  • Method for manufacturing high-strength formed coke in slight mutual agglomeration using horizontal type coke oven battery
    Patent number: 4110169
    Abstract: A plurality of different types of raw material coal fines are sieved to a size not exceeding 1.5 mm; said sieved raw material coal fines are blended so as to satisfy the following conditions:(a) AP index: 75 at the minimum,(b) Mean maximum reflectance: 1.20% at the minimum, and(c) A [dilatation] - [contraction] value of from -2 to +5% when carbonized under conventional conditions in a horizontal type coke oven battery at a heating rate of 5.degree. C/min. (350.degree. - 600.degree. C);said blended raw material coal fines thus obtained are mixed with a binder and formed to produce a formed coal; and then, said formed coal thus obtained is charged into a horizontal type coke oven battery and carbonized, whereby a high-strength formed coke for blast furnace is a slight mutual agglomeration is manufactured.
