Construction execution of DKJL ceramic fiber products used in carbon baking furnaces.

A carbon baking furnace is a high-temperature industrial furnace used to calcine carbon-based materials (e.g., petroleum coke, coal tar pitch) into dense, electrically conductive carbon anodes or cathodes. These components are critical for aluminum smelting in the Hall-Héroult process. The furnace operates at temperatures up to 1,200–1,300°C, driving volatile matter out of the green carbon blocks and forming a hardened, thermally stable structure.

DKJL ceramic fiber products, as an important thermal insulation and refractory material for building this kind of furnace, can significantly reduce energy consumption and ensure its normal operation.
