Abstract:
A method for accommodating increasing outward pressures in the tap holes of a hearth furnace includes configuring a tap hole lining and disposing it inside a hollow cylindrical conduit such that the tap hole lining can slide in response to outward pressures and growth in the hearth brick. The tap hole lining is retained inside the hollow cylindrical conduit with a retaining ring and spring assemblies.
