A vertical, open-ended ingot mold assembly including a mold stool having a relieved portion machined in its base which machined relieved portion has a cavity therein produced by erosion during casting. The useful life of the mold stool is prolonged by providing a quantity of metal particles to fill the cavity and having a plate positioned over the cavity and metal particles, which plate is secured within the cavity by a ring that is within the relieved portion of the mold stool. This ring protects the periphery of the machined relieved portion from erosion during casting and also prevents the plate and metal particles from mingling with the cast metal. For each successive casting operation, the eroded cavity is filled with metal particles and a new plate is positioned thereover. Alternately, the use of metal particles may be avoided by using only a plate of a thickness sufficient to protect the remainder of the mold stool from erosion.
An ingot mold assembly for ingot casting including a vertical, open-ended mold removably positioned on a mold stool to enclose a surface area thereof, said mold stool having on said enclosed surface area a relieved portion, said relieved portion having a base with a cavity therein produced by erosion during casting, a quantity of metal particles essentially filling said cavity, a plate positioned within said relieved portion and covering said cavity and metal particles, and means within said relieved portion for securing said plate and for protecting the periphery of said relieved portion from erosion during casting, whereby during casting the plate and metal particles are secured in place and do not mingle with molten metal being cast and the periphery of the relieved portion is protected from erosion.
An ingot mold assembly for ingot casting including a vertical, open-ended mold removably positioned on a mold stool to enclose a surface area thereof, said mold stool having on said enclosed surface area a circular relieved portion, said circular relieved portion having a base with a cavity therein produced by erosion during casting, a quantity of metal particles essentially filling said cavity, a plate positioned within said circular relieved portion and covering said cavity and metal particles, and a ring positioned within said circular relieved portion and securing said plate, whereby during casting the plate and metal particles are secured in place and do not mingle with molten metal being cast and the periphery of the relieved portion is protected from erosion.
