During the process of converter steelmaking,the oxidbillity of slag had an direct influence on the speed of melting slag,the viscosity of slag and the extent of sputter.
Based on the principle of thermodynamics, the authors have made much calculation of the thermal effect caused from oxidation and generation of monodrome alloys and slag.
This article briefly introduces the study that pure alkali - melting process treats the vacuum dezincing furnace slag and comprehensively recovers Ge, In, Ag, Pb and Zn from it.
The distensibility of BOF slag was measured by steam test method and the effect of size and ageing time on the distensibility was investigated.These gives evidence for application of BOF slag.
But above this gate, and behind it even to the mountains, he piled the thunderous towers of Thangorodrim, that were made of the ash and slag of his subterranean furnaces, and the vast refuse of his tunnellings.
