摘要

In the production of mineral wool, the melting and crystallization behaviors of slag are the key issues to determine the final quality of mineral wool. In this study, three synthetic ferronickel slags with different B_2O_3 contents have been prepared, and the effect of B_2O_3 on the melting ranges of the slags has been investigated by single hot thermocouple technique (SHTT). Meanwhile, the isothermal crystallization characteristics of the samples were studied by high-temperature confocal scanning laser microscope (CSLM). The results showed that the initial and complete melting temperatures decreased with the increase of B_2O_3 content. Meanwhile, from the time-temperature-transformation diagrams, the crystallization incubation time increased with the increase of B2O3. The crystal morphology formed in the slags was columnar.
