Description
Technical field:
The utility model relates to the high temperature sintering furnace technical field, under 1200 ℃ of-1600 ℃ of high temperature, accomplishes the high temperature sintering furnace of sintering more specifically to a kind of luminescent material and other materials.
Background technology:
As shown in Figure 1; Existing luminescent material and other materials are accomplished sintering under 1200 ℃ of-1600 ℃ of high temperature high temperature sintering furnace has two kinds of tunnel electric furnace and cabinet-type electric furnaces, no matter be tunnel electric furnace and cabinet-type electric furnace, they all heat first A4 by furnace roof A1, furnace bottom A2, furnace side A3, Si-Mo rod and form; Furnace roof A1, furnace bottom A2, furnace side A3 form the heating furnace body of a sealing; Si-Mo rod heats first A4 and is fixed in the body of heater, during actual production, material to be sintered is placed crucible A5; Crucible A5 places on the push pedal A6, sends into then and carries out sintering in the body of heater.Its weak point is:
1, during sintering, after the Si-Mo rod energising, the interface temperature in hot junction can reach 1700 ℃-1800 ℃; The direct radiation of heat energy direction shown in arrow among Fig. 1 that Si-Mo rod heats first A4 is treated agglomerated material and is carried out sintering on pincers pot A5; Cause the Δ temperature difference in the thorax, when object is heated, exist the both sides heating temperature high, make crucible outside burn-off phenomenon have a strong impact on the product yield; The incomplete phenomenon of degree of crystallinity of the inboard material to be sintered of crucible is serious, has a strong impact on product quality; Make like this material to be sintered burn till quality and yield is relatively poor.
2, because the direct radiation of heat energy on crucible, makes pot life short.
The utility model content:
The purpose of the utility model is exactly the deficiency to prior art; And a kind of high temperature sintering furnace with directional heat radiation function is provided; It has improved product quality; Improved the finished product yield, for improving the product technology level and reducing cost, the competitiveness that improves product has certain realistic meaning.
The technological solution of the utility model is following:
High temperature sintering furnace with directional heat radiation function comprises that furnace roof, furnace bottom, furnace side, Si-Mo rod heating unit form, and furnace roof, furnace bottom, furnace side form the body of heater of a sealing; The Si-Mo rod heating element heater is fixed in the body of heater and places the front portion of two wing furnace sides respectively; Material to be sintered places crucible, and the pincers pot places in the push pedal, and the front portion of Si-Mo rod heating element heater is provided with baffle plate; Form heat energy radiation upper shed between baffle plate and the furnace roof, form heat energy radiation under shed between baffle plate and the furnace bottom.
Said baffle plate fixed strip two ends are separately fixed on furnace roof and the furnace bottom, and baffle plate is fixed on the baffle plate fixed strip.
The middle part of said furnace roof is circular arc.
The beneficial effect of the utility model is:
1, the material burn-off phenomenon to be sintered in the crucible outside obviously improves, and the utility model can improve product yield＞5%.
2, it is complete basically that the inboard material to be sintered of crucible burns till crystallization, and it can improve and burns till crystal property index about 3%.
3, crucible life prolongs >=10%.
4, its effect among the practical application of tunnel electric furnace is more obvious, simultaneously to a certain extent, and to the mild favourable prolongation Si-Mo rod life-span at high temperature of making full use of of imitating of Si-Mo rod heat and temperature fluctuation.
Description of drawings:
Fig. 1 is the prior art constructions sketch map
Fig. 2 is the structural representation of the utility model
Among Fig. 2: 1, furnace roof; 2, furnace bottom; 3, furnace side; 4, Si-Mo rod heating element heater; 5, crucible; 6, push pedal; 7, baffle plate; 7-1, heat energy radiation upper shed; 7-2 heat energy radiation under shed; 8, baffle plate fixed strip.
The specific embodiment:
Embodiment: see shown in Figure 2; High temperature sintering furnace with directional heat radiation function comprises that furnace roof 1, furnace bottom 2, furnace side 3, Si-Mo rod heating unit 4 form, and furnace roof 1, furnace bottom 2, furnace side 3 form the body of heater of a sealing; Si-Mo rod heating element heater 4 is fixed in the body of heater and places the front portion of two wing furnace sides 3 respectively; Material to be sintered places crucible 5, and crucible 5 places in the push pedal 6, and the front portion of Si-Mo rod heating element heater 4 is provided with baffle plate 7; Form heat energy radiation upper shed 7-1 between baffle plate 7 and the furnace roof 1, form heat energy radiation under shed 7-2 between baffle plate 7 and the furnace bottom.
Said baffle plate fixed strip 8 two ends are separately fixed on furnace roof 1 and the furnace bottom 2, and baffle plate 7 is fixed on the baffle plate fixed strip 8.
The middle part of said furnace roof 1 is circular arc.
Operation principle: because the heat energy homogeneous radiation on crucible 5, has prolonged the service life of crucible.
According to the temperature requirement of heated object, the mineralising reaction temperature curve of heated time and base-material etc. are the area and the position of the anterior plate washer 7 of design of Si molybdenum bar heating unit 4 usually, makes heat radiation flow to furnace roof and flows, and accomplishes hot-fluid by both sides to the top.Gathering formation hot-fluid turns to the hot-fluid of burner hearth center diffusion to reach the effect of temperature in the even thorax.Make the material burn-off phenomenon to be sintered in crucible 5 outsides obviously improve like this, the utility model can improve product yield＞5%.It is complete basically that the inboard materials to be sintered of crucible 5 burn till crystallization, and it can improve and burns till crystal property index about 3%.
