ある。As shown in Fig. 2, the method of this erosion test is to use a container 3 made of firebrick blocks I and 2, which are test objects formed to a predetermined size, and to put the solution into the container 3. , by vibrating this container 3 vertically or horizontally using a vibration device (not shown), the friction of the solution against the inner surface of the container 3 is strengthened, thereby eroding the bricks to some extent, and then measuring the degree of erosion. There is.

あった。[Problems to be Solved by the Invention] In the above method, the erosion of the bricks occurs because the inner wall surface of the container 3, that is, the inner wall surface 1a of the block 1, is subjected to severe stirring resistance due to the flow of the solution. However, in the method described above, the erosion force was weak, and it took a long time to notice a significant difference in the erosion dust of the refractory. The time can be shortened by violently vibrating the container 3, but this method is difficult because the solution tends to scatter. In addition, a large amount of bricks is required, and therefore a large vibration device is required to fit the container 3.
Furthermore, there were other problems such as the solution leaking between the blocks.

する。At the tip of the brick support rod 12 of the vibrating device IO, a brick test piece 1 made of a refractory brick, in this case, a maguro brick, a magnesia brick, a dolomite brick, etc., is formed into a rectangular parallelepiped shape.
4 is fixed. In this fixing method, a hole is made in the center of one end surface of the test piece 14, and the tip of the support rod 12 is inserted into the hole and fixed.

wt%, and the melt temperature was 1250" C). During the test, the crucible 15 is always heated by a heating device (not shown) so that the melt does not cool and solidify and the melt temperature is maintained.

がある。Then, the test piece 14 is placed in the solution bath, and the drive source IO is activated to vibrate the test piece 14 up and down. At this time, the vibration stroke is adjusted so that the support rod 12 is not immersed in the melt and all surfaces except the upper surface of the test piece 14, that is, the surface in which the support rod 12 is fitted, are in contact with the melt. As a result, the test piece 14 is eroded by the solution. At this time, the vibration is mainly applied only to the test piece 14, and therefore the erosion to the crucible 15 is so small that it is not a problem compared to the test piece 14 (1 degree). "The change in the shape of the test piece 14 after the test piece 14 is vibrated by the vibration device IO for a predetermined time and number of times to evaluate the degree of erosion, that is, the change in the shape of the test piece 14 from the surface of the test piece 14 before the test. The amount of erosion may be measured, the degree of penetration may be measured from changes in weight, or the cross section of the test piece 14 may be observed to measure the depth of penetration of the solution.

関関係を測定することもできる。According to the method described above, since the size of the test piece 14 can be small, there is an advantage that the vibrating device 10 used can also be made smaller. Also, since the solution is not stirred, crucible 15
Since the test piece 14 can be subjected to high vibrations, the erosion progresses rapidly, and the test time becomes tighter and shorter. Furthermore, it is possible to observe the erosion state of the corner portion of the test piece 14, and also to compare the difference in erosion depending on the type of brick shape, not limited to the rectangular parallelepiped as in this example. Furthermore, by adjusting the vibration speed, it is also possible to measure the correlation between the degree of erosion and the vibration speed on the test piece 14 of the solution.
