Description

스카핑머신의 연속점화장치{A CONTINUOUS IGNITION DEVICE OF SCARFING MACHINE}Continuous lighting device of scarfing machine {A CONTINUOUS IGNITION DEVICE OF SCARFING MACHINE}

본 고안은 스카핑머신(Scarfing Machine)의 연속점화장치에 관한 것으로, 특히 점화커버를 스케일유입방지판으로 자동 개폐함으로써 비산스케일에 의한 점화플러그의 점화불량을 방지하는 스카핑머신(Scarfing Machine)의 연속점화장치에 관한 것이다.The present invention relates to a continuous ignition device of a scarfing machine (Scarfing Machine), in particular of the scarfing machine (Scarfing Machine) to prevent the ignition failure of the spark plug by the scattering scale by automatically opening and closing the ignition cover with a scale inlet prevention plate It relates to a continuous ignition device.

일반적으로, 제철소 연주공정에서 주조된 슬라브는 그 표면에 발생되는 홈을 제거하기 위하여 정정라인의 스카핑머신을 통과하게 된다.In general, the slab cast in the steel mill playing process is passed through the scarfing machine of the correction line to remove the grooves generated on the surface.

이때, 도1 및 도2에 도시한 바와같이 스카핑작업이 행해지는 슬라브(3)는 롤(4) 상부를 이동하다가 그 선단이 하부핀치롤(5)에 이르면 하강되는 상부핀치롤(6)에 눌리면서 스카핑머신의 내부로 안내된다.At this time, as shown in Figures 1 and 2, the slab (3) where the scarfing operation is performed is moved to the upper roll 4, the upper pinch roll (6) is lowered when the tip reaches the lower pinch roll (5) It is pressed in and guided inside the scarfing machine.

그리고, 슬라브(3)의 선단이 유니트(8)의 하부에 이르러 정지되면, 스카핑작업 1단을 선택하여 점화플러그(14)에 불꽃을 발생시키고, 가스관(13)을 통해 공급되는 가스를 점화시키게 된다.When the front end of the slab 3 reaches the lower part of the unit 8 and stops, the first step of the scarfing operation is selected to generate sparks in the spark plug 14 and to ignite the gas supplied through the gas pipe 13. Let's go.

또한, 하강되는 슈(9)가 슬라브(3)의 상면에 접촉하게 되면 일정높이만큼 상승하게 되고, 측면유니트(2)가 슬라브의 측면에 접촉하게 되면 일정거리만큼 후진하여 정지하게 된다.In addition, when the shoe 9 falling down contacts the upper surface of the slab 3, the shoe 9 rises by a predetermined height, and when the side unit 2 contacts the side surface of the slab, the shoe 9 moves backward by a predetermined distance and stops.

이때, 스카핑작업 2단을 선택하게 되면, 슬라브(3)는 일정거리만큼 후진하여정지되고, 예열가스 및 예열산소가 매니플드(7)를 통해 상하부블럭(10,11)으로 분사된다.At this time, when the second step of the scarfing operation is selected, the slab 3 is stopped by a predetermined distance and stopped, and preheating gas and preheating oxygen are injected into the upper and lower blocks 10 and 11 through the manifold 7.

여기서, 점화상태인 점화커버(12)에 의해 상하부블럭(10,11)으로부터 분사되는 예열가스 및 예열산소가 점화되면서 슬라브(3)의 선단부 모서리를 예열하게 되고, 이 예열작업이 완료되면 슬라브가 진행되면서 스카핑작업이 실시된다.Here, the preheating gas and preheating oxygen injected from the upper and lower blocks 10 and 11 are ignited by the ignition cover 12 which is in the ignition state, thereby preheating the edges of the front end of the slab 3. As we progress, the scarfing work is carried out.

한편, 슬라브(3)의 스카핑이 시작되면, 부산물로 발생되는 용융 및 비산스케일이 고압수관(29)의 고압수와 함께 스모크후드(1)를 통해 스케일피트(미도시)에 집적된다.On the other hand, when the scarfing of the slab 3 starts, the melting and scattering scale generated as a by-product is integrated in the scale fit (not shown) through the smoke hood 1 together with the high pressure water of the high pressure water pipe 29.

그러나, 종래의 스카핑머신은 점화커버(12)가 비산스케일에 그대로 노출되어 있기 때문에 점화플러그(14)와 가스관(13)에 비산스케일이 융착되고, 더욱이 점화플러그에 고압수 등의 비산수가 흡착됨으로써 점화작업이 불가능하고, 이로써 스카핑머신의 휴지가 번번이 발생하며, 슬라브의 품질이 저하되는 문제점이 발생된다.However, in the conventional scarfing machine, since the ignition cover 12 is exposed to the scattering scale as it is, the scattering scale is fused to the ignition plug 14 and the gas pipe 13, and the scattering water such as high pressure water is adsorbed to the ignition plug. As a result, the ignition operation is impossible, and thus, the pause of the scarfing machine occurs once, and the quality of the slab is deteriorated.

본 고안은 점화커버를 스케일유입방지판으로 자동 개폐함으로써 비산스케일에 의한 점화플러그의 점화불량을 방지하고, 점화플러그의 점화상태를 울트라비젼으로 검출하여 스카핑작업을 원활히 수행할 수 있는 스카핑머신의 연속점화장치를 제공함에 그 목적이 있다.The present invention prevents ignition failure of spark plug by scattering scale by automatically opening and closing the ignition cover with scale inflow prevention plate, and can detect the ignition status of spark plug with ultravision and perform the scarfing operation smoothly. The purpose is to provide a continuous ignition apparatus of.
