Step furnace lining structure is stung to ferronickel electric stove brickwork overlap joint

The utility model aims at providing a step furnace lining structure is stung to ferronickel electric stove brickwork overlap joint that reinforcing monolithic lining structural strength, reduction brickwork destroyed, the brickwork pastes tile, carbon composite brick, magnesium composite brick for high thermal -conductivity graphite from the stove outer covering to interior in proper order, high thermal -conductivity graphite pastes the tile and hugs closely the stove outer covering setting, and the adjacent high thermal -conductivity graphite of carbon composite brick pastes the tile and builds by laying bricks or stones, and the hot side at the furnace wall is built by laying bricks or stones to the magnesium composite brick, and the step is stung to carbon composite brick and magnesiumcomposite brick overlap joint, the thickness of carbon composite brick is the at least twice of magnesium composite brick thickness, every layer of at least two -layer magnesium composite brick of carbon composite brick overl
