Abstract
The invention discloses an Outer Mongolia coking coal-participant coking coal blending method. The method comprises a step of blending of all single coking coals, and the single coking coals comprise, by weight, 3-8% of gas-rich coal, 5-15% of rich coal, 15-20% of 1/3 coking coal, 15-20% of the Outer Mongolia coking coal, 30-38% of coking coal and 10-15% of lean coal. According to the invention, the Outer Mongolia coking coal participates in the coking coal blending according to a 1/3 coking coal application method, so the effective utilization of the Outer Mongolia coking coal resource can be realized under non-grading fragmentation and briquette technology or tamping coking technology conditions, and the coke quality is not deteriorated.
Description
Technical field
The invention belongs to coke making and coal blending method, refer to particularly the coke making and coal blending method that a kind of outer illiteracy coking coal participates in.
Background technology
In recent years, coking industry output increases sharply, coke quality steadily improves, and has substantially satisfied the blast-furnace smelting demand, also causes coking coal in short supply simultaneously, and the contradiction that high-quality caking coal is in short supply is particularly outstanding.Each coal chemical enterprise has to seek new resource at home and abroad from area, western border area, outer illiteracy, Australia, Canada etc.Though apparent index is very high, such as G value, Y value height, there is certain otherness in the various places coking coal in rheological, swelling property and coking microstructure because the condition of coal formation is different.
Outer illiteracy coking coal, volatile matter are between 24～26%, and the adhesive index value is greater than 85, the maximum thickness of plastic layer Y value is greater than 17mm, inferior turgidity b value 55～75 difficult to understand, maximum Giseeler fluidity MF100～300ddpm, but single coal coking coarse grain pattern structure only 35～40%, maximum vitrinite reflectance of planting
Be 0.95%～1.05%.If this outer illiteracy coking coal only should be the high-quality coking coal by GB, but metamorphic grade is singly planted the inclined to one side 1/3 coking coal feature of coal coking micro-structural feature between 1/3 coking coal and coking coal.
Summary of the invention
Purpose of the present invention is exactly the singularity for outer illiteracy coking coal, and the coke making and coal blending method that provides a kind of outer illiteracy coking coal to participate in is optimized adapted with outer illiteracy coking coal, coking coal resource is rationally utilized, not deteriorated coke quality.
For achieving the above object, the coke making and coal blending method that outer illiteracy coking coal provided by the present invention participates in, it comprises singly plants the step that coking coal is mixed with each, usedly singly plants coking coal and weight percent is: gas-fat coal: 3%～8%; Rich coal: 5%～15%; 1/3 coking coal: 15%～20%; Outer illiteracy coking coal: 15%～20%; Coking coal: 30%～38%; Lean coal: 10%～15%.
Preferably, the used single kind coking coal of the present invention and weight percent thereof are: gas-fat coal: 5%; Rich coal: 10%; 1/3 coking coal: 15%; Outer illiteracy coking coal: 20%; Coking coal: 38%; Lean coal: 12%.
Among the present invention, the Coal Characteristics of used outer illiteracy coking coal:
1. volatile matter is between 24%～26%, Y value＞17mm;
2. vitrinite reflectance distributes: the average maximum reflectivity of vitrinite
3. process performance index: adhesive index value＞85; Giseeler fluidity is measured: maximum Giseeler fluidity MF100～300ddpm; Inferior turgidity b:55 difficult to understand～75.
4. list is planted coal coking constitutional features: single kind coal coking coarse grain is inlayed and is reached 35%～40%.
Other used each single ature of coal of planting coking coal all meets the classification indicators in the corresponding national standard.
Among the present invention, control coking coal coking coarse grain pattern structure is more than 50%.
In the process of being mixed, the control mixed coal satisfies following processing parameter: the adhesive index value is 79～82, maximum thickness of plastic layer Y value: 17～19mm.
The present invention proposes outer illiteracy coking coal by the method for 1/3 coking coal adapted, only be equivalent to high-quality 1/3 coking coal level because cover coking coal list kind coal coking coarse grain pattern structure outward, Coke Quality is favourable, can reduce other 1/3 coking coal and Blending of Coking Coals simultaneously, reduces high-quality coking coal adapted amount.
The present invention has following advantage compared with prior art:
1) method of employing outer illiteracy coking and mixing coal by participation of coking coal provided by the invention can be under the processing condition without graded crushing, moulded coal technique or tamping coking, and to its efficient utilization of resource, and coke quality does not have deteriorated.Coking on the cokery more than 4 meters, its Indexes on Coke Strength: shatter strength M40 is greater than 80%, and post-reaction strength CSR is greater than 62%.
2) present technique breaks through the classification of traditional GB only by the restriction of coking coal application method, proposes the optimization application method of ature of coal outer illiteracy coking coal between 1/3 coking coal and coking coal, reaches the reasonable utilization of coking coal resource, not deteriorated coke quality.
