Manufacturing method of carbonized blocks used for manufacturing isotropic graphite
Provided is a method for manufacturing carbonized blocks used for manufacturing isotropic graphite, comprising the following steps: mixing a first coke powder and a second coke powder having different particle sizes at a weight ratio of 1 : 0.8 to 1.2 and mixing binder pitch with the coke mixture powder; pressurizing and molding the mixed product; and carbonizing the molded body, wherein the average particle size (D50) of the first coke powder and the second coke powder is 3 to 7 ㎛ and 8 to 12 ㎛, respectively, and the content of binder pitch in the mixing step is 23 to 27 wt% with respect to 100 wt% of the total mixed product.
본 발명은 입도가 상이한 제1 코크스 분체 및 제2 코크스 분체를 1 : 0.8 내지 1.2의 중량비로 혼합한 코크스 혼합 분체와 바인더 피치를 혼련하는 단계; 혼련물을 가압 성형하는 단계; 및 성형체를 탄화하는 단계;를 포함하고, 제1 코크스 분체 및 제2 코크스 분체의 평균 입도(D50)는 각각 3 내지 7 ㎛ 및 8 내지 12 ㎛이고, 혼련하는 단계에서 바인더 피치의 함량은, 총 혼련물 100 중량%에 대하여 23 내지 27 중량%인, 등방 흑연 제조용 탄화 블록 제조방법을 제공한다.
