Abstract

In the present work, coke is produced from batch with a high content (60–80%) of gas coal, in semiindustrial and industrial conditions. The influence of the following factors on the coke yield and quality is investigated: the coke oven’s wall temperature; the coking duration and rate; the final temperature at the center of the charge; and the content of gas coal in the batch. The quality of individual size classes (>80 mm to ≤5 mm) in the coke is assessed on the basis of technical analysis, the mechanical strength, the reactivity, the electrical resistivity, and the pore structure. A coke sorting system that incorporates mechanical treatment is proposed. By that means, three coke classes are obtained: >40, 10–40, and ≤10 mm. The potential steel-industry demand for such classes is assessed.

含气量高的批料的焦炭馏分的收率和质量

摘要

在目前的工作中，在半工业和工业条件下，焦炭是由含气量高（60-80％）的煤制成的。研究了以下因素对焦炭产量和质量的影响：焦炉的壁温；焦化时间和焦化率；装料中心的最终温度；以及批次中的气煤含量。根据技术分析，机械强度，反应性，电阻率和孔结构评估焦炭中单个尺寸等级（> 80 mm至≤5mm）的质量。提出了一种结合机械处理的焦炭分选系统。通过这种方式，获得了三种焦炭类别：> 40、10–40和≤10mm。评估了此类钢铁行业的潜在需求。
