Fig. 2 and Fig. 3 is to have the cutaway drawing of the slide gate nozzle of valve plate shown in Fig. 1 figure, and Fig. 2 illustrates the state opened,
Fig. 3 illustrates the state of closedown.
Refer to Fig. 1 to Fig. 3, the valve plate 110,120 of the present embodiment is laminated to each other and constitutes slide gate nozzle 200.That is, slip water
Mouth 200 is made up of upper valve plate 110 and lower valve plate 120, and two valve plates 110,120 have the structure identical with the valve plate 100 shown in Fig. 1
Become.
Being as the criterion with lower valve plate 120, it is contrary that upper valve plate 110 is configured to left and right.That is, when the 4th minor face 24 He of lower valve plate 120
When 5th minor face 25 is towards right side, the 4th minor face 24 of upper valve plate 110 and the 5th minor face 25 are towards left side.
The aperture 19 of upper valve plate 110 connects the state to keep molten steel to flow all the time with filling pipe end (not shown).Instantly valve
When the aperture 19 of plate 120 is overlapping with the aperture 19 of upper valve plate 110, slide gate nozzle 200 is in open mode, when lower valve plate 120 is sliding
When moving and block the aperture 19 of valve plate 110, slide gate nozzle 200 is switched to closed mode.
Referring again to Fig. 1, the valve plate 100 of the present embodiment is formed as heptagon, therefore relative to having the existing of other shapes
Valve plate can make stress generation be down to minimum.Such as, the valve plate without the first long limit 11 and the second long limit 12 becomes pentagon, and
The valve plate 100 of the present embodiment can reduce maximum stress value relative to pentagonal valve plate.
By ratio based on δ 1 and δ 2 under conditions of identical clamp pressure effect and the first minor face 21 and the second minor face 22
The Numerical results of maximum stress size of tilt angle theta change be shown in table 1 below.Maximum stress represents and acts on valve plate
The maximum tensile stress of 100, the crackle of the least generation of its size is the fewest.
[table 1]
In table 1, sample 1 is pentagonal valve plate, and sample 2 to sample 9 is heptagonal valve plate.Understand, to sample 1 to
Under conditions of sample 9 applies identical clamp pressure, compared with sample 1, the maximum stress of sample 2 to sample 9 reduces.Especially, phase
For the length of whole valve plate 100, the length on the first long limit 11 and the second long limit 12 is the biggest, and maximum stress more can greatly reduce.
These results indicate that relative to the length of valve plate, the length on the first long limit and the second long limit is the longest, identical in applying
Clamp pressure under conditions of, the horizontal direction composition of clamp pressure becomes big, therefore, it is possible to suppress more because thermal expansion produces
Stress.
And, in the valve plate 100 of the present embodiment, the first long limit 11 is divided into the Part I 11a and second of two parts
The length ratio δ 1: δ 2 of part 11b and using the 4th minor face 24 as the base of the right angled triangle of hypotenuse and height ratio k1:k2
Relevant with the stress of valve plate 100.
Fig. 4 is the numerical analysis knot illustrating the maximum stress size based on δ 1/ δ 2 change for sample 10 to sample 13
The curve chart of fruit.The style characteristic of sample 10 to sample 13 is shown in table 2 below.
[table 2]
As shown in Figure 4, it can be seen that for sample 10 to sample 13, along with δ 1/ δ 2 value becomes big, valve plate 100 produces
Maximum stress diminishes.For valve plate 100, the effect that maximum stress reduces can be obtained when δ 1/ δ 2 value is more than 2.Especially, exist
In sample 11 to sample 13, when δ 1/ δ 2 value is more than 2, maximum stress change is little.
In valve plate 100, the lower limit of δ 1/ δ 2 value is 2, can increase δ 1/ δ 2 and be worth in the range of can realizing, but δ 1/ δ 2
Being worth the biggest, the material used is the most, therefore could be arranged to δ 1/ δ 2 and meets the scope of 2 to 3.5.
Fig. 5 is the numerical analysis knot illustrating the maximum stress size based on k1/k2 change for sample 14 to sample 17
The curve chart of fruit.The style characteristic of sample 14 to sample 17 is shown in table 3 below.
[table 3]
As shown in Figure 5, it can be seen that for sample 14 to sample 17, the maximum that the least valve plate of k1/k2 value 100 produces
Stress is the least.For valve plate 100, when k1/k2 value is less than 2.75, it is possible to obtain the effect that maximum stress reduces.It addition, not
The valve plate that k1/k2 value is less than 1.5 can be produced.Therefore, it can be set to k1/k2 and meet the scope of 1.5 to 2.75.
Additionally, length δ 1 and the 3rd of the total length of the valve plate 100 of the present embodiment and overall width and Part I 11a, 21a
The length of minor face 23 is relevant with the displacement i.e. haul distance of lower valve plate 120 during slide gate nozzle 200 action.Valve plate 100 in Fig. 1
Total length D1 represent, overall width D2 represents.Further, in Fig. 3, haul distance S of lower valve plate 120 represents.
The total length D1 of valve plate 100 could be arranged to 2 times that meet haul distance S to 3 times.Total length when valve plate 100
When D1 is less than 2 times of haul distance S, insufficient along the length of the valve plate 100 of valve plate 100 direction of action, therefore at the shape closed
Under state, lower valve plate 120 can not block the aperture 19 of valve plate 110, may result in molten steel leakage.It addition, the overall length of valve plate 100
When degree D1 exceedes 3 times of haul distance S, owing to using too much material to cause the producing cost of valve plate 100 to increase.
The overall width D2 of valve plate 100 could be arranged to 1 times that meets haul distance S to 1.5 times.The overall width of valve plate 100
When D2 is less than 1 times of haul distance S, the first long limit 11 and the second long limit 12 and aperture 19 can be too close to, therefore from aperture 19
Vertically may crack.During it addition, the overall width D2 of valve plate 100 exceedes 1.5 times of haul distance S, although valve plate
The performance of 100 will not change, but can waste used material.
Length δ 1 of Part I 11a, 12a could be arranged to 0.2 times that meets haul distance S to 0.5 times.And the 3rd
The length of minor face 23 could be arranged to 0.5 times that meets haul distance S to 1 times.
As it has been described above, the valve plate 100 of this embodiment is formed as heptagon, and it is applied in the of chucking power by optimization
One minor face the 21, second minor face the 22, the 4th minor face 24 and the angle of inclination of the 5th minor face 25 and length, it is possible to reduce on valve plate 100
The maximum stress produced.Its result, by cracking on suppression valve plate 100, can improve the service life of valve plate 100.
Above presently preferred embodiments of the present invention is illustrated, but the invention is not limited in this, can be in claim
Carrying out various deformation in the range of book, description and accompanying drawing, these fall within protection scope of the present invention.
