Construction execution of DKJL ceramic fiber products used in calcium carbide furnaces.

A calcium carbide furnace is a high-temperature industrial furnace used to produce calcium carbide (CaC₂) through the reaction of lime (calcium oxide, CaO) and coke (carbon, C) at temperatures exceeding 2,000–2,200°C. The process occurs in an electric arc furnace, where an electric arc generates the extreme heat required for the endothermic reaction:
CaO+3C→CaC₂+CO
The furnace is critical in industries such as acetylene gas production, steelmaking, and chemical synthesis.

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.
