Abstract

The chemical structure of mineral wool fiber was investigated by using Fourier Transform Infrared Spectroscopy (FTIR). Next, the glass transition temperature and the crystallization temperature of the fibers were studied. Finally, the crystallization kinetics of fiber was studied. The results show that the chemical bond structure of fibers gets more random with the increase of acidity coefficient. The crystallization phases of the fibers are mainly melilites, and also a few anorthites and diopsides. The growth mechanism of the crystals is three dimensional. The fibers with acidity coefficient of 1.2 exhibit the best thermal stability and is hard to crystallize as it has the maximum aviation energy of crystallization kinetics.

Abstract

Basic glass with stable properties was prepared from molten blast furnace slag by using the melting method. The heat treatment regime of glass-ceramics was determined by differential thermal analysis of the basic glass. Optimum heat treatment parameters were selected and the crystal growth pattern of glass-ceramics was analyzed by X-ray diffraction and scanning electron microscopy.The results show that the optimum heat treatment parameters of glass-ceramics are the nucleation temperature of 850℃ for 1.5 h and the crystallization temperature of 935℃ for 1 h. The crystallization grows from the surface to interior gradually. The mechanical properties of the prepared glass-ceramics,such as bending strength,acid and alkali resistance,and hardness,are better than those of ordinary marble.

Abstract

The process of granulation in blast furnace slag (BFS) by gas quenching can effectively recover the waste heat of BFS and improve the value-added nature of the BFS byproduct. With decreasing temperature, BFS crystallizes into melilite, anorthite, spinel, etc. Mineral crystallization, however, is not conducive to the production of amorphous BFS beads. This study uses thermodynamic simulation and remelting experiments to study the influences of basicity, acidity, and the MgO and Al2O3 content of the BFS on the crystallization. By controlling the composition of the BFS, mineral crystallization in the process of granulation in BFS, by gas quenching, could be prevented. The results show that increasing the basicity of the BFS causes the mineral crystallization temperature to increase rapidly. The mineral phase then crystallizes at a higher temperature, which is not conducive to the formation of an amorphous phase. Increasing the acidity of the BFS can greatly decrease the crystallization temperature, e.g., when the acidity increases to 1.3, amorphous BFS beads can be obtained at the gas quenching temperature (1623 K). Although increasing the MgO and Al2O3 contents in the BFS had little effect on the crystallization temperature and yield, the preparation of amorphous BFS beads by gas quenching could be realized by adjusting the acidity of the BFS.
