Description
Technical field
The present invention relates to anthracite, bottle coal coal-blending coking production technical field, especially a kind of large scale supplying anthracite,
The tamping coking technique of bottle coal.
Background technique
China's coking coal only accounts for 37% or so of coal reserves, though kind is more complete, structure and Regional Distribution are all very
It is uneven.Weakly caking bottle coal reserves are more, up to 55.9%, and are easy coal separation；Cohesiveness and the preferable rich coal of coking capacity and coke
Coal reserves only has 14.6%, 17.1% respectively, and mostly or difficult separation coal, and these coals are concentrated mainly on North China.Coking
This resource situation of coal determines the situation of China's high-quality caking coal chronic shortage, also seriously restricts holding for coking industry
Supervention exhibition.
China's anthracite resource is extremely abundant, and is distributed more equilibrium, and most area contains anthracite, anthracitic
Price is lower, and coal quality is good, and ash, sulfur content are lower, and also there is an anthracite on most of coal chemical enterprise periphery at home, haul distance generally compared with
Closely.But it since anthracite is almost without caking property, is not used substantially during previous coal-blending coking.
Bottle coal is that one of biggish coal of occupation ratio in coking coal reserves has been verified in China, and degree of metamorphism is low, volatilization
Point higher, cohesiveness is generally weaker than gas rich coal, rich coal, 1/3 coking coal and coking coal etc., so the ratio occupied in coal blending at present is very
It is few.
It therefore, can be to alleviate the anthracite of large scale, the supplying coking of weakly caking bottle coal coking coal resource shortage, expand
Big coking resource reduces production cost and improves the effective way of Business Economic Benefit, significant.
Summary of the invention
The object of the present invention is to provide a kind of large scale supplying anthracites, the tamping coking technique of bottle coal.The present invention is big
Ratio refines metallurgical coke using cheap anthracite (mill coal) and bottle coal (weakly caking coal) coal blending, and technique is very easy, this work
Skill can effectively expand the coking coal of coking resource, the shortage that economizes on resources, moreover it is possible to reduce coking cost, there is very big economy and society
Benefit.
Technical solution of the present invention: a kind of large scale is incorporated the tamping coking technique of anthracite, bottle coal, it is characterised in that:
The technique includes the following steps:
First mixed coal is put into tamping tool and is made firm by ramming, making completion firm by ramming and obtaining density is 1.05-1.10t/m3Briquette, then will

In at least 50% granularity be less than 0.5mm.
Large scale above-mentioned is incorporated in the tamping coking technique of anthracite, bottle coal, by weight percentage, the mixed coal
In have 93% granularity be less than 3mm.
Large scale above-mentioned is incorporated in the tamping coking technique of anthracite, bottle coal, and the mixed coal is before being put into tamping tool
It is uniformly mixed.
Large scale above-mentioned is incorporated in the tamping coking technique of anthracite, bottle coal, and the humidity of the briquette is 10%.
Beneficial effects of the present invention:
Large scale anthracite and bottle coal can be added to mixed coal refining metallurgical coke by technique of the invention, and technique is very
Simply, it only needs first to make mixed coal firm by ramming, then can carry out coking；The present invention is by mill coal (anthracite) and weakly caking coal (gas
Coal) it is efficiently used, it is effective to expand coking resource, additionally it is possible to which that the coking coal for the shortage that economizes on resources has very big society
Benefit；Large scale of the present invention carries out coking using cheap anthracite and bottle coal, coking cost can be greatly lowered, and be made
Coke can reach secondary metallurgical standard, have very big economic benefit.
