A method for removing refractory concrete by using explosives in industrial equipment

摘要

One describes a method for removing refractory concrete by using explosives in industrial equipment, which consists in making bores (3) in refractory concrete (2), which is fixed by clamps (10) onto a metallic structure (1); said bores (30) are loaded with an explosive load (4) and duly confined (5), and then interconnected by means of strips of detonating cord (6), and knots (7) are made to link these strips of detonating cord (6) to the trunk lines of string (11), which may contain delays (8) in appropriate places, the whole forming the so-called explosive network. After this mounting, the explosive network (12) is actuated by means of a starter (9), and the removal of the refractory concrete (2) takes place.
