Description
본 발명은 가열로의 입측에 설치된 실롤(Seal Roll)의 콘트롤장치에 관한 것으로, 특히 스트립 자중에 의해 하부 실롤에 부하되는 과부하 방지 및 실롤 표면에 발생되는 고열에 의한 조기소손 등을 방지하고, 진행되는 스트립 폭에 의해 상, 하부 실롤 간격이 자동 제어될 수 있도록 하는 장치에 관한 것이다.The present invention relates to a control device of a seal roll installed at the inlet side of a heating furnace. In particular, the present invention relates to preventing overloading of the lower seal roll by strip weight and preventing premature burnout due to high heat generated on the surface of the seal roll. An apparatus is provided so that the upper and lower seal roll intervals can be automatically controlled by the strip width to be obtained.
일반적으로, 용융아연 공정은 열연의 핫 코일을 소재로 하여, 코일 대형화 및 스케일 제거작업을 실시하고, 이후 사이드 트리밍을 실시하게 하여, 바로 오일링 처리작업으로 완성하는 산세강판과 가열로를 경유하여 도금작업을 실시하는 용융아연 도금강판제품으로 구분 생산하게 되는 것이다.In general, the hot-dip galvanizing process uses hot rolled hot coils as a material for coil enlargement and descaling, followed by side trimming, via pickling steel plates and heating furnaces, which are completed by oiling. It will be produced separately by hot-dip galvanized steel sheet that performs plating work.
그런데, 상기 도금 작업을 하기 위해서는 가열로의 라디언 튜브 등에 의해 430±30℃정도로 스트립(S)을 가열하여 용융아연 도금조를 통과하도록 하는 도금작업이 이루어지며, 상기 도금작업이 완성된 스트립(S)은 계속 후공정으로 진행하여 수요가의 주문코일로 완성되어지는 것이다.However, in order to perform the plating operation, a plating operation is performed in which a strip S is heated to about 430 ± 30 ° C. by a radiant tube of a heating furnace so as to pass through a molten zinc plating bath. S) continues with the post-process to complete the order coil of demand price.
이러한 스트립(S)은 용융아연도금공정에서 도금작업이 될 수 있도록 스케일 제거 및 사이드 트리밍을 실시 후 스트립(S)을 가열로(10) 인입작업시 상기 가열로(10)내에는 항시 고온의 열원 분위기가 형성되어 있으므로, 이를 외부로 최대한 방출되지 않도록 기존에 실롤(21)(21a)이 설치되어 롤에 의한 실링이 이루어지고 있으나, 공정상의 소재 두께가 1.4t~4.5t 까지 작업이 이루어져야 하므로 스트립(S) 자중에 의해 하부 실롤(21a)의 과부하발생으로 라인(Line) 스톱(Stop)의 원인이 빈번히 발생되고, 장시간 라인이 스톱된다고 하여도 상기 실롤은 가열로(10)내의 온도가 상온 이하로 떨어질 때까지 계속하여 구동되고 있으므로 정지된 스트립(S) 표면 및 마찰부위가 마모되는 현상과 가열로(10) 내부에서 빠져나오는 열원에 의해 상,하부 실롤(21)(21a) 표면이 잦은 밴딩에 의한 롤 소손 등으로 잦은 롤 교체작업이 발생되고 있으며, 정상 작업중 작업자가 스트립(10) 두께에 따라 자주 간격조정을 실시해야 하므로 간격조성시 위험한 작업여건 발생과 안전 사고가 잔존되어 있는 문제점들이 있는 것이다.The strip (S) is a hot heat source at all times in the heating furnace (10) when the strip (S) is introduced into the heating furnace (10) after the scale removal and side trimming so as to be a plating operation in the hot dip galvanizing process Since the atmosphere is formed, the seal rolls (21) (21a) has been installed in the past so as not to be discharged to the outside as much as possible, but the sealing is made by the roll, but the material thickness in the process should be made to 1.4t ~ 4.5t strip (S) The cause of line stop occurs frequently due to overload of the lower seal roll 21a due to its own weight, and even though the line is stopped for a long time, the temperature in the furnace 10 is lower than room temperature. The van is frequently driven by the surface of the suspended strip (S) and the friction part and the surface of the upper and lower silols (21, 21a) due to the heat source coming out from the inside of the furnace (10). There are frequent roll replacements due to roll burnout, and there are problems that dangerous work conditions and safety accidents remain during the construction of the gap because the operator must frequently adjust the gap according to the thickness of the strip 10 during normal operation. will be.

Auxiliary devices by installing overload prevention rolls 51, bearing blocks 52, 52a, and fixtures 53, 53a in front of the lower silol so that the phenomenon is minimized and the position is always set constant regardless of strip thickness. 50, working Spray nozzles 41 and 41a on the upper and lower roll sides using bolts 45 on the roll fixing bodies 22 and 22a to prevent damage to the upper and lower silol surfaces due to the high heat emitted from the furnace. ), And supply pipes 42 and 42a, manual valves 43 and 43a for control, and automatic control valve 44 to form a cooling device 40 to form a control unit body A. It was done.
이와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.
용융도금작업이 이루어질 수 있도록 산세처리 되어 진행되는 스트립을 가열로에서 스트립 표면에 열원을 부여키 위한 작업을 실시중 작업소재가 1.4t~4.5t 까지 다양하게 작업이 실시되어진다.In order to apply the heat source to the surface of the strip in the heating furnace, the work is picked up from 1.4t to 4.5t in various ways.
이러한 작업소재 두께 차이를 본 발명에 따른 가열로 입측 실롤콘트롤 장치에 의해 자동으로 해결할 수 있는데, 우선 작업소재인 진행되는 스트립 폭 데이터를 데이터 전송장치(3b)에 의해 전,후행 스트립(S) 연결부위를 중심으로 전동모터(35)를 적정량 회전시킴으로서 상부 실롤을 스트립(S) 표면과 맞닿지 않을 정도로까지 간격을 조절하게 된다.This work material thickness difference can be automatically solved by the furnace silo control device according to the present invention. First, the progress strip width data, which is the work material, is connected to the front and trailing strips S by the data transmission device 3b. By rotating the electric motor 35 around an appropriate amount, the gap is adjusted to such an extent that the upper silol does not come into contact with the surface of the strip S.
즉, 상기 전동모터(35)를 적정량 회전시키면 그 전동모터(35)의 축에 고정된 스프라켓(33)을 적정량 회전하고, 상기 스프라켓(33)과 체인(34)의 회전에 의해 나사축(31)(31a)의 일측면을 회전시키면서 연결대(32)가 회전되어 진행되는 스트립 두께에 알맞게 상부 실롤을 업(Up), 다운(Down) 시킴으로써 간격조절을 자동으로 하게 되어 지며, 하부 실롤은 항상 1.4t~4.5t 동일한 위치에 일정한 위치를 유지하여 하부 실롤의 과부하 방지를 위해 하부롤 전방에 과부하 방지롤(51)과 베어링블록(52)(52a)을 설치하고, 이를 고정대(53)(53a)에 장착하게 하여 진행되는 스트립(S) 방향으로 회전하게 하여 라인 일시정지시나 작업중 스트립(S) 자중에 의한 하부 실롤에 가중되는 과부하를 방지하고 항상 일정한 스트립(S)과 하부 실롤간의 간격을 고저유지될 수 있도록 하였다.That is, when the electric motor 35 is rotated by an appropriate amount, the sprocket 33 fixed to the shaft of the electric motor 35 is rotated by an appropriate amount, and the screw shaft 31 is rotated by the rotation of the sprocket 33 and the chain 34. Rotating one side of the (31a) while the connecting rod 32 is rotated to adjust the gap by automatically up (Down) the upper seal roll (Up) and Down (down) to suit the thickness of the strip proceeds, the lower seal roll is always 1.4 t ~ 4.5t Install the overload prevention roll 51 and the bearing blocks 52, 52a in front of the lower roll to prevent the overload of the lower seal roll by maintaining a constant position at the same position, and the fixing base 53, 53a. Rotation in the direction of the strip (S) to prevent the overload caused by the line pause or the weight of the lower silol due to the weight of the strip (S) during operation, and always maintain a constant gap between the strip (S) and the lower silol It could be.
그리고, 가열로 입측 실롤측은 항상 고열의 열원이 근접하여 있다보니 실롤 표면에 가중되는 열에 의한 손상을 방지토록 상,하부 실롤 표면 각각에 분사용 노즐(41)(41a) 분사구로 상온이하(5℃이하)의 질소(N2)를 통입토록 공급관(42)(42a)과 수동식 밸브(43)(43a)를 상,하부에 설치하게 하며, 자동밸브(44)에 의해 자동 콘트롤로 분사하므로써 작업중 발생되는 실롤 표면에 냉각하는 방식으로 소재의 두께 차이에 따라 자동 간격 조절 및 노 분위기 안정에 따른 품질향상과 롤 조기소손방지, 실롤 과부하방지로 조업안정이 가능하다.Since the heat source entrance silol is always close to the heat source, the temperature is lower than room temperature (5 ° C.) by the injection nozzles 41 and 41a for the upper and lower silol surfaces, respectively, so as to prevent damage caused by heat that is added to the silol surface. The supply pipes 42 and 42a and the manual valves 43 and 43a are installed at the upper and lower positions so that nitrogen (N 2 ) of the following is introduced, and is generated during operation by spraying by automatic control by the automatic valve 44. Cooling is performed on the surface of the silol, which makes it possible to stabilize the operation by automatically adjusting the gap according to the thickness of the material, improving the quality of the furnace atmosphere, preventing premature roll loss, and preventing the silol overload.
이상과 같은 본 발명의 가열로 입측의 실롤콘트롤 장치에 의하면 진행되는 스트립 두께에 의한 자동간격조정이 가능하도록하여 롤 간격편차에 따른 원단위 요인을 예방하고, 작업중 발생되는 하부롤 과부하 현상을 방지하여 과부하에 따른 라인정지로 품질하락 및 생산성 저해요인을 방지하였으며, 가열로 내부에서 빠져나오는 고열원에 의해 발생되는 실롤의 잦은 밴딩 및 롤 소손으로 인해 일어나는 롤 교체등으로 손실되는 비능률 작업방법을 방지하므로써 안전사고 및 원가손실, 품질향상과 생산성 향상을 기할 수 있는 효과가 있다.According to the silol control device at the side of the heating furnace of the present invention as described above, it is possible to automatically adjust the interval by the thickness of the strip to prevent the unit factor caused by the roll gap deviation, and to prevent the lower roll overload phenomenon generated during the work load It prevented the quality deterioration and productivity deterioration factor by stopping the line, and prevented the inefficient working method lost due to the frequent banding of the rolls caused by the high heat source exiting from the inside of the furnace and the roll replacement caused by the roll burnout. It has the effect of safety accidents, cost loss, quality improvement and productivity.
