太钢7.63m焦炉焦炭强度预测研究

太钢(集团)公司为配套4 350m3高炉生产高强度的焦炭,从德国引进了目前国内炭化室最高的7.63m焦炉。为了保证焦炉投产后生产的焦炭强度能满足高炉的生产要求,进行了大焦炉配煤技术研究。首先选择了11个单种煤试样在实验室进行配煤研究,并将研究结果的配煤方案在4.3m焦炉上进行工业性试验,根据工业性试验结果,对7.63m焦炉焦炭强度进行预测。实践证明,7.63m焦炉投产后,焦炭强度与预测值基本相符,可满足高炉生产要求。

Study on the Strength Forecast of the Coke from 7.63m Coke Oven

In order to meet the high strength coke demands of the newly built 4 350m3 BF,a set of 7.63m coke oven was imported from Germany to Taiyuan Iron and Steel Co.(TISCO).Research work on the proportion of coal blending was carried out in advance to produce high quality coke.Industrial trial production was carried out on the 4.3m coke oven on the basis of the laboratory test regarding to 11different coking coals.This paper presents the whole process of the industrial trial production and based on the test result,the coke strength from the 7.63m coke oven was predicted.The production practice had indicated that the coke quality from 7.63m coke oven complied with the forecast results and satisfied the requirements of 4 350m3 BF.
