一、前言随着各门学科的发展,X射线常温衍射早已不够应用了,必须向着低温和高温领域扩展。X射线高温相机虽早已出现,但它有不可克服的弱点,即不能连续地观测结构随温度的变化,而这一点却正是我们所向往的。高温衍射技术可以对于一个过程进行动态观测,并能观测到物质总体中不同成分或不同相随温度而同时变化的特点,这是其他方法所不能代替的。武钢转炉投产后,我们对转炉渣进行了系统的取样,对物质组成作了分析。发现转炉渣由于冷却速度和状态不同,渣中主相A矿在形态和特性上有差异:缓慢冷却时,渣中A矿多呈板状、条状,容易转变成二次B I. Introduction With the development of various disciplines, X-ray normal temperature diffraction has not enough applications, and must be extended to the field of low temperature and high temperature. Although X-ray high-temperature cameras have long appeared, it has its insurmountable weakness of not being able to continuously observe the changes of the structure with temperature, which is exactly what we aspire to. High-temperature diffraction technology can be a dynamic observation of a process, and can be observed in the material of the total composition of different or different phase with the temperature changes while the characteristics of other methods that can not be replaced. After the WISCO converter was put into operation, we systematically sampled the converter slag and analyzed the material composition. Found that the converter slag due to the different cooling rate and state, the main phase A slag in the morphology and characteristics are different: slow cooling, slag A mostly plate-like, strip, easy to change into a second B
