The invention discloses a coking mixed
coal prepared via adding of a reclaimed material, and a coking
coal blending method. The coking mixed
coal is composed of, by weight, (16-2N)% of fat coal, 19 to 21% of high-sulphur coal, 4 to 6% of 1 / 3 coking coal, 39 to 41% of coking coal, (7-N)% of meager lean coal, (12+2N)% of gas coal, and N% of the reclaimed material, wherein N<=5; the reclaimed material contains 21 to 24wt% of beta resin. According to the coking
coal blending method, beta resin with
adhesive effect is used for realizing combination of the coking mixed coal with coking
coal blending technology, and is used for replacing a part of fat coal into coking coal to produce
coke, so that coking coal source is widened, the using amount of expensive fat coal is reduced, and
coal blending cost is reduced. The coking coal blending method is capable of widening the plastic temperature range of coking coal, realizing better connection of different kinds of coal, increasing cokeability in coking process, promoting anisotropic generation, ensuring that
coke quality is capable of satisfying
coke requirements of large blast furnaces, and at the same time increasing the using amount of low
adhesive performance meager lean coal in coking coal blending, and reducing coal blending cost greatly.
