Abstract

Procedimiento para la fabricación de cuerpos trituradores forjados en acero, con alta proporción en carbono y estructura martensítica finamente dividida obtenida en el núcleo, que comprenden una proporción en carburos de 2 a 6 % en peso, en forma de carburos mixtos de hierro y de cromo de tipo (Fe, Cr)3 C; caracterizado porque se lleva a una temperatura del orden de 900 a 1.100ºC una barra u ovoides de acero que proceden de colada o de mezcla y que tienen la composición deseada; se procede eventualmente al corte en trozos de la barra a la mencionada temperatura; y se efectúa el forjado de los trozos a dicha temperatura de 900 a 1.100ºC.
