Abstract

이론적으로 유도된 코크스강도와 코크스화성의 수학적 관계식;
S = S+k1(∂2S/∂(MF)2)∑Fi(MF)-(MFi)2Pi 에서
H=∑Fi(MF)-(MFi)2Pi 라 두면, H의 값을 원료탄의 입도분포 조정에 의해 최소화함으로써 코크스강도를 향상시킬 수 있음을 알 수 있다. 이 이론을 기초로 장입탄의 입도조정에 의한 새로운 코크스 강도향상 방법이 제안되었다.
실제로 H값을 줄이도록 입도조정된 장입탄으로부터 제조된 코크스의 강도시험을 통하여 제안된 방법의 타당성이 입증되었다.
In order to improve the coke strength resulting from the coke manufacturing process of the bituminous coals, the particle size distribution and blending ratios of the various raw coals having different coking strengths were adjusted before charging the blended sample coals into cokes oven. The average strength,
