Abstract

La lance est constituée par un toron de fils d'acier 1 comportant un canal axial 2 et, de préférence, entouré d'une gaine souple formée par l'enroulement d'un ruban 3. Forage de trous dans les matériaux tels que le béton et plus généralement dans ceux qui forment avec les oxydes de fer un laitier fusible.
