Description
Technical field
The present invention relates to coke making and coal blending technical field, particularly coke making and coal blending method.
Background technology
China's coke making and coal blending is mainly according to technical analysis index, coal petrography index and technology-coal petrography index at present, these indexs have been reacted coking coal to a certain extent and have been formed the ability of the coke button that certain physical strength is arranged, the air hole structure and the cold strength of gained coke from powdery under certain process conditions, but can not require to carry out quantitative coal blending at the coke thermal behavior, and there is certain limitation in above index to the ature of coal evaluation and the quantitative adapted of the coking coal of special genetic.
Summary of the invention
Technical matters to be solved by this invention is: a kind of method of coal petrology coal blending is provided, and this method can rationally be used each single coking coal of planting of special genetic.
A kind of method of coal petrology coal blending, its concrete steps are:
The first step, detect each single coking coal of planting, detect and comprise fugitive constituent, bonding index G value, coke microstructure composition;
Second goes on foot, designs each single blending ratio of planting coking coal, according to blending ratio respectively weighting add with each single coarse grain of planting the coking coal coking and inlay component, inertia component, same sex structure component, fugitive constituent, satisfy: the coal blending coke: coarse grain is inlayed component＞33%, inertia component 20-27%, same sex structure component＜6%, the coal blending fugitive constituent obtains blending ratio at 25-30%, by blending ratio each single coking coal of planting is mixed, obtains coal blending;
The 3rd goes on foot, gets the bonding index G of coal blending pattern detection coal blending value;
The 4th goes on foot, makes the following choice according to testing result:
The bonding index G of coal blending value is between 75-82, and coal blending is finished;
Or,
The bonding index G of coal blending value is not between 75-82, and circulation second goes on foot.
Compare with existing blending method, the inventive method is with ash, sulfur is as the coke making and coal blending controlling index, with fugitive constituent, bonding index G value and single micro-composition of coal coking of planting are as coal blending quality index system, make the coal blending fugitive constituent be controlled at 25-30%, the bonding index G of coal blending value is controlled at 75-82, coal blending coke coarse grain is inlayed component＞33%, inertia component 20-27%, same sex structure component＜6% obtains post-reaction strength greater than 56% high grade coke, having overcome prior art can not rationally use the ature of coal of special genetic, to the quantitative shortcoming of coal blending of given coke thermal behavior index, coking coal resource is rationally used, accurately coal blending improves coke quality.
Embodiment
The method embodiment 1 of coal petrology coal blending of the present invention, its concrete steps are:
The first step, detect each single coking coal of planting, detect and comprise fugitive constituent, bonding index G value, coke microstructure composition; The single microstructural method of coal coking of planting of mensuration: the microstructural burnt sample of mensuration coking single kind coal coking is crushed to 3-1mm after being heat-treated to 950 ℃ with the coke button of surveying the thickness of colloidal matter layer gained, makes mating plate then, by GB mensuration.
Testing result sees Table 1.
Second goes on foot, designs each single blending ratio of planting coking coal, and the number percent that each single kind coking coal accounts for the coal blending general assembly (TW) is:
Gas-fat coal 8%; 1/3 coking coal 35%; Rich coal 5%; Coking coal 38%; Lean coal 14%.
According to blending ratio respectively weighting add with each single coarse grain of planting coking coal and inlay component, inertia component, same sex structure component, fugitive constituent.
Coal blending coke coarse grain is inlayed component=(gas-fat coal) 4%*8%+ (1/3 coking coal) 26%*35%+ (rich coal) 52%*5%+ (coking coal) 56%*38%+ (lean coal) 16%*14%=35.5%＞33%; Satisfy.
Coal blending coke inertia component=(gas-fat coal) 12%*8%+ (1/3 coking coal) 15%*35%+ (rich coal) 18%*5%+ (coking coal) 21%*38%+ (lean coal) 37%+14%=20.3%; Satisfy 20-27%.
Coal blending coke same sex component=(gas-fat coal) 10%*8%+ (1/3 coking coal) 8%*35%+ (rich coal) 2%*5%+ (coking coal) 0%*38%+ (lean coal) 0%+14%=3.6%; Satisfy＜6%.
In like manner, weighting adds and calculates coal blending fugitive constituent 29.11%, satisfies 25-30%.
Obtain blending ratio, each single coking coal of planting is mixed, obtain coal blending by blending ratio;
The 3rd goes on foot, gets the bonding index G of coal blending pattern detection coal blending value; The bonding index G of coal blending value is 80.
The 4th step, bonding index G value are between 75-82, and coal blending is finished.
Above-mentioned each single coking coal of planting is state's producing coal.
