ABSTRACT With a Ni-base single crystal superalloy, DD8, a series of SC samples solidified with various solid-liquid interface morphologies planar, cellular, dendritical cellular, coarsely dendritic and fine dendritic ctc.

选用镍基单晶高温合金DD8为研究对象，利用籽晶法控制单晶的三维晶体取向，在自制高温高梯度LMC定向凝固装置上制取不同界面形态的单晶试样，首次系。。。

Critical C/Fe ratio as a new concept has been put forward in this paper, when the amount of carbon adding into pellet large than critical C/Fe ratio, it will results that the S% of DRI goes beyond the criterion so that EAF refuse to use it, when less than critical C/Fe ratio, it will accelerate reduction and desulphur.

文章根据热态DRI的再氧化机理，提出了一种利用半熔融密封料覆盖反应罐口的防再氧化理论，在还原温度时半熔融密封料熔化成液相，将罐口密封，反应罐冷却时，这层半熔融密封料凝固并和罐壁紧密结合，阻止氧化性气体的侵入，达到防氧化的目的。
