Carbon composite furnace lining structure for ferronickel electric furnace

The invention provides a carbon composite furnace lining structure for a ferronickel electric furnace in order to solve the problem of short life of the ferronickel electric furnace. The carbon composite furnace lining structure comprises a furnace bottom and a furnace wall, high-aluminum ramming materials are arranged at the position, closely attached to a furnace shell, of the furnace wall, special-grade high-aluminum bricks are built in the mode of being closely attached to the high-aluminum ramming materials, high-thermal-conductivity and erosion-resistant semi-graphitization carbon bricksare built outside a certain distance of the thermal faces of the special-grade high-aluminum bricks, and carbon ramming materials are rammed between wide seams of the special-grade high-aluminum bricks and the semi-graphitization carbon bricks; and carbon ramming materials are arranged at the furnace bottom, and protecting bricks are built at the positions which are closely attached to the thermal faces of the semi-graph
