冶金过程与非平衡态热力学

Metallurgical processes and non-equilibriumthermodynamics

以纯净钢 (超低碳钢和超低硫钢 )的真空循环 (RH)精炼为例 ,说明了冶金过程的非线性和非平衡性特征 ,分析了冶金反应工程学和非平衡态热力学的异同 ,讨论了基于非平衡态热力学和冶金反应工程学的观点、原理和方法研究和处理实际冶金过程的必要性和可行性 指出 :为真实地定量描述实际冶金过程 ,必须充分考虑其非平衡性和非线性的特点 ;非平衡态热力学在冶金领域应该和能够发挥其作用 ,应该加强。

Taking the vacuum circulation (RH) refining of clean steel (ultralow carbon and ultralow sulphur steel) as an example,the non linear and non equilibrium features of metallurgical processes have been illustrated.The similarities and differences between metallurgical reaction engineering and non equilibrium thermodynamics have been analyzed.The necessity and feasibility investigating and dealing with practical metallurgical processes from the viewpoints,fundamentals and methods of non equilibrium thermodynamics with metallurgical reaction engineering have been discussed.It is pointed out that non equilibrium thermodynamics should and can play its role in the metallurgical area,and the studies on non equilibrium thermodynamics of metallurgical processes and its applications should be enhanced,and accelerated to progress and development.
