摘要
包钢在高炉设计中,始终以“高炉长寿”为主题。为适应白云鄂博特殊矿冶炼,高炉炉型逐渐向矮胖型发展,炉身中部以下从炭砖砌筑过渡到微孔铝炭砖砌筑,将厚炉衬逐步改为薄壁炉衬,炉缸部位采用国产大块炭砖和高导热的UCAR炭砖,由低导热炉缸改为了高导热炉缸。重视施工质量,优化冷却装置与介质参数,坚持精料方针,控制入炉有害元素含量,保持炉缸活跃,强化炉役后期的技术和管理措施,形成可确保高炉稳定顺行、高产低耗和高炉一代寿命达到15年以上的生产技术管理体系。
In the design of blast furnaces in Baotou Steel,“long campaign of blast furnace”is always the subject.In order to adapt to the smelting of special ore in Bayan Obo,blast furnace profile is gradually developed towards low shaft,the part below middle of blast furnace shaft is constructed with microporous alumina carbon brick instead of carbon brick,thick furnace lining is gradually changed to thin skinned lining,furnace hearth is with domestic large carbon brick and high heat-conducting UCAR carbon brick as well as low heat-conducting furnace hearth is changed to high heat-conducting furnace hearth.The production technology management system that could ensure stable and smooth operations of blast furnace,high output and low consumption as well as campaign of blast furnace to be over 15 years is formulated through paying attention to construction quality,optimizing cooling equipment and medium parameters,adhering to the principle of beneficiated burden material,controlling contents of harmful elements as fired,keeping furnace hearth active as well as strengthening technologies and management measures at later stage of campaign.
