Abstract
The utility model relates to a layered briquette, belonging to the technical field of coking. In the utility model, the charcoal is coked by layers in the coking process, and the influence of vertical cracks of foundry coke to block degree and the irregularity of transverse crack are solved. According to the technical scheme of the utility model, the bottom layer of the tamped layered briquette has the thickness of 200-300mm, 4 to 6 layers with the thickness of 150-300mm are tamped on the bottom layer, and a partition which is a grass paperboard is arranged between every two adjacent layers. A layer of middle coal is laid on the top layer of the made layered briquette at a thickness of 40-60mm. The utility model can be applied to the technical field of coking furnace coal charging.
Description
Technical field
A kind of layer-stepping briquette of the utility model belongs to the coking technology field.
Background technology
Foundry coke requires to have bigger lumpiness, therefore guarantees the coking lumpiness of foundry coke, and quality and the productive rate that improves foundry coke had great significance.The existing mode of coalingging is for to be pressed into briquette with pressing machine integral body, and the shortcoming of this mode is, because the influence of longitudinal crack, transverse crack, the coke lumpiness is little, and qualification rate is low.
The utility model content
For overcoming the deficiency of prior art, the utility model provides a kind of layer-stepping briquette, and charcoal is realized the layering coking in the process of coking, has solved the foundry coke longitudinal crack to the influence of lumpiness and the irregularity of transverse crack.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of layer-stepping briquette, and the structure after making firm by ramming is: underlayer thickness 200～300mm, make 4～6 layers again firm by ramming above the bottom; Every layer thickness 150～300mm accompanies partition between every adjacent two layers.Described partition is careless paperboard.Briquette top layer bedding one layer thickness making is the middle coal of 40～60mm.
The utility model is compared the beneficial effect that has with prior art:
The mode that the utility model adopts layering to make firm by ramming is made briquette; Coal is realized the layering coking in the process of coking; Solved the foundry coke longitudinal crack to the influence of lumpiness and the irregularity of transverse crack; The horizontal slip layer is set with the transverse crack that intercepted longitudinal crack, standard with careless paperboard, thereby has thoroughly solved the lumpiness problem of foundry coke.Coal can reduce the ashing rate in top layer covering one deck in the process of coke ashing, improves the productive rate of coke.Final formation coke lumpiness is moderate, and intensity improves, and qualification rate increases.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 is that bottom, 2 is that partition, 3 is middle coal.
Embodiment
As shown in Figure 1, a kind of layer-stepping briquette, the structure after making firm by ramming is: bottom 1 thickness 200～300mm, make 4～6 layers above the bottom again firm by ramming, every layer thickness 150～300mm accompanies between every adjacent two layers and cuts off 2.Described partition 2 is careless paperboard.Briquette top layer bedding one layer thickness making is the middle coal 3 of 40～60mm.
Embodiment 1: in the process of coalingging; Lay one deck grass paperboard when making the back underlayer thickness firm by ramming for 200mm; According to said method make 5 layers afterwards firm by ramming; Every lay one deck grass paperboard at a distance from 180mm, lay the thick middle coal 3 of 50mm at top layer at last, the briquette that forms 12800mm * 3430mm * 1150 specifications is at last sent into coking chamber and is carried out coking.
Embodiment 2: in the process of coalingging, lay one deck grass paperboard when making the back underlayer thickness for 300mm firm by ramming, according to said method make 4 layers afterwards firm by ramming, every separated 300mm lays one deck grass paperboard, lays the thick middle coal 3 of 40mm at top layer at last.
Embodiment 3: in the process of coalingging, lay one deck grass paperboard when making the back underlayer thickness for 250mm firm by ramming, according to said method make 6 layers afterwards firm by ramming, every separated 150mm lays one deck grass paperboard, lays the thick middle coal 3 of 60mm at top layer at last.
The utility model can reduce the coke crackle, absorbs the string stress along the coking chamber direction, thereby produces the bulk foundry coke, has improved the productive rate and the quality of foundry coke.
Claims (3)
