Abstract

roda ferroviária. é fornecida uma roda ferroviária que é excelente em resistência em uma peça de cubo. uma roda ferroviária de acordo com a presente divulgação inclui uma peça de aro, uma peça de cubo com um furo passante e uma peça de rede. uma composição química da roda ferroviária consiste em, em% em massa, c: 0,60 a 0,80%, si: 1,00% ou menos, mn: 0,10 a 1,50%, p: 0,050% ou menos, s: 0,030% ou menos, e n: 0,0200% ou menos, sendo o restante fe e impurezas. em uma seção transversal da peça do cubo obtida quando a peça do cubo é cortada na direção do eixo central do furo passante ao longo de um plano incluindo um eixo central, quando regiões de 15 mm ¿ 15 mm definidas por uma pluralidade de segmentos de linha axiais paralelos a do eixo central e dispostos em um passo de 15 mm em uma direção radial da roda ferroviária a partir de uma superfície periférica interna do furo passante, e por uma pluralidade de segmentos de linha radiais perpendiculares ao eixo central e dispostos em um passo de 15 mm na direção do eixo central a partir de uma superfície da peça do cubo na qual uma abertura do furo passante é formada são definidas como regiões retangulares, a concentração média de c em cada região retangular na seção transversal da peça do cubo é inferior a 0,90% por massa.
