The paper described laboratorial investigations for determination of optimal technological parameters of agglomerate production with increased exhaustion in the layer with height to 400 mm at Magnitogorsk Iron and Steel Works. It was established that increase of exhaustion by every 100 mm H₂O leads to elevation of vertical rate of agglomerate sintering by 7.6%. Increase of the layer by every 50 mm leads to lowering of vertical sintering rate by 3.8%.
