能である。2. Description of the Related Art The twin roll strip casting (twin drum) method is one of continuous casting methods and is a method for directly producing a metal ribbon from a molten metal. According to this method, since the final shape of the product can be obtained by light rolling, it is possible to simplify the process and equipment and reduce the cost.
【０００３】ツインロール式ストリップキャスト法は、
一対のロールの側部にサイドダムを配置して湯溜りを形
成し、両ロールを互いに反対方向に回転させ、その隙間
から金属薄帯を連続的に排出する構成になっている。The twin roll type strip casting method is
Side dams are arranged on the sides of the pair of rolls to form a pool of water, the rolls are rotated in opposite directions, and the metal ribbon is continuously discharged from the gap.
【０００４】ところで、サイドダムは、浸漬ノズル等の
鋳造用ノズルと類似の部材であり、このため、両者は同
じ材質で構成できると考えがちである。By the way, the side dam is a member similar to a casting nozzle such as an immersion nozzle, and therefore, it is apt to be considered that both can be made of the same material.
【０００５】確かに、サイドダムは鋳造用ノズルと同様

スラグに対する耐食性ばかりでなく、耐摩耗性及び摺動
性も要求される。Certainly, the side dam is a kind of refractory for casting like the nozzle for casting, and is a member that comes into contact with molten steel.
However, the side dam is also a member that slides in close contact with the roll. Therefore, the side dam is required to have not only corrosion resistance against molten steel and slag but also wear resistance and slidability.

性及び摺動性が要求されることは余り無い。この点で、
サイドダムは、鋳造用ノズルとは技術的に異なるもので
あり、両者を１つの範疇で論じることは適当でない。On the other hand, the casting nozzle is rarely required to have wear resistance and slidability. In this regard,
Side dams are technically different from casting nozzles and it is not appropriate to discuss them in one category.

０μｍ未満のＡｌ2 Ｏ3 及び最大粒径２５０μｍ未満の
Ｃを主構成物とすることを特徴としている。As mentioned above, the side dam 11 must have excellent sliding characteristics and abrasion resistance. From such a viewpoint, the side dam of the present invention has a maximum particle size of 5
It is characterized in that Al 2 O 3 having a particle size of less than 0 μm and C having a maximum particle size of less than 250 μm are main constituents.
【００２０】Ａｌ2 Ｏ3 の割合は３５〜６５重量％と
し、Ｃの割合は３５〜６５重量％とする。The proportion of Al 2 O 3 is 35 to 65% by weight, and the proportion of C is 35 to 65% by weight.

十分な強度及び耐食性を得ることができない。また、Ａ
ｌ2 Ｏ3 の割合が６５重量％を超えると、耐スポーリン
グ性が著しく低下する。When the proportion of Al 2 O 3 is less than 35% by weight,
Sufficient strength and corrosion resistance cannot be obtained. Also, A
If the proportion of l 2 O 3 exceeds 65% by weight, the spalling resistance is significantly reduced.
【００２２】Ｃの割合が３５重量％未満では、熱伝導性
が低下し、そのため耐スポーリング性が低下する。ま
た、Ｃの割合が６５重量％を超えると、耐食性が著しく
低下してしまう。When the proportion of C is less than 35% by weight, the thermal conductivity is lowered, and thus the spalling resistance is lowered. Further, if the proportion of C exceeds 65% by weight, the corrosion resistance is significantly reduced.
【００２３】Ａｌ2 Ｏ3 の最大粒径を５０μｍ未満及び
Ｃの最大粒径を２５０μｍ未満としたのは、十分な耐摩
耗性及び摺動性を得るためである。The maximum particle size of Al 2 O 3 is less than 50 μm and the maximum particle size of C is less than 250 μm in order to obtain sufficient wear resistance and slidability.
【００２４】このようなＡｌ2 Ｏ3 −Ｃ質材料に対し

It is desirable to add the following.

The reason why 0% by weight is used is that BN itself is expensive. B
The maximum particle size of N is preferably less than 50 μm. Maximum particle size is 5
If it is 0 μm or more, sufficient abrasion resistance and slidability may not be obtained.

動性を得ることができないことがある。It is possible to prevent carbon oxidation by adding B 4 C. However, if the addition amount of B 4 C increases, the thermal expansion coefficient and the dynamic elastic modulus increase and the spalling resistance decreases, so the addition amount is set to 5% by weight as the upper limit. The maximum particle size of B 4 C is preferably less than 50 μm. When the maximum particle size is 50 μm or more, sufficient wear resistance and slidability may not be obtained.

The amount of iO 2 added is 5% by weight or less. The maximum particle size of SiO 2 is preferably less than 50 μm. When the maximum particle size is 50 μm or more, sufficient wear resistance and slidability may not be obtained.

The maximum particle size of SiC is preferably less than 100 μm. If the maximum particle size is 100 μm or more, sufficient wear resistance and slidability may not be obtained. BN, B 4
In order to obtain the effect, C, SiO 2 , and SiC must be contained in a total amount of at least 1% by weight or more.

も、コストを無視すれば可能である。The maximum particle size of each raw material described above can be obtained by granulation. However, the particle size of the raw material substance has a great influence on the wear resistance. Therefore, as for the particle size of the additive, the particle size of the additive that has been scraped and dropped due to wear becomes a problem. Granulation with all raw material particle diameters of 1 μm or less is possible if cost is ignored.

B 4 C, SiO 2 , and SiC raw materials were used in the proportions shown in Table 1, and a side dam sample was manufactured by a usual method. The production procedure will be briefly described. After kneading the raw materials in the proportions shown in Table 1 and the organic binder, the mixture is molded by a rubber press and reduction firing is performed.

た。Using the manufactured side dam samples of Examples 1 and 2 and Comparative Examples 1 to 7, the bending strength was measured according to JIS R2.
It was measured by a three-point bending strength measurement method based on 619, and the coefficient of thermal expansion (at 1000 ° C.) and abrasion resistance were also examined.
【００３５】なお、耐摩耗性は、回転磨耗試験（ピン・

例４では両者の割合が明らかに本発明の範囲外であった
からと考えられる。As shown in Table 1, the bending strength of Comparative Example 1 was not so large, and the bending strength of Comparative Example 4 was clearly insufficient. The reason is that in Comparative Example 1, the proportions of Al 2 O 3 and C were outside the lower and upper limits of the present invention, and in Comparative Example 4, the proportions of both were clearly outside the scope of the present invention. Conceivable.
【００３８】また、比較例２では熱膨脹率が大き過ぎ、
比較例３では熱膨脹率がやや大きめであった。その理由

であり、一方、比較例３ではＣの含有量が本発明の下限
値外であったからと考えられる。In Comparative Example 2, the coefficient of thermal expansion is too large,
In Comparative Example 3, the coefficient of thermal expansion was rather large. The reason is considered that in Comparative Example 2, the C content was clearly outside the range of the present invention, while in Comparative Example 3, the C content was outside the lower limit of the present invention.

る。Further, in Comparative Examples 5 to 7, the abrasion resistance was insufficient and the sliding mirror surface of the side dam sample was rough.
This is because Al 2 O 3 having a particle size of 50 μm or more in Comparative Example 5.
It is considered that this is because the raw material, that is, the C raw material having a particle size of 250 μm or more was used in Comparative Example 6, and BN and B in Comparative Example 7.
It is considered that it does not contain 4 C, SiO 2 , or SiC at all.
