Abstract
The utility model discloses a groove carbon block for a molten iron flow groove of an ore-smelting electric furnace. The groove carbon block comprises a carbon block, wherein a trapezoid groove, of which the bottom is cambered, is formed on the upper surface of the carbon block. The groove carbon block has a simple construction process and low baking difficulty; and the service life of a groove wall is long.
Description
Technical field
The utility model belongs to fire resisting material field, is specifically related to a kind of groove charcoal piece.
Background technology
At present, the chute liner between ladle and the pig machine, reproducibility ore-smelting electric furnace tapping hole outer chute liner are built the bottom by laying bricks or stones with high-alumina brick, brick fuel mostly, and top smashes material with carbonaceous or sa is smash material, the ramming concavity cell wall that taps a blast furnace.This canal wall construction difficulty is big, and the engineering time is long, and after baking in 6-12 hour, just can come into operation.During baking, can't guarantee the whole thermally equivalent of this cell wall, often crack, cause the cell wall local damage, and baking temperature be generally 300-600 ℃, can not reach the minimum sintering temperature of cell wall, causes cell wall intensity low, not anti-washing away, service life is short.
The utility model content
The utility model technical problem to be solved provides a kind of ore-smelting electric furnace stream molten iron tank with groove charcoal piece.
Adopt following technical scheme in order to solve the problems of the technologies described above: a kind of ore-smelting electric furnace stream molten iron tank comprises the charcoal piece, the trapezoidal groove that it is arcuation that the upper surface of charcoal piece is provided with a bottom with groove charcoal piece.
Described bottom is the trapezoidal groove of arcuation, and the bottom is the arc groove of chord length 100mm ~ 120mm, is starting point with two end points of circular arc, excavates a following hem width 100-120mm, and the isosceles trapezoid groove of last hem width 150-250mm constitutes trapezoidal groove.
The end face of charcoal piece and the angle between the bottom surface are 90 °.
The end face of the charcoal piece that is connected with tapping hole and the angle between the bottom surface are 95-105 °.
Employing the utility model work progress is simple, little, the cell wall long service life of baking difficulty.

Fig. 2 is the structural representation of the utility model embodiment 1.
The specific embodiment
Embodiment 1: a kind of ore-smelting electric furnace stream molten iron tank comprises charcoal piece 1, the trapezoidal groove 2 that it is arcuation that the upper surface of charcoal piece is provided with a bottom with groove charcoal piece.The bottom of trapezoidal groove is the arc groove of chord length 100mm ~ 120mm, is starting point with two end points of circular arc, excavates a following hem width 100-120mm, the isosceles trapezoid groove of last hem width 150-250mm.The end face of charcoal piece and the angle between the bottom surface are 90 °.
Embodiment 2: a kind of ore-smelting electric furnace stream molten iron tank is with groove charcoal piece, and the end face 3 and the angle between the bottom surface 4 of the charcoal piece that is connected with tapping hole are 95-105 °.Other are with embodiment 1.
During use; The ore-smelting electric furnace stream molten iron tank of embodiment 1 is connected with groove charcoal piece successively; Constitute the stream molten iron tank; The stream molten iron tank closely contacts with tapping hole brick face shown in embodiment 2 with groove charcoal piece with the ore-smelting electric furnace stream molten iron tank of electric furnace tapping hole joint, and the cancellation ramming mass connects, and can effectively prevent the damage of furnace lining that this position metals run out and causes.
Claims (4)
