として形成する技術である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous casting mold and a method for manufacturing the same, and particularly relates to a mold for continuous casting and a method for manufacturing the same. We propose a unique technology for the mold and the plating method for its production. this is,
In view of the severe wear that occurs especially in the lower part of continuous casting molds, Ni-W is highly resistant to such wear.
- This is a technology that forms Fe ternary alloy plating as part of the plating layer on the inner wall of the mold.

の混入防止を図つている。 In general, continuous casting molds are made of copper or its alloy, which has good thermal conductivity, and the inner wall surface that comes into contact with the injected molten steel is mainly plated with nickel or chrome to provide heat and wear resistance. A metal plating layer is formed to protect the inner surface of the mold and to prevent the copper from entering the slab.

つていた。 Even with such a plated coated mold, the wear is severe, especially in the lower part, and the bare surface (copper) of the mold base is exposed after a relatively rapid number of uses, resulting in the above-mentioned disadvantages. Conventionally, attempts have been made to solve this problem by applying a high-hardness alloy plating to areas subject to severe wear, or by thermal spraying a wear-resistant metal onto the underlying nickel plating.

う問題点が知られていた。 However, these methods using high-hardness alloy coating layers are difficult because the mechanical properties (mainly elongation) of the alloy plating layer are significantly different from the copper forming the mold base and the underlying nickel. The drawback was that cracks frequently occurred due to fatigue. i.e. in a sulfamate bath
When Ni-W alloy plating is performed, as the W content increases, the columnar structure becomes more prominent and the hardness increases.
At 400H V or higher, cracks are likely to occur due to internal stress. On the other hand, when Ni-Fe plating is applied in a sulfamate bath, a layered structure is formed, but when the Fe content is increased and the hardness is increased to over 500H V , the layered structure collapses and becomes extremely brittle, causing the substrate to locally become thinner. and a covering layer,
Another known problem is that defects occur at the interface between each coating layer.

The purpose is to make suggestions regarding. The gist of the present invention to achieve this object is as stated in the claims at the beginning of this specification. The details of the configuration will be explained below.

なお、図示の４はクロムめつき層である。 In the mold of the present invention, as shown in FIG. 1, an electrolytic nickel plating layer 2 having a thickness of about 1 mm and having excellent adhesion is first formed on the inner wall surface of a mold base 1 made of copper or the like. On top of that, about 0.3 to 3 mm thick Ni (60 to 98 weight %) (1 to 20 weight %, preferably 5 to 7 weight %) and W (1 to 20 weight %, preferably 1 to 5 weight %) A ternary alloy plating layer 3 consisting of Fe is formed. This ternary alloy plating layer 3 may be formed only in the lower part of the mold where the wear is severe, and the hardness gradually increases in the range of 300 to 700 H V from the base 1 toward the inner wall surface in contact with the molten steel. It is important that the layer has a gradient.
Note that 4 in the figure is a chrome-plated layer.

ものと考えられる。 Figure 2 shows Ni-W (5-7%)-Fe (1-5%)
The ternary alloy according to the present invention and the conventional Ni-(7
%) with Fe binary alloy, it can be seen that the hardness of the Ni--W--Fe ternary alloy plating according to the present invention is superior to that of the binary alloy. This difference in hardness between the two is due to the fact that in the case of a ternary alloy, Fe acts as a promoter of the precipitation effect of W, and therefore W and Fe perform a precipitation hardening function in Ni plating, and Ni plating is face-centered. In contrast to the cubic lattice structure, Ni--W--Fe ternary alloy plating is thought to occur because the structure is dense with a close-packed hexagonal lattice.

If Fe ternary alloy plating is simply deposited on the base Ni plating layer, as mentioned above, the elongation of the Ni plating layer and the ternary alloy plating layer is significantly different, resulting in cracks and defects. There is a high possibility that this will occur.

たのである。 Therefore, in the present invention, in order to solve the above-mentioned problem, a hardness gradient is provided continuously in the thickness direction of the ternary alloy plating layer, and the hardness of the alloy plating layer on the base side of the mold is reduced. While aiming to improve adhesion by increasing the hardness of the inner wall surface, the aim was to improve wear resistance by increasing the hardness of the inner wall surface.

ることがよく判る。 As shown in Fig. 2, the method of creating a hardness gradient in the ternary alloy plating layer 3 is to gradually increase the amount of dissolved Fe in the plating bath (nickel sulfamic acid solution), and eventually increase the hardness at the cathode (mold). Fe of
This is carried out by gradually increasing the amount of reduced and precipitated ions. FIG. 3 shows the relationship between the amount of Fe added to the plating bath and the hardness, and it is clearly seen that the hardness increases with an increase in Fe.

Connect Ni to the anode side, 45~55℃, 1.5~
Under the condition of 3.5A/dm 2 , the base plate is first plated with nickel. Next, W is added to the plating bath in an amount such that the W content in the plating layer is in the range of 5 to 7%, and as time passes, Fe is added until the Fe content in the plating layer reaches the maximum amount. Add it gradually until it reaches 10% to form a Ni-W-Fe ternary composite plating layer.
By gradually increasing the addition of Fe, a Ni--W--Fe eutectoid-strengthened electroplated layer can be obtained.

を比較調査した。Example: On the short side mold base of a continuous casting mold for slab slabs with a cross-sectional shape of 200 mm thick and 1800 mm wide, the conventional normal Ni plating was applied to the upper end of the mold by 0.5 mm and the lower end to 1.5 mm.
A conventional mold in which Cr plating was applied to a thickness of 0.05 mm and a Ni mold according to the present invention.
-W-Fe ternary alloy plating on the lower half of the base
Only within the 400mm area, the coating is applied over normal Ni plating, and the plating thickness is 0.5mm at the upper end of the mold and 1.5mm at the lower end.
We compared and investigated the wear status of a mold that was machined to a thickness of 0.05 mm and further plated with 0.05 mm of Cr after using 400 channels.

倍近く延長された。 As a result of the above comparative test, in the case of a conventional mold in which Cr plating was applied immediately after Ni plating, the exposed copper base on the short side mold base surface was 2 to 15 mm wide and long in the molten steel injection direction from the lower end. In contrast, in the mold according to the present invention, the maximum wear amount was approximately 0.2 mm, and no exposure of the copper substrate was observed at all. The mold according to the present invention continued to be used after that, but ultimately,
1600 channels can be used, and the lifespan is 4 times longer than that of conventional molds.
It was extended nearly twice as long.
