Abstract
The invention provides an anode furnace oxido-reduction mouth brick hot-state replacement method. The method comprises the steps of manufacturing a rectangular steel plate mold, manufacturing conical refractory bricks and the like. A novel anode furnace comprises a furnace shell, a reaction furnace, square refractory bricks, a furnace shell arc-shaped movable steel plate, an oxido-reduction tube, the conical refractory bricks and the steel plate mold. The anode furnace oxido-reduction mouth brick hot-state replacement method aims at solving the problem that production is influenced by replacement of the refractory bricks at an oxido-reduction mouth of the anode furnace in the industry, shortening the time of influence of replacement of the bricks at the oxido-reduction mouth on production as much as possible, guaranteeing that the effective production time is long and effectively controlling the production operation cost; hot-state replacement of the bricks at the oxido-reduction mouth of the anode furnace is achieved, the replacement time is shortened, and the labor intensity of workers replacing the bricks at the oxido-reduction mouth is relieved.
Description
Technical field
The invention belongs to nonferrous metallurgical equipment technical field, be specifically related to a kind of Novel anode stove.
Background technology
Anode furnace redox mouth refractory brick region is the maximum region of anode furnace body of heater fluctuation of operating conditions, this region is in blowing pressurized air for a long time and enters in stove, or be in and spray solid reductant or reducibility gas and do restore job, this region refractory brick is in for a long time cold and heat succeed each other, magnesia fire-protecting wall is very easily degraded or is consumed.The service life of other region magnesia fire-protecting walls of usual anode furnace is even longer more than 2 years, but redox mouth magnesia fire-protecting wall service life is generally at about 3 months, namely degraded to 300mm thickness less than, be in dangerous thickness.For this reason, Copper making factory, usually to the replacing of this region magnesia fire-protecting wall, just needs blowing out process.
General anode furnace blowing out cooling down is at least after 5d, and operating personnel just can enter in stove, removes the magnesia fire-protecting wall that redox port area need be changed, re-uses new magnesia fireproof brick masonry.After this region magnesia fire-protecting wall changes, baker heats up again, could heat up and reach normal production operation condition after at least needing 2d.For this reason, change redox mouth magnesia fire-protecting wall and cause larger impact to enterprise's production, not only affect output, affect normal production operation, also need to drop into energy consumption baker and heat up.
Summary of the invention
For solving above technology Problems existing, the invention provides and a kind of save replacing construction, reducing the method that workman changes redox mouth brick labour intensity, and a kind of can the Novel anode stove of hot replacing redox mouth brick.
Its technical scheme is:
The hot replacing options of a kind of anode furnace redox mouth brick, is characterized in that: carry out according to following steps,
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 on the inner box hat in anode furnace redox mouth position;
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, use clamp card good;
F, install redox pipe, redox pipe enters in reacting furnace through furnace shell arcuate movement steel plate and taper refractory brick, and anode furnace can heat up the operation that returns to normal production gradually;
G, through work after a while, taper refractory brick is degraded to during lower than 300mm thickness, opens furnace shell arcuate movement steel plate, takes out by the taper refractory brick degraded, taper refractory brick new in replacement, and shuts furnace shell arcuate movement steel plate.
A kind of Novel anode stove, comprise furnace shell, reacting furnace, square firebrick and redox pipe, the flame retardant coating that square firebrick is piled into is provided with in furnace shell, described anode furnace also comprises taper refractory brick, steel plate mould and furnace shell arcuate movement steel plate, steel plate mould is welded on the inner box hat in anode furnace redox mouth position, steel plate mould inside is provided with taper refractory brick, furnace shell one end is provided with furnace shell arcuate movement steel plate, furnace shell arcuate movement steel plate one end and furnace shell hinged, the furnace shell arcuate movement steel plate other end is connected with furnace shell is separable, filling is piled up by square firebrick in space between taper refractory brick and steel plate mould, redox pipe enters in reacting furnace through furnace shell arcuate movement steel plate and taper refractory brick.
After anode furnace redox mouth refractory brick uses certain hour, when this region refractory brick thickness is less than 300mm, the refractory brick that need change can be removed in the hot situation of anode furnace, in steel plate mould, build the fixed ready-made taper redox mouth magnesia fire-protecting wall of in advance design by laying bricks or stones, to the area filling fire clay outside taper brick and build fritter square brick by laying bricks or stones.After the work of building by laying bricks or stones in steel plate mould completes, can install furnace shell arcuate movement steel plate, after using clamp card good, installation redox pipe, namely hot more the changing jobs of anode furnace redox mouth brick accused, and anode furnace can heat up the operation that returns to normal production gradually.Need not in the hot situation of blowing out at anode furnace, the replacing of antianode stove redox mouth brick is realized outside stove, replacement operation is simple, convenient, fast can not be caused producing larger impact, and the blowing out avoiding former replacing options is lowered the temperature and a large amount of energy consumption wastes that baker heats up.
Further, square firebrick and taper refractory brick are magnesia fire-protecting wall, and refractoriness is high, have good repellence to basic slag and copper ashes.
Further, on furnace shell arcuate movement steel plate near being provided with handle with the separable one end place be connected of furnace shell.Such design, is easy to open furnace shell arcuate movement steel plate, changes magnesia taper refractory brick.
Accompanying drawing explanation
Fig. 1 is can the structural representation of anode furnace of hot replacing redox mouth brick;
Wherein, 1-furnace shell, 2-reacting furnace, 3-steel plate mould, 4-taper refractory brick, 5-square firebrick, 6-redox pipe, 7-furnace shell arcuate movement steel plate, 8-handle.
