Summary: | PROBLEM TO BE SOLVED: To provide a manufacturing method of coke capable of increasing intensity of manufactured coke by rationalizing pulverization particle size by a simple method without needs for specific device.SOLUTION: There is provided a manufacturing method of coke for manufacturing coke by dry distillating a coal charge obtained by blending a plurality of kinds of single coals, which includes a process A for screening each single col by a sieve with a predetermined opening, a process B for measuring total expansion ratio of a fraction with the predetermined opening or less, which is screened in the process A by a dilatometer, a process C for calculating a value Y exhibiting pulverization effect by Y=a×X+b×X+c, where Xis Gieseler maximum fluidity (ddpm), Xis total expansion ratio of a fraction with the predetermined opening or less and a, b and c are constants, a process D for determining a single coal having at least the largest value Y and a process for pulverizing the single coal which is determined to have at least the largest value Y.SELECTED DRAWING: Figure 1
【課題】 特殊な装置を必要とせず、簡便な方法で粉砕粒度を適正化して、製造されるコークスの強度を高強度化することが可能なコークスの製造方法を提供すること。【解決手段】 複数種の単味炭を配合して得られる装入炭を乾留することによりコークスを製造するコークスの製造方法であって、所定の目開きの篩で各単味炭を篩分けする工程A、工程Aにより篩分けされた所定粒度以下のフラクションの全膨張率を、ジラトメーターにより測定する工程B、粉砕効果を示す値Yを、Y=a×X1+b×X2+cにより算出する工程C(ただし、X1は、ギーセラー最高流動度(ddpm)であり、X2は、所定粒度以下のフラクションの全膨張率であり、a、b及びcは定数である。)、少なくとも値Yの一番大きい単味炭を決定する工程D、及び、少なくとも値Yが一番大きいと決定された単味炭を粉砕する工程Eを含むコークスの製造方法。【選択図】 図1 |
