Embodiment
Below, according to embodiment the present invention is carried out more specific description.But scope of the present invention is not limited to this embodiment.
(test 1)
As embodiment 1～14 and comparative example 1～9, form shape as shown in table 1, the molten metal stirring body of material, and use each stirring body to measure degassing performance.
＜degassing performance 〉
It is in 730 ℃ the molten aluminum of 600kg that stirring body is immersed in melt temperature, the rotating speed that makes stirring body is 600rpm, feed argon gas as being blown into gas with 30L/min, under this state, make stirring body work and the processing that outgases, and make the molten metal after the degassing is handled flow into mold, the cross section state of the foundry goods that visual observation obtains.If the state that does not have a pore for " ◎ ", establish the state that almost do not have pore (not in-problem degree aspect practical) for " zero ", establish the state that there is pore (in-problem degree aspect practical) for " △ " and estimate.
[table 1]
Than 1: the projection floorage of path slot part part and the ratio of agitating vane projection floorage partly
Than 2: the length of path slot part part and the ratio of the radius of agitating vane
Than 3: the ratio of outer circumferential side open end groove width and interior all side openings end groove width
Than 4: the ratio of the degree of depth of path slot part and the groove width of outer circumferential side open end
(result)
Embodiment 1～14 is the state that does not have the state of pore or almost do not have pore, is good result.Comparative example 1～9 has all produced pore, is bad result.
From this result as can be seen, shown in embodiment 1～14, if the ratio of the projection floorage of path slot part part and the projection floorage of agitating vane part is 0.25～0.55 scope, then is the evaluation of " zero " or " ◎ ", is the stirring body with good degassing performance.
And, shown in comparative example 1～9, below 0.17 or under the situation more than 0.61, then be the evaluation of " △ " at the ratio of the shadow area of path slot part part and the projection floorage of agitating vane part, can confirm not outgas fully.
Owing to these reasons, think under the projection floorage of path slot part part with respect to the projection floorage of agitating vane part is the situation of 0.20～0.60 scope, to form stirring body with good degassing performance.
(test 2)
As the stirring body of embodiment 15～23 and comparative example 10～13, form the stirring body of shape shown in Figure 16.Such formation as shown in table 2 such as the interior perimembranous of agitating vane and the wall thickness of peripheral part, diameter, the following formation of shape of taper portion, notch part, path slot part.
Taper portion
Length: with respect to diameter is 12%
Highly: 8mm
Notch part
Width: with respect to diameter is 10%
The degree of depth: with respect to diameter is 10%
Two jiaos of R:4mm
The path slot part
Width: with respect to diameter is 5%
The degree of depth: the wall thickness with respect to peripheral part is 50%
The projection floorage of path slot part part is with respect to the ratio of the projection floorage of agitating vane part: 0.34
Use the stirring body of embodiment 15～23 and comparative example 10～13 to carry out following resistance to sudden heating test.Its result shown in the following table 2.
[table 2]
Than perimembranous wall thickness/periphery wall wall thickness in the 5=
Than perimembranous wall thickness/diameter * 100 in the 6=
Material
A silicon nitride series pottery
B silicon carbide system pottery
The grand system of C match pottery
The D carbon ceramics
(resistance to sudden heating test)
Not carrying out preheating just is immersed in embodiment 15～23 and comparative example 10～13 from normal temperature (about 20 ℃) and is adjusted into the molten aluminum of certain temperature and kept 5 minutes.Then stirring body is extracted out from molten aluminum and cooled off in atmosphere, Visual Confirmation has flawless, and utilizes following metewand to judge.
◎: postcooling does not have crackle yet in 800 ℃ the molten aluminum even if be immersed in.
Zero: be immersed in that postcooling does not have crackle in 750 ℃ the molten aluminum, if but be immersed in postcooling in 800 ℃ the molten aluminum then have crackle.
△: be immersed in that postcooling does not have crackle in 700 ℃ the molten aluminum, if but be immersed in postcooling in 750 ℃ the molten aluminum then have crackle.
*: be immersed in that also there is crackle in postcooling in 700 ℃ the molten aluminum.
(result)
Embodiment 15～23 is not cracking more than 750 ℃ in the resistance to sudden heating test.Comparative example 10～13 all cracks at 750 ℃ in the resistance to sudden heating test, and comparative example 13 also cracks at 700 ℃.
Like this, according to the result of comparative example 10,11,, therefore think that about 0.9～2.0 is suitable when of ratio (interior perimembranous wall thickness/peripheral part wall thickness) resistance to sudden heating decline when being 0.7 and 2.2 of interior perimembranous wall thickness with the peripheral part wall thickness.
And according to the result of comparative example 12,13, resistance to sudden heating descends when interior perimembranous wall thickness and diameter ratio are 3.0% and 10%, and the perimembranous wall thickness is about 4.0%～9.0% to be suitable with respect to the ratio of diameter in therefore thinking.
