Abstract
The process of zones formation in the layer was investigated. A new research method was developed for the saturation zone in the layer by discharge of sintering bowls with the structure conservation. Sintering mixture was pelletized using of melt paraffin instead of water. The destruction of the granules in areas with a dry charge material above the zone of saturation forms a zone of fine fractions with a height of about 6 mm with low gas permeability. Zone of fines increases the pressure loss in 1.4 times and the shrinkage of the layer – by 20–25 mm. Fines form a channel course of the gases in the zone of saturation clogging the channels with a diameter less than 0.6 mm. Negative impact on the permeability of the destruction layer of the pellets in the drying zone – intensive heating zone – and the saturation zone should be reduced to improve the efficiency of the sintering process.
