Pines de control.<\/a> Por lo general, est\u00e1n fabricadas con un material refractario, capaz de soportar la alta temperatura del metal fundido. El material tambi\u00e9n debe ser duro para resistir el desgaste en el extremo de la varilla, donde ejerce presi\u00f3n contra el asiento de la boquilla.<\/p>\n![\"Pasador](\"http:\/\/www.adtechamm.com\/wp-content\/uploads\/2018\/03\/20180302Alumina-Ceramic-Porcelain-Rod-Control-Pin.jpg\" "\\"Pasador")
<\/p>\n
Uno de los materiales m\u00e1s utilizados es la s\u00edlice fundida densa (DF\u2019S). Este material es bastante resistente y presenta buenas caracter\u00edsticas frente a los choques t\u00e9rmicos, pero la s\u00edlice se humedece y se ve atacada por el aluminio l\u00edquido, por lo que los pasadores de control fabricados con este material deben estar provistos de un recubrimiento protector antiadherente, por ejemplo, de nitruro de boro.
\nEste recubrimiento debe renovarse con frecuencia (por ejemplo, cada una o dos operaciones de vertido) y, por lo tanto, estos pasadores requieren un alto nivel de mantenimiento.<\/p>\n
Adem\u00e1s, aunque el DFS es bastante resistente, es propenso a agrietarse y estas grietas tienden a propagarse por el material durante su uso.
\nEsto puede provocar, con el tiempo, que parte del pasador de control se desprenda y obstruya el pico vertedor. Como medida de precauci\u00f3n, a veces se incrusta un alambre de acero inoxidable en el material DFS para garantizar que, incluso si el pasador de control se rompe, la parte rota pueda retirarse del pico vertedor.
\nOtra desventaja de los pines de control fabricados en DFS es que suelen tener una elevada capacidad t\u00e9rmica y deben precalentarse antes de iniciar la operaci\u00f3n de colada, para que alcancen o se acerquen a la temperatura del metal fundido.
\nEsto aumenta considerablemente la complejidad de la operaci\u00f3n de colada y conlleva el riesgo de que se produzca un accidente grave al trasladar el pasador de control caliente desde el horno de precalentamiento hasta la boquilla. S-P550762c.wpd, 7 de octubre de 2004.
\nSi el pasador de control no se precalienta, el metal fundido puede solidificarse al entrar en contacto con \u00e9l, bloqueando as\u00ed la boquilla.<\/p>","protected":false},"excerpt":{"rendered":"
