Abstract

"PROCESSO DE FABRICAçãO DE PUNHO PARA ACOPLAMENTO DE HASTE PERFURADORA EM MANDRIL DE PERFURADORES DE FURO DE CORRIDA EM ALTOS-FORNOS". A invenção propõe um processo para fabricação do punho (6) de acoplamento da haste perfuradora (5) no mandril (3) do perfurador (2). O processo da invenção prevê a fabricação do punho (6) por conformação dos tubos (10) e (12) com diâmetros internos (Di) e seção transversal compatíveis com a forma da seção transversal e dimensões do diâmetro externo da haste perfuradora (5). sendo em seguida seccionado em seções (Cn) e (An) concretizando, respectivamente, a castanha de travamento (7) e o anel alongado (9), que posteriormente serão unidos por solda para formarem o punho (6). Os punhos (6) produzidos pelo processo da invenção conferem vantagens adicionais de redução de tempo e de custo em sua etapa de fabricação. Já na etapa de aplicação, atuando como componente do conjunto perfuratriz do furo de corrida do alto-forno, garante maior segurança e estabilidade operacional.
