Casting pit refractories for iron & steel industries

The importance of casting pit refractories and their properties have been discussed. A short review of literature has been made. Two types of casting pit refractories are generally used—one with comparatively high refractoriness and the other with low refractoriness and bloating or pyroplastic characteristics. The latter type, though preferred, is not made in the country. The possibility of manufacturing the pyroplastic type of casting, pit refractories from indigenous low alumina plastic clay with addition of pyrophyllite or talc has been indicated. © 1964 Taylor & Francis Group, LLC
