| Operation system and technology of BF during iron making process is one of the key projects in the current iron and steel making industry. Operation system and technology in the BF is one of the most important parameters which represents the technical and economical index lever as well as relate to the sustainable development of the BF for iron making, under conditions of the raw materials and equip certain level, the economic index sign of technique towards BF of the reasonable's operation system and technique rising the function of the decision. This thesis deals with by studying general development situation of operation system and operation technology of blast-furnace process at home and abroad, considering producing situation of blast-furnace in Jisco, based on a large amount of detailed and accurate production datas, comparative and analytic experiments of operation system and method in each blast-furnace phase in Jisco are described in the article. Through continous optimization and practice, appropriate operation system and technology of each item suited for Jisco blast-fuenace current situation have been searched out, with which tremendous decreasing of coke and energy has been achieved in the BF of the Jiuquan Iron and Steel Cooperation in the last few years. Therefore, great economic profit has been obtained. Besides, The thesis also discuss that only by combining the best operation system and operation technology with fine material andhigh-performance equipment as well as personnel stuff and scientific management can we make optimum economic profit. |
