Furnace Copper Coolers
Tenova Pyromet’s high-intensity MAXICOOL® copper coolers, its innovative SAFECOOL® copper cooling system, and its novel composite copper-graphite coolers are proven to safely contain the molten furnace bath and prolong furnace campaign life. Our designs are tailored to the process requirements of each application, ensuring the maximum benefit to our clients.
Overview
By cooling the furnace sidewalls, the refractory life can be extended due to operating at a lower temperature, or, even better, a stable slag freeze lining can be formed on the sidewall hot face, acting like a natural, self-maintaining refractory crucible containing the slag bath.
Freeze lining formation occurs when the hot face of the furnace lining is cooled to a temperature below the freezing temperature of the liquid slag inside the furnace.
Once a freeze lining or accretion layer is established, the heat flux or loss through the furnace sidewall is a function of the process and not a function of the lining/cooling system design. The primary process parameters that determine the heat losses are the slag superheat, the slag viscosity, and the slag thermal conductivity.
