Title:
PLASTIC CHROMIUM ORE REFRACTORY COMPOSITION
Document Type and Number:
Japanese Patent JPS5443912
Kind Code:
A
Abstract:
In order to provide plastic chrome or refractory compositions which have a desirably low swelling or bloating tendency, without using asbestos or floc, compositions are introduced, which include hectorite, which is a naturally occurring or manufactured hydrous magnesium silicate material. The refractory compositions contain, by weight on a dry basis, 85 to 95% of size-graded chrome ore, 1 to 5% of alkali metal silicate binder, 0 to 5% of plasticizer (other than hectorite) and sufficient water to form a plastic mass, the amount of hectorite being 0.5 to 5%. The hectorite can constitute the sole plasticizer, but for cost reasons other plasticizers are also included, plastic clays being especially preferred.
