Further, the angle of the cross section of described inclined-plane and AOD stove brick is 5 °～20 °.

Further, described angle is 10 °.

Further, the spacing between described first plane and described second plane is 3～10mm.

Further, described spacing is 5mm.

Further, the length of AOD stove brick is 80～200mm, and wide is 50～150mm, and thick is 50～150mm.

Further, the length of described AOD stove brick is 80mm.

Further, one of them described end face of this AOD stove brick is globoidal structure or wavy shaped configuration.

Further, this AOD stove brick is magnesite-chrome brick, magnesite dolomite brick, dolomite brick or magnesia carbon brick.

Compared with prior art, the beneficial effects of the utility model are as follows:

1, adopt engaging structure, the arching that utilizes gradient to form between the stove brick connects, and cooperates firmly, and furnace lining is not yielding, and brick ring difficult drop-off has prolonged service life of AOD stove.

2, the spacing between the angle of the cross section of inclined-plane and AOD stove brick, first plane and described second plane all adopts than fractional value, both guaranteed the stability of engagement, also guaranteed the intensity of AOD stove brick, avoiding stove brick end face when being subjected to bigger power, ruptures because of insufficient strength in the engaging structure position.

3, the long L of AOD stove brick adopts less numerical value, has shortened the thickness of AOD inner lining of furnace, has increased the molten cavity area of AOD stove, can productivity gain.

4, an end face adopts globoidal structure or wavy shaped configuration, has both increased the lifting surface area of this end face and changed to be subjected to force direction, has prolonged the service life of stove brick and AOD stove.

5, adopt magnesite-chrome brick, magnesite dolomite brick, dolomite brick or magnesia carbon brick, fire resistance is stronger than the brick body of general material, and has good corrosion resistance.
