  • Method for containing the molten reaction products of a reactive cladding process
    Patent number: 3933191
    Abstract: Method and apparatus for containing the molten reaction products of a reactive cladding process, such as an aluminothermic reduction cladding process, in which a refractory-lined perimeter rests on either a sand bed or a steel base. A second perimeter surrounding the inner perimeter and forming an annular space therewith is also situated on either the sand bed or the steel base. Sand placed in the annular space between the two perimeters chills any molten reaction products which escape the confines of the inner perimeter, preventing any spread of this material.
