ABSTRACT:
Highly effective insulated samplers, submerged through floating slag on a body of molten metal, successfully extract, chill and withdraw pin samples and disc samples of specific, predetermined shapes and sizes with high reliability. Deoxidant materials are introduced into the melt just before the sample is taken, whenever required. To eliminate gas bubble inclusions from the chilled samples, ablative deoxidant chambers are employed to carry the deoxidant materials, and are then melted away by the high temperature molten metal being sampled. A disc sampler chill mold provides three rows of vent slots to produce rapid and reliable chilling of disc-shaped samples.
