CONTAINERS FOR MOLTEN METAL

摘要

Containers for molten metal having a permanent refractory lining and a molten metal contacting inner lining have in at least one place, separating the permanent and inner linings a layer substantially consisting of heat-carbonisable sheet material. The sheet material carbonises during use to yield a carbonaceous parting layer which facilitates removal of skull and the inner lining without damage to the permanent lining.
