对国内某钢铁厂800m3高炉出铁场进行改造设计:主要包括出铁场平坦化、单出铁场扩建至双矩形出铁场、风口平台改造、炉前设备升级、出铁场除尘改造。改造后的双矩形出铁场平整光洁,除尘效果显著,使炉前作业更加便利,炉前环境明显改善。投产后的生产实践表明,本次出铁场改造可高效处理渣铁,明显减轻工人劳动强度,改善出铁场环境,为高炉高产、稳产、长寿提供了可靠保证,达到了设计的预期目标。
The reconstruction design for the 800m3 blast furnace yard in a certain steel plant in China includes the following aspects: flattening the tapping yard, expanding the single tapping yard to the double-tapping tapping yard, renovating the platform of the tuyere, upgrading the front of the furnace and removing the dust in the iron yard. After the transformation of the double rectangular tundish smooth and clean, dust removal effect is significant, so that more convenient operation of the furnace, the furnace environment was significantly improved. Production practice after commissioning shows that the ironworks retrofitting can effectively treat slag and iron, significantly reduce labor intensity and improve the environment of the ironworks, provide a reliable guarantee for high yield, stable production and long life of the blast furnace, and achieve the expected design goals.
