| 摘 要： | 针对炼钢厂炼钢至连铸全流程,建立了钢包热循环过程钢包热状态跟踪模型,并将包衬温度实测和数值模拟相结合,利用传热反问题修正模型,提高模型的准确度.利用钢包热状态跟踪模型分析了新砌钢包烘烤预热时间、空包时间、离线烘烤时间和包衬侵蚀等因素对钢水温度的影响规律.结果表明:新砌钢包烘烤预热时间从480min增加到780min,可使新包第一次热循环中钢水总温降减少15.6℃;空包时间为540min时,钢水温降比正常周转包增加14.6℃;空包时间越长,离线烘烤减少钢水温降的效果越明显;当空包时间为540min时,进行240min离线烘烤,可使钢水总温降减少11.0℃;包衬侵蚀可使钢水总温降最大增加9.3℃.

| Abstract: | A ladle thermal tracking model was established for the whole steel working process,from steelmaking to continue casting.The ladle thermal tracking model was modified by using the inverse heat transfer problem,which combined ladle thermal status testing and ladle heat transfer numerical simulation.With the ladle thermal tracking model some factors influencing molten steel temperature were analyzed such as new ladle preheating time,cooling time,off-line preheating time and the wear of the work wall and bottom... |
