Abstract

When an automotive metalcasting facility was experiencing chill and hard spots on a component, it was decided that the in-filter inoculating system be investigated. Preliminary tests revealed that an inoculant filter could function as the primary inoculant and replace the need for stream inoculation entirely. As a result, further investigations were performed to discover the effectiveness of a combination of in-mold inoculation pellets with a filter for thin-wall gray iron casting applications. In the first phase of the investigation, the dissolution behavior of the inoculant pellet embedded into a ceramic foam filter was evaluated. In the second phase, an attempt was made to determine how effective the inoculant-filter assembly was in nucleating and cleansing the molten metal. Results show that the inoculation pellet properly dissolves and, along with the filter, helps remove non-metallic material from the metal.
