INTENSITY ESTIMATION METHOD OF COKE AND MANUFACTURING METHOD OF COKE

PROBLEM TO BE SOLVED: To provide an estimation method of drum intensity DI with more excellent accuracy.SOLUTION: There is provided an intensity estimation method of coke obtained by dry distilling blended coal obtained by blending a plurality of kinds of single coals and a binding material, including a process A for obtaining index Iand index Iof each blending single coal and binding material, a process B for calculating dHIcorresponding to difference of the index Iand the index Iof the blended coal before blending the binding material based on the index I, the index Ia and blended percentage of each single coal and binding material, a process C for estimating drum intensity DI of the blended coal after blending the binding material based on dHI, index dHIwhich is difference of index Iand index Iof the binding material and blended ratio of the binding material.SELECTED DRAWING: None 【課題】 より精度のよいドラム強度ＤＩの推定方法を提供すること。【解決手段】 複数種の単味炭と粘結材とを配合して得られる配合炭を乾留することにより得られるコークスの強度推定方法であって、配合する各単味炭及び粘結材の指標ＩＨ／Ｃ及び指標ＩＯ／Ｃを得る工程Ａ、指標ＩＨ／Ｃ及び指標ＩＯ／Ｃと、各単味炭及び粘結材の配合割合とに基づいて、粘結材配合前の配合炭の指標ＩＨ／Ｃと指標ＩＯ／Ｃとの差に相当するｄＨＩ０を求める工程Ｂ、及び、ｄＨＩ０と、粘結材の指標ＩＨ／Ｃと指標ＩＯ／Ｃとの差である指標ｄＨＩａと、粘結材の配合割合とに基づいて、粘結材配合後の配合炭のドラム強度ＤＩを推定する工程Ｃを含むコークスの強度推定方法。【選択図】 なし
