본 발명은 연속주조기의 냉각대 연주롤에 관한 것으로서, 더욱 상세하게는 기존의 강제 수냉에 의한 냉각형태를 그대로 유지하면서 연주롤 내부에 설치 구비되는 냉각수단을 기존 냉각공 형태와 달리하여 연주롤의 열 부하를 감소시킬 수 있는 연속주조기의 냉각대 연주롤에 관한 것이다.The present invention relates to a cooling roll playing roll of a continuous casting machine, and more particularly, the cooling means provided inside the playing roll while maintaining the existing cooling form by forced water cooling is different from the existing cooling hole form. The present invention relates to a cooling roll playing roll of a continuous casting machine capable of reducing heat load.

일반적으로, 롤러 테이블은 제철공정 중 후판공장 ,열연공장, 연속주조 과정에서 생산되는 제품이 압연 또는 정정라인을 거치는 과정에서 성형제품을 안내하며, 슬라브의 평탄도가 불균일하여 압연을 실시하기 전에 대기모드를 유지시켜 주는 기능을 하게 된다.In general, the roller table guides the molded product during the rolling or correction line of the products produced in the plate mill, hot rolling mill, and continuous casting process in the steelmaking process, and the flatness of the slab is uneven to wait before rolling. It will function to maintain the mode.

도 1에서 보듯이, 연속주조기는 용강(10)이 담겨 있는 래들(20), 이 래들(20)과 주형(30) 사이에서 용강(10)저장 및 개재물 부상분리 기능을 담당하는 턴디쉬(40), 슬라브(70)를 요구 형태 및 크기로 응고시키는 주형(30) 및 다수의 세그먼트롤로 조합된 2차 냉각대(50)를 포함하여 구성되어 있다.As shown in Figure 1, the continuous casting machine ladle 20 containing the molten steel 10, the tundish 40 responsible for the molten steel 10 storage and inclusion floating separation function between the ladle 20 and the mold 30. ), A mold 30 for solidifying the slab 70 to a required shape and size, and a secondary cooling table 50 combined with a plurality of segment rolls.

여기에서, 상기 2차 냉각대(50)는 이 냉각대(50)를 통과하는 주조금속이 임의의 위치에서 일정한 두깨의 응고쉘을 유지하도록 노즐에 의한 냉각 및 롤에 의한 약간의 압하를 한다.Here, the secondary cooling stand 50 is subjected to cooling by the nozzle and a slight reduction by the roll so that the cast metal passing through the cooling stand 50 maintains a fixed thickness of solidified shell at an arbitrary position.

이러한 2차 냉각대(50)에 설치되어 사용되는 연주롤(60)는 슬라브의 인발을 담당하는 핀치 연주롤(60)와 슬라브의 벌징(bulging)을 방지하고 정해진 주조방향 으로 슬라브을 안내해 주는 가이드롤 들로 구성되는데, 이 가이드롤 들은 고온의 슬라브과 접촉해 있는 관계로 열부하에 의한 변형을 받기 쉽고 그와 같은 롤들의 열변형은 슬라브품질에 큰 악영향을 끼치게 된다.The playing roll 60 installed and used in the secondary cooling table 50 is a pinch playing roll 60 which is responsible for drawing the slabs and a guide roll which prevents bulging of the slabs and guides the slabs in a predetermined casting direction. Since the guide rolls are in contact with the hot slab, they are susceptible to deformation due to heat load, and the thermal deformation of such rolls greatly affects the slab quality.

따라서, 이러한 문제점을 해소하기 위해 도 2에서 보듯이, 연주롤(60) 내부에 여러가지 형태로 냉각수 통로(61)를 형성하여 이들 냉각수 통로를 통해 냉각수를 순환시키는 방법을 이용하여 연주롤(60)를 냉각시킨다.Therefore, in order to solve such a problem, as shown in FIG. 2, the cooling roll 60 is formed in various forms inside the playing roll 60 by using a method of circulating the cooling water through these cooling water passages. Cool down.

그러나, 이러한 연주롤 냉각 방식은 연주롤의 표면 최고온도만 약간 저하시킬 뿐이고, 특히 슬라브 표면온도가 매우 고온(약 1000℃이상)인 관계로 연주롤의 표면에 크랙이 자주 발생하여 연주롤의 수명이 단축되는 문제점이 있었고, 벌징에 의한 슬라브 결함까지 빈발하는 문제점이 있었다.However, this rolling roll cooling method only slightly lowers the maximum surface temperature of the rolling rolls, and in particular, since the slab surface temperature is very high (about 1000 ° C. or more), cracks frequently occur on the surface of the rolling rolls, and thus the life of the rolling rolls is increased. There was a problem that this shortening, there was a problem that frequent frequent slab defects due to bulging.

즉, 연주롤 내부에 형성된 냉각공에 의한 강제순환 방식만을 사용할 경우 냉각기능이 제한되고, 이로인해 다수개의 냉각공을 설치해야 하였고, 이는 연주롤의 가공단가를 상승시킬 뿐만 아니라 기계적인 강도를 저감시키는 요인이 되는 문제점이 있었다.That is, when only the forced circulation method by the cooling hole formed inside the playing roll is limited to the cooling function, it was necessary to install a plurality of cooling holes, which not only increases the processing cost of the playing roll but also reduces the mechanical strength. There was a problem that caused it to be.

본 발명은 상기와 같은 문제점을 해결하기 위해 제안된 것으로서, 종래의 냉각 롤러테이블에서 발생되는 슬라브의 변형문제와 롤러의 변형으로 인한 공정 트러블을 해결할 수 있도록 다수개의 냉객공을 냉각 롤러테이블의 구공롤러에 적용함과 동시에 장시간의 사용에도 슬라브의 중량과 고열을 견딜 수 있고, 내부품질 상승효과를 얻을 수 있는 연속주조기의 냉각대 연주롤를 마련하는데 그 목적이 있다.The present invention has been proposed to solve the above problems, a plurality of cold hole ball cooling roller table ball rollers to solve the process problems caused by the deformation of the slab and the deformation of the roller generated in the conventional cooling roller table At the same time, the purpose of the present invention is to provide a cooling roll of a continuous caster which can withstand the weight and high heat of the slab even for a long time use, and obtain the synergy effect of the internal casting.

상기의 목적을 달성하기 위한 본 발명에 따른 연속주조기의 냉각대 연주롤은, 연주공정 중 각 공정으로 슬라브를 이송하도록 2개 이상 복수개의 냉각롤이 마련된 롤러테이블과, 상기 연주롤의 중앙부에 길이방향을 따라 이 연주롤의 순환냉각을 위해 그 내부로 관통형성된 공급공과, 상기 연주롤의 내부 둘레면을 따라 길이방향으로 형성된 외측 냉각공과, 상기 냉각수 공급공을 통해 유입된 냉각수가 외측 냉각공으로 이동될 수 있도록 냉각수 공급공을 따라 외측 냉각공 방향으로 사선지게 형성된 연결공을 포함한다.The cooling table playing roll of the continuous casting machine according to the present invention for achieving the above object is a roller table provided with two or more cooling rolls to transfer the slab to each step during the playing step, and the length in the center of the playing roll A feed hole penetrated therein for circulation cooling of the playing roll along a direction, an outer cooling hole formed in a longitudinal direction along an inner circumferential surface of the playing roll, and cooling water introduced through the cooling water supply hole moves to an outer cooling hole It includes a connection hole formed obliquely in the direction of the outer cooling hole along the cooling water supply hole.

이하에서, 본 발명에 따른 연속주조기의 냉각대 연주롤의 구성 및 그에 따른 실시 예를 첨부된 도면을 참조로 더욱 상세히 설명한다.Hereinafter, with reference to the accompanying drawings the configuration of the cooling roll playing roll and the embodiment according to the continuous casting machine according to the present invention will be described in more detail.

본 발명은 공정 대기시간 동안 슬라브 소재의 이송을 도움과 동시에 냉각 성능이 향상된 냉각 롤러테이블의 냉각롤에 관한 것으로서, 도 3은 본 발명에 따른 연속주조기의 냉각대 연주롤의 연주롤 분할 구성을 도시한 도면이고, 도 4는 본 발명에 따른 연속주조기의 냉각대 연주롤의 연주롤의 구성을 도시한 도면이다.The present invention relates to a cooling roll of a cooling roller table which improves cooling performance while simultaneously assisting the transfer of slab material during a process waiting time, and FIG. 3 illustrates a configuration of splitting a playing roll of a cooling roll playing roll of a continuous casting machine according to the present invention. 4 is a view showing the configuration of the playing roll of the cooling roll playing roll of the continuous casting machine according to the present invention.

연속주조 공정에 의해서 제조된 슬라브(70)를 가열로에서 강종에 따른 목표온도로 가열한 후, 조압연기에서 일정한 두께의 슬라브(70)으로 만든 다음 최종 제품의 두께까지 사상압연을 수행한다.After the slab 70 manufactured by the continuous casting process is heated to a target temperature according to the steel grade in the heating furnace, the slab 70 is made of a constant thickness slab 70 in a rough mill and then subjected to finishing rolling to the thickness of the final product.

이러한 과정의 제철공정 중 슬래브(70)가 제조되는 연속주조 혹은 압연공정 중 사상압연 공정과정으로 가기 전 공정 대기시간 동안 슬라브(70) 소재를 이송할 수 있도록 롤러 테이블(600)이 마련된다.The roller table 600 is provided to transfer the slab 70 material during the process waiting time before going to the finishing rolling process during the continuous casting or rolling process in which the slab 70 is manufactured during the steelmaking process of this process.

상기 롤러 테이블(600)의 구성을 이루고 모터(미도시)와 연결되어 회전될 수 있도록 마련된 2개 이상 복수개의 연주롤(610)가 마련된다.Two or more playing rolls 610 are provided to form the roller table 600 and to be connected to and rotate with a motor (not shown).

이 연주롤(610)는 상부로 이송시키는 슬라브(70)가 이동될 때, 슬라브(70)의 중량에 의해 연주롤(610)의 변형을 억제시키도록 본 발명에서는 연주롤(610)를 분할되도록 구성된다.This playing roll 610 is to be divided in the present invention to suppress the deformation of the playing roll 610 by the weight of the slab 70 when the slab 70 to be transferred to the upper portion to be divided. It is composed.

또한, 상기 연주롤(610)가 분할되어 마련됨에 따라 이 연주롤(610)의 변형을 억제함과 동시에 연주롤(610)의 길이 방향의 중앙 부분에 베어링 하우징(700)이 구성된다.In addition, as the playing roll 610 is divided and provided, the deformation of the playing roll 610 is suppressed and at the same time, the bearing housing 700 is formed at the central portion of the longitudinal direction of the playing roll 610.

상기 연주롤(610)의 중심축(620)을 따라 이 중심축(620)의 길이방향으로 이 연주롤(610)의 순환냉각을 위해 냉각수 공급공(630)이 형성된다.Cooling water supply holes 630 are formed along the central axis 620 of the playing roll 610 in the longitudinal direction of the central axis 620 for the circulation cooling of the playing roll 610.

이 냉각수 공급공(630)을 통해 냉각수가 유입됨으로 인해 고온의 슬라브(70)이 그 상부로 지나가게 되더라고 슬라브(70)의 온도에 의해 연주롤(610)에 협착되는 것을 방지하고, 구동롤어(610)의 변형을 방지하게 되는 것이다.As the coolant is introduced through the coolant supply hole 630, the hot slab 70 is prevented from being caught by the playing roll 610 by the temperature of the slab 70 even though the hot slab 70 passes therethrough. It is to prevent the deformation of the 610.

상기 냉각수 공급공(630) 외측 외주면을 따라 외측 냉각공(640)이 형성된다.An outer cooling hole 640 is formed along the outer circumferential surface of the cooling water supply hole 630.

상기 냉각수 공급공(630)을 통해 유입된 냉각수가 외측 냉각공(640)으로 이동될 수 있도록 냉각수 공급공(630)을 따라 외측 냉각공(640) 방향으로 연결공(650)이 형성되고 이 연결공(650)은 2개 이상 다수개가 형성되며 사선지게 형성된다.A connection hole 650 is formed in the direction of the outer cooling hole 640 along the cooling water supply hole 630 so that the cooling water introduced through the cooling water supply hole 630 may be moved to the outer cooling hole 640. Two or more balls 650 are formed obliquely formed.

상기 연결공(650)은 1차적으로 냉각수 공급공(630)을 통해 유입된 냉각수가 이 냉각수 공급공(620)을 따라 외측 방향으로 형성된 외측 냉각공(640) 으로 흘러 들어 가는 것을 가능하게 해줌으로써 연주롤(610)의 외부냉각 성능을 향상시킴과 더불어 기존 냉각공과는 달리 내부 냉각수의 유로간 열교환을 촉진시킬 수 있다.The connection hole 650 primarily allows the coolant introduced through the coolant supply hole 630 to flow into the outer cooling hole 640 formed in the outward direction along the coolant supply hole 620. In addition to improving the external cooling performance of the play roll 610, unlike the existing cooling hole can promote heat exchange between the flow path of the internal cooling water.

또한, 상기 연결공(650)이 외측 냉각공(640)을 향해 사선지게 형성된 것은 냉각수 공급공(620)을 통해 유입된 냉각수가 흐르는 방향으로 보다 쉽게 외측 냉각공(640)으로 유입되기 하기 위함이다.In addition, the connection hole 650 is formed obliquely toward the outer cooling hole 640 to more easily flow into the outer cooling hole 640 in the direction in which the coolant flowing through the cooling water supply hole 620 flows. .

따라서, 상기와 같은 구성으로 이루어진 냉각 성능이 향상된 냉각 롤러테이블의 구동 롤러 장치를 보면, 공정 패스계획에 따라 관련 공정으로 진입하기 이전에 전/후 반복 이송을 하는 동안에도 연주롤(610)가 어느 정도 이하로 변형을 억제하게 되고 슬라브도 그 평탄도를 유지하게 되며, 연주롤(610)의 냉각이 내부 냉각수 순환에 의해서만 이루어지므로 공정 트러블이 최소화되는 작용을 하게 됨과 동시에 기존의 냉각공 형태와 달리 냉각 성능이 더욱 개선된다.Therefore, when the driving roller device of the cooling roller table having the improved cooling performance having the above-described configuration, according to the process pass plan, the performance roll 610 may be rotated even during the repeated transfer before and after entering the related process. Strain is suppressed to less than the degree and the slab also maintains its flatness, and the cooling of the playing roll 610 is made only by the internal cooling water circulation to minimize the process trouble and at the same time unlike the existing cooling hole shape Cooling performance is further improved.

상술한 바와 같이 본 발명에 따른 연속주조기의 냉각대 연주롤에 따르면, 기존의 롤러 테이블을 구성하는 연주롤에 다수의 냉각공을 설치 구비하여 수명을 연장함과 동시에 외부 살수에 의한 산화스케일의 생성 억제를 유도할 수 있어서 슬라브의 품질 및 두깨 감소, 전/후 공정에서의 슬라브 평탄도 불량으로 인한 물류 정체를 해소할 수 있어서 생산성 감소 문제를 해결할 수 있는 효과와, 슬라브 중간단에서의 변형량을 기존 냉각롤 보다도 억제시키게 되어 슬라브 품질불량 및 생산스케줄의 단순화로 설비의 유지보수 비용의 절감화를 꾀할 수 있는 효과가 있다.As described above, according to the cooling roll playing roll of the continuous casting machine according to the present invention, a plurality of cooling holes are provided on the playing roll constituting the existing roller table to prolong the life and to generate an oxidation scale by external watering. Inhibition can be induced to reduce the quality and thickness of the slab, to solve the logistics congestion caused by poor slab flatness in the front and back processes, and to solve the problem of reduced productivity, and the amount of deformation in the middle of the slab Since it is more restrained than the cooling roll, it is possible to reduce the maintenance cost of the facility by reducing the slab quality defect and the production schedule.

또한, 일체형의 내외부 냉각수 통로로 인해 냉각수 간의 열교환 응력을 향상 시켜서 연주롤의 제조 원가를 늦추면서 냉각기능은 더욱 향상시킬 수 있는 효과가 있다.In addition, due to the integral internal and external cooling water passages to improve the heat exchange stress between the cooling water to slow down the production cost of the roll, there is an effect that can further improve the cooling function.
