Abstract:
(EN) The purpose of the present invention is to provide a pearlite rail that has little softening in a welding heat affected zone, high hardness, and high ductility, a flash butt welding method for a pearlite rail, and a method for manufacturing a pearlite rail. In mass percentage, the pearlite rail contains 0.70 - 1.0% C, 0.1 - 1.5% Si, 0.01 - 1.5% Mn, 0.001 - 0.035% P, 0.0005 - 0.030% S, and 0.1 - 2.0% Cr, with the remainder being Fe and inevitable impurities, and the γ + θ temperature range is 100°C or less.
(FR) La présente invention concerne un rail en perlite qui présente peu d'adoucissement dans une zone touchée par la chaleur de soudage, une haute dureté et une haute ductilité, un procédé de soudage en bout par étincelage destiné à un rail en perlite et un procédé de fabrication d'un rail en perlite. En pourcentage massique, le rail en perlite contient 0,70-1,0 % de C, 0,1-1,5 % de Si, 0,01-1,5 % de Mn, 0,001-0,035 % de P, 0,0005-0,030 % de S et 0,1-2,0 % de Cr, le reste étant du Fe et des impuretés inévitables, et la plage de température γ + θ étant de 100°C ou inférieure.
(JA)  溶接熱影響部の軟化が少ない高硬度、かつ、高延靱性のパーライトレール、パーライトレールのフラッシュバット溶接方法、およびパーライトレールの製造方法を提供することを目的として、質量パーセントで、C:0.70~1.0%、Si:0.1~1.5%、Mn:0.01~1.5%、P:0.001~0.035%、S:0.0005~0.030%、Cr:0.1~2.0%を含有し、残部がFeおよび不可避的不純物であって、γ+θ温度範囲が100℃以下であるパーライトレールとする。
