Abstract
The invention provides a novel coaling mode in coking process, belonging to the technical field of coking. According to the invention, layered coking of coal is realized in coking process, so that the influence of vertical cracks of the foundry coke to the lumpiness and the irregularity of transverse cracks are solved. The technical proposal of the invention comprises the following steps: using a mode of layered tamping to prepare coal cakes, firstly filling a layer of coal at the bottom, after tamping putting a partition on the first layer of coal, then temping another layer, and circulating repeatedly successively until the required size is achieved. The partition is a grass paperboard, and finally a layer of middlings is placed on the top of the prepared coal cake. The invention is applied in the technical field of coaling of a coke oven.
Description
Technical field
The novel mode of coalingging in a kind of process of coking of the present invention 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.
Summary of the invention
For overcoming the deficiency of prior art, the present invention provides the novel mode of coalingging in a kind of process of coking, and coal 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 present invention adopts is: the novel mode of coalingging in a kind of process of coking, the mode that adopts layering to make firm by ramming is made briquette.At first filling one deck coal in the bottom is made the back firm by ramming and on the first layer coal, is placed partition, and then makes one deck firm by ramming, and circulation successively is up to reaching required size.Described partition is careless paperboard.Last middle coal at briquette top layer bedding one deck of making.
The present invention compares the beneficial effect that has with prior art:
The mode that the present invention 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.
Embodiment
The novel mode of coalingging in a kind of process of coking, the mode that adopts layering to make firm by ramming is made briquette.The mode that described layering is made firm by ramming is made briquette, and at first filling one deck coal in the bottom is made the back firm by ramming and on the first layer coal, placed partition, and then makes one deck firm by ramming, and circulation successively is up to reaching required size.Described partition is careless paperboard.Middle coal at briquette top layer bedding one deck of making.
Embodiment 1: in the process of coalingging; Lay one deck grass paperboard when making back the first layer 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 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.
Present method 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.
