... for optimum soundness of ingots cast in this study. Microprobe analysis showed that titanium segregation was associated with centerline defects in ingot cast from thermally reduced pebble. It was suggested that the addition of 0.25 to 0.5 wt% Al be made to the melt to eliminate centerline defects. However...

..., the power is decreased to allow the pool (up to 65% of the ingot length) to solidify without the development of harmful defects. A few hours may be required for hot topping larger ingots, and sufficient electrode metal must be available. It is especially important that the top of the ingot not be allowed...

... 1,800 to 18,000 kg (4,000 to 40,000 lb). Ingots may require conditioning after melting, depending on the cast surface quality to remove surface pinholes and spongy areas, which could contribute to tearing during the ingot breakdown stage. These melt-related surface imperfections are removed by spot...
