The invention discloses a furnace hearth of a maintaining room of an aluminum alloy melting furnace built by combining casting materials with precast bricks. The furnace hearth overcomes the problem of shrunken pass-through sews in the furnace hearth of the existing maintaining room. The furnace hearth is characterized in that a firebrick layer is an aluminum liquid contact layer which is paved bycombining the high alumina casting materials with the precast bricks, and the middle positions of the precast bricks are previously provided with ring-shaped grooves on the height direction. The furnace hearth has the benefits that the building process of the furnace hearth of the maintaining room of the aluminum alloy melting furnace is simple and fast due to the structure built by combining thehigh alumina casting materials with the precast bricks, and quincuncial piles-shaped technology seams are formed on the surface of an aluminum liquid contact layer due to the convex-concave-shaped technology seams are formed
