Abstract
A kind of method of the hot replacing of anode furnace oxidoreduction mouth brick, including make rectangular steel plates mould and make the steps such as taper refractory brick.A kind of Novel anode stove, including furnace shell, reacting furnace, square firebrick, furnace shell arcuate movement steel plate, oxidoreduction pipe, taper refractory brick and steel plate mould.The invention aims to solve the problems, such as that above-mentioned industry inner anode stove oxidoreduction mouth refractory brick is changed to Influence of production, reduced because changing time of the oxidoreduction mouth brick to Influence of production as far as possible, guarantee to produce effective time height, production operation cost is effectively controlled, and the method that a kind of hot replacing of anode furnace oxidoreduction mouth brick is provided, the hot replacing of anode furnace oxidoreduction mouth brick is realized, replacing construction is saved, the labor intensity that workman changes oxidoreduction mouth brick is reduced.
Description
Technical field
The invention belongs to nonferrous metallurgical equipment technical field, and in particular to a kind of Novel anode stove.
Background technology
Anode furnace oxidoreduction mouth refractory brick region is the maximum region of anode furnace body fluctuation of operating conditions, and the region is located for a long time
Enter in stove in blowing pressurized air, or reduction operation is done in injection solid reductant or reducibility gas so that the region is resistance to
Firebrick is chronically at and colds and heat succeed each other, and magnesia fire-protecting wall is easily degraded or consumed.Usual other region magnesia fire-protecting walls of anode furnace
Service life it is even longer more than 2 years, but oxidoreduction mouth magnesia fire-protecting wall service life is typically at 3 months or so,
Degraded to 300mm thickness less than in uneasy through thickness.For this purpose, Copper making factory is usually to the region magnesia fireproof
The replacing of brick, it is necessary to which blowing out is processed.
After general anode furnace blowing out cooling down at least 5d, operator could be entered in stove, remove oxidoreduction mouth region
The magnesia fire-protecting wall that domain need to be changed, reuses new magnesia fireproof brick masonry.The region magnesia fire-protecting wall is changed after finishing, again
Baker heats up, and could heat up and reach normal production operation condition after at least needing 2d.For this purpose, changing oxidoreduction mouth magnesia fireproof
Brick causes large effect to enterprise's production, not only affects yield, affects normal production operation, in addition it is also necessary to put into energy consumption baker liter
Temperature.
The content of the invention
To solve the problems, such as above technology, the present invention provides a kind of saving replacing construction, reduces workman and change oxidation
The also method of stomodaeum brick labor intensity, and it is a kind of can the hot Novel anode stove for changing oxidoreduction mouth brick.
Its technical scheme is：
A kind of hot replacing options of anode furnace oxidoreduction mouth brick, it is characterised in that：Follow the steps below,
A, making rectangular steel plates mould, steel plate mould is hollow structure；
B, making taper refractory brick；
C, the steel plate mould made is welded in inside anode furnace oxidoreduction mouth position on box hat；
D, by the taper laying fireproof bricks made in steel plate mould, to the area filling fire clay outside taper refractory brick
And build square firebrick by laying bricks or stones；
E, installation furnace shell arcuate movement steel plate are good using clamp card；
F, installation oxidoreduction pipe, oxidoreduction pipe pass through furnace shell arcuate movement steel plate and taper refractory brick to enter reacting furnace
Interior, anode furnace gradually can heat up the operation that returns to normal production；
G, through the work of a period of time, when taper refractory brick is degraded to less than 300mm thickness, open furnace shell arc and live
Dynamic steel plate, takes out the taper refractory brick for being degraded, taper refractory brick new in replacement, and shuts furnace shell arcuate movement steel plate.
A kind of Novel anode stove, including furnace shell, reacting furnace, square firebrick and oxidoreduction pipe, the side of being provided with furnace shell
The flame retardant coating that shape refractory brick is piled into, the anode furnace also include taper refractory brick, steel plate mould and furnace shell arcuate movement steel plate,
Steel plate mould is welded in inside anode furnace oxidoreduction mouth position on box hat, and steel plate mould is internally provided with taper refractory brick, stove
Shell one end is provided with furnace shell arcuate movement steel plate, and furnace shell arcuate movement steel plate one end is hinged with furnace shell, furnace shell arcuate movement steel plate
The other end is detachably connectable with furnace shell, and filling, oxygen are piled up by square firebrick in the space between taper refractory brick and steel plate mould
Changing reduction tube passes through furnace shell arcuate movement steel plate and taper refractory brick to enter in reacting furnace.
In anode furnace oxidoreduction mouth refractory brick using after certain hour, region refractory brick thickness less than 300mm when,
The refractory brick that need to be changed can be removed in the case of anode furnace is hot, in steel plate mould, the fixed ready-made cone of design in advance is built by laying bricks or stones
Shape oxidoreduction mouth magnesia fire-protecting wall, to the area filling fire clay outside taper brick and builds fritter square brick by laying bricks or stones.In steel plate mould
After the completion of building work by laying bricks or stones, you can install furnace shell arcuate movement steel plate, using clamp card it is good after, installation oxidoreduction pipe, anode furnace
Oxidoreduction mouth brick is hot more to change jobs to accuse and completes, and anode furnace gradually can heat up the operation that returns to normal production.In anode furnace not
Must blowing out it is hot in the case of, realize the replacing to anode furnace oxidoreduction mouth brick outside stove, replacement operation is simple, convenient, fast
Victory is not resulted in producing large effect, it is to avoid the blowing out cooling of former replacing options a large amount of energy consumptions waves that baker heats up again
Take.
Further, square firebrick and taper refractory brick are magnesia fire-protecting wall, and refractoriness is high, and basic slag and copper ashes are had very
Good repellence.
Further, the end detachably connectable with furnace shell is provided with handle on furnace shell arcuate movement steel plate.So
Design, is easy to open furnace shell arcuate movement steel plate, changes magnesia taper refractory brick.
