摘　　要：传统的扇形包经过长时间工作,容易使高温铁液通过工作衬渗入到永久层后到达扇形包包壳,引起扇形包穿包事故,从而使扇形包寿命降低。详细阐述了一种长寿命扇形包的制作及应用,通过对扇形包进行改进,提升了扇形包的质量和使用寿命,控制了成本消耗,实现了扇形包等量铁液流出浇注,使包衬具有密实度高、强度高、孔隙率低和耐高温特点,经过实际生产验证,该扇形包还具有使用寿命长、抗渣能力好、容易清渣和抗侵蚀能力强等特点。The issue of traditional fan-shaped ladles experiencing reduced lifespan due to high-temperature molten iron penetrating the working lining,reaching the permanent layer,and eventually causing the ladle shell to wear through was introduced.A new long-life fan-shaped ladle was elaborated,with improvements in design that enhance its quality and longevity while controlling cost.This ladle ensured uniform molten iron flow during pouring and features high density,high strength,low porosity,and excellent high-temperature resistance.Production tests demonstrated that the ladle also had the characteristics of long service life,strong slag resistance,ease of slag removal,and high erosion resistance.
