AIR-HARDENED MACHINE COMPONENTS
An example track shoe (118), cutting edge (120), or other component of a machine (100) is formed in a heated process, such as hot-rolling followed by air-hardening. The air-hardening process involves cooling the component by flowing air over the component (e.g., air cooling), such that the component...

| description | An example track shoe (118), cutting edge (120), or other component of a machine (100) is formed in a heated process, such as hot-rolling followed by air-hardening. The air-hardening process involves cooling the component by flowing air over the component (e.g., air cooling), such that the component is cooled at a controlled rate. During the air-cooling process, such as in the range of about 250º C to about 1100º C, the component may be machined, such as by shearing, punching, drilling, etc. The machining may form the final shape of the component. As the air-hardening process is completed, and the component approaches room temperature, the component may have at least 5% bainitic crystal composition, and as high as greater than 80% bainitic crystal composition, resulting in relatively high hardness and fracture toughness. The final track shoe (118) may have a hardness between about 40 HRC and 55 HRC.
Un exemple de l'invention concerne un patin de chenille (118), un bord de coupe (120) ou un autre composant d'une machine (100) qui est formé dans un processus chauffé, tel qu'un laminage à chaud, suivi d'un durcissement à l'air. Le procédé de durcissement à l'air comprend le refroidissement du composant par écoulement d'air sur le composant (par exemple un refroidissement par air), de sorte que le composant est refroidi à une vitesse régulée. Pendant le processus de refroidissement par air, par exemple dans la plage allant d'environ 250 °C à environ 1100°C, le composant peut être usiné, par exemple par cisaillement, poinçonnage, perçage, etc. L'usinage peut former la forme finale du composant. Au fur et à mesure que le processus de durcissement à l'air est achevé, et que le composant s'approche de la température ambiante, le composant peut avoir une composition de cristaux bainitiques d'au moins 5 %, voire de plus de 80 %, ce qui donne une dureté et une résistance à la rupture relativement élevées. Le sabot de chenille (118) final peut avoir une Dureté comprise entre environ 40 HRC et 55 HRC. |
