Thick-bed sintering feed surface-spraying covering agent and spraying method thereof

InactiveCN103215442ATake advantage ofPlay the role of material surface insulationCombustionSurface layer
The invention discloses a thick-bed sintering feed surface-spraying covering agent and a spraying method thereof. The thick-bed sintering feed surface-spraying covering agent is mixed from the following materials: carbon concentrate, expanded slag balls and sintered return mine. The surface layer temperature of the sintering feed layer, which is sprayed with the covering agent, is higher than the surface layer temperature of the sintering feed layer not added with the covering agent, which is far higher than the ignition temperature of the fuels; the upper layer of the fuels can be continuously combusted after a combustion zone is moved downwards, so that the defect that the heat of the upper sintering feed is insufficient is overcome. The covering agent not only can be used for supplementing the upper heat of the sintering feed layer, but also can be used for achieving the effect of the material surface heat preserving agent and ensuring the good air permeability, so that thickness of the upper material layer without sufficient agglomeration strength is reduced, the yield and the strength are effectively improved, and the total carbon content is reduced, and therefore, the heat of the lower part is free of an excess and super-fusion phenomenon, the sintering machine utilization coefficient, the sinter yield and the strength under the whole thick-bed sintering condition are obviously improved. Moreover, the residual carbon resource in the carbon powder, i.e., the product obtained by gas ash beneficiation, is sufficiently utilized.
