Abstract

Procedimiento para la regulación de una carburación de piezas al vacío, en un horno al vacío, en el cual se introduce como portador de carbono un gas de hidrocarburo, en el horno, caracterizado porque, como magnitud reguladora se utiliza una formación de niebla de hollín, de tal manera que se determina la aparición de niebla de hollín, que la adición de hidrocarburos se interrumpe total o parcialmente, al aparecer la niebla de hollín y que vuelve a reanudarse la adición de hidrocarburo, si ha remitido la formación de niebla de hollín.
