摘　　要：淮钢"十五"技改一期工程共建造6座卡鲁金顶燃式热风炉,一列式布置,热风炉分为蓄热室大墙、拱顶、预燃室,选用普通的耐火材料,采用独立的拱顶、预燃室支架支撑结构和高风温长寿命技术,具有高效、环保、体积小、造价低、风温高、寿命长的特点。实际应用表明,总的换炉时间缩短到8min,日平均最高入炉风温1250℃,平均入炉风温高于1200℃。Six Kalugin top-combustion stoves were built in Huaigang at the first stage of the technical project modification during the tenth-five-year plan and their arrangement is in one line. The hot blast stove is composed of the big wall of regenerator, arc roof and pre-combustion chamfer. The common refractory and technologies of independent arc roof, pre-combustion chamfer supported by the structure, high blast temperature and long working lifetime were utilized. So the hot blast stove has the following advantages： high efiiciency, environmental protection, small volume, low cost, high blast temperature and long working lifetime. It shows in the practical production that the total time of heat changing is reduced to 8 min. The highest input blast temperature of daily average is 1 250℃ and the average input blast temperature is higher than 1 200 ℃.
