본 발명은 연속주조에 사용되는 주형을 코팅하는 방법에 관한 것으로, 보다 상세하게는 저융점 원소를 많이 사용하는 미니밀 연속주조나 특수강 연속주조에 주로 사용되는 주형의 표면에 높은 융점의 원소를 코팅하여 내침식성 및 용강과의 반응성을 억제시켜 장수명화를 꾀할 수 있도록 한 내식성이 우수한 연속주조 주형 코팅방법에 관한 것이다.The present invention relates to a method for coating a mold used for continuous casting, and more particularly, by coating an element of high melting point on the surface of a mold mainly used for continuous casting or mini-mill continuous casting using a lot of low melting point elements. The present invention relates to a continuous casting mold coating method having excellent corrosion resistance to suppress corrosion resistance and reactivity with molten steel for long life.

일반적으로, 연속주조(이하 "연주"라 함) 주형은 종래 주괴에 의한 주조에 비하여 생산성이 높고 공정이 단순하여 제어가 용이하므로 그 활용비율이 급신장되고 있음은 물론 그에 관한 기술또한 급속히 발전하고 있다.In general, continuous casting (hereinafter referred to as "casting") molds are more productive and simpler to control than conventional ingot castings, so the utilization ratio is rapidly expanding, and the technology thereof is rapidly developing. have.

특히, 연주 속도가 고속화되고 폭가변기술도 동시에 발달하면서 연주 주형의 수명을 연장시킬 수 있는 기술들이 개발되고 있다.In particular, as the playing speed is increased and the width variable technology is developed at the same time, technologies for extending the life of the playing mold are being developed.

그 중 한가지가 연주 주형의 표면 하단부를 코팅하는 것인데, 종래 연주 주형의 코팅기술중의 하나로 주형내 침동현상에 의한 주편불량방지와 초기 연주조업시 고철과 용강 초기 주입시 급격히 발생하는 용강의 비산현상에 의한 용강이 주형 벽면에 부착되는 융착현상을 방지하기 위해 Ni 도금층 상부에 Cr을 도금한 Ni-Cr 도금이 사용되어 왔다.One of them is to coat the lower surface of the casting mold, which is one of the coating techniques of conventional casting molds. Ni-Cr plating has been used, in which Cr is plated on the Ni plating layer to prevent fusion phenomenon in which molten steel is adhered to the mold wall surface.

그런데, 이러한 코팅 기술은 1970년대 후반에 개발되어 미니밀 연주 주형에서는 최근까지 사용하고 있는 기술로서, Cr 도금은 융점이 철보다 높아 용강의 비산 및 주조중에 발생하는 융착현상을 방지하기 위한 것이지만 이 도금의 특성상 열응력이 강한 연주주형에 두껍게 코팅하기 곤란하여 0.03mm정도 밖에 코팅할 수 없다는 단점을 가진다. However, this coating technology was developed in the late 1970s and has been used until recently in mini-mill casting molds. Cr plating has a higher melting point than iron to prevent fusion during molten steel casting and casting. Due to its characteristics, it is difficult to coat thickly on a casting mold having a high thermal stress, so that it can be coated only about 0.03 mm.

즉, 조업중 응고된 주편과의 마찰과 보수작업에 의한 코팅층 밀링으로 그 효과는 일시적이며, 특히 고철중에 많이 존재하는 저융점 원소(Sn, Zn)에 의한 부분적인 침식작용과 그에 의한 미세한 부분 탈락으로 주형의 수명이 단축되는 단점을 가졌다.That is, the effect of the coating layer milling by friction with the solidified slab during operation and the repair work is temporary, and in particular, partial erosion by low melting point elements (Sn, Zn), which are present in scrap metal, and fine dropout. As a result, the life of the mold was shortened.

뿐만 아니라, 최근의 특수강 연주 비중이 증가하는 추세에 따라 특수강 내에 존재하는 미량원소의 반응에 의한 융착 및 침식현상이 심하게 발생되어 주형의 수명이 급격히 단축되는 문제가 유발되었다.In addition, the recent increase in the proportion of special steel playing caused a severe fusion and erosion caused by the reaction of the trace elements present in the special steel, causing a problem of rapidly shortening the life of the mold.

본 발명은 상술한 바와 같은 종래 기술이 갖는 제반 문제점을 감안하여 이를 해결하고자 창출한 것으로, 보다 높은 융점의 원소를 주형에 코팅하여 미니밀연주나 특수강연주에 사용되는 연주 주형 표면에 효과적인 코팅층을 형성함으로써 내식성에 의한 주형손상을 방지하여 그 사용수명을 연장시킬 수 있도록 한 내식성이 우수한 연속주조 주형의 코팅방법을 제공함에 그 주된 목적이 있다.The present invention was created in view of the above-described problems of the prior art, and by forming an effective coating layer on the surface of the casting mold used for mini-milling or special steel casting by coating the element with a higher melting point on the mold. The main object of the present invention is to provide a coating method of a continuous casting mold having excellent corrosion resistance to prevent mold damage caused by corrosion resistance and to prolong its service life.

본 발명은 상기한 기술적 과제를 달성하기 위하여, 미니밀 또는 특수강 연속주조시 사용되는 주형의 표면에 내식성을 갖추도록 코팅층을 형성하는 코팅방법에 있어서; 양극은 니켈판, 음극은 도금할 주형, 도금용액은 Ni-Sulfamate:333.3g/L(60%용액555.5g/L); CoSO4·7H2O:60g/L; NiBr2:10g/L(50%용액20g/L); Na2WO4·4H2O:4g/L; H3BO3:30g/L; 주석산:10g/L으로 이루어지고, 상기 도금용액중에 Co 및 W의 금속원 시약인 CoSO4와 Na2WO4를 각각 시간당 3.36g/ℓ와 0.3g/ℓ씩 투입하여 소모되는 Co 및 W를 보상하면서 상기 주형 표면에 코팅층을 형성하도록 도금하는 내식성이 우수한 연속주조 주형의 코팅방법을 제공함에 그 특징이 있다.The present invention provides a coating method for forming a coating layer to have corrosion resistance on the surface of the mold used during continuous casting of mini-mill or special steel in order to achieve the above technical problem; Nickel plate for anode, mold for plating for cathode, plating solution for Ni-Sulfamate: 333.3 g / L (60% solution 555.5 g / L); CoSO 4 7H 2 O: 60 g / L; NiBr 2 : 10 g / L (50 g of solution 20 g / L); Na 2 WO 4 · 4H 2 O: 4 g / L; H 3 BO 3 : 30 g / L; Tartaric acid: 10 g / L, and CoSO 4 and Na 2 WO 4 , the metal source reagents of Co and W, are added to the plating solution by 3.36 g / l and 0.3 g / l, respectively, to compensate for Co and W. While providing a coating method of the continuous casting mold excellent in corrosion resistance plating to form a coating layer on the mold surface.

이하에서는, 첨부도면을 참고하여 본 발명에 따른 바람직한 실시예를 보다 구체적으로 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

본 발명은 주형에 있어 내침식성이나 용강과의 반응을 근본적으로 해결하기 위한 방안으로 용강보다 높은 융점의 원소를 주형에 코팅하여 코팅층을 형성하도록 하는 것에 있다.The present invention is to provide a coating layer by coating an element having a higher melting point than molten steel to a mold as a solution to fundamentally solve the corrosion resistance and reaction with molten steel in the mold.

이를 위해, 본 발명에서는 W을 함유한 코팅물질로 Ni-W, Co-W, Ni-Co-W 등을 사용한다.To this end, the present invention uses Ni-W, Co-W, Ni-Co-W and the like as the coating material containing W.

본 발명에서는 이들중 Ni-Co-W를 예시적으로 설명하기로 한다.In the present invention, Ni-Co-W will be described as an example.

이때, 상기 코팅물질을 사용하여 연주 주형에 코팅하는 과정에서 장시간 도금시 발생하는 소모성 도금원의 보상과 그에 따른 주형코팅사양에도 주의를 기울여야 한다.At this time, pay attention to the compensation of the consumable plating source that occurs during the long-time plating in the process of coating the casting mold using the coating material and the mold coating specification accordingly.

예컨대, 하기한 표 1에는 본 발명에서 사용한 Ni-Co-W 도금 사양이 표시되어 있다.For example, Table 1 below shows the Ni-Co-W plating specifications used in the present invention.

아울러, 본 발명에 따른 성분조성을 통해 장시간 도금하였을 때 도금시간에 따른 도금액중 소모되는 Co 및 W의 함량변화는 도 1 및 도 2에 각각 그래프로 나타내었다. 이때, 상기 소모되는 성분의 함량변화는 5 hr마다 측정하였다.In addition, the content change of Co and W consumed in the plating solution according to the plating time when the plating for a long time through the composition of the present invention is shown in the graphs 1 and 2, respectively. At this time, the content change of the consumed components was measured every 5 hr.

순서  order 성분조성 Composition 함량 content 1  One Ni Sulfamate Ni sulfamate 333.3g/L(60%용액 555.5g/L) 333.3 g / L (60% solution 555.5 g / L) 2  2 CoSO4·7H2OCoSO 4 · 7H 2 O 60g/L 60 g / L 3  3 NiBr2 NiBr 2 10g/L(50%용액 20g/L) 10 g / L (50% solution 20 g / L) 4  4 Na2WO4·4H2ONa 2 WO 4 · 4H 2 O 4g/L 4g / L 5  5 H3BO3 H 3 BO 3 30g/L 30 g / L 6  6 주석산 Tartaric acid 10g/L 10g / L

여기서, Co SO4 와 Na2WO4은 도금층 내의 Co, W의 금속원으로서 니켈과 달리 양극에서 보상되지 않으므로 시간에 따라 소모되는 시약이다.Here, Co SO 4 and Na 2 WO 4 are metal sources of Co and W in the plating layer, and unlike nickel, they are reagents that are consumed with time since they are not compensated at the anode.

도 1 및 도 2의 도시와 같이, 본 발명에 따른 조성으로 이루어진 도금용액내에서 양극에는 니켈판(도 1~도 4에 기재되어 있음)을 연결하고, 음극에는 도금하고자 할 주형(몰드)를 연결하여 장시간 도금하였을 경우 도금시간에 따라 도금액중에 소모되는 Co 및 W 금속원 시약에 대해 금속원을 보상해 주었을 경우 도금액 조성이 일정하게 유지되고 있음을 확인할 수 있다.1 and 2, a nickel plate (described in FIGS. 1 to 4) is connected to a positive electrode in a plating solution having a composition according to the present invention, and a mold (mold) to be plated is attached to the negative electrode. In the case of connecting for a long time by plating, when the metal source is compensated for the Co and W metal source reagents consumed in the plating solution according to the plating time, it can be confirmed that the plating solution composition is kept constant.

이러한 소모량은 전착되는 금속량에 비례하므로 도금액량과 도금면적 그리고 전류밀도에 가장 크게 영향을 받기 때문이다.This consumption is proportional to the amount of metal to be electrodeposited, and thus is most affected by the amount of plating solution, plating area and current density.

도 3과 도 4는 0.025㎡의 도금면적을 갖는 시편을 사용하였을 경우 CoSO4 와 Na2WO4를 각각 시간당 3.36g/L, 0.3g/L,보상하였을 경우 도금층중 Co, W 함량의 변화(4 hr마다 측정함)가 있기는 하지만 종래에 비해 그 변화폭이 그리 크지 않음을 알 수 있다.3 and 4 show the change of Co and W content in the coating layer when CoSO 4 and Na 2 WO 4 were used for 3.36 g / L and 0.3 g / L, respectively, when the specimen having a plating area of 0.025 m2 was used. Although measured every 4 hrs), it can be seen that the variation is not so large compared to the conventional art.

이와 같이, 내식성 연주 주형 코팅을 위해서 소모성 금속원의 도금면적과 도금액량에 따라 일정하게 해당 성분을 보상하면서 도금을 실시하면 균일한 조성의 Ni-Co-W 합금도금을 얻을 수 있다.As described above, when the plating is performed while compensating for the corresponding components in accordance with the plating area of the consumable metal source and the plating solution amount, the Ni-Co-W alloy plating having a uniform composition can be obtained.

이하, 본 발명의 실시예에 대하여 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, the Example of this invention is described.

여기에 주조방향에 따라 상부 0.3mm 하부 2.0mm 도금을 하기 위해서 상기에서 제시한 도금액 조성과 도금면적과 도금액량을 고려한 보상량을 아래와 같이 하여 실험하였다.In order to perform plating on the upper 0.3mm and lower 2.0mm according to the casting direction, the compensation amount considering the plating solution composition, plating area and plating liquid amount presented above was tested as follows.

-Na2WO4·4H2O: 0.3x9.2=2.76g/L,5hr-Na 2 WO 4 4H 2 O: 0.3x9.2 = 2.76 g / L, 5 hr

실험결과, 도 5에 나타난 바와 같은 Ni-Co-W에 의해 내식성이 우수한 연주 주형을 제작할 수 있었으며, 도 6과 같이 본 발명 주형을 특수강 연주기에서 기존 수명만큼 사용한 후 탈형시켜 확인한 결과 주형의 상부 및 하단부에 발생하는 침식 및 부식현상이 도시와 같이 거의 변화없음을 알 수 있었다.As a result of the experiment, Ni-Co-W as shown in Figure 5 was able to produce a good corrosion resistance performance mold, as shown in Figure 6 after using the mold of the present invention in the special steel machine for the existing life as a result of the demoulding confirmed the upper and The erosion and corrosion phenomena occurring at the lower end were almost unchanged as shown.

이상에서 상세히 설명한 바와 같이, 본 발명은 연주 주형 도금시 소모성 도금원을 보상해줌으로써 코팅품위가 향상되어 내식성 및 내침식성이 우수하여 그 수명이 연장된 효과를 제공한다.As described in detail above, the present invention improves the coating quality by compensating for the consumable plating source during the performance casting plating, thereby providing an effect of prolonging its life due to its excellent corrosion resistance and corrosion resistance.
