일반적으로 압연기의 압연롤은 슬라브재를 압연하면, 압연부분만이 마찰하여 비압연부분과의 단차(periphery difference)가 생겨 버린다. 이 때문에 폭넓은 슬라브에서부터 폭이 좁은 슬라브로 순번을 달아 압연하는등 압연상 제약이 있었다. 이 문제를 해결하기 위해 많은 온라인 압연롤 연삭장치에 관한 기술과 그 제어방법이 제안되었다.In general, when the rolling roll of the rolling mill rolls the slab material, only the rolled portion is rubbed, resulting in a difference (periphery difference) with the non-rolled portion. For this reason, there were limitations in rolling, such as rolling in sequence from wide slabs to narrow slabs. To solve this problem, a number of online rolling roll grinding devices and their control methods have been proposed.

Be configured to act as an elastomer itself; The on-line rolling roll grinding device changes the inclination of the rail frame with respect to the stand while maintaining the moving direction of the grinding wheel when the grinding unit moves along the rail frame in parallel with the axis of the rolling roll. An on-line rolling roll grinding device is disclosed which further has a rail tilt moving means.

그러나 상기 종래기술은 압연롤을 균일하며 효율적으로 연삭할 수 없는 단점이 있었다.
However, the prior art has a disadvantage in that the rolling roll cannot be ground uniformly and efficiently.

The technology is open to the public.

그러나, 상기와 같이 합성수지재 결합재는 연삭용 숫돌의 사용수명이 짧다는 단점이 있다.      However, the synthetic resin binder as described above has the disadvantage that the service life of the grinding wheel is short.

본발명을 첨부도면에 의해 상세히 설명하면 다음과 같다. 도 1은 본발명 온 라인 롤 연삭숫돌이 연삭숫돌축에 결합된 사진, 도 2는 본발명 온 라인 롤 연삭숫돌 정면 사진, 도 3은 본발명 온 라인 롤 연삭숫돌 배면 사진, 도 4는 도3의 상세 사진, 도 5는 본발명 온 라인 롤 연삭숫돌 측면 사시 사진이다.
The present invention will be described in detail with reference to the accompanying drawings. 1 is a photograph of the present invention on-line roll grinding wheel coupled to the grinding wheel shaft, Figure 2 is the present invention on-line roll grinding wheel front photo, Figure 3 is the present invention on-line roll grinding wheel back photo, Figure 4 is Figure 3 5 is a detailed on-line roll grinding wheel side perspective photograph of the present invention.

본발명은 온 라인 롤 연삭숫돌은 면판(10)과, 상기 면판(10) 전면에 방사상으로 결합되는 다수 개의 연삭부재(20)로 구성된다. 상기 면판은 알루미늄 재질로 제작된 것으로, 중앙에 축고정 구멍이 형성된 원형판 형상이다.     The present invention is an online roll grinding wheel is composed of a face plate 10 and a plurality of grinding members 20 radially coupled to the front face of the face plate 10. The face plate is made of aluminum, the shape of a circular plate formed with a shaft fixing hole in the center.

그리고 상기 연삭부재는 곡선형상으로 제조된 것으로, 동일한 형상으로 제조되어, 방사상으로 면판 전면에 부착된다. 그리고 다수 개의 연삭부재가 중심점을 기준으로 방사상으로 배치되되, 상기 연삭부재의 가운데 부위는 빈공간이 형성된다. 상기 연삭부재를 면판에 부착하는 것은 접착제에 의해 부착한다.      In addition, the grinding member is manufactured in a curved shape, is manufactured in the same shape, and is attached radially to the front of the face plate. And a plurality of grinding members are disposed radially with respect to the center point, the hollow portion is formed in the center of the grinding member. Attaching the grinding member to the face plate is attached by an adhesive.

한편, 본발명은 상기 다수 개의 연삭부재를 면판상면에 방사상으로 부착하되, 서로 이격되게 설치한다. 그러므로 상기 연삭부재(20)와 연삭부재(20) 사이에는 이격홈(30)이 형성되어 상기 이격홈(30)을 통하여 연삭액 및 연삭찌꺼기가 용이하게 유출되는 것이다. 연삭부재는 4개가 적정하며, 짝수로 정한다. 이격간격은 지름의 1/1000 ~ 2/1000로 한다. 이격간격인 이격홈의 폭이 1/1000보다 좁으면 연삭액 및 연삭찌꺼기의 유출에 지장이 있고, 2/1000보다 넓으면 연삭력이 떨어지며, 연삭이 불균일 하게 될 우려가 있다. 그리고 연삭숫돌 지름이 1000mm이고, 연삭부재가 4개일 경우 이격홈의 폭은 1.7mm가 적정하다.     On the other hand, the present invention is attached to the plurality of grinding members radially on the face plate upper surface, it is installed spaced apart from each other. Therefore, the separation groove 30 is formed between the grinding member 20 and the grinding member 20, the grinding fluid and the grinding residue easily flows out through the separation groove (30). Four grinding members are appropriate and shall be set to an even number. The separation interval is 1/1000 to 2/1000 of the diameter. If the width of the separation gap is smaller than 1/1000, there is a problem in the outflow of the grinding fluid and the grinding residue, and if it is wider than 2/1000, the grinding force falls, there is a fear that the grinding is uneven. And grinding wheel diameter is 1000mm, when the grinding member is four, the width of the separation groove is appropriate 1.7mm.

한편, 상기 이격홈(30)은 곡선으로 형성하고, 외주방향으로 갈수록 단면이 크게 형성되게 할 수 있다. 이는 연삭숫돌이 회전하므로, 원심력이 큰 외주방향으로 갈수록 이격홈을 넓게 한다. 그리고 곡선방향은 중심에서 외주쪽 이격홈이 연삭숫돌 회전반대방향으로 향해 있게 한다. 이는 마치 공기저항을 적게한 횡류팬 날개구조와 같은 이치이다.
On the other hand, the separation groove 30 may be formed in a curve, the cross section is formed to be larger toward the outer circumferential direction. Since the grinding wheel rotates, the separation groove widens toward the outer circumferential direction where the centrifugal force is large. And the curved direction allows the outer peripheral groove from the center to face the grinding wheel in the opposite direction. This is the same as the crossflow fan blade structure with low air resistance.

한편, 상기 온 라인 롤 연삭숫돌의 연삭부재(20)의 연삭입자는 탄화규소(SiC)이며, 결합제는 구리 및 니켈이며, 또한 보조첨가제로서 비정질탄소를 포함한다. 상기 연삭숫돌의 성분함량은 탄화규소 5 ~ 13중량부에 대하여, 니켈 6 ~ 14중량부, 구리 6 ~ 14중량부, 비정질탄소 43 ~ 49중량부로 이루어진다.    On the other hand, the grinding particles of the grinding member 20 of the online roll grinding wheel are silicon carbide (SiC), the binder is copper and nickel, and also contains amorphous carbon as an auxiliary additive. The content of the grinding wheel is composed of 6 to 14 parts by weight of nickel, 6 to 14 parts by weight of copper, and 43 to 49 parts by weight of amorphous carbon, based on 5 to 13 parts by weight of silicon carbide.

온 라인 롤 연삭숫돌의 연삭부재(20)내 탄화규소의 함량이 5 중량부 미만이면 숫돌 사용수명이 짧아지고, 함량이 13중량부를 초과하면, 스톡제거율이 감소한다.When the content of silicon carbide in the grinding member 20 of the online roll grinding wheel is less than 5 parts by weight, the grindstone life is shortened, and when the content exceeds 13 parts by weight, the stock removal rate decreases.

그리고 결합재인 니켈과 구리는 동일하게 6 ~ 14중량부를 첨가하며, 6중량부 미만이면, 상대적으로 결합력이 떨어지며, 14 중량부를 초과하면 상대적으로 연삭입자의 함량이 적어져 연삭숫돌의 수명이 떨어진다.     And the same amount of nickel and copper as the binder is added 6 to 14 parts by weight, less than 6 parts by weight, the bonding strength is relatively low, if more than 14 parts by weight of the relatively low content of grinding particles, the life of the grinding wheel is reduced.

또한, 비정질 탄소의 함량이 43중량부 미만이면, 연삭용 숫돌의 자생력이 떨어지며 연삭 동안에 들러붙음이 발생하기 쉽고, 49중량부를 초과하면 결합상 경도는 향상되나 연삭용 숫돌의 사용수명이 짧아진다.
In addition, when the content of amorphous carbon is less than 43 parts by weight, the self-supporting force of the grinding wheel is lowered and sticking easily occurs during grinding. When it exceeds 49 parts by weight, the bonding phase hardness is improved, but the service life of the grinding wheel is shortened.

그리고 본발명에서 상기 원료들을 혼합한 후 압축성형하기 위해 숫돌형상의 금형내에 주입하고 성형한다. 그리고 압축성형에 의해 형성된 성형품을 소결하며, 소결온도는 600 ~ 1200 ℃정도로 한다. 소결온도가 600℃ 미만이면, 소결이 완전히 되지 않으며, 1200 ℃가 초과하면, 연삭입자나 결합제가 산화되는 단점이 있다.
In the present invention, the raw materials are mixed and injected into a grindstone-shaped mold for compression molding. And the molded article formed by compression molding is sintered, and sintering temperature shall be about 600-1200 degreeC. If the sintering temperature is less than 600 ℃, the sintering is not completely, if the 1200 ℃ exceeds, there is a disadvantage that the grinding particles or binder is oxidized.

따라서 본발명의 연삭숫돌은 인성과 절삭성이 뛰어나며 강도가 강하며, 또한 압연롤을 균일하며 효율적으로 연삭할 수 있는 현저한 효과가 있다.     Therefore, the grinding wheel of the present invention is excellent in toughness and machinability, strong in strength, and also has a remarkable effect of uniformly and efficiently grinding rolling rolls.
