论述电渣技术在离心铸造转化炉管制造中的应用，对采用造渣和未采用造渣技术制造的炉管进行了比较。结果表明，采用造渣技术对防止炉管内壁氧化、提高内表面质量和消除疏松层效果显著 The application of electroslag technology in the manufacture of centrifugal cast reformer tubes is discussed. The furnace tubes made of slag and without slag making technology are compared. The results show that the use of slagging technology to prevent the oxidation of the inner wall of the furnace to improve the quality of the inner surface and eliminate the effect of loose layer significantly
