Description
Technical Field
The utility model relates to a sintering technology field, concretely relates to improve sintering machine of sintering rate.
Background
The sintered ore is the main iron-containing raw material in the iron-making process of iron and steel enterprises, and accounts for about 70 percent. The sintering process not only produces sinter used for ironmaking, but also treats various wastes such as iron-containing dust, sludge and the like of iron and steel enterprises. Sintering is to mix various powdery iron-containing raw materials with fuel, flux and water in proportion, the mixture is granulated on a mixer, the mixture is laid on a sintering machine, the upper part is ignited, the lower part is ventilated, sintering is carried out from top to bottom, the fuel burns to release heat during sintering, high temperature is formed, a series of physical and chemical reactions are promoted, a certain amount of liquid phase is generated by softening and melting of part of fusible substances in the mixture, mineral powder particles around wetting and bonding are generated, when the fuel is consumed completely, the temperature is reduced, the liquid phase is solidified, and a porous product with certain strength is formed, namely sintering ore.
The sintering process is carried out starting from the surface of the bed and proceeding gradually downwards, so that there is a pronounced delamination along the height of the bed. The material layer being sintered is divided into five layers from top to bottom, namely a sintered ore layer, a combustion layer, a preheating layer, a drying layer and an over-wet layer. With the movement of the sintering trolley, the five layers appear in sequence and disappear in sequence, and finally, a sintering ore layer is left.
Besides the influence of the porosity of the sinter bed, the combustion bed and the over-wet bed are main areas for limiting the sintering permeability, so that downward air draft is blocked, the combustion speed is reduced, and the sintering productivity is reduced.
CN201910944418.0 discloses a production method for improving sintering permeability of a thick material layer, wherein a support prefabricated by return ores, steel slag, dedusting ash, cement and the like is added in a sintering material. The method needs a special bracket and manual putting, the principle is only to support the material layer and reduce the pressure effect born by the lower material, and although the improvement of air permeability is facilitated, the method does not fundamentally solve the problem of two areas (a combustion layer and an over-wet layer) for limiting the air permeability of the material layer. CN200910078993.3 discloses a burden reducing device for a sinter bed, the burden reducing device in the method is easy to be lost, the replacement of the device needs to be stopped, the maintenance and updating labor amount is large, the cost is high, and the burden reducing device occupies the space of sintering mixture on a sintering trolley, thereby reducing the yield of sinter. In addition, JP2 293586, JP4 168234, JP5 43950, JP6 129775, JP6 323745 and other methods which adopt a trapezoid or rectangular sinter bed load reducing plate to reduce the load of the bed and thus improve the air permeability of the bed have the defects of poor load reducing effect, easy damage, inconvenient replacement, high cost and the like, and cannot completely solve the negative effects of the supporting device. CN201710164243.2 discloses a sintering pallet using parallel supporting frames, which supports a sinter bed by providing a supporting grid with a supporting function to improve air permeability, but in actual operation, because a bedding material distributor is located in the pallet, and the bedding material distributor limits the bedding material height, such a supporting grid cannot be implemented.
