The optimized blast furnace design is the prerequisite for low-carbon smelting. salamander depth and bosh angle are key parameters, which determine longevity. In this paper, physical mathematical force model of deadman cooling stave was established. relationship between operating parameters depth, as well angle, analysed, gas flow scouring curve proposed. following results were obtained: first,...

The effect of the curing in a carbonated ambient of the solids obtained after the stabilization/solidification (S/S) of metallurgical waste using geopolymerization technology is described in this paper. The electric arc furnace (EAF) dust used to stabilize contains hazardous metals such as Pb, Cd, Cr or Zn. Different geopolymeric agents as potassium hydroxide, potassium silicate, metakaolin and...

The purpose of this study was to evaluate the performance of porous vegetation concrete block made from blast furnace slag cement containing industrial by-products such as blast furnace slag aggregate and powder. The blocks were tested for void ratio, compressive strength and freeze-thaw resistance to determine the optimal mixing ratio for the porous vegetation block. An economic analysis of th...
