Abstract

"MéTODO PARA REMOçãO DE CONCRETO REFRATáRIO COM USO DE EXPLOSIVOS EM EQUIPAMENTOS INDUSTRIAIS". Patente de Privilégio de Invenção para um método de remoção de concreto refratário com uso de explosivos em equipamentos industriais que consiste em executar furos 3 em concreto refratário 2 que está fixado por grampos 10 em uma estrutura metálica 1, os furos 3 citados são carregados com carga explosiva 4 e são devidamente confinados 5, posteriormente são interligados por meio de tiras de cordel detonante 6 e são feitos nós 7 para unir essas tiras de cordel detonante 6 as linhas tronco de cordel 11, que podem conter retardos 8 em locais apropriados, formando o conjunto denominado malha explosiva. Após esta montagem a malha explosiva 12 é acionanada mediante o uso de um iniciador 9 e ocorre a remoção do concreto refratário 2."METHOD FOR REMOVING REFRACTORY CONCRETE WITH THE USE OF EXPLOSIVES IN INDUSTRIAL EQUIPMENT". Patent of Privilege of Invention for a method of removing refractory concrete with the use of explosives in industrial equipment that consists of making holes 3 in refractory concrete 2 that is fixed by clamps 10 in a metallic structure 1, the mentioned holes 3 are loaded with load explosive 4 and are duly confined 5, later they are interconnected by means of detonating cord strips 6 and knots 7 are made to join these detonating cord strips 6 to cord trunk lines 11, which may contain delays 8 in appropriate places, forming the explosive mesh. After this assembly, the explosive mesh 12 is activated using an initiator 9 and the refractory concrete 2 is removed.
