项目摘要
Fundamental Kinetic Study of Slag Metal Gas ReactionsThe current project will determine fundamental properties important in metal refining. In particular, properties that can be used in mathematical models to help optimize steelmaking processes. The work will impact practical steelmaking and the scientific community. The data will also be useful in the design of carbon free electrochemical steelmaking processes.Metallurgical slag is seen by the lay-person as a waste from the process and is considered unsightly and undesirable. However to the metallurgist it is an important reagent used to refine the metal. This is particularly true in steelmaking where slag is used to remove sulphur, phosphorus and other elements, from the metal. Slag may also supply oxygen to the metal which in the case of desulphurization is a bad thing but in the case of dephosphorisation is good. The balance between the rate of oxygen supply from the slag and consumption by reactive elements in the metal is important in setting the so called "dynamic oxygen potential" at the slag/metal interface. It is not possible to measure the dynamic oxygen potential and in most cases it cannot be calculated directly. In our laboratory we have recently proposed method by which it can be determined but, without more information on the rate of oxygen transfer, we still do not have a comprehensive picture.The proposed research is intended to measure transfer rates of oxygen for a wide range of slags and conditions and to compare these with measurements of electronic conductivity(also known to assist oxygen transfer). These measurements combined with measurements of oxygen transfer by the method recently employed in our lab, will offer us the ability to create better models of processes.The conductivity measurements are also important for our fundamental understanding. A mechanism for electronic conduction was identified in our lab for slags containing iron oxide. This mechanism, known as diffusion assisted hopping, was recently shown by workers in my lab to work for slags containing manganese. The current research will investigate whether this mechanism works for a range of different slag types.
渣-金属-气体反应的基本动力学研究本项目将确定金属精炼中重要的基本性质。特别是,可以用于数学模型的属性,以帮助优化炼钢工艺。这项工作将影响实际的炼钢和科学界。这些数据在无碳电化学炼钢工艺的设计中也将是有用的。冶金炉渣被外行人看作是工艺中的废物,并且被认为是难看的和不受欢迎的。然而,对于专家来说,它是一种用于精炼金属的重要试剂。这在炼钢中尤其如此,其中炉渣用于从金属中去除硫、磷和其他元素。炉渣还可以向金属提供氧,这在脱硫的情况下是坏事,但在脱磷的情况下是好事。从炉渣供应氧的速率与金属中活性元素的消耗之间的平衡对于设定炉渣/金属界面处的所谓“动态氧势”是重要的。不可能测量动态氧势,并且在大多数情况下无法直接计算。在我们的实验室中,我们最近提出了一种可以确定氧转移速率的方法,但由于没有有关氧转移速率的更多信息,我们仍然没有全面的了解。拟议的研究旨在测量各种炉渣和条件下的氧转移速率,并将其与电子电导率(也已知有助于氧转移)的测量结果进行比较。 这些测量与我们实验室最近采用的氧传递测量方法相结合,将为我们提供创建更好的过程模型的能力。电导率测量对于我们的基本理解也很重要。在我们的实验室中,发现了含氧化铁渣的电子传导机制。这种机制,被称为扩散辅助跳跃,最近被我实验室的工作人员证明适用于含锰炉渣。目前的研究将调查这种机制是否适用于一系列不同的炉渣类型。
