Substantially non-aqueous, plastic, high magnesium oxide refractory compositions are disclosed. The materials remain fluid over prolonged storage times, providing for easy workability and require no addition of water prior to use.

Basic (MgO) non-aqueous plastic refractory mixture

The base plates or stools of ingot molds used in the casting and teeming of molten steel can be repaired by spraying onto the ingot mold base plate from 2-5 gallons of a composition comprising:

Sprayable material for repairing base plates of ingot molds

An improved ingot mold base member comprising a cast iron base with a refractory insert disposed within its face. The refractory insert is positioned within a cavity in the cast iron base and attached with Z-shaped anchors, said anchors contacting a groove in the side of the insert and fastened to the bottom of the cavity. A channel between the edge of the refractory insert and the edge of the cavity is filled with a plastic refractory.

Ingot mold base member

A novel mold coating comprising humic acid, and/or humic acid salts, and graphite in a liquid suspension containing organic bonding agents is disclosed as well as a method of forming ingots in which molten steel is poured into molds which are covered by the coating.

Casting process with lignosulfonate-humate-graphite mold coatings

An improved ingot mold base member comprising a cast iron base with a refractory insert disposed within its face. The refractory insert is positioned within a cavity in the cast iron base and attached with Z-shaped anchors, said anchors contacting a groove in the side of the insert and fastened to the bottom of the cavity. A space between the edge of the refractory insert and the edge of the cavity is filled with a plastic refractory.
