High temperature insulating container

An insulating container for placement over a hot metal ingot or like article to lower heat loss, equilibrate article temperature and prevent scaling, and comprising:

• spaced apart inner and outer side walls, said container having top walls that are spaced apart,
• the spacing between said top walls and said side walls having insulation therein,
• said insulation comprising layers of thin, reflective radiation foil shields spaced apart by fibrous ceramic layers,
• the outer side wall being higher than the inner side wall, the spacing between said top walls being substantially greater than the spacing between said side walls, the outermost top wall being spaced above said insulation in the spacing between said top walls to define an expansion space,
• getter means located in said expansion space for absorbing oxygen, the interior of said container for said article defined by said inner side wall and the innermost top wall,
• the bottom of said inner side wall being opened for placement of said container over said article,
• seal means located at the bottom of the container and surrounding the opening, said seal means extending between the bottom edges of said inner and outer side walls and thereby limiting air into said container to prevent oxidizing of said shields,
• check valve means in said container providing communication between said expansion spaced and the exterior thereof to regulate pressure.
