In the present work, dephosphorization experiments by using new double slag converter steelmaking process (NDSP) has been carried out in a 180 ton top-bottom combined blowing under low temperature range of 1345–1450°C and basicity about 1.50. With increasing endpoint temperature, ratio, P2O5 content phosphorus distribution ratio logLP first increase then decrease. The apparent equilibrium const...

Phosphorus-containing converter slag is a common waste in the iron and steel industry, has characteristics of high generation low secondary-utilization values; however, high-phosphorus content limits its ability to be recycled during steelmaking process. In this study, dephosphorization behavior by carbothermal reduction was studied through experiments thermodynamic calculations. The results sh...

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...

In this study, the early-age strain–stress development of mixtures containing slag cement was measured on uniaxially restrained specimens using a specially designed testing frame starting right after casting. It was found that thermal deformation dominates early-age stress development in low w/cm and low slag cement paste systems. While for concrete, autogenous shrinkage is the major contributi...

Vitrification is considered to be an attractive technology for bottom ash treatment because it destroys the hazardous organics, contributes to immobilization of the heavy metals, and additionally it reduces drastically the volume. The main components of the vitrified bottom ash slag are SiO2 , CaO, Al2 O3 , Fe2 O3 , Na 2 O and MgO, and the compositions have direct effect on the glass formation ...
