观察到的较高的氧含量。对轴承钢中尖晶石夹杂物的形成和易切削钢中CaS的析出进行了热力学讨论。
The relations among the compositions of inclusion, steel and top slag were thermodynamically studied at 1823 K in tire cord, valve spring, ultra low carbon sheet, bearing and sulfur free-machining Steels. In case of a tire cord and valve spring steels, the equilibrium among inclusion, steel and top slag was found to be established in practice with respect to Si and Mn. The contents of Si, O and Ca in an ultra low carbon sheet steel were determined as a function of top slag composition, and the higher oxygen contents observed in practice were explained by the effect of FetO in slag. Thermodynamic discussion was made for the formation of spinel inclusions in a bearing steel and the precipitation of CaS in a su If ur free-machining steel.
