Abstract
The invention relates to a method of fixing a shaped body of a refractory material to an interior face (e.g. of a wall) of an ingot mould in which an adhesive composition is applied to either the body or the face or both and the body and the face are urged together, the thus fixed body serving to identify an ingot when cast in the mould. In the method of the invention the adhesive composition is a mixture consisting essentially of aqueous alkali metal silicate such as sodium silicate and a particulate refractory material such as china clay, silica or zircon, the mixture having a viscosity of at least 2000 poises measured on a Brookfield Viscometer model RVT at 20.degree. C.
Claims11
A method of fixing a shaped body of a refractory material to an interior face of an ingot mould, which method comprises applying to at least one of said body and said face a mixture consisting essentially of aqueous alkali metal silicate and a particulate refractory material, the mixture having a viscosity of at least 2000 poises measured on a Brookfield Viscometer model RVT at 20.degree. C, and urging together said body and said face.
A method of casting molten metal to provide a marked ingot comprising the steps of
- fixing a shaped body of a refractory material to an interior face of an ingot mould by applying to at least one of said body and said face a mixture consisting essentially of aqueous alkali metal silicate and a particulate refractory material, the mixture having a viscosity of at least 2000 poises measured on a Brookfield Viscometer model RVT at 20.degree. C, and urging together said body and said face, and then
- pouring molten metal into said ingot mould.
An ingot having an identifying marking formed thereon by fixing a shaped body of a refractory material to an interior face of an ingot mould by applying to at least one of said body and said face a mixture consisting essentially of aqueous alkali metal silicate and a particulate refractory material, the mixture having a viscosity of at least 2000 poises measured on a Brookfield Viscometer model RVT at 20.degree. C, and urging together said body and said face, and then
- pouring molten metal into said ingot mound, and allowing the molten metal to harden.
