摘要: 本文叙述在某低碳钢板材夹层所观察到的非金属夹杂物的特征,并对夹层的来源进行了分析。金相检查结合X射线鉴定结果指出矽酸盐夹层与受钢液侵蚀过的粘土耐火材料的矿物组成大致相同,主要为莫来石(3Al_2O_3·2SiO_2)及方石英。根据钢的生产过程,夹杂物的特征及粘土耐火材料受钢液侵蚀后化学成分改变的情况,认为矽酸监夹层的来源可能与钢液中的MnO或MnO·FeO侵蚀粘土耐火材料有关。这种分析并得到了理论的解释。
Abstract:This paper describes the nature of striated inclusions present in certain mildsteel plates,the origin of such inclusions is discussed.Microscopic examinations supplemented by X-ray diffraction studies show thatthe main constituents of the striated inclusions present in the steel plates appearto be the same as found in the attacked layer of fire-clay refractories which predo-minately consist of mullite(3Al_2O_3·2SiO_2)and cristobalite.Taking into accountthe metallurgical history of the plate and change in the chemical compositionof the refractories brought about during teeming,there is reason to believe thatstriated inclusions in steel may be originated from the refractories caused bythe attack of MnO or MnO·FeO present in the liquid steel.
