1 2 首钢国际工程公司拥有多项铁水预处理优势技术, 能够结合客户的个性化需求, 在高炉铁水沟、 铁水运输线、 铁水倒罐站、炼钢厂房内等多个不同位置,在铁水包、鱼雷罐、专用炉等多个不同反应容器内,完成铁水脱硫、 脱硅、脱锰、脱磷处理,实现 高效、高质、低成本、节能、环保 的铁水供应. BSIET has plenty of advanced technologies in hot metal pretreatment, which meet the clients'

individualized requirements of desulphurization, desilication, demanganization and dephosphorization on different positions of iron runner, hot metal transportation line, hot metal re-ladle station and steel-making house and in different reaction vessels of hot metal ladle, torpedo ladle and special furnace etc, realizing a high ef?ciency, high quality, low cost, energy saving , environmentally friendly hot metal supply. 铁水 KR 脱硫 Hot metal KR desulphurization 铁水脱磷 Hot metal dephosphorization 鱼雷罐铁水脱硫 Hot metal desulphurization in torpedo ladle 铁水沟铁水脱硫 Hot metal desulphurization in iron runner 优势工艺技术 Advanced technologies of process 单吹颗粒镁脱硫工艺 Desulphurization by injection of particle Mg only 颗粒镁喷吹脱硫工艺具有设备简单、投资省、渣量少、铁损小、处理时间短、温降低、脱硫剂消耗低、运 行成本低等优势. 首钢国际工程公司在自主研发关键工艺技术的基础上, 形成了不同形式的单吹颗粒镁脱硫工艺. The desulphutization by injection of particle Mg only has advantages of simple equipment, less investment, less slag, less iron loss, shorter processing time, less temperature drop, less consumption of desulphurizing agent and lower operation cost. BSIET has developed different forms of desulphurization by injection of particle Mg only based on the independently developed key technology. 铁水线上在线喷吹捞渣脱硫方式 该工艺能够最大限度地节约主厂房占地面积、加快处理节奏,具有良好的经济和社会效益. 技术特点 将横移车与喷枪升降装置相结合,一台喷枪横移车对应两个喷吹脱硫工位,缩短处理周期,减少铁水温 降,节省设备投资 采用捞渣技术,通过捞渣设备的旋转功能,实现一台捞渣机对应两个工位的工艺操作,节省设备投资 在铁水车上进行脱硫,无需配置大天车吊运铁水包,节省设备投资 采用防溅罩,减少喷溅对设备的损坏 保证横移车精确对位后自动锁死(精度达到±50mm),防止横移车在脱硫过程中发生跑偏 Desulphurization by on-line injection and slag skimming in hot metal line This technology can save as much as possible the occupied land area of main shop building, speed up processing rhythm, realizing a good economic and social bene?t. Technical features The traversing car is combined with lance lifting device, and each traversing car has two desulphurization injection positions, thus reducing the treatment cycle, reducing the temperature drop of hot metal and saving equipment investment Slag skimming process can use one skimmer with two working positions through the revolving function of the skimmer, thus saving equipment investment Desulphurization is conducted on the hot metal car, so there'
