Abstract

LOS ARCOS PARASITOS QUE SE PRESENTAN CUANDO SE TRABAJA CON SOPLETES DE PLASMA, AFECTAN LA RENTABILIDAD Y PONEN EN PELIGRO PARTES IMPORTANTES DEL SOPLETE. LAS CONTRAMEDIDAS CONOCIDAS SOLO SON EFICACES EN PROPORCION LIMITADA. PROVEER DE REVESTIMIENTO AISLANTE ELECTRICO AL CANAL ANULAR ENTRE EL ELECTRODO Y LA TOBERA CONDUCTORA DE GAS PLASMA QUE RODEA AL ELECTRODO EN LA CARA INTERNA DE LA TOBERA, CONDUCE SOLO A UNA PROTECCION PARCIAL. AISLAR LA SECCION DE LA PARED INTERIOR DE LA TOBERA REFRIGERADA POR AGUA CONTIGUA A LA PARED FRONTAL DE LA SECCION EXTERIOR, ES MUY COSTOSO EN CONSTRUCCION Y EN AISLAMIENTO. POR TANTO, SE PROPONE DISPONER ENTRE EL CANAL ANULAR (17) PARA EL GAS PLASMA Y UN CANAL ANULAR (33) ENTRE LA PIEZA DE LA TOBERA (3) Y LA ENVOLVENTE DEL SOPLETE (16), CANALES DE TRANSFERENCIA (43, 44) UNIFORMEMENTE DISTRIBUIDOS EN LA PERIFERIA, A TRAVES DE LOS CUALES SE DERIVA UNA PARTE DEL GAS PLASMA QUE SE EMPLEA PARA LA REFRIGERACION DE LA ZONA EXTREMA DE LA TOBERA Y PARA DESVIAR PRECIPITACIONES DE POLVO O SIMILARES CONDUCTORAS ELECTRICAMENTE Y LOS ARCOS DE PLASMA EN RETROCESO. UNA BRIDA (29) CONDUCIDA DESLIZANTE EN ESTE CANAL ANULAR (33), CONTRARRESTA LA FORMACION DE PUENTES ELECTRICOS A CAUSA DE SUCIEDADES MEDIANTE MOVIMIENTOS RELATIVOS CAUSADOS POR LA TEMPERATURA.
