CONTAINER CRANE WHEEL STEEL, WHEEL AND PREPARATION METHOD THEREFOR

Container crane wheel steel, a wheel and a preparation method therefor. By means of designing chemical components of the container crane wheel steel and adding a post-forging preparatory heat treatment between forging forming and rough machining, a container crane wheel that has good robustness and an excellent surface hardening layer is prepared. The wheel tread hardness thereof can be above HRC55, the effective hardening layer depth is greater than or equal to 15mm, and the hardness at a depth of 15mm below the wheel tread is greater than or equal to HRC35, so that the container crane wheel has the advantages of high surface hardness, a deep effective hardening layer and good internal toughness. The service life of the container crane wheel can be increased by more than 50% compared to conventional 45# and 55# carbon steel wheels. La présente invention concerne un acier pour roue de grue à conteneurs, une roue et un procédé de préparation associé. Au moyen de la conception de composants chimiques de l'acier
