ABSTRACT:
A metallurgical furnace, which includes a furnace shell, an exhaust system, and a gas cleaning system, further includes a plurality of improved pipes and fume ducts throughout to increase operational life and productivity. The pipes and fumes ducts are comprised of an aluminum-bronze alloy which provides enhanced properties over prior art materials including thermal conductivity, modulous of elasticity and hardness. The use of the alloy also minimizes maintenance requirements of the pipes and fume ducts, thereby extending their operational life. In operation, gases formed from smelting or refining are evacuated from the furnace shell through the exhaust system into the gas cleaning system. The gases, as well as the system, are water cooled by way of the plurality of pipes displaced throughout.
