The value of by-products and residues from steel production processes stem from their metal content and their inherent heat of combustion. However, the organic contents of sludge, scale and of other ferrous residuals make it difficult to recycle them via the conventional sinter process due to low burning rates. Insufficient burning rates will increase the dust load, could harm the ESTP and is responsible for the formation of the blue haze. The Top-Layer-Sintering Process using a second ignition hood which ignites the second layer on top of the main sinterbed has opened an economical and ecologically clean way for returning waste materials to valuable blast furnace burden by sintering. In pot grate test series and semi industrial tests the process was optimized. An industrial recycling plant for treatment of organic containing residuals is now in operation.
