对龙钢烟煤、泰和兰炭及二者以不同比例（兰炭加入比例分别为30％、40％、50％）混合的试样的爆炸性、着火点、灰熔点及可磨性指数进行研究。分析了5种方案试样的冶金性能和对高炉喷吹性能的影响。兰炭的加入，可以使煤的爆炸性减弱，着火点降低，可磨性指数提高，灰熔点略降。结果表明，泰和兰炭与龙钢烟煤以3∶7混合时效果最佳，可以获得更优良的冶金性能。
對龍鋼煙煤、泰和蘭炭及二者以不同比例（蘭炭加入比例分彆為30％、40％、50％）混閤的試樣的爆炸性、著火點、灰鎔點及可磨性指數進行研究。分析瞭5種方案試樣的冶金性能和對高爐噴吹性能的影響。蘭炭的加入，可以使煤的爆炸性減弱，著火點降低，可磨性指數提高，灰鎔點略降。結果錶明，泰和蘭炭與龍鋼煙煤以3∶7混閤時效果最佳，可以穫得更優良的冶金性能。

Analyzing the Longgang bituminous coal , semi-coke and two in different proportion ( semi-coke join proportion are 30%, 40%, 50%) mixed samples of explosibility , ignition, ash melting point and index .The metallurgical properties of five kinds of solution sample were studied , and the af-fect on the performance of blast furnace injection was studied .The results show that through the addi-tion of semi-coke, the coal explosibility is weakened , ignition temperature is decreased , grindability index is increased , and ash melting point is lowered slightly .Moreover when mixed semi -coke with Longgang bituminous coal to 3∶7 , the effect is best , can obtain more excellent metallurgical proper-ties.
