山东地区1/3焦煤容惰能力研究

Study on the Inert-tolerant Capacity of the 1/3 Coking Coal from Shandong Area

通过引用黏结指数测试法,对山东地区1/3焦煤与气煤、气肥煤和其他地区1/3焦煤的容惰能力进行比较。结果表明,炼焦煤的容惰能力不仅与变质程度,也与工艺性质相关;在本实验分析煤样中,新汶气肥煤容惰能力最强,黄陵气煤容惰能力最差,山东付村1/3焦煤的容惰能力比其他地区高G值1/3焦煤微弱,山东蒋庄、润峰1/3焦煤的容惰能力比河市坝等低G值1/3焦煤弱,但高于气煤。

The method for determination of caking index is used in this paper to make a comparison of different inert-tolerant capacities of gas coal,gas-fat coal and 1/3 coking coal from Shan Dong area and the 1/3 coking coal from other areas.The results show that inert-tolerant capacity of coals is related to the metamorphism and the property of coking coal.The inert-tolerant capacity of gas-fat coal is the biggest,that of 1/3 cokingcoal from Fucun Mine in Shandong was smaller than that of the 1/3 coking coals havin...
