縮に対応させている。[Prior Art] A continuous steel casting machine uses a mold that continuously cools and solidifies injected molten steel to cast a steel billet. As this type of mold, a configuration in which a taper is formed on the inner surface of a mold wall forming one side of the mold is known. This taper is formed so that the space into which molten steel is injected narrows downward. By providing a taper that narrows at the bottom in this way, it is possible to cope with the shrinkage of the slab that occurs when molten steel solidifies.

面には、通常°、鋳片による鋳型の摩耗を抑制するため
に一様にＮ１めつき層が形成されている。In a continuous casting machine using such a mold, molten steel injected into the mold is cooled and solidified within the mold to form a slab, which is continuously drawn out from the mold. In this case, the inner surface of the mold is worn away by the slab when the slab is pulled out. Normally, an N1 plating layer is uniformly formed on the inner surface of the mold in order to suppress wear of the mold by slabs.

くしている。そのため、鋳型壁の内面に形成されるテー
バは上方と下方では傾きが異なるように形成されたいわ
ゆる多段テーパを有する鋳型が用いられている。By the way, when a slab condenses in the mold, the molten steel that has flown in above the mold is rapidly cooled and most of it solidifies, and below the mold, a part of the molten steel in the center solidifies, so the volume of condensation increases. are different. That is, in the upper part of the mold, there is a large amount of condensation, so the slope of the taber (slanted surface) is made large, and in the lower part, the amount of condensation is small, so the slope of the taber is made small. Therefore, a mold having a so-called multi-stage taper, in which the taper formed on the inner surface of the mold wall has different slopes at the upper and lower sides, is used.

ジ）で修復のため交換または使用不能になる。[Problems to be solved by the invention] However, in the part of the inner wall of the mold where the taper changes, the abrasion resistance against the slab is greater than in other parts, so the plating layer wears out severely, and the wear only occurs in this part. becomes unusable. For example, the mold can be replaced for repair or become unusable after about 1/4 to about 1/7 the number of charges (about 50 charges) compared to a mold without a taper.
このように、従来のテーパが多段に形成された鋳型では
、鋳型の、寿命が短いという問題点がある。As described above, the conventional mold in which tapers are formed in multiple stages has a problem in that the life of the mold is short.

It is characterized in that an inclined surface is formed with a varying inclination angle, and a wear-resistant alloy is welded onto the surface of the portion where the inclination angle changes.

）を形成する。As shown in FIGS. 1 and 2, in the inner wall 18 of the mold with the short side 32.34, the surface of the copper plate material 24 extends from the upper end to the midway part 39 (hereinafter referred to as the "chever change part") with a hollow 37. The first taper 41A is formed such that the first taper 41A becomes narrower. From the Taber change portion 39 to the lower end,
A second taper 41 having a smaller inclination angle than the first taper
8 is formed. In this way, by forming a multi-stage taper whose inclination angle changes along the direction in which the slab is pulled out, it is possible to respond to the volume change caused by condensation when molten steel solidifies. Furthermore, as shown in FIG.
．． 34 mold inner walls 18 are formed with adjacent edges 40 forming corners. ``This edge 40 cooperates with the long walls 28,30 to form a corner area 42 (see FIG. 3).

よる効果が小さい。The edge 40 is coated with a wear-resistant alloy, such as a nickel-chromium alloy, a nickel-cobalt alloy, etc., with a thickness of about 0.5 mm in the region of width A from the taper change portion 39 to the lower end of the mold.
It is thermally sprayed at a volume of 0.6 ml to 0.6 ml. In this case, the width A of the edge 40 on which the wear-resistant alloy is sprayed is equal to the width A of the short side wall 32.
Assuming that the width of is 8, the spray is applied to the area shown by the following equation (1). -A>B/2X0.3...
...(1) Here, the coefficient 0.3 in equation (1) indicates the ratio to the width of the edge, and if it is 0.3 or more, the width A becomes relatively wide. , the spraying area of the wear-resistant alloy becomes wider, which increases the cost. On the other hand, if it is less than 0.3, the thermal spraying area of the wear-resistant alloy will be relatively narrow and the effect of thermal spraying will be small.
尚、縁部領域４０を除く領域にはニッケルめっき層が形
成されている。Note that a nickel plating layer is formed in the area except for the edge area 40.
次に、この発明の実施例の動作について説明する。Next, the operation of the embodiment of this invention will be explained.
第１図に示すように、タンデイツシュ１２の溶鋼を浸漬
ノズル１６を介して鋳型１４に供給する。As shown in FIG. 1, molten steel from a tundish 12 is supplied to a mold 14 through a submerged nozzle 16.

て冷却され、完全に凝固する。The molten steel supplied to the mold 14 is cooled by the mold inner wall 18 to form a solidified shell. The slab portion in which unsolidified molten steel exists inside the solidified shell is cooled by spraying cooling water in a spray cooling zone provided below the mold, and is completely solidified.

から、この部分の急激な摩耗は抑制される。Mold 14 has an MRI inside! A cooling section 20 is provided to remove the heat conducted from 118. In the cooling section 20, cooling water is supplied to the passage 22 from the bottom to the top, as shown by arrow E in FIG. Therefore, the heat of the molten steel in the mold is transferred to the cooling water via the mold inner wall 18. When the slab is cooled, it is cooled sequentially starting from the part that contacts the mold inner wall 18, and the upper part of the mold is rapidly cooled and condensed when molten steel flows into the mold. However, since the mold is tapered to follow the change in volume of the slab, even if the volume of the slab changes, the slab is pulled out along the shape of the mold. In this case, the frictional resistance at the three taper changing portions increases, but since wear-resistant metal is sprayed on the edge portions, rapid wear at these portions is suppressed.

角頭域４２の凝固シェルＳが堅いから、この領域では、
凝固シェルＳと鋳型内壁との摩擦が大きく作用するので
鋳型内壁の摩擦抵抗が大きい。In addition, since the cooling efficiency of the portion of the square head 1142 sandwiched between the long side wall (28 or 30) and the short side wall (32 or 34) is relatively high, the solidified shell of the portion close to this square head region 42 S is stiffer than the central portion 38. in this way,
Since the solidified shell S in the square head region 42 is hard, in this region,
Since the friction between the solidified shell S and the inner wall of the mold is large, the frictional resistance of the inner wall of the mold is large.
更に、鋳型内壁１８に形成されているテーパは、短辺壁

抑制することができる。Further, regarding the taper formed in the mold inner wall 18, the taper 36B of the short side wall 32.34 is larger than the taper 36B of the long side wall.
The inclination angle with respect to the moving direction of the slab is larger than that in A. Therefore, the edge 4 of the mold inner wall 18 at the short side wall 32.34
Il of 0! Although the frictional resistance is extremely high, since a wear-resistant metal is sprayed on this edge 40, wear of this portion can be suppressed.

．． The wear condition of the inner wall of the mold 34 is the wear of the edge 40 sprayed with wear-resistant metal, and the wear of the chrome-plated central part 36.
Although the wear is approximately equal, the remaining portion can be made approximately uniform over the entire area of the plating plate. Therefore, local abrasion of the edges of the inner wall of the mold is prevented and the remaining portion is made approximately uniform, so that the copper material 24 will not be eroded.
この発明は上述した一実施例に限ることなくこの発明の
要旨を逸脱しない範囲で種々変形可能である。This invention is not limited to the one embodiment described above, and can be modified in various ways without departing from the gist of the invention.
例え″ば、テーパ変化部分から鋳型の下端にまで耐摩耗
性金属の溶射を施したがこれに限らずテーバ変化部分だ
けに溶射を施してもよい。For example, although the wear-resistant metal is thermally sprayed from the taper changing portion to the lower end of the mold, the present invention is not limited thereto, and the thermal spraying may be applied only to the taper changing portion.
また、上述した実茄例では短辺壁に付いてのみ説明した
が、長辺壁についても同様にテーパの変化部分に耐摩耗
性金属を溶射しても同様な効果を得ることができる。Further, in the above-mentioned example, only the short side walls have been described, but the same effect can be obtained by spraying a wear-resistant metal on the taper change portions of the long side walls as well.

Therefore, a mold with a long life can be provided.
