Specific implementation mode
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
The metallurgical furnace of the embodiment of the present invention is described referring to Fig. 1.
Metallurgical furnace according to the ... of the embodiment of the present invention, metallurgical furnace include furnace shell and the refractory protection that is located in furnace shell, metallurgical
Stove has furnace bottom, the refractory protection 100 on furnace bottom including insulating layer 10, be located at insulating layer 10 above and by laying fireproof bricks and
At permanent layer 20, be located at permanent layer 20 above and the working lining 30 made of laying fireproof bricks and be located above working lining 30
And the first impermeable layer 40 formed by ramming mass.
The furnace bottom of metallurgical furnace according to the ... of the embodiment of the present invention stacks gradually shape by protective layer, permanent layer 20, working lining 30
At an entirety, permanent layer 20 and working lining 30 are piled up using refractory brick into so that protective layer has preferable fire resistance,
And the first impermeable layer 40 being made of ramming mass is set above working lining 30 between the refractory brick to forming working lining 30
Brickwork joint covered, make metallurgical furnace have preferable anti-permeability.
In a preferred embodiment, refractory protection 100 further includes being located between insulating layer 10 and permanent layer 20 and by smashing
The second impermeable layer 50 that dnockout is formed.In this way, the second impermeable layer 50 be arranged between insulating layer 10 and permanent layer 20 with into
One step enhances the anti-permeability of refractory protection 100.It will appreciated by the skilled person that the first impermeable layer 40 and
The constituent of two impermeable layers, 50 respective specific thickness and ramming mass can be arranged as required to.
Advantageously, the side docking of the adjacent refractory brick 31 of working lining 30 or partial transposition, side are inclined-plane.Specifically,
In specific example shown in Fig. 2, adjacent two refractory brick docking of composition working lining 30, i.e., the side of two refractory brick 31
It is completely superposed.In specific example shown in Fig. 3, two adjacent 31 partial transpositions of refractory brick of composition working lining 30, i.e., two
The side of a refractory brick 31 only partially overlaps.
Further, the refractory brick 31 of working lining 30 is truncated rectangular pyramids shape or wedge shape.Specifically, shown in Fig. 4 specifically to show
In example, the refractory brick 31 of working lining 30 is truncated rectangular pyramids shape, and the extended line of four inclines of the truncated rectangular pyramids is met at a bit.In Fig. 5 institutes
In the specific example shown, the refractory brick of working lining 31 is wedge shape, and the extended line of the incline of the wedge shape intersects on straight line.By
This, locks mutually in working lining 30 between adjacent refractory brick, makes to be completely embedded inside refractory protection 100, reliably.
Referring to Fig.1, it is additionally provided between working lining 30 and the first impermeable layer 40 between the refractory brick of covering working lining 30
The barrier bed 60 of brickwork joint.Barrier bed 60 covers the brickwork joint of working lining 30 to prevent foreign matter from entering the brickwork joint of working lining 30 as a result,.
Wherein, working lining 30 and/or the refractory brick of permanent layer 20 be magnesia brick, magnesite-chrome brick, magnesia-alumina brick, magnesia carbon brick, alumina chrome brick,
One kind in carbon brick, silicon carbide brick.In this way, enhancing the high temperature resistance of refractory protection 100, erosion resistibility.
Preferably, insulating layer 10 is formed by clay brick or high alumina brick masonry.Insulating layer 10 has heat-insulated, sound insulation, inhales as a result,
The advantages that damp.
Selectively, furnace bottom is antiarch shape or segment-shaped.Specifically, when furnace body is block furnace, furnace bottom uses antiarch
Shape；When furnace body is round kiln, furnace bottom uses segment-shaped.In this way, the locking between being conducive to the refractory brick at metallurgical furnace bottom, keeps away
The dislocation movement of refractory brick is exempted from.
The furnace bottom of the metallurgical furnace of the embodiment of the present invention uses refractory protection 100, insulating layer 10 to form the outside of furnace bottom, the
One impermeable layer 40 forms the inside of furnace bottom.In metallurgical furnace blow-on temperature-rise period, the first impermeable layer 40 can prevent metallurgy
Molten metal in stove enters working lining 30；After the bottom temperature of metallurgical furnace increases and maintains a period of time, working lining 30 it is resistance to
Firebrick fully expands and the brickwork joint between adjacent refractory brick fully makes up, even if the first impermeable layer 40 is worn, working lining 30
Brickwork joint it is closed, remain to prevent metallurgical furnace in molten metal penetrate into working lining 30.
