太原钢铁公司于1987年4月在峨口矿动工兴建球团竖炉,同年12月28日竣工投产,且半年即达到设计能力。在冶金矿山建设球团竖炉不仅缓和了太钢厂区拥挤、环保容量小的矛盾,而且还使水电资源紧张问题得到改善。矿山生产球团是产品延伸提高经济效益的重要途径,从而开创了矿山生产商品球团的先例。1988年生产球团矿20万吨。球团矿化学成分如下(%):TFe FeO SiO _2 Al_2O_3 CaO MgO62.58 0.90 8.49 0.43 0.389 0.22MnO P S 烧损CaO/SiO_20.10 0.019 0.004 0.01 0.05球团矿抗压强度为:平均值3162N/个;>1960N/个83.30%;<980N/个3.30%1200m~3高炉配加球团矿冶炼试验从1988年3月开始,到7月底结束,紧接着便转为正常工业生产。在试验期全厂球团矿配比为13.4%,增产4.8%,节焦0.9%,取得
Taiyuan Iron and Steel Company in April 1987 Emeikou started construction pellet shaft furnace, the same year on December 28 completed and put into production, and six months to reach the design capacity. The construction of pellet shaft furnaces in metallurgical mines not only alleviates the conflict in TACCO’s area of congestion and environmental protection, but also improves the shortage of hydropower resources. Mine production of pellets is an important way to extend the economic benefits of products, thus creating a precedent for the production of pellets in the mine. In 1988, it produced 200,000 tons of pellets. The chemical composition of the pellets is as follows: (%): TFe FeO SiO 2 Al 2 O 3 CaO MgO 62.58 0.90 8.49 0.43 0.389 0.22MnO PS Burn CaO / SiO_20.10 0.019 0.004 0.01 0.05 Pellets compressive strength: average 3162N / ;> 1960N / a 83.30%; <980N / a 3.30% 1200m ~ 3 blast furnace with pellet smelting test began in March 1988 until the end of July, followed by the normal industrial production. In the trial period the whole plant pellet ratio was 13.4%, an increase of 4.8%, the festival coke 0.9%, made
