Considering the BSSF steelmaking slag generated in a Brazilian steelwork, it would be worth to separate iron and calcium from it, with objective of increasing its content, or producing Fe2O3 CaO by selective precipitation cations aqueous solution. In this way, materials could produced used in-house, e.g., sintering plant. This possibility was explored through acid leaching for an industrial sam...

Ground granulated blast furnace slag is widely used as a mineral admixture to replace partial Portland cement in the concrete industry. As the amount of slag increases, the late-age compressive strength of concrete mixtures increases. However, after an optimum point, any further increase in slag does not improve the late-age compressive strength. This optimum replacement ratio of slag is a cruc...

In the present work, effect of dephosphorization endpoint temperature on hot metal was studied for double slag converter steelmaking process under conditions low and basicity by industrial experiments. range 1350–1450 °C, with an increasing temperature, ratio phosphorus distribution first increase then decrease. The content in decreases increases at end dephosphorization. At 1385–1410 is higher...
