本願発明は得られる鋳片の品質を向上させると共に鉤型
自体の寿命を高める連続鋳造用鋳型に−するものである
。DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a continuous casting mold that improves the quality of the obtained slab and extends the life of the hook die itself.

自体が熱の為に強度が低下し使用に耐えられなくなる事
態が生じていた。In recent years, as continuous casting methods have become faster, the surface temperature of continuous casting molds has become higher, and the conventionally used surfaces with a layer of surface J, 2, KEL or nickel alloy do not only damage the surface. The strength of the copper or copper alloy mold body itself deteriorates due to heat, resulting in a situation where it becomes unusable.

。The present invention relates to a IIk type for continuous m# production which eliminates the above-mentioned drawbacks, and the gist thereof is to coat the inner surface of the mold body made of copper or copper alloy with an undercoat material made of Ni-Kel or Ni-Kel alloy. Molybdenum, molybdenum alloy, tungsten,
Tungsten alloy, tantalum, tantalum alloy, niobium,
This continuous casting mold is characterized in that it has an intermediate layer made of any one of niobium alloys, and a surface layer made of chromium or nickel-chromium alloy.

スカス部に於いては厚くする場合もある。In addition, since the area around the meniscus of a continuous casting mold is exposed to the Karasugata, heat fatigue resistance is mainly required, and the lower half is mainly required to have wear resistance against the solidified shell, so it must be highly heat resistant to meet these requirements. In some cases, the thickness of the Shenkai layer is increased at the upper meniscus.

くと一層効果的である。In addition, the material used as the opening layer of the mold of the present invention is generally brittle at low humidity and easily oxidized at high temperatures.In particular, the oxide of molybdenum easily volatilizes, so it is necessary to prevent peeling of the opening layer, prevent oxidation, and mold. In order to prevent heat shrinkage and deformation of the main body, it is more effective to wrap the surface layer around both end faces of the upper and lower parts so that the intermediate layer is not exposed.

ブデン合金（Ｍ・−Ｚｒ。The method of forming the opening layer in the present invention is not particularly limited, but is usually done by thermal spraying.The mold of the present invention will be described in detail below with reference to the drawings, as shown in Figure 11!1. The intermediate layer (3) is coated with an undercoat material (3) on the inner surface of the Kabura or Kabura alloy mold body (11) to improve its adhesion.

ある。The one shown in Fig. 2 has an intermediate layer (31) that becomes thinner as it goes from the upper part to the lower part, and a second surface layer (41) that becomes thicker. This is to counter the fact that the damage caused by heat is large, and the lower part of the mold is caused large damage by cracking scratches caused by the solidified shell and peeling that accompanies Gζ.

込んだ形態のものを示す。Moreover, what is shown in FIGS. 5 and 5 is a structure in which a surface layer (4) is wrapped around the upper and lower ends of the mold, and both ends of the mold, in order to compensate for the defects of the intermediate layer (3) mentioned above. FIG. 6 shows a structure in which an intermediate layer (3) and an undercoat material (2) are also rolled up in both halves to prevent thermal deformation.

着性を向上せしめて用いられる。The mold of the present invention is used after forming the undercoat material (2) -> the intermediate layer (3) -> the surface layer (4), and then subjecting it to a heat treatment to improve the adhesion between each layer.

事が出来るものである。As described above, according to the present invention, the high melting point metal or its alloy used as the intermediate layer has good thermal conductivity, so it has high deformation resistance in Affl. While maintaining high-temperature strength, the cooling through the copper or copper alloy mold is sufficient, so heat is accumulated in the mold, resulting in an increase in the temperature of the mold body and damage to the mold body. Together with the outermost nickel-chromium alloy layer, this creates a long-life continuous casting mold with no deformation and little wear, resulting in a product that is uniform and of high quality over a long period of time. It is possible to obtain.

ある。In addition, if the thickness of the opening layer is gradually reduced from the top of the mold to the bottom, and the surface layer is reversed, the above effect is further improved because it perfectly matches the damage to the mold during actual operation. ＃The life of the mold is greatly extended.%Furthermore, if a surface layer made of chromium or nickel-chromium alloy is wrapped around both the upper and lower end surfaces of the mold and both end surfaces of the mold, it protects the intermediate layer from oxidation and protects the intermediate layer from oxidation. It can also be expected to have the effect of preventing layer peeling and heat shrinkage deformation of the mold body.
