Described groove or projection are swallow-tail form, circle or polygon.

The angle of described groove or the swallow-tail form of projection is Ф=45 ° ~ 65 °.

The height I removing part of described groove or the circle of projection is 1/2nd of circular radius.

Refractory brick is rectangle or outside is large, inner side is little wedge shape.

Cooling water pipe is also had in the outside of furnace wall.

Stove outer covering is also had in the outside of cooling water pipe.

The utility model compared with prior art tool has the following advantages:

1, groove or projection are set on refractory brick and furnace wall, utilize together with refractory brick is firmly embedded in furnace wall by the groove on refractory brick and furnace wall or projection, avoid refractory brick expanded by heating and cause thermal shock and the phenomenon come off, substantially prolongs the kiln furnace life in industrial production, reduce the material consumption in production and cost of labor, improve production efficiency, play the important function of energy-saving and emission-reduction simultaneously.

2, at the arranged outside cooling water pipe of furnace wall, effectively reduce the temperature of furnace wall and refractory brick, make the mosaic texture between refractory brick and furnace wall more firmly with stable, and improve furnace lining opposing high-temperature gas erosion performance, extend the service life of furnace lining, and then extend the furnace life of Industrial Stoves.
