Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1 and Figure 2, the utility model mainly comprises burner hearth 1 and furnace bottom 2, burner hearth 1 is provided with slag notch 3 and tapping hole 4, the plane of tapping hole is a little less than slag notch plane, between the magnesia brick layer 21 of furnace bottom 2 and argillic horizon 23, be provided with magnesia layer 22, the mode that magnesia brick layer 21 and argillic horizon 23 are intersected according to odd even layer center line by layer brick body is built by laying bricks or stones.
Producing due to titanium slag is generally to complete smelting process under the high temperature of 1600～1800 DEG C, the heat of the furnace bottom 2 of titanium slag stove is except from the heat by conduction of molten bath, the heat that also has furnace bottom power consumption to produce, so its temperature is higher, it is the most violent region of magnesian thermal expansion, between magnesia brick layer 21 and argillic horizon 23, be provided with the magnesia layer 22 that adopts dry method to build by laying bricks or stones, because the porosity of magnesia layer is high compared with magnesia brick, its retractility is larger, so can well compensate the thermal expansion of magnesia brick layer 21, thereby prevent from bursting because of expansion the situation of furnace bottom.On the other hand, furnace bottom is also subject to the souring of metal bath except being subject to high temperature and corroding, in order to strengthen stability and the corrosion resistance of furnace bottom, furnace bottom magnesia brick layer and argillic horizon all adopt layer brick body to build by laying bricks or stones according to the cross one another mode of center line of building by laying bricks or stones of odd even layer, best embodiment is as shown in Figure 4 and Figure 5, odd even layer center line differs 45 degree, and this structure can effectively prevent that metallic solution from corroding bottom of furnace body along building gap by laying bricks or stones.
Because furnace bottom is the most violent place that is heated, so for better heat radiation, on furnace bottom argillic horizon, be provided with multiple air vents 24, argillic horizon 23 retractilities on the one hand with air vent are better, can absorb the expansion of a part from magnesia brick layer, accelerate on the other hand the heat radiation of furnace bottom by the interaction energy of blower fan, thereby alleviate the thermal expansion of furnace bottom.
Burner hearth part integrated cost and durability are considered, adopt magnesia brick to build by laying bricks or stones in the burner hearth below average charge level, average charge level adopts high-alumina brick to build by laying bricks or stones above, because it is less that part more than average charge level touches the frequency of metal bath, be difficult for being etched, and high-alumina brick refractoriness is a little less than the normal smelting temperature of titanium slag, but serviceability temperature is the same with magnesia brick, so can meet melting demand, key is that its cost ratio magnesia brick is cheap, can be cost-saving.On the other hand, the magnesia brick contacting metal melt of burner hearth internal layer, and temperature is higher, and the outer field magnesia brick of burner hearth is heated relatively low, according to experience in the past, because the MgO composition in magnesia brick can affect the quality of product titanium slag, the thermal coefficient of expansion of magnesia brick is also relevant with its purity simultaneously, so when internal layer adopts the magnesia brick that purity is 95%, skin can reach a best economic and practical effect while adopting 91% magnesia brick.
Adopt 96%～98% high-purity magnesium brick masonry at slag notch 3 and tapping hole 4 places, because of the experience from the past, the place the most easily going wrong on burner hearth 1 is the region near slag notch 3 and tapping hole 4, therefore the purity that increases these two local magnesians can well improve its erosion resistant ability, in order to make its structure tightr, all adopt craspedodrome brick to build by laying bricks or stones with the mode that double buckle modular tile combines in these two places, through hole is left in centre, double buckle modular tile is positioned at the sandwich layer position of outlet second half section, and all the other regions are craspedodrome brick.Adopt this structure further to extend its service life.
As the improvement to such scheme, for burner hearth 1 and furnace bottom 2 can be limited in the time there is slight external drum, prevent that furnace shell steel plate from being burst by liner, can be at the arranged outside flint clay layer 5 of burner hearth 1 and furnace bottom 2.In the time laying flint clay, only need be flattened gently, reserved certain hole between flint clay layer 5 and argillic horizon 23, the one, play the buffering to bloating, the 2nd, can get rid of efficiently the gas in stove.
Further, for the heat exchange of better isolated burner hearth 1 and furnace bottom 2 and external environment, can on burner hearth flint clay layer outer wall, alumina silicate fibre layer 6 be set, asbestos board 7 is set on the outer wall of furnace bottom flint clay layer, because of the compressible space of aluminium silicate fiber peacekeeping asbestos board very large, and heat insulating ability is fine, so can not only well play adiabatic effect, also can effectively offset the expansion of furnace lining.
