Abstract
A furnace sidewall having slag retainers and metallurgical furnace having the same metallurgical furnace are disclosed herein. In one example, a furnace sidewall is provided that includes a hot plate and a plurality of slag retainers. The hot plate has an inner surface facing configured to face an interior volume of a metallurgical furnace and a bottom surface configured to face a hearth of the metallurgical furnace. The plurality of slag retainers extend inwardly from the inner surface of the hot plate and are arranged in a macro-pattern of slag retainer groups. The slag retainer groups include at least two or more of the slag retainers arranged in a micro-pattern.
Claims20
A furnace sidewall comprising:
- a hot plate having an inner surface facing configured to face an interior volume of a metallurgical furnace and a bottom surface configured to face a hearth of the metallurgical furnace;
- and
- a plurality of slag retainers extending inwardly from the inner surface of the hot plate, the plurality of slag retainers arranged in a macro-pattern of slag retainer groups, the slag retainer groups comprising at least two or more of the slag retainers arranged in a micro-pattern.
A furnace sidewall comprising:
- a ring-shaped steel hot plate having an inner surface facing inward;
- and
- a plurality of slag retainers welded to the inner surface of the hot plate, the slag retainers projecting inward from the inner surface, the plurality of slag retainers are arranged in a pattern of discrete slag retainer groups, the retainer groups having a substantially similar micro-pattern comprised of at least two spaced apart slag retainers of the plurality of slag retainers, the two spaced apart slag retainers having different geometric orientations.
A metallurgical furnace, comprising:
- a hearth;
- and
- a sidewall disposed on the hearth and surrounding an interior volume of the metallurgical furnace, the sidewall comprising:
- a hot plate having an inner surface facing the interior volume;
- a cover plate surrounding the hot plate in a spaced-apart relation;
- a plurality of spray nozzles disposed in a volume defined between the cover plate and hot plate, the spray nozzles oriented to spray a liquid on the hot plate;
- and
- a plurality of slag retainers welded to the inner surface of the hot plate, the slag retainers projecting inward from the inner surface, the plurality of slag retainers are arranged in a pattern of discrete slag retainer groups, at least two of the retainer groups having a substantially similar micro-pattern comprised of at least two spaced apart slag retainers of the plurality of slag retainers, the two spaced apart slag retainers having different geometric orientations.
