Como todos sabemos, los ra\u00edles de ferrocarril se fabrican con determinadas longitudes, como 12,5 m, 25 m, y los alargados de 50 m a 100 m. Independientemente de la longitud de la v\u00eda f\u00e9rrea, es necesario unirlas de extremo a extremo para formar una v\u00eda f\u00e9rrea continua. Esto se puede realizar mediante uniones de rieles (barras de uni\u00f3n) o m\u00e9todos de soldadura. En este momento, nos centramos en la soldadura de v\u00edas f\u00e9rreas.\u00a0<\/span><\/p><\/div>

Existen cuatro m\u00e9todos habituales para soldar\u00a0v\u00edas del tren<\/a>. Se trata de la soldadura a tope por chispa, la soldadura por gas a presi\u00f3n, la soldadura por arco cerrado y la soldadura por termita. \u00bfCu\u00e1les son las diferencias entre estos m\u00e9todos? Hemos resumido las aplicaciones en diferentes condiciones de construcci\u00f3n para que pueda compararlas.<\/p>

En una palabra, la soldadura por termita es el m\u00e9todo m\u00e1s utilizado para soldar v\u00edas de ferrocarril. Es f\u00e1cil de utilizar y no necesita energ\u00eda el\u00e9ctrica. El equipo y los materiales necesarios son f\u00e1ciles de conseguir.\u00a0<\/p>

El principio de la termosoldadura ferroviaria<\/h2>

La soldadura por termita de ra\u00edles es un m\u00e9todo de soldadura que utiliza el calor de la reacci\u00f3n qu\u00edmica como fuente de calor. Al soldar, los extremos de los dos ra\u00edles se fijan previamente en el molde y, a continuaci\u00f3n, la mezcla de polvo de aluminio y polvo de \u00f3xido de hierro (denominada termita) se calienta en el crisol. Se produce una reacci\u00f3n exot\u00e9rmica que produce metal l\u00edquido (hierro) y escoria fundida que se inyectan en el molde. El metal l\u00edquido fluye hacia los huecos de las juntas para formar el metal de soldadura, mientras que la escoria flota en la superficie. Para ajustar la temperatura de la masa fundida y la composici\u00f3n qu\u00edmica del metal de soldadura, a menudo se a\u00f1aden a la termita aditivos y aleaciones adecuados.<\/p>

El proceso de soldadura de ra\u00edles de ferrocarril<\/h2>
\"proceso<\/figure><\/div><\/div><\/div>

\u00a0<\/p>

  1. Preparaci\u00f3n<\/span><\/li><\/ol>

    Preparaci\u00f3n de equipos y material auxiliar<\/span>
    Material de consumo: termita, molde de arena, crisol, lodo de sellado, cerillas de alta temperatura, muela abrasiva, propano, ox\u00edgeno, manguera.
    Equipo auxiliar: molde, bandeja de escoria, horquilla de crisol, fijaci\u00f3n de molde de arena, tapa de molde de arena, regla inclinada de 1 m, term\u00f3metro de carril, dispositivo de sujeci\u00f3n, palanca, bastidor de precalentamiento, cu\u00f1a de acero.
    Maquinaria auxiliar: sierra de carril, pulidora, amoladora port\u00e1til, etc.<\/p>

    Preparaci\u00f3n de la v\u00eda f\u00e9rrea<\/span>
    Descargue los 2-4 pares de\u00a0fijaciones de carril<\/a>\u00a0a ambos lados del extremo de soldadura.<\/p>

    \"equipos<\/figure><\/div>
    1. Limpieza y secado del extremo del ra\u00edl<\/span>
      Utilice la\u00a0      trituradora port\u00e1til<\/a>\u00a0para eliminar el \u00f3xido y descontaminar el extremo del carril. Aseg\u00farese de que la cara de los extremos de carril a soldar est\u00e9 seca y limpia.<\/li>
    2. Alineaci\u00f3n del extremo del carril<\/span>
      La anchura entre las caras de los extremos de los ra\u00edles debe ser de 27 mm a 30 m. Se requiere la alineaci\u00f3n vertical y horizontal de la cabeza del carril, el alma del carril y la base del carril.<\/li>
    3. Instalaci\u00f3n de luminarias<\/span>
      La luminaria debe instalarse en direcci\u00f3n contraria al viento.<\/li>
    4. Instalaci\u00f3n de moldes de arena<\/span>
      El orificio de vertido est\u00e1 ligeramente recortado para evitar que las part\u00edculas de arena se desprendan durante el precalentamiento y el vertido, lo que producir\u00eda escoria de soldadura.
      Instale primero la placa inferior, luego instale el molde lateral y, por \u00faltimo, utilice la abrazadera para fijar el molde de arena.<\/li>
    5. Sellado<\/span>
      Aplique lodo sellador a la salida del molde de arena y a la rosca del accesorio para que el molde de arena y el riel queden bien sellados.<\/li>
    6. Precalentamiento<\/span>
      En primer lugar, regular la presi\u00f3n de trabajo del propano y el ox\u00edgeno. En segundo lugar, instale el calentador en el soporte, ajuste la boquilla al centro del molde de arena y coloque el tap\u00f3n de derivaci\u00f3n en el borde del molde de arena, retire el calentador del soporte y encienda la boquilla. En tercer lugar, regule la presi\u00f3n y la proporci\u00f3n de mezcla de propano y ox\u00edgeno para obtener la mejor llama. Por \u00faltimo, precalentar durante 5 minutos.<\/li>
    7. Instalaci\u00f3n del crisol<\/span>
      Este paso se prepara al mismo tiempo que el precalentamiento. Se mezcla la termita uniformemente y se vierte en el crisol. Introduzca la cerilla de alta temperatura y, a continuaci\u00f3n, tape el crisol.<\/li>
    8. Encendido<\/span>
      Coloque el crisol en el molde de arena justo despu\u00e9s de terminar el precalentamiento. Verifique la posici\u00f3n y encienda la cerilla r\u00e1pidamente.<\/li>
    9. Reacci\u00f3n termita<\/span>
      Observe la reacci\u00f3n qu\u00edmica. Cuando aparece la llama abierta, es el momento de inicio de la reacci\u00f3n termita. En cuanto la llama se apaga, la reacci\u00f3n qu\u00edmica se detiene. Normalmente, el tiempo de reacci\u00f3n de la termita es de 8-15 segundos.<\/li>
    10. Desmoldeo<\/span>
      Retire el molde de arena y la bandeja de escoria 5 minutos despu\u00e9s de verter el hierro fundido.<\/li>
    11. Cortar el exceso de termita<\/span>
      Corta la termita sobrante y dobla las que sobresalen a ambos lados de la base del ra\u00edl.<\/li>
    12. Rectificado<\/span>
      Este es el paso final de la soldadura de ra\u00edles de ferrocarril. Esto es para hacer que la superficie de los carriles unidos plana y lisa.<\/li><\/ol>

      Una vez finalizados los 13 pasos, comprueba las juntas de soldadura para asegurarte de que cumplen las normas. Restaura las v\u00edas del tren a su lugar original. Adem\u00e1s, a\u00fan queda trabajo de limpieza por hacer. Los trabajadores tienen que retirar el polvo, la escoria, la chatarra, el molde de arena y el crisol.<\/p><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
