Abstract

UN METODO PARA LA PRODUCCION DE NODULOS DE HIERRO HA SIDO DESCUBIERTO, EN EL CUAL HA SIDO INTRODUCIDO UN NODULIZADOR DENTRO DEL PROCESO DE FUNDIDO DEL METAL PARA SER TRATADO EN DOS ETAPAS. EN PARTICULAR LAS INCORPORACIONES TIPICAS, SE TRATAN DE UN AGENTE NODULIZADOR QUE ES INTRODUCIDO EN EL PASO PREVIO A LA FUNDICION DEL METAL, DENTRO DE LA CAVIDAD DEL MOLDE Y, EN EL SEGUNDO PASO, EL AGENTE NODULIZADOR QUE ESTA DENTRO DE LA CAVIDAD DEL MOLDE O UNA CAMARA ADJUNTA, INMEDIATAMENTE DE SU PREVIA INTRODUCCION DEL METAL A SER MOLDEADO O LE ES AÑADIDO EL AGENTE A LA CORRIENTE LIQUIDA DEL METAL DURANTE SU PASO A LA CAVIDAD DEL MOLDE.A METHOD FOR THE PRODUCTION OF IRON NODULES HAS BEEN DISCOVERED, IN WHICH A NODULIZER HAS BEEN INTRODUCED WITHIN THE METAL MELTING PROCESS TO BE TREATED IN TWO STAGES. IN PARTICULAR THE TYPICAL INCORPORATIONS, THEY ARE A NODULIZING AGENT THAT IS INTRODUCED IN THE STEP BEFORE METAL CASTING, WITHIN THE MOLD CAVITY AND, IN THE SECOND STEP, THE NODULIZING AGENT THAT IS INSIDE THE MOLD CAVITY AN ATTACHED CAMERA, IMMEDIATELY FROM ITS PREVIOUS INTRODUCTION OF THE METAL TO BE MOLDED OR THE AGENT IS ADDED TO THE LIQUID CURRENT OF THE METAL DURING ITS PASSAGE TO THE MOLD CAVITY.
