Abstract

UN PROCESO RAPIDO Y ECONOMICO PARA PREPARAR, SIN RESIDUOS NUCLEOS DE TRANSFORMADORES PERFILADOS COMO E-I O U-I QUE CONSTAN DE LAMINADOS (1,2-9,10) QUE SE APILAN DIRECTAMENTE DURANTE EL PUNZONADO Y ESTAN UNIDOS PERMANENTEMENTE MEDIANTE ZONAS PERFORADAS (5,5''). CADA EXTREMO LIBRE DE LOS LAMINADOS PERFILADOS E(1) O U(9) TIENE UN PERFIL, UNA JUNTA DE REMACHE QUE EMPAREJA EL PERFIL (4,4'') DEL LAMINADO EN FRENTE DE EL (2,10) PARA PERMITIR SU FIJACION RIGIDA. LOS LAMINADOS SE OBTIENEN A PARTIR DE UNA BANDA DE ACERO (11) UTILIZANDO UNA MAQUINA CORTADORA DE SUMINISTRO DISCONTINUO DESDE UNA ESTACION DE PROCESAMIENTO A LA SIGUIENTE.
