选用大同烟煤和高温煤沥青为原料,采用压块成型法制造煤质颗粒活性炭。
将洗涤后的滤渣烘干、破碎,然后与烟煤混合,以纸浆废液为粘结剂制成球团;
1·Therefore, the study on making use of high volatile bitumite is very important, and is also significant for solving thoroughly the techniques of injecting bitumite in blast furnace in our country.
因此研究高比例配加或全部使用高挥发份烟煤的安全喷吹技术是十分重要的,对解决我国高炉喷吹烟煤的技术制约问题具有重要的意义。
2·Previous study has showed that the factors affecting the bitumite explosiveness are various.
研究表明,影响烟煤爆炸性能的因素是多种多样的。
