Description
Technical field
The present invention relates to the coke making and coal blending method of 1/3 coking coal, belongs to coal-blending coking technical field, is specifically related to one kind
Gu-softening temperature section is the coke making and coal blending method of more than 90 DEG C 1/3 coking coal.
Background technology
China's coal resource enriches, but coking coal resource is in short supply, and skewness weighs in limited coking coal resource.
In the coal reserves verified, coking coal reserves only accounts for the 26% of coal gross reserves, and coking coal only accounts for coking coal reserves
17.57%, wherein, rich coal accounts for the 10% of coking coal reserves.And in coal-blending coking, burnt rich coal should typically account for 50%-60%, because
This, contradiction is serious between coking coal resource and the demand of coke making and coal blending.
In order to improve coke quality and reduce production cost, coking worker in various countries' gradually starts to pay attention to non-master
Come in the application study of coking coal, and the coal that 1/3 coking coal is higher as content in China's coal resource deposit, how to use 1/3 Jiao
Coal has turned into the required problems faced of coking worker.1/3 coking coal is as a kind of degree of metamorphism between coking coal and rich coal
Coal, its complexity are higher than burnt rich coal, and use of the China to 1/3 coking coal depend on traditional coal index and
Certain lack be present in the combined index of the vitrinite reflectance of coal petrography index and its distribution, both indexs and both indexs
Fall into, it is impossible to reasonable employment comprehensively is accomplished to 1/3 coking coal.
Chinese invention patent application (application publication number：CN104804755A, data of publication of application：2015-07-29) disclose
Gu-soft silicon carbide is the coke making and coal blending method of less than 85 DEG C 1/3 coking coal, Coal Blending Schemes disclosed in the application for a patent for invention are：
1) Giseeler fluidity measure is carried out to 1/3 coking coal, selection wherein consolidates 1/3 coking coal that softening temperature section is 70~85 DEG C and is designated as I class
1/3 coking coal, 85 DEG C of temperature range ＞ 1/3 coking coal are designated as other 1/3 coking coal；2) coking coal of I class 1/3 is pressed into following mass percent
