Abstract

See full text

An elastically interconnected cooler compressed hearth comprises a concave dished bottom lined with a sub-layer and a working layer of hearth bricks. Cylindrical walls that rise up from the rim of the concave dished bottom are constructed with one or more tiers of coolers shaped into arc segment blocks that are joined together by their flanges to form complete rings. The outer perimeter of the hearth brick within the ringed tiers is inwardly compressed toward the center to disallow any leaks from forming between the separate bricks. The coolers are elastically interconnected at their flanges by fasteners and springs. Each spring can be individually adjusted to obtain optimal working pressures on the whole of the core wall and hearth floor bricks.
