Abstract

L'invention concerne un procédé d'abattage du garnissage d'un four destiné aux fontes de haute température, telles que des fontes de verre ou de métaL Les garnissages de ce type sont souvent constitués par une matière qui forme, près de la paroi du four, une couche pulvérulente et qui, en dehors de cette couche, est constituée par une couche d'une masse extérieure très dure et difficile à travailler. Pour abattre un tel garnissage on enlève d'abord, selon cette invention, de la matière de la couche intérieure, et ensuite on casse la couche extérieure dans les zones d'où la matière de la couche intérieure a été enlevée. Ainsi, on découvre la couche extérieure dure et travaille cette couche sans que la matière de la couche intérieure ne serve de base.
