Abstract
The invention discloses a kind of tamping coking coals, are related to coke making and coal blending field；The tamping coking coal includes middle cleaned coal, and the middle cleaned coal is obtained by extracting from the middle coal of coking coal；The present invention provides a kind of method for the coke making and coal blending that middle cleaned coal participates in tamping coking, develops a kind of new coal for coking resource, alleviates coking coal status in short supply to a certain extent；It is interior close with the coking coal of its main body in the evolution process of ingredient and coal etc. because middle cleaned coal is extracted from the middle coal of coking coal, and the harmful metal elements content for analyzing wherein Coke Quality influence is seldom, does not influence coke quality；The supplying of middle cleaned coal can not only reduce cost, save coking coal resource, while providing new approaches for coal chemical enterprise cost efficiency.
Description
Technical field
The present invention relates to coke making and coal blending fields, and in particular to a kind of tamping coking coal for being added to middle cleaned coal.
Background technique
Coke is the important source material and fuel of metallurgy industry, with the fast development of China's steel industry, iron and steel output
It is skyrocketed through, the demand of STRENGTH ON COKE is increasing, and the requirement of quality is also higher and higher.Coke quality is seriously by China's coking coal
The restriction of shortage of resources.Therefore, development mill coal substitution or part substitution coking coal coking are very urgent, especially to China
And there is important strategic importance.
Although the coal resources in China are abundant, the coal of suitable coking is few, and the Area distribution of resource is also extremely uneven
Weighing apparatus, the reserves of the especially good coking coal such as coking coal and rich coal are less, and constantly increase plus dosage, and coking coal resource is opposite
Shortage.Coking coal reserves only accounts for the 26.25% of coal in China gross reserves, wherein strong caking coal is rare, rich coal, gas rich coal and coking coal
The 12.81% and 23.61% of coking coal reserves is accounted for respectively, and further includes a considerable amount of difficulties in these strong sticky coal reserves
Choosing, high sulfur coal resource, cannot act as coking raw material, therefore, China's strong cohesive property coal resource is rare and valuable.So benefit
Coking cost is reduced, coke matter is improved by being developed and being expanded the type of coal for coking with the existing coal resources advantage in China
Amount becomes the effective way for solving coking coal shortage, and can adapt to the needs of long-run development.
The cleaned coal that the raw coal of coking coal, rich coal, bottle coal, the lean coal of common coal-blending coking all etc. goes out after washing, matches
The cold strength and hot strength of the coke that coal coking primarily guarantees, coke ash can because chlorine adding ratio variation and intensity
It is primary to guarantee etc. that higher or relatively low situation occur in reasons, now enter to wash using the middle coal after raw coal washing as raw coal is secondary, mention
High coal washing ash content proposes secondary cleaned coal, adjusts the coke ash problem during coal-blending coking.To guarantee with middle coal coking mistake
Coke cold conditions hot strength in journey is unaffected, and coking worker has done a large amount of exploratory development in terms of coal-blending coking.
Summary of the invention
Overcome the deficiencies in the prior art of the present invention, it is therefore an objective to provide and prepare the coking of middle cleaned coal in a kind of tamping coking and use
Coal.
In order to solve the above technical problems, the technical scheme adopted by the invention is as follows:
A kind of tamping coking coal, the tamping coking coal include middle cleaned coal, and the middle cleaned coal is by from coking coal
Middle coal in extract and obtain.
Preferably, the tamping coking coal includes the middle cleaned coal for accounting for the 1%-5% of coal blending total weight.
Preferably, the component including following weight percent: coking coal: the 15%-30% of coal blending total weight is accounted for；1/3 coking coal: it accounts for
The 15%-30% of coal blending total weight；Middle cleaned coal: the 1%-5% of coal blending total weight is accounted for；Lean coal: the vitrinite reflectance R of lean coalmax?
The specific sections ratio > 65% of 1.50%-1.75%, lean coal accounts for the 10%-30% of coal blending total amount；Bottle coal: vitrinite's reflection of bottle coal
Rate RmaxIn the specific sections ratio < 75% of < 0.75%, bottle coal accounts for the 25%-40% of coal blending total amount.
Preferably, the middle cleaned coal are as follows: ash content < 20%, volatile matter 18-25%, adhesive index value are 20-40, and sulphur contains
Amount is 0.4-0.7%, and every metal element content in the middle cleaned coal is Na2O is 0.55%, K2O is 0.14%, Fe2O3For
2.97%, GaO 3.3%, MgO 0.48%.
The present invention provides a kind of method for the coke making and coal blending that middle cleaned coal participates in tamping coking, develops a kind of new coking
With coal resource, coking coal status in short supply is alleviated to a certain extent.The supplying of middle cleaned coal can not only reduce cost, section
About coking coal resource, while new approaches are provided for coal chemical enterprise cost efficiency.
Compared with prior art the invention has the following advantages:
1) coal is very low as electric coal selling price in itself, at 200 yuan or so, enter again the cleaned coal price after washing 600 yuan with
Interior, the modern times replace coking coal of the price at 1100 yuan, and coal price of the dosage in 1-5% can reduce by 5 yuan -25 yuan.
2) because middle cleaned coal is extracted from the middle coal of coking coal, in evolution process of ingredient and coal etc. and
The coking coal of its main body is close, and the harmful metal elements content for analyzing wherein Coke Quality influence is seldom, does not influence coke
Quality.
3) cleaned coal is used as power generation in, and the at high cost and wasting of resources can save high-quality refining instead of coking coal coal-blending coking
The amount of coking coal, secondary returning are matched, and are economized on resources.
4) coke ash requires as less than 12.5%, the ash content for the coke usually produced reaches 12.3%, although meeting
The requirement of standard, but there is 0.2% ash content to waste, if quality is not superfluous after being replaced with 1% middle cleaned coal, one ton of coal
Low 5 yuan at instinct.Under the premise of guaranteeing coke quality index, reduce costs.
Specific embodiment
The present invention will be further described in detail With reference to embodiment.
Coal of the present invention is Domestic Coal, and the coal analysis of each single grade coal the results are shown in Table 1.
1 single grade coal of table and clay Industrial Analysis result
The weight percent of each single coking coal and middle cleaned coal proportion are as follows: bottle coal: 25%-40%；1/3 coking coal: 15%-30%；Lean coal:
10-30%；Coking coal: 15%-30%；Middle cleaned coal: 1-5%.
The specific embodiment of Coal Blending Schemes is shown in Table 2.
2 Coal Blending Schemes of table
Embodiment 1-4 and the resulting coke of comparative example are in production system, after each single coking coal first cooperates with middle cleaned coal
Under the process conditions of crushing, the data result of 4.3 meters of tamping coke furnaces of production capacity 1,000,000.
The above content is combine specific preferred embodiment to the further description done of the present invention, and it cannot be said that
A specific embodiment of the invention is only limitted to this, for those of ordinary skill in the art to which the present invention belongs, is not taking off
Under the premise of from the present invention, several simple deduction or replace can also be made, all shall be regarded as belonging to the present invention by being submitted
Claims determine scope of patent protection.
