Abstract:
1. An elastically interconnected cooler compressed hearth and walls, comprising: one or more tiers of wall-cooling blocks with internal coolant passages, and shaped into arc segments and each wall-cooling block having flanges by which they are joined together side-by-side and tops-to-bottoms to form complete sets of tiered rings to form a cylindrical wall for a round-bottom pyrometallurgical furnace; and a plurality of spring-bolt assemblies installed through and between adjacent ones of said flanges and across expandable joints between individual wall-cooling blocks, and configured to allow the spaces between the joints to expand with pressure as metal infiltrates refractory and/or hearth brick held inside said tiered rings; wherein, a tensioned binding ring or shell is not needed to prevent slag leakage and not included; and wherein, the refractory and/or hearth brick held within said tiered rings is compressed from outside by only the combination of the tiers of wall-cooling blocks and their interconnecting spring-bolt assemblies toward the center to disallow slag leakage through.
