The utility model solves the technical scheme that its technical problem adopts: the anti-expansion structure of titanium slag stove, comprise body of heater and be arranged at the magnesia furnace bottom in body of heater, between the furnace bottom of body of heater and magnesia furnace bottom, be provided with the magnesia knotting bed of material, in the stove inwall of body of heater, be provided with the magnesia knotting bed of material of stove inwall.
Further, on the furnace outer wall of body of heater, be provided with refractory aggregate layer.
Further, on described refractory aggregate layer outer wall, be provided with alumina silicate fibre layer.
Further, described alumina silicate fibre layer is socketed with asbestos board outward.
Further, in body of heater, be provided with stove eye.
The beneficial effects of the utility model are: in the time of actual production, the expansive force maximum of bearing with the stove inwall of body of heater between furnace bottom and magnesia furnace bottom is also the most direct, the utility model is by being provided with the magnesia knotting bed of material between the furnace bottom at body of heater and magnesia furnace bottom, on the stove inwall of body of heater, be provided with the magnesia knotting bed of material of stove inwall, because the porosity of magnesia stamp mass is high compared with magnesia brick, therefore the compressibility of magnesia stamp mass is larger, therefore can effectively offset the suffered power of furnace bottom magnesia brick expanded by heating.The utility model design is simplified and is practical, and effect is very remarkable, can effectively absorb the thermal expansion of magnesian, thereby fundamentally solves furnace shell " bulge " and be out of shape or burst the technological deficiency of furnace shell.The utility model can be in the designing and making of the relatively large titanium slag stove furnace lining of metallurgy industry.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
In figure, be labeled as: body of heater 1, stove inwall 11, furnace outer wall 12, stove eye 13, furnace bottom 14, magnesia furnace bottom 2, the magnesia knotting bed of material 3, the magnesia knotting bed of material 4 of stove inwall, the magnesia daubing bed of material 41, refractory aggregate layer 5, alumina silicate fibre layer 6, asbestos board 7.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
The anti-expansion structure of titanium slag stove as shown in Figure 1, comprises body of heater 1 and is arranged at the magnesia furnace bottom 2 in body of heater 1, is provided with the magnesia knotting bed of material 3 between the furnace bottom 14 of body of heater 1 and magnesia furnace bottom 2, is provided with the magnesia knotting bed of material 4 of stove inwall in the stove inwall 11 of body of heater 1.
Between stove inwall 11, furnace bottom 14 and magnesia furnace bottom 2, be the most violent region of thermal expansion of bearing magnesian, hot environment is not only born in above-mentioned two regions for a long time, also needs to bear the expansive force of magnesian, and historical facts or anecdotes is the most easily to occur damaged region in trampling.Because the porosity of magnesia stamp mass own is high compared with magnesia brick, therefore the compressibility of magnesia stamp mass is larger, therefore set up the magnesia knotting bed of material 4 of the magnesia knotting bed of material 3 and stove inwall and can effectively offset the suffered power of furnace bottom magnesia brick expanded by heating, thereby solve thoroughly loss of sheet body 1 " bulge " and be out of shape or burst the defect of the furnace shell of body of heater 1.
As the improvement to a upper scheme, in order to prevent that furnace outer wall 12 from can be limited in the time there is slight external drum, thereby prevent the excessive external drum of furnace outer wall 12 and occur breaking, refractory aggregate layer 5 can be set on the furnace outer wall of body of heater 1 12.Described refractory aggregate layer 5 is generally made by high temperature resistant and comparatively hard material.General, the Thickness Design of refractory aggregate layer 5 is 15～50mm, in the time putting into refractory aggregate layer 5, gently described refractory aggregate layer 5 is flattened, need to be at refractory aggregate layer and the reserved certain hole of furnace outer wall 12, the one, play the buffering to magnesia bloating, two can get rid of the gas in stove efficiently.
