摘要：

以稳定焦炭粒度为核心，梳理首钢京唐公司7.63 m焦炉炼焦过程及焦炭粒度数据，分析研究配煤质量、炭化时间、熄焦工艺、焦炭转运及筛分工艺与焦炭粒度的对应关系。通过优化焦炭转运流程，控制焦仓料位不低于3 m；并重视配煤水分稳定性，控制波动在±0.3%范围内；尤其重视筛分工艺过程的有效性管理，提升焦炭粒度稳定性。

关键词: 7.63 m焦炉, 焦炭粒度, 配煤质量, 炭化时间, 焦炭转运, 筛分工艺

Abstract:

Based on the principle of stabilizing coke size,this paper studies the coking process and coke size of 7.63 m coke oven in Shougang Jingtang company,analyzes the factors affecting the coke grain size,such as coal blending quality,carbonization time,quenching process,coke transfer and coke screening.By optimizing coke transferring,the material level of coke bin is controlled at least 3 m;special attention is paid to the moisture stability in coal blending,within the range of ±0.3%,in particular to the effective management of screening process to improve the stability of coke grain size.

Key words: 7.63 m coke oven, Coke grain size, Coal blending quality, Carbonization time, Coke transferring, Screening process
