高温熔渣内生气源发泡性能和泡沫流变特性的研究

The mechanism of the heat transfer and the reaction of decomposition and reduction in molten slag has been analyzed. By the mass and heat balance the relationship between the gas quantity of the reaction and time was determined. Thereupon the foaming equations originated from reaction have been established. With the developed equipment the experiment was carried out for determing the relationship between the foaming heigh and time. By means of the experimental results in labor, the foam behavior parameters originated from reaction in the molten slag were given through the self-developed calculation program. With these parameters the influence on the foaming processes under different condition were quantitatively discussed and analyzed in details. Specially, the relationship between the foam behavior parameters and characteristic of the physical chemistry of molten slag could be found with the similar theory. The culculation method for the foam behavior parameters has been directed through the characteristic of the physical chemistry of molten slag. The results of the reseach provide a necessary theory foundation and analysis method for practice using of metallurgical processes.
