The middle body of the sleeve 7 that contacts with molten metal in this roller docks with core 6, and is mechanically being retrained by the clamping part 3 of side plate 4 and ring-type, and core 6 is fixed in the rotating shaft 2 by its hub portion 1.The cooling fluid that circulating shown in the arrow of Fig. 6 in the inside of sleeve 7 and core 6 makes sleeve 7 coolings.
In above-mentioned roller,, bigger thermal deformation is arranged leaving on the position of constriction, and the degree of this thermal deformation increased along with the casting time because sleeve 7 mechanically retrained by core 6.
This is because the thermal stress that sleeve 7 produces surpasses yield stress, causes the stress decrease that is connected of sleeve 7 and core 6.In addition, extend the sleeve 7 and the slip between the core 6 that cause both chimeric surfaces are ground off, cause connection power slowly to descend, produce the gap finally owing to the heat of sleeve 7.
Therefore, along with the casting time determines that the thermal change deformation of the chill roll of casting plate shape is greatly a shortcoming.
With regard to the work of cooling cylinder, when making as the material that pyroconductivity is low with steel, sleeve 7 can only use a few minutes, just also can only reach the limitation when making with several hours as the material that pyroconductivity is high with copper alloy.And near this limit, the thermal deformation meeting surpasses 1000 μ m, and the deviation of the protuberance of casting sheet also can surpass ± 50 μ m, and this also is a shortcoming.
A problem of the present invention is that the cooling cylinder that can eliminate the aforementioned shortcoming of being seen and can fully prevent thermal deformation in the cooling cylinder of continuous casting apparatus will be provided, and can cast out central authorities' high-quality banded cooling cylinder of casting sheet little with two ends thickness of slab difference continuously thereby provide.
Another problem of the present invention is to make the heat conduction that is transmitted on the cooling cylinder from molten metal little, and the heat that is transmitted on the cooling cylinder is removed rapidly, and, the corrosion resistance of cooling cylinder and rigidity are improved prevent distortion, make its life-span long.
The present invention also have a problem be to provide rigidity high and can make that the heat of coming from molten metal conduction removes have a refrigerant cooling cylinder of currency structure sleekly.
It is will provide can make from the next heat of molten metal conduction to remove the heterogeneity that can prevent Temperature Distribution simultaneously again, the cooling cylinder with such refrigerant circulation structure rapidly that the present invention also has a problem in addition.
