A liquid-cooled melting furnace panel for a melting furnace that contains molten glass during use, the melting furnace panel comprising a metal wall and a cast sacrificial layer in direct contact with a surface of the metal wall that faces the molten glass during use, wherein, prior to installation of the furnace panel in the melting furnace, an entire thickness of the cast sacrificial layer has a composition that includes glass cullet particles held together by a sodium silicate binder, said composition being meltable in molten glass.
A liquid-cooled melting furnace panel for a melting furnace, comprising:
- a first wall;
- a metal wall spaced apart from the first wall;
- an interior space defined between the first wall and the metal wall with fluid passages in the interior space through which a coolant entering the interior space flows along a first face of the metal wall;
- and
- a cast sacrificial layer carried by and in direct contact with a second face of the metal wall opposite the first face of the metal wall and within a perimeter of the metal wall,
- wherein, prior to installation of the furnace panel in the melting furnace, an entire thickness of the cast sacrificial layer has a composition consisting essentially of a material that is meltable in molten glass.
