感应电炉的筑炉是复杂的工序,没有正确详实的工艺规范指导,全面掌握这项技术难度较大。用于铸铁的中小型容量感应电炉炉衬(坩埚),大部分采用炉内打结法。筑炉工作的优劣最终体现在坩埚的寿命,许多企业由于选用不达标的筑炉耐火材料,筑炉工艺不完善,操作不熟练等原因,致使坩埚寿命不长,每次筑炉后开炉30~50炉,就面临漏炉、穿底的危险。本文总结了适用于中小型感应电
Induction furnace building furnace is a complex process, there is no correct and detailed guidance of the process specifications, a comprehensive grasp of the technology more difficult. For small and medium sized cast iron induction furnace lining (crucible), most of the knotted furnace method. The pros and cons of the furnace construction is ultimately reflected in the life of the crucible, many enterprises due to the selection of substandard furnace refractory material, building furnace imperfections, unskilled operation and other reasons, resulting in crucible life is not long, open after each furnace 30 to 50 furnaces, facing the leak furnace, wearing the end of the danger. This article summarizes the application of small and medium sized inductive electricity
