The problem of the prediction of a critical situation during continuous casting in common steelmaking practice is faced through different traditional soft–computing techniques: the task is to divide the data in two classes corresponding to good and bad casting behaviour respectively. Moreover, a novel algorithm, the Model–based method, is presented. The performance obtained by the different tec...

As a valuable byproduct of iron-making process, blast furnace slag contains tremendous amount of sensible heat. Granulation of blast furnace slag is the first step for its heat recovery. Due to environmental and energy issues, dry centrifugal granulation has received a considerable amount of attention. However, the flight dynamics of blast furnace slag, which is of great importance for size des...

The purpose of this study was to investigate the reuse of desulfurization slag in cement clinker production and its influence on the formation of clinker phases. The desulfurization slag that mainly contained Ca and Si was identified as non-toxic, and thus it should be suitable to be reused in clinker production. The addition of desulfurization slag increased the melt phase during clinkerizatio...

Alkaline treatment with steel slag and NaOH addition were investigated under different pH conditions for the fermentation of waste activated sludge. Better performance was achieved in steel slag addition scenarios for both sludge hydrolysis and acidification. More solubilization of organic matters and much production of higher VFA (volatile fatty acid) in a shorter time can be achieved at pH10 ...
