摘 要：<正> The low Ni steel modified hy rare earth（3Cr24NiTSiN with an addition of 0.3% Ce）for furnace roller hasbeen developed.Due to the RE（rare earth）addition,a dense oxide film is formed on the steel surface at hightemperature,and the oxidation rate is decreased.This film has so good adhesion to the matrix that it will not bepeeled off easily.The RE modified steel has excellent oxidation resistance and thermal strength even if beingused continuously for a long period at high temperature.This steel roller has a service life of about 4 years com-parable to high Ni steel ones,so the low Ni steel can replace high Ni steel to make furnace roller.The Ni contentof this material can be reduced by 65% in comparison with Cr25Ni20Si2 steel,The low Ni steel has better pro-eessing properties including melting,casting and working properties than that of high Ni ones.
