The residual cutting edges attached to the slab cutting edges produced by the steel making machine are rested on the on-line roller table, and the beam is automatically raised to the upper and lower portions according to a predetermined operation sequence. And by automatically removing the residual cutting edges of the slab cross section by the downward movement, the cutting edges formed essentially at the bottom of the slab cutting surface is automatically removed, thereby preventing the risk of burns by the hot slab and reducing the workload. In addition to reducing, it is possible to improve the quality of the slab and to prevent equipment accidents, thereby significantly improving operation stability and work productivity.
Description
본 고안은 슬래브 단면의 잔류 절단설을 제거하는 장치에 관한 것으로, 특히 제철 연주기에서 주조된 슬래브가 토치 커팅장치(Torch Cutting Machine)에서 절단될 때, 슬래브 절단면 하부에 필수적으로 형성된 절단설을 자동으로 제거하는 슬래브 단면 잔류 절단설 제거장치에 관한 것이다.The present invention relates to a device for removing residual cutting edges of the slab cross section. Especially, when a slab cast in an iron making machine is cut in a torch cutting machine, the cutting edges formed under the slab cutting surface are automatically cut. The present invention relates to a device for removing slab cross-section residual cutting edges.
일반적으로 제철소 연주공장에서 주조되는 슬래브는 수요가의 요구에 따라 5.500㎜∼12,000㎜의 길이로 토치 커팅 머쉰에서 절단하게 되는데, 이때 슬래브 절단면 하부에 필수적으로 형성되는 절단설은 절단설 제거장치(Burr Removel Device)에 의해 제거된 후, 후 공정으로 이송하게 된다.In general, the slab cast in the steel mill performance factory is cut at the torch cutting machine with a length of 5.500 mm to 12,000 mm according to the demand of the demand, wherein the cutting tongue formed at the bottom of the slab cutting surface is a cutting snow removing device (Burr). After removal by the Removel Device), it is transferred to a later process.
그러나 슬래브 절단면의 하부에 필수적으로 형성된 절단설은 절단설 제거장치에 의해 제거작업이 이루어지게 되지만 슬래브 강종, 슬래브 절단면 상태, 토치 커팅 머쉰 상태, 절단설 제거장치의 상태에 따라 완전 제거되지 않는다.However, the cutting tongue formed at the lower part of the slab cutting surface is removed by the cutting tongue removing device, but is not completely removed depending on the slab steel grade, the slab cutting surface state, the torch cutting machine state, and the cutting tongue removing device.
즉, 도 1 은 일반적인 슬래브 단면의 잔류 절단설을 제거하는 작업상태을 도시한 도면인 바, 상기 도 1에 도시한 바와 같이 잔류 절단설은 슬래브(14) 절단면에 올려 붙게 되어 작업자가 직접 치구(16)를 이용하여 잔류 절단설(15)을 제거하게 되된다. 이 경우 열간 슬래브에 의해 화상의 위험이 있고, 작업자가 직접 잔류 절단설을 제거하는 데는 현실적으로 작업에 어려움이 있으며, 또한 슬래브에 잔류 절단설이 붙은 상태로 후공정으로 이송되게 되면 품질에 악영향을 끼칠 뿐 아니라 공정으로 이송중 잔류 절단설이 설비상에 떨어져 설비사고가 발생되어 제품 생산에 막대한 지장을 초래하는 문제점이 있었다.That is, Figure 1 is a view showing a working state to remove the residual cutting tongue of the general slab cross-section, as shown in Figure 1 the residual cutting tongue is attached to the cutting surface of the slab 14, the operator directly jig (16) Residual cutting snow 15 is removed by using. In this case, there is a risk of burns due to hot slab, and it is difficult for the worker to remove the residual cutting snow directly, and the quality is only adversely affected if the slab is transported to the post process with the remaining cutting snow attached. However, there was a problem that the residual cutting snow falls on the facility during the transfer to the process, causing equipment accidents, causing huge disruption to the production of the product.
따라서, 본 고안은 상기한 종래의 문제점을 해결하고자 안출한 것으로서, 제철 연주기에서 생산된 슬래브 절단면에 올려 붙은 잔류 절단설을 온 라인(On-Line) 롤러 테이블(Roller Table) 상에서 소정의 동작 순서에 따라 자동으로 제거하는 슬래브 단면의 잔류 절단설 제거장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above-described problems, and the residual cutting snow attached to the slab cutting surface produced by the steel making machine is placed in a predetermined operation sequence on the on-line roller table. It is an object of the present invention to provide an apparatus for removing residual cutting edges of a slab cross section which is automatically removed accordingly.

When the slab 14 is decelerated and progressed, the slab 14 is simultaneously detected by the slab detection sensor 12b. When the stop signal is generated, the solenoid valve 17a is actuated and the beam 1 rises.
다음 상기 쉬어 빔(1)이 상승함에 따라 센서(11a)에 감지되면 솔레노이드 밸브(17b)가 작동되어 쉬어 피스톤(2)이 전진 작동하여 블래이드(10)가 슬래브(14) 헤드 단면에 밀착되면 솔레노이드 밸브(17a)가 작동되어 쉬어 빔(1)이 하강하도록 한다.Next, when the shear beam 1 rises and the sensor 11a is detected, the solenoid valve 17b is operated to move the shear piston 2 forward so that the blade 10 comes into close contact with the slab 14 head end face. The valve 17a is activated to allow the beam 1 to descend.
상기 쉬어 빔(1)의 하강에 의해 슬래브(14) 헤드 단면에 붙어 있는 잔류 절단설은 제거되고, 쉬어 빔의 하강함에 따라 센서(11b)에 의해 감지되면 슬래브(14)가 정 속도로 이송하게 된다. 그리고 슬래브(14)가 진행되다가 슬래브 테일(Tail)부가 슬래브 감지센서(12c)를 벗어남과 동시에 슬래브(14)가 정지되고, 정지신호가 발생되면 솔레노이드 밸브(17a)가 작동되어 쉬어 피스톤(2)이 후진 작동하여 블래이드(10)가 슬래브(14) 테일(TAIL) 단면에 밀착되면 솔레노이드 밸브(17a)가 작동되어 쉬어 빔(1)이 하강하므로 슬래브(14) 테일의 단면에 붙어 있는 잔류 절단설을 제거하게 된다. 상기 쉬어 빔(1)의 하강에 따라 하강 센서(11b)에 감지되면 슬래브(14)가 정 속도로 다시 이송하는 순서로 슬래브 단면 잔류 절단설 제거 작업을 수행하게 된다.Residual cutting edges attached to the slab 14 head cross section are removed by the lowering of the sheer beam 1, and the slab 14 is transported at a constant speed when sensed by the sensor 11b as the sheer beam descends. do. Then, while the slab 14 proceeds, the slab tail part is out of the slab detection sensor 12c, and the slab 14 is stopped. When the stop signal is generated, the solenoid valve 17a is operated to rest the piston (2). When the blade 10 is in close contact with the end face of the tail 14 of the slab 14, the solenoid valve 17a is operated so that the sheer beam 1 descends, so that the remaining cut edges attached to the end face of the slab 14 tail. Will be removed. When the falling sensor 11b is detected as the shear beam 1 descends, the slab cross section residual cutting snow removal operation is performed in the order in which the slab 14 is transported again at a constant speed.
한편, 쉬어 피스톤(2)이 작동하여 블래이드(10)가 슬래브(14) 단면에 밀착될 때, 쉬어 빔(1) 내부에 순간적으로 상승된 에어 압력은 릴리프 밸브(도 8 의 18a,18b)를 통하여 빠지게 되므로 블래이드(10)와 슬래브(14)의 밀착압력은 항상 일정하게 유지되고, 쉬어 빔(1)의 상부 및 하부로의 승, 하강시 언 밸런스(Unbalance)를 방지하기 위하여 속도 조절 밸브(19a,19b)를 설치하고, 또한, 쉬어 피스톤(2)의 작동 속도를 조정하기 위하여 속도 조절 밸브(도 8의 20a,20b)를 설치한다.On the other hand, when the shear piston 2 is operated so that the blade 10 comes into close contact with the slab 14 end surface, the momentarily elevated air pressure inside the sheath beam 1 causes the relief valve (18a, 18b in FIG. 8) to rise. Since the contact pressure between the blade 10 and the slab 14 is always kept constant, and the speed control valve (Unbalance) to prevent the unbalance during the rise and fall of the top and bottom of the shear beam (1) 19a, 19b are provided, and speed control valves (20a, 20b in FIG. 8) are provided to adjust the operating speed of the shear piston 2.
한편, 도 9는 본 고안에 따른 슬래브 단면 잔류 절단설 제거장치의 동작순서도로서, 상기 본 고안의 작용관계를 도해로 설명한 것이다.On the other hand, Figure 9 is a flow chart illustrating the operation of the slab cross-section residual cutting snow removal apparatus according to the present invention, it will be described by explaining the operation relationship of the present invention.
이상 상술한 바와 같이, 본 고안은 제철 연주기에서 생산된 슬래브 절단면에 붙어 있는 잔류 절단설을 온 라인 롤러 테이블 상에서 쉬어 빔이 소정의 동작 순서에 따라 상부와 하부로 승하강함에 의해 자동으로 제거하는 슬래브 단면의 잔류 절단설을 제거하도록 함으로써 슬래브 절단면의 하부에 필수적으로 형성되는 절단설을 자동으로 제거하게 되므로 열간 슬래브에 의해 화상의 위험요인을 방지하고 작업부하를 감소시킬 뿐 아니라, 슬래브의 품질을 향상시킬 수 있고 설비사고를 방지하여 조업안정 및 작업 생산성을 현저히 향상시킬 수 있는 효과를 얻는다.As described above, the present invention is a slab for removing the residual cutting edge attached to the slab cutting surface produced in the steel making machine automatically by lifting and lowering the beam to the upper and lower parts according to a predetermined operation sequence on the on-line roller table. By removing the residual cutting edges of the end face, the cutting edges formed at the lower part of the slab cutting edge are automatically removed, so that the hot slab not only prevents the risk of burns and reduces the workload, but also improves the quality of the slab. It is possible to improve the operation stability and work productivity by preventing equipment accidents.
