니켈-철 합금도금강판의 제조방법 및 이로부터 제조된 니켈-철 합금도금강판 {METHOD FOR MANUFACTURING OF Ni-Fe ALLOY COATED STEEL SHEET AND Ni-Fe ALLOY GALVANIZED STEEL SHEET BY THE SAME METHOD}FIELD OF THE INVENTION [0001] The present invention relates to a method of producing a nickel-iron alloy plated steel sheet and a nickel-iron alloy plated steel sheet produced from the same. BACKGROUND ART < RTI ID = 0.0 >

본 발명은 정밀기계나 광학기계 부품 등의 소재로 사용되는 니켈-철 합금도금강판을 제조하는 방법 및 이로부터 제조된 니켈-철 합금도금강판에 관한 것이다.
The present invention relates to a method of producing a nickel-iron alloy plated steel sheet used as a material for precision machines and optical machine parts, and a nickel-iron alloy plated steel sheet produced from the method.

니켈(Ni)은 철(Fe)보다 전기화학적으로 귀(貴, noble)한 금속이며 경도도 높아, 이러한 니켈을 이용하여 강판 상에 도금층을 형성하면 내마모성을 향상시킬 수 있다.
Nickel (Ni) is a metal electrochemically noble and has a higher hardness than iron (Fe), and wear resistance can be improved by forming a plating layer on the steel sheet by using such nickel.

이와 같이, 니켈을 도금한 강판은 정밀기계나 광학기계 부품 등으로 주로 사용되는데, 니켈과 철 모두 열팽창계수(α)가 커 실사용에는 많은 제약이 있는 실정이다.
As described above, nickel-plated steel sheets are mainly used for precision machines and optical machine parts, and both nickel and iron have a large thermal expansion coefficient (?

일반적으로, 유리의 열팽창계수(α)가 8.5×10-6/K인 반면, 니켈과 철의 열팽창계수는 각각 13.0×10-6/K, 11.8×10-6/K로 서로 유사한 값을 가지며, 상기 유리에 비해 높다. Generally, the coefficient of thermal expansion (α) of glass is 8.5 × 10 -6 / K, while the coefficients of thermal expansion of nickel and iron are 13.0 × 10 -6 / K and 11.8 × 10 -6 / K, , Which is higher than the glass.

그런데, 인바(Invar) 합금으로 알려진 Ni36%-Fe 합금은 실온에서의 열팽창계수가 1.2×10-6/K로 낮으며, 이로 인해 온도 변화에 따른 치수 변화가 거의 없다. 이에, 인바 합금(Invariable 36 alloy)은 정밀기계, 광학기계의 부품, 시계의 부품과 같이 온도 변화에 의한 치수 변화시 오차의 원인이 되는 기계 부품에 주로 사용될 뿐만 아니라, 표준길이 측정기구, 정밀부품, 추 및 온도조절봉 등 그 용도가 다양하다.
However, the Ni36% -Fe alloy, which is known as Invar alloy, has a low thermal expansion coefficient of 1.2 × 10 -6 / K at room temperature, which causes little dimensional change with temperature change. Invariable 36 alloy is used not only for machine parts which cause errors in dimensional change due to temperature changes such as precision machinery, optical machine parts, and watch parts, but also standard length measuring instruments, precision parts , Weights, and temperature control rods.

한편, 철(Fe)은 수용액 중에서 매우 불안정하여 2가 철 이온이 3가 철 이온으로 쉽게 산화되고, 이 3가 철 이온(ferric ion)은 낮은 pH에서도 산화물이나 수산화물을 만들어 슬러지를 형성하기 때문에, 철 이온을 함유하는 도금욕은 관리하기 어려운 문제가 있다.On the other hand, iron (Fe) is very unstable in an aqueous solution, so that the ferric ion is easily oxidized to a trivalent iron ion, and the ferric ion forms an oxide or a hydroxide at a low pH to form sludge, There is a problem that plating baths containing iron ions are difficult to manage.

이를 방지하기 위한 방안으로서 도금욕의 pH를 1.0 이하로 제어하는 방안이 있으나, pH가 1.0 이하로 너무 낮으면 수소 가스 발생량이 증가하여 음극전류효율이 하락하고, 전압 상승으로 인한 전력비 증대는 물론 발생하는 수소가 모재(소지철)에 흡장하여 재료에 수소취성을 일으키는 문제가 있다.
As a measure to prevent this, there is a method of controlling the pH of the plating bath to 1.0 or less. However, if the pH is too low to 1.0 or less, the amount of hydrogen gas generation increases and the cathode current efficiency decreases. There is a problem that the hydrogen which is stored in the base material (base steel) is occluded, causing hydrogen embrittlement in the material.

따라서, 상기와 같은 문제점을 일으키지 않으면서, 낮은 열팽창계수를 갖는 니켈-철 합금도금강판을 제조할 수 있는 방법에 대해 모색할 필요가 있다.
Accordingly, there is a need to search for a method of manufacturing a nickel-iron alloy plated steel sheet having a low thermal expansion coefficient without causing the above problems.

본 발명의 일 측면은, 외부 열에 의한 치수 변화가 매우 적은 니켈-철 합금도금강판을 제조할 수 있는 최적의 방법과 이로부터 제조된 니켈-철 합금도금강판을 제공하고자 하는 것이다.
An aspect of the present invention is to provide an optimal method for producing a nickel-iron alloy plated steel sheet with very small dimensional change due to external heat and a nickel-iron alloy plated steel sheet produced from the method.

본 발명의 일 측면은, 소지강판을 준비하는 단계; 상기 소지강판 표면에 니켈도금하여 니켈도금강판을 제조하는 단계; 및 상기 니켈도금강판을 강판온도 600~800℃에서 5~10초간 가열하는 단계를 포함하고,According to an aspect of the present invention, there is provided a method of manufacturing a steel sheet, Nickel plating on the surface of the base steel sheet to produce a nickel plated steel sheet; And heating the nickel plated steel sheet at a steel sheet temperature of 600 to 800 DEG C for 5 to 10 seconds,

상기 가열 후 도금층 내의 철(Fe) 함량이 60~70중량%인 니켈-철 합금도금강판의 제조방법을 제공한다.
And the iron (Fe) content in the plating layer after the heating is 60 to 70% by weight.

본 발명의 다른 일 측면은, 상기한 제조방법에 의해 제조된 니켈-철 합금도금강판을 제공한다.
Another aspect of the present invention provides a nickel-iron alloy plated steel sheet produced by the above manufacturing method.

본 발명에 의하면, 낮은 열팽창계수를 가지면서 도금밀착성이 우수한 니켈-철 합금도금강판을 제조할 수 있다.According to the present invention, it is possible to produce a nickel-iron alloy plated steel sheet having a low thermal expansion coefficient and excellent plating adhesion.

또한, 본 발명에 의한 니켈-철 합금도금강판은 정밀기계부품 등의 소재로 적합하게 적용할 수 있는 효과가 있다.
Further, the nickel-iron alloy plated steel sheet according to the present invention can be suitably applied to materials such as precision machine parts.

도 1은 니켈-철 합금도금강판의 도금층 내 Fe 함량에 따른 열팽창계수 값을 그래프로 나타낸 것이다.
FIG. 1 is a graph showing the values of thermal expansion coefficient depending on the Fe content in a plating layer of a nickel-iron alloy plated steel sheet.

본 발명자들은 기존 니켈도금강판의 높은 열팽창계수의 한계를 극복할 수 있는 방안에 대하여 깊이 연구한 결과, 니켈도금강판을 가열하여 도금층 내에 충분한 함량으로 철(Fe)이 함유되도록 하는 경우, 열팽창계수를 효과적으로 낮출 수 있으면서, 도금밀착성도 우수하게 확보할 수 있음을 확인하고, 본 발명을 완성하기에 이르렀다.
The inventors of the present invention have made intensive studies on the way to overcome the limit of the high thermal expansion coefficient of existing nickel plated steel sheets. As a result, when the nickel plated steel sheet is heated to contain iron (Fe) in a sufficient amount in the plated layer, It can be effectively lowered and the plating adhesion can be ensured to be excellent. Thus, the present invention has been accomplished.

이하, 본 발명에 대하여 상세히 설명한다.
Hereinafter, the present invention will be described in detail.

본 발명의 일 측면에서 제공하는 니켈-철 합금도금강판의 제조방법은, 소지강판을 준비하는 단계; 상기 소지강판 표면에 니켈도금하여 니켈도금강판을 제조하는 단계; 및 상기 니켈도금강판을 강판온도 600~800℃에서 5~10초간 가열하는 단계를 포함하며, 상기 방법에 의할 경우 열팽창계수가 낮은 니켈-철 합금도금강판을 제조할 수 있다.
A method of manufacturing a nickel-iron alloy plated steel sheet provided in an aspect of the present invention includes: preparing a base steel sheet; Nickel plating on the surface of the base steel sheet to produce a nickel plated steel sheet; And heating the nickel-plated steel sheet at a steel sheet temperature of 600 to 800 ° C for 5 to 10 seconds. According to the method, a nickel-iron alloy plated steel sheet having a low thermal expansion coefficient can be produced.

본 발명에서 사용되는 소지강판으로는 니켈도금강판을 위한 어떠한 강판도 가능하며, 바람직하게는 열연강판 또는 냉연강판일 수 있으며, 보다 바람직하게는 냉연강판일 수 있다.
The base steel sheet used in the present invention may be any steel sheet for nickel-plated steel sheet, preferably a hot-rolled steel sheet or a cold-rolled steel sheet, and more preferably a cold-rolled steel sheet.

상기 니켈도금강판을 제조하는 단계에서는, 상기 소지강판에 전기도금방식으로 니켈을 전기도금하여 니켈 도금층을 형성하며, 이때 10~30g/m2의 도금층 부착량으로 행해지는 것이 바람직하다.In the step of producing the nickel plated steel sheet, it is preferable that the base steel sheet is electroplated with nickel by an electroplating method to form a nickel plated layer, wherein the plating layer adheres at 10 to 30 g / m 2 .

상기 니켈 전기도금시 도금층 부착량이 10g/m2 미만이면 형성되는 도금층의 두께가 얇아 목표로 하는 낮은 열팽창계수를 얻기 어려워지는 문제가 있으며, 반면 30g/m2을 초과하게 되면 너무 과다한 도금량으로 인해 후속되는 열처리 공정에서 충분한 합금이 이루어지지 않는 문제가 있다.
When the coating amount of the plating layer is less than 10 g / m 2 in the nickel electroplating, there is a problem that the thickness of the formed plating layer is thin and it is difficult to obtain a desired low thermal expansion coefficient. On the other hand, when the coating amount exceeds 30 g / m 2 , There is a problem that a sufficient alloy is not formed in the heat treatment step.

상기한 바에 따라 제조된 니켈도금강판을 이용하여 가열처리한다. 상기 가열처리 공정은 본 발명에서 핵심이 되는 공정으로서, 상기 니켈도금강판을 고온에서 가열처리함으로써 합금화된 도금강판을 제조할 수 있으며, 특히 본 발명에서 의도하는 니켈-철 합금도금강판을 제조할 수 있다. The nickel-plated steel sheet produced in the above-mentioned manner is used for heat treatment. The heat treatment process is a key process in the present invention. The nickel-plated steel sheet can be subjected to heat treatment at a high temperature to produce an alloyed coated steel sheet. In particular, the nickel- have.

이때, 상기 가열처리는 상기 니켈도금강판의 온도가 600~800℃를 만족하는 온도범위에서 5~10초간 실시하는 것이 바람직하다.At this time, it is preferable that the heat treatment is performed for 5 to 10 seconds in the temperature range of the nickel plated steel sheet satisfying the temperature of 600 to 800 deg.

상기 니켈도금강판의 온도가 600℃ 미만이거나 가열시간이 5초 미만이면 합금화 반응이 충분치 못하여 의도하는 합금도금강판을 얻기 어려워지며, 반면 800℃를 초과하게 되거나 가열시간이 10초를 초과하게 되면 합금화가 너무 과도하게 일어나 도금층이 매우 취약해져 크랙(crack) 등의 발생이 쉬워지며, 도금강판 자체의 기계적 성질이 변하게 될 우려가 있다. If the temperature of the nickel-plated steel sheet is less than 600 ° C or the heating time is less than 5 seconds, the alloying reaction becomes insufficient and it becomes difficult to obtain the intended alloy-plated steel sheet. On the other hand, when the temperature exceeds 800 ° C or the heating time exceeds 10 seconds, Is excessively excessive, the plated layer becomes very fragile, cracks and the like easily occur, and the mechanical properties of the plated steel sheet itself may change.

또한, 상기 가열처리 공정은 상기 니켈도금강판을 가열할 수 있는 어떠한 가열 방법을 적용하여도 무방하며, 예를들면 고주파 가열, 저항 가열, 전도 가열 및 급속 가열 중 하나의 가열 방법을 이용할 수 있으며, 이중 저항 가열 또는 급속 가열을 이용하는 것이 보다 바람직하다.
The heating process may be any heating method capable of heating the nickel plated steel sheet. For example, one of a high-frequency heating, a resistance heating, a conduction heating, and a rapid heating may be used. It is more preferable to use double resistance heating or rapid heating.

상술한 조건을 만족하여 가열처리 공정을 행함으로써 제조된 니켈-철 합금도금강판의 도금층 내 철(Fe) 함량은 60~70중량%를 만족하는 것이 바람직하다.It is preferable that the iron (Fe) content in the plating layer of the nickel-iron alloy plated steel sheet produced by performing the heat treatment process satisfying the above-mentioned condition satisfies 60 to 70% by weight.

도금층 내 철 함량이 60중량% 미만이면 니켈-철 합금도금강판의 열팽창계수를 효과적으로 낮출 수 없으며, 반면 70중량%를 초과하게 되면 도금밀착성이 급격하게 나빠지는 문제가 있다.
If the content of iron in the plating layer is less than 60% by weight, the coefficient of thermal expansion of the nickel-iron alloy coated steel sheet can not be effectively lowered. On the other hand, if the content of iron exceeds 70% by weight, the plating adhesion is drastically deteriorated.

상술한 바와 같이, 본 발명에서 제공하는 제조방법을 이용할 경우 낮은 열팽창계수를 갖는 니켈-철 합금도금강판을 제조할 수 있으며, 바람직하게는 5.0×10-6~6.0×10-6/K의 열팽창계수를 갖는 니켈-철 합금도금강판을 제조할 수 있다.
As described above, a nickel-iron alloy plated steel sheet having a low thermal expansion coefficient can be produced by using the manufacturing method provided by the present invention, and preferably, the thermal expansion coefficient of 5.0 × 10 -6 to 6.0 × 10 -6 / K A nickel-iron alloy plated steel sheet having a coefficient can be produced.

이하에서는, 본 발명에 따른 바람직한 일 구현례에 의해 제조된 니켈-철 합금도금강판에 대하여 상세히 설명한다.
Hereinafter, a nickel-iron alloy plated steel sheet manufactured according to a preferred embodiment of the present invention will be described in detail.

본 발명의 다른 일 측면에 따른 니켈-철 합금도금강판은 소지강판 및 상기 소지강판 상에 형성된 니켈-철 합금층을 포함한다.A nickel-iron alloy plated steel sheet according to another aspect of the present invention includes a base steel sheet and a nickel-iron alloy layer formed on the base steel sheet.

이때, 소지강판으로는 니켈도금강판을 위한 어떠한 강판도 가능하며, 바람직하게는 열연강판 또는 냉연강판일 수 있으며, 보다 바람직하게는 냉연강판일 수 있다.
At this time, as the base steel sheet, any steel sheet for the nickel-plated steel sheet may be used, preferably a hot-rolled steel sheet or a cold-rolled steel sheet, and more preferably a cold-rolled steel sheet.

본 발명의 니켈-철 합금도금강판은 소지강판 표면에 니켈-철 합금층을 포함하며, 상기 니켈-철 합금층 내 철(Fe) 함량이 60~70중량%로서, 5.0×10-6~6.0×10-6/K의 낮은 열팽창계수를 가질 수 있다.
Of the present invention, a nickel-iron alloy-plated steel sheet to hold the steel sheet surface a nickel-iron alloy comprises a layer, the nickel-iron alloy layer in the iron (Fe) content of a 60 to 70 wt%, 5.0 × 10 -6 ~ 6.0 X 10 < -6 > / K.

상술한 바와 같이, 낮은 열팽창계수를 갖는 본 발명의 니켈-철 합금도금강판은 온도 변화에 따른 치수 변화가 적어 정밀기계부품 등에 적합하게 이용할 수 있는 효과가 있다.
As described above, the nickel-iron alloy plated steel sheet of the present invention having a low coefficient of thermal expansion has a small dimensional change due to a change in temperature and has an effect of being suitably used for precision machine parts and the like.

이하, 실시예를 통하여 본 발명을 보다 구체적으로 설명하고자 한다. 다만, 하기의 실시예는 본 발명을 예시하여 보다 상세하게 설명하기 위한 것일 뿐, 본 발명의 권리범위를 한정하기 위한 것이 아니라는 점에 유의할 필요가 있다. 본 발명의 권리범위는 특허청구범위에 기재된 사항과 이로부터 합리적으로 유추되는 사항에 의해 결정되는 것이기 때문이다.
Hereinafter, the present invention will be described more specifically by way of examples. It should be noted, however, that the following examples are intended to illustrate the invention in more detail and not to limit the scope of the invention. The scope of the present invention is determined by the matters set forth in the claims and the matters reasonably inferred from them.

먼저, C: 0.11중량%, Mn: 0.43중량%, P: 0.31중량%, S: 0.35중량%, 잔부 Fe 및 기타 불가피한 불순물을 포함하고 두께 0.7mmt의 냉연강판에 대해 부착량 10, 20, 30g/m2으로 니켈 전기도금을 실시하여 전기니켈도금강판을 제조하였다. 이때, 니켈 전기도금은 통상의 방법으로 실시하였다.20, 30 g / m < 2 > was applied to a cold-rolled steel sheet containing 0.11 wt% of C, 0.43 wt% of Mn, 0.31 wt% of P, 0.35 wt% of S, the balance Fe and other unavoidable impurities, m < 2 > to obtain an electroplated nickel-plated steel sheet.

이후, 상기 제조된 전기니켈도금강판을 75×150mm의 크기로 5매씩 절단한 다음, 저항가열 방식으로 강판온도 500℃, 600℃, 700℃, 800℃, 850℃에서 5~15초 동안 각각 가열하여 합금화된 도금강판을 제조하였다.

상기 표 1에 나타낸 바와 같이, 본 발명에 따른 방법으로 제조한 발명예 1 내지 9의 니켈-철 합금도금강판은 도금층 내 Fe 함량이 60중량% 이상으로 Fe가 도금층에 충분히 함유됨으로써, 열팽창계수가 모두 6.0×10-6/K 이하이고, 도금밀착성도 양호한 것을 확인할 수 있다.
As shown in Table 1, the nickel-iron alloy coated steel sheets of Inventive Examples 1 to 9 manufactured by the method according to the present invention had a Fe content of 60% by weight or more in the plating layer, and Fe was sufficiently contained in the plating layer, It was confirmed that all of them were 6.0 x 10 < -6 > / K or less and the plating adhesion was good.

반면, 너무 짧은 시간 동안 가열처리한 비교예 1과 너무 긴 시간 동안 가열처리한 비교예 2는 각각 도금층 내 Fe 함량이 불충분하거나 너무 과도하여 열팽창계수가 높게 나타났으며, 비교예 2의 경우 도금밀착성도 열위한 것을 확인할 수 있다.On the other hand, in Comparative Example 1 which was heat-treated for too short time and Comparative Example 2 which was heat-treated for an excessively long time, the Fe content in the plating layer was insufficient or excessively high and the coefficient of thermal expansion was high. It is also possible to confirm that it is to open.

또한, 너무 높은 온도로 가열처리한 비교예 3 및 4의 경우에도 도금층 내 Fe 함량이 너무 과도하여 열팽창계수가 충분히 낮춰지지 못하였으며, 도금밀착성이 매우 열위하였다.Also, in the case of Comparative Examples 3 and 4 which were subjected to heat treatment at an excessively high temperature, the Fe content in the plating layer was excessively excessive, the coefficient of thermal expansion could not be sufficiently lowered, and the plating adhesion was extremely poor.

그리고, 너무 낮은 온도에서 너무 긴 시간 동안 가열처리한 비교예 5와 동일 온도에서 너무 짧은 시간 동안 가열처리한 비교예 6의 경우에는 도금층 내 Fe 함량이 40중량% 이하로 합금화가 충분히 일어나지 못한 것을 확인할 수 있으며, 이로 인해 열팽창계수가 높은 것을 확인할 수 있다.
In the case of Comparative Example 6 which was heat-treated at the same temperature as that of Comparative Example 5 which was heat-treated at an excessively low temperature for a too short period of time, the Fe content in the plating layer was found to be not more than 40 wt% And it is confirmed that the thermal expansion coefficient is high.

한편, 비교재로서 사용한 비교예 7의 경우에는 상기 비교예 1 내지 6에 비해 열팽창계수가 더 높은 것을 확인할 수 있으며, 또한 본 발명에 따른 발명예 1 내지 9는 상기 비교예 7에 비해 열팽창계수가 1/2 정도로 낮아진 것을 확인할 수 있다.
On the other hand, in the case of Comparative Example 7 used as a comparative material, it can be seen that the thermal expansion coefficient is higher than those of Comparative Examples 1 to 6, and Examples 1 to 9 according to the present invention have a thermal expansion coefficient 1/2. ≪ / RTI >

도 1은 상기 발명예 및 비교예들의 도금층 Fe 함량과 열팽창계수의 관계를 나타낸 것으로서, 도금층 내 철(Fe)이 60~70중량%로 함유될 때 낮은 열팽창계수를 갖는 것을 확인할 수 있다.FIG. 1 shows the relationship between the Fe content of the plating layer and the thermal expansion coefficient of the inventive and comparative examples, and it is confirmed that the coefficient of thermal expansion has a low coefficient of thermal expansion when the iron (Fe) content in the plating layer is 60 to 70% by weight.
