熔渣纤维化机理研究进展

Research progress on the fiberization mechanism of molten slags

熔融矿渣制备矿渣纤维已成了有效利用资源的新途径,对于冶金熔渣的研究通常分别建立在牛顿流体或非牛顿流体的基础上。然而由于温度等因素的变化,熔渣纤维化过程经历了从牛顿流体向非牛顿流体的转变过程,并且熔渣的这2种状态对于其纤维化都会产生一定的影响。针对冶金熔渣的成纤机理进行了综述,提出将纤维化过程划分为牛顿流体状态与非牛顿流体状态2个阶段的构想,为进一步深入研究熔渣的纤维化机理提供了思路。

The preparation of slag fibre using melt fiberization method has become a new way of effective utilization of resources. The study of molten slag was generally based on the Newtonian fluid or Non-Newtonian fluid respectively. However, because of the change of temperature and other factors, the process of fiberization of molten slag experienced a transition from Newtonian fluid to Non-Newtonian fluid, and both of the two states would have an impact on its process of fiberization. A review was made on the fiberization mechanism of molten slag, a visualize of dividing the process of fiber- ization into Newtonian fluid state and Non-Newtonian fluid state was put forward and the guideline for further research of the fiberization mechanism of molten slag was provided.
