Description

압연강판 냉각수의 분사량 측정장치{Injection Volume Measuring apparatus of Cooling Water for Rolling Steel plate}Injection volume measuring device for cooling water of rolled steel sheet

본 발명은 압연강판 냉각수의 분사량 측정장치에 관한 것으로서, 더욱 상세하게는 압연강판을 냉각시키기 위하여 분사되는 냉각수의 분사량을 측정하는 압연강판 냉각수의 분사량 측정장치에 관한 것이다.The present invention relates to an injection amount measuring device for a rolled steel sheet cooling water, and more particularly, to an injection amount measuring device for a rolled steel sheet cooling water for measuring the injection amount of the cooling water injected to cool the rolled steel sheet.

일반적으로 연주기에서 생산된 슬라브를 수요자가 요구하는 두께의 강판으로 제조할 때에는 상기 슬라브를 가열한 후 다수의 압연롤이 설치된 압연기를 통과시키면서 압연하여 적정두께를 갖는 강판을 생산하고 있으며 상기 압연기의 최종단계에는 생산된 강판이 권취부에서 권취할 수 있도록 상기 강판의 표면에 냉각수를 분사시켜 냉각하는 냉각설비가 설치되어 있다.In general, when the slab produced in the machine is manufactured into a steel sheet having a thickness required by the consumer, the slab is heated and then rolled while passing through a rolling mill provided with a plurality of rolling rolls to produce a steel sheet having an appropriate thickness. In the step, a cooling facility is installed to cool the sprayed water by spraying the cooling water on the surface of the steel sheet so that the produced steel sheet is wound around the winding portion.

상기 냉각설비는 열연공정의 마지막 단계로서 생산된 강판을 냉각시키는 장치이며 사상압연의 최종단계에서 권취시 까지의 온도를 조절하는 것으로서 ROT(Run Out Table)와 함께 조합되어 개별 콘트롤이 가능하도록 복수의 냉각 그룹으로 설치되어 있으며 최종 2개의 그룹은 권취를 양호하게 하기 위하여 최종 콘트롤 시스템이 설계되어 있다.The cooling equipment is a device for cooling the steel sheet produced as the final stage of the hot rolling process and controlling the temperature from the final stage of finishing rolling to the winding, and combined with the ROT (Run Out Table) to enable individual control. It is installed as a cooling group and the final two groups have a final control system designed to achieve good winding.

상기 각각의 냉각 그룹에는 강판의 상하양면에 냉각수를 분사시키도록 상기 강판을 중심으로 상/하부에 위치되는 상/하부헤드가 각각 마련되고 그 상/하헤드에는 강판의 상/하면에 냉각수가 골고루 분사되도록 다수개의 분사노즐이 각각 마련되며 상기 각 분사노즐의 단부는 강판의 표면을 향하도록 절곡되어 있다.Each of the cooling groups is provided with upper and lower heads respectively positioned on the upper and lower sides of the steel sheet so as to spray cooling water on the upper and lower surfaces of the steel sheet, and the upper and lower heads have the cooling water evenly on the upper and lower surfaces of the steel sheet. A plurality of spray nozzles are provided to be sprayed, respectively, and ends of the spray nozzles are bent to face the surface of the steel sheet.

한편, 상기 각 냉각그룹은 냉각수탱크와 파이프로 연결되며 그 파이프 상에는 생산되는 강판에 따라서 냉각 패턴에 맞게 냉각수의 공급량을 조절하도록 밸브가 마련되어 있다.On the other hand, each cooling group is connected to the cooling water tank and the pipe, the valve is provided on the pipe to adjust the supply amount of cooling water according to the cooling pattern according to the steel sheet produced.

상기 냉각 패턴은 강판의 양면을 균일하게 냉각시키기 위한 최적의 상태를 유지하도록 다년간 연구된 결과에 의해 강판의 냉각불량(과냉, 편냉, 소냉)을 방지하도록 냉각수의 공급량 및 공급시간이 정형화 되어있다.The cooling pattern has been formulated to prevent the cooling failure (supercooling, single cooling, small cooling) of the steel sheet by the results of many years of research to maintain the optimum state for uniformly cooling both sides of the steel sheet, the supply amount of the cooling water and the supply time.

따라서 종래에는 도 1에 나타낸 바와 같이 압연된 강판(1)이 롤러테이블(2)에 안내를 받으면서 냉각설비로 이송되면 냉각수탱크(3)와 냉각헤드(4)를 연결하는 연결관(5)에 마련된 급수밸브(6)가 개방되어 상기 냉각수탱크(3)에 보관된 냉각수는 냉각헤드(4)에 마련된 다수개의 분사노즐(7)을 통하여 분사되면서 상기 강판(1)의 상/하면을 균일하게 냉각시키게 되는 것이다.Therefore, in the related art, when the rolled steel sheet 1 is transferred to a cooling facility while being guided by the roller table 2, as shown in FIG. 1, a connection pipe 5 connecting the cooling water tank 3 and the cooling head 4 is provided. The supplied water valve 6 is opened and the cooling water stored in the cooling water tank 3 is sprayed through the plurality of injection nozzles 7 provided in the cooling head 4 to uniformly cover the upper and lower surfaces of the steel plate 1. It is cooled down.

이러한 냉각설비는 장기간 사용으로 인하여 연결관(5) 및 밸브(6) 그리고 분사노즐(7)에 이물질이 침적되거나 냉각수의 공급량 부족으로 각 분사노즐을 통하여 분사되는 냉각수가 불균등하게 분배되면 상기 강판(1)의 냉각이 불량(과냉, 편냉, 소냉)하게 되므로 편석 또는 재질편차 등으로 인하여 불량제품이 생산되는 것이다.This cooling system is characterized in that if the cooling water injected through each injection nozzle is unevenly distributed in the connection pipe 5, the valve 6, and the injection nozzle 7 due to long-term use, the steel sheet ( Since the cooling of 1) is poor (supercooled, single-cooled, small-cooled), defective products are produced due to segregation or material deviation.

이를 방지하기 위하여 분사노즐(7)을 통하여 분사되는 냉각수의 분사량을 수시로 측정하고 있으며 이때에는 설비를 정지시킨 후 냉각수탱크(3)와 냉각헤드(4)의 사이에 설치된 급수밸브(6)등 각 부품의 조절을 작업자가 수작업으로 조절하면서 수행하므로 작업이 불편하였고 작업시간 동안에는 설비를 정지시킴에 따른 생산성이 저하되는 등의 문제점이 있었다.In order to prevent this, the amount of injection of the coolant injected through the injection nozzle 7 is often measured. In this case, the water supply valve 6 installed between the coolant tank 3 and the cooling head 4 after stopping the facility Since the operator performs the adjustment of parts by manual adjustment, the work is inconvenient, and there is a problem that productivity is reduced due to stopping the equipment during the working time.

본 발명은 상기와 같은 문제점을 해결하기 위하여 발명한 것으로서, 그 목적은 강판을 냉각시키기 위하여 분사노즐로 분사되는 냉각수의 분사량을 자동으로 측정하여 냉각불량으로 인한 강판의 재질편차, 편석등을 미연에 방지할 수 있는 압연강판 냉각수의 분사량 측정장치를 제공함에 있다.The present invention has been invented to solve the above problems, the purpose is to automatically measure the injection amount of the cooling water injected into the injection nozzle in order to cool the steel sheet, the material deviation, segregation, etc. of the steel sheet due to poor cooling An object of the present invention is to provide an injection amount measuring apparatus for a cold rolled steel sheet which can be prevented.

먼저 측정하고자하는 냉각그룹으로 대차(10)가 이동되도록 상기 대차(10)에 마련된 모터(11)를 구동시키면 그 모터(11)에서 발생되는 회전력은 체인(13)을 통하여 전달되어 대차(10)의 저면에 마련된 바퀴(12)를 회전시키게 되며 상기 대차(10)가 원하는 위치로 이동되면 모터(11)를 정시킨다.First, when the motor 11 provided in the bogie 10 is moved to move the bogie 10 to the cooling group to be measured, the rotational force generated by the motor 11 is transmitted through the chain 13 to the bogie 10. Rotate the wheel 12 provided on the bottom of the motor 10 is determined when the trolley 10 is moved to a desired position.

그리고 승강수단(20)에 마련된 제1실린더(25)를 작동시키면 상기 대차(10)의 상부에 마련된 승강판(24)이 상승하게 되며 이때 대차(10)와 승강판(24)의 사이에 마련된 링크(22)의 일측 즉, 승강판(24)에 결합된 상부측이 상기 승강판(24)과 함께 상승하게 되어 상기 링크(22)는 중앙에 마련된 힌지(21)를 중심으로 작동되면서 타측 상/하부에 설치된 안내롤(23)은 승강판(24)과 대차(10)에 접촉된 상태로 회전하면서 이동되므로 상승하는 승강판(24)의 저면을 지지하게 되는 것이다.And when operating the first cylinder 25 provided in the elevating means 20, the elevating plate 24 provided on the upper portion of the trolley 10 is raised, at this time provided between the trolley 10 and the elevating plate 24 One side of the link 22, that is, the upper side coupled to the elevating plate 24 is raised together with the elevating plate 24, so that the link 22 is operated about the hinge 21 provided at the center and the other side thereof. The guide roll 23 provided at the lower portion is moved while rotating while being in contact with the lifting plate 24 and the trolley 10, so that the bottom surface of the rising lifting plate 24 is supported.

상기와 같이 승강판(24)이 상승되면 제1실린더(25)가 정지함과 동시에 좌/우이동수단(30)에 마련된 제2실린더(33)가 작동되어 좌/우이동판(32)의 위치를 이동시키게 된다. 이때 상기 좌/우이동판(32)은 승강판(24)의 상면에 마련된 레일(31)에 안내를 받으면서 원활하게 이동되어 그 상부에 마련된 측정수단(40)은 냉각헤드(4)에 마련된 분사노즐(7) 측으로 이동된다.When the lifting plate 24 is raised as described above, the first cylinder 25 is stopped and the second cylinder 33 provided in the left / right moving means 30 is operated to adjust the position of the left / right moving plate 32. Will be moved. At this time, the left / right moving plate 32 is smoothly moved while being guided by the rail 31 provided on the upper surface of the elevating plate 24, and the measuring means 40 provided at the upper portion of the injection nozzle is provided at the cooling head 4. (7) is moved to the side.

이러한 상태에서 측정수단(40)에 마련된 복수개의 제3실린더(41)를 동시에 작동시키면 지지판(42)의 위치가 이동하게 되며 상기 제3실린더(41)는 개별적으로작동시켜도 무방하다. 상기 지지판(42)의 상부에 마련된 컵(44)은 분사노즐(7)의 직하방에 위치되므로 상기 분사노즐(7)을 통하여 분사되는 냉각수는 컵(44)에 담겨지게 되는 것이다.In this state, when the plurality of third cylinders 41 provided in the measuring means 40 are operated at the same time, the position of the support plate 42 is moved, and the third cylinders 41 may be operated individually. Since the cup 44 provided on the upper portion of the support plate 42 is located directly below the injection nozzle 7, the cooling water injected through the injection nozzle 7 is contained in the cup 44.

일정시간 후 상기 제3실린더(41)를 역방향으로 작동시키면 냉각수가 담겨진 컵(44)은 초기상태로 복원되며 이때 그 컵(44)의 하부에 마련된 로드셀(43)은 컵(44)의 무게에 따라서 컵(44)에 담겨진 냉각수의 양을 측정하고 그 측정값을 기준치 비교하며 비교결과 냉각수의 양이 적을 경우에는 연결관(5)에 마련된 급수밸브(6)를 개방시키고 냉각수의 양이 많을 경우에는 연결관(5)에 마련된 급수밸브(6)를 폐쇄시키면서 냉각수의 분사량을 조절하게 되는 것이다.After a certain time, if the third cylinder 41 is operated in the reverse direction, the cup 44 containing the coolant is restored to an initial state, and the load cell 43 provided at the lower portion of the cup 44 has the weight of the cup 44.

In order to control the injection amount of the cooling water while closing the water supply valve 6 provided in the connecting pipe (5).

상기와 같이 냉각수의 분사량을 측정하여 분사량의 조절이 완료되면 배수밸브(45)를 개방시켜 컵(44)에 담겨진 냉각수를 배수시키고 제2실린더(33)를 역방향으로 구동시켜 냉각헤드(4)의 하부로 이동된 좌/우이동판(32)을 초기상태 즉, 승강판(24)의 직상부로 이동시킨다.When the injection amount of the cooling water is measured as described above, when the adjustment of the injection amount is completed, the drain valve 45 is opened to drain the cooling water contained in the cup 44, and the second cylinder 33 is driven in the reverse direction of the cooling head 4. The left / right moving plate 32 moved downward is moved to an initial state, that is, directly above the lifting plate 24.

그리고 승강판(24)에 마련된 제1실린더(25)를 역방향으로 작동시키면 상승되어 있던 승강판(24)은 하강하게 되며 상기 승강판(24)과 대차(10)의 사이에 마련된 링크(22)는 상기 승강판(24)의 자중에 의해서 눌려지게 되므로 그 일측 상하부에 마련된 안내롤(23)이 회전되면서 중앙에 마련된 힌지(21)를 중심으로 작동되어 승강판(24)이 원활하게 하강되도록 안내하게 되는 것이다.When the first cylinder 25 provided in the elevating plate 24 is operated in the reverse direction, the elevated elevating plate 24 is lowered, and the link 22 provided between the elevating plate 24 and the trolley 10 is provided. Since it is pressed by the weight of the elevating plate 24, the guide roll 23 provided on the upper and lower sides of the elevating plate 24 is rotated to operate around the hinge 21 provided in the center to guide the elevating plate 24 to be smoothly lowered. Will be done.

이와 같이 승강판(24)이 하강되면 모터(11)를 구동시켜 대차(10)를 원하는 위치로 이동시킨 후 또다른 냉각헤드로 분사되는 냉각수의 분사량을 측정하게 되며냉각설비에 마련된 다수개의 냉각헤드로 분사되는 냉각수의 분사량 측정이 완료되면 상기 모터(11)를 역방향으로 구동시켜 대차(10)를 초기상태로 복원시키게 되는 것이다.When the lifting plate 24 is lowered as described above, the motor 11 is driven to move the bogie 10 to a desired position, and then the amount of cooling water injected into another cooling head is measured. When the injection amount of the cooling water is injected to the completion of the driving of the motor 11 in the reverse direction to restore the cart 10 to the initial state.

이상과 같은 본 발명은 모터의 구동으로 이동되는 대차의 상부에 승강수단과 좌/우이동수단에 의해서 위치이동되는 측정수단을 마련하여 그 측정수단으로 냉각헤드에서 분사되는 냉각수의 분사량을 간편하게 측정하게 됨과 함께 설비의 운전중에도 냉각수의 분사량을 간편하게 측정하여 그 측정된 결과값에 따라서 실시간으로 냉각수의 분사량을 조절하게 되므로 냉각불량으로 인한 강판의 재질편차 및 편석을 미연에 방지할 수 있는 특유의 효과가 있다.The present invention as described above provides a measuring means that is moved by the lifting means and the left / right moving means on the upper portion of the trolley moved by the drive of the motor to easily measure the injection amount of the coolant injected from the cooling head with the measuring means and In addition, it is possible to easily measure the spraying amount of the coolant during the operation of the facility and to adjust the spraying amount of the coolant in real time according to the measured result, which has a unique effect of preventing material deviation and segregation of the steel sheet due to the cooling failure. .
