본고안은 용탕으로부터 직접 박판(strip)을 제조하는 쌍롤형 박판제조장치에 관한 것으로, 보다 상세히는 박판을 연속주조하는 경우에 박판의 일발을 용이하고 안전하게 할 수 있는 유연한 박판 안내 지지장치(Fiexible Sttip Guide)관한 것이다.The present invention relates to a twin roll type sheet manufacturing apparatus for producing strips directly from molten metal, and more particularly, a flexible sheet guide supporting apparatus (Fiexible Sttip) that can easily and safely remove the thin plates when continuous sheet casting is performed. Guide).

일반적으로 쌍롤형 박판제조장치(100)는 박판주조용로울러(110) 하부에 제1도 및 제2도에 도시한 바와같이 고정식 안내대(120)를 갖추고 있다.In general, the twin roll-type thin plate manufacturing apparatus 100 is provided with a fixed guide 120 as shown in Figure 1 and 2 below the thin plate casting roller (110).

상기 안내대(120)는 박판주조용로울러(110)로 부터 주조되는 박판(130)을 회전 로울러 테이블(140)로 안내하여 주는 기능을 갖추고 있다.The guide 120 has a function of guiding the thin plate 130 cast from the thin plate casting roller 110 to the rotary roller table 140.

그러나 박판제조시에는 일반적인 후판 연속주조 방법보다 주조속도가 매우 빠르기 때문에, 이러한 주조 속도와 인발속도를 제어하기 위해서는 안내대(120)와 인발 로울러(150) 사이에 루프(loop)부(160)를 박판에 형성시켜 작업에 임하고 있다. 보다 상세히 설명하면, 제1도에서와 같이 안내대(120)와 인발 로울러(150) 사이에 형성된 박판(130)의 루프부(160)는 주조속도와 인발속도의 차이를 완충하는 역활을 하여 안정된 작업을 수행할 수 있도록 하고, 제2도에 도시된 박판의 루프부 (160)는 박판주조용로울러(110)로부터 박판(130)이 주조됨과 동시에 형성되어 속도를 제어하도록 되며, 이때 안내대(120)는 단지 상기 박판(130)의 인발시 눈금자 역활만을 수행하도록 구성되어 있다.However, in the case of thin plate manufacturing, since the casting speed is much faster than that of a general thick plate continuous casting method, in order to control the casting speed and the drawing speed, a loop unit 160 is provided between the guide 120 and the drawing roller 150. We form on thin plate and work on work. In more detail, as shown in FIG. 1, the loop portion 160 of the thin plate 130 formed between the guide 120 and the drawing roller 150 serves to buffer the difference between the casting speed and the drawing speed. In order to perform the operation, the loop portion 160 of the thin plate shown in FIG. 2 is formed at the same time as the thin plate 130 is cast from the thin plate casting roller 110 to control the speed, at this time guide 120 ) Is only configured to perform the role of the ruler when the thin plate 130 is drawn out.

그러나, 상기 각각의 방법들은 루프부(160)를 박판에 형성시킴으로서 속도제어는 용이하지만, 상기 루프부(160)에서의 박판 무게 때문에 박판주조용 로울러 (110)의 주조면(Roll nip)(100a)근방에서 용강이 응고되면서 힘을 받게 되어 주조되는 박판(130)이 단락될 위험이 있는 것이었다.However, the respective methods are easy to control the speed by forming the loop portion 160 in the thin plate, but due to the weight of the thin plate in the loop portion 160, the roll nip (100a) of the roll casting roller 110 As the molten steel solidified in the vicinity, there was a risk that the thin plate 130 to be cast shorted.

만일, 상기와같이 박판(130)이 단락되는 경우에는 더이상 박판을 인발할 수 없게되어 연속주조 작업이 중단되거나, 주편터점(break-out)등의 설비사고를 초래하기 때문에 매우 큰 작업 위험성을 내포하고 있는 것이다.If the thin plate 130 is short-circuited as described above, the thin plate cannot be drawn out any more, and thus, continuous casting work may be interrupted or equipment accidents such as break-out may occur. I'm doing it.

본고안은 상기와 같은 종래의 문제점을 해소하기 위하여 안출된 것으로서, 박판의 단락을 방지하고, 인발을 용이하게 하며, 안전한 작업을 수행할 수 있도록 한 박판 안내지지장치를 제공함에 그 목적이 있다.The purpose of the present invention is to provide a thin plate guide support device which is devised to solve the conventional problems as described above, to prevent short circuit of the thin plate, to facilitate drawing, and to perform a safe operation.

The thin plate guide support device 1 has a predetermined length, has flexibility, and has a guide support 10 having one end portion horizontally fixed to a deflector roll 170. Detailed configuration of the guide support 10 will be described in more detail below with reference to FIG. In addition, the other end of the guide support 10, the winding device 30 for winding or unwinding the guide support 10 is located, the winding device 30 is forward, reverse rotation with an electric motor (not shown) It is comprised with the possible roller 30a. In addition, a rotary roll 40 for slidably supporting the guide support 10 is located in the middle lower portion of the guide support 10, and the rotary roll 40 is disposed between the deflector and the deflector 170. The loop part 50 of the guide support 10 is formed. In the above configuration, the rotary roll 40 is configured as one, but the present invention is not limited thereto and may include a plurality of rotary rolls 40.

제4도에 도시된 안내지지대(10)는 a)도에 도시된 바와같이 가요성을 갖춘 박판으로된 단일판 구조를 갖출수도 있고, b)도에 도시된 바와같이 다수개의 로울러 (11)가 각각 양측면에 돌기부(11a)를 갖추며, 상기 돌기부(11a)에 회전가능토록 복수개의 연결대(12)가 삽입되고, 고정캡(미도시)등으로 결합되어 일정길이의 안내지지대(10)를 구성할 수도 있다. 그리고, c)도에 도시된 바와같이 다수개의 박판 (130)이 각각 양측면에 구멍(미도시)을 형성하고 상기 구멍을 연결하는 고리(15)에 의해 가요성을 갖추도록 구성될 수도 있다.The guide support 10 shown in FIG. 4 may have a flexible single-plate structure as shown in a), and as shown in b) a plurality of rollers 11 may be provided. Each side is provided with protrusions 11a, and a plurality of connecting rods 12 are inserted into the protrusions 11a so as to be rotatable, and are coupled with a fixing cap (not shown) to form a guide support 10 having a predetermined length. It may be. And, as shown in c) a plurality of thin plates 130 may be configured to have flexibility by the ring 15 to form holes (not shown) on both sides and connect the holes, respectively.

미설명부호(120)는 종래와 같은 고정식 안내대이고, (140)는 회전로울러레이블이다.Reference numeral 120 is a fixed guide as in the prior art, 140 is a rotating roller label.

이하, 본고안의 작용 및 효과에 대하여 설명한다.The operation and effects of the present invention will be described below.

박판주조용로울러(110)로부터 주조된 박판(130)은 인발 로울러(150)에 의해 연속적으로 주조되는 바, 이때 상기 인발 로울러(150)의 전방부에서 박판의 루프부 (160)가 형성된다. 이때, 상기 박판주조용로울러(110)로부터의 주조속도가 인발 로울러(150)의 인발속도보다 크게 되어 생성되는 박판의 루프부(160)는 가요성의 안내지지대(10)의 루프부(50) 상부면에 놓여지게 된다. 작업자는 상기와 같은 상태에서 권취장치(30)를 작동시켜 안내지지대(10)를 감아주거나 풀러주어서 적절히 박판의 루프부(160)를 안내지지대(10)의 루프부(50)로서 받쳐줌으로서 박판(130)의 무게를 지탱한다. 따라서 박판주조용로울러(110)의 주조면(110a) 근방에서 박판(130)에 무리한 하중을 주지 않게되어 종래의 발생되었던 작업의 위험성이 제거되는 효과를 얻게 된다. 또한, 안내지지대(10)가 가요성을 갖추고, 권취장치(30)에 의해 적절히 루프부(50)를 형성하기 때문에 박판(130)이 주조작업중에 접히거나 손상이 방지될 수 있다. 그리고 제3도에서 점선으로 도시된 바와같이, 박판 주조작업초기나, 박판이 단락되어 재주조 작업을 시작하는 초기에는, 안내지지대(10)가 권취장치(30)에 의해 팽팽한 상태로 인장되어 경사면(10a)을 형성하기 때문에, 주조된 박판(130)의 선단부가 쉽게 상기 안내지지대(10)의 경사면(10a)을 따라서 인발 로울러(150)로 안내되는 효과를 갖출수도 있다.The thin plate 130 cast from the thin plate casting roller 110 is continuously cast by the drawing roller 150. At this time, the loop portion 160 of the thin plate is formed at the front of the drawing roller 150. At this time, the casting speed from the thin plate casting roller 110 is greater than the drawing speed of the drawing roller 150, the loop portion 160 of the thin plate is the upper surface of the roof portion 50 of the flexible guide support 10 Will be put on. In the above state, the operator operates the winding device 30 to wind or unwind the guide support 10 to appropriately support the loop portion 160 of the thin plate as the loop portion 50 of the guide support 10. Supports the weight of 130. Therefore, in the vicinity of the casting surface (110a) of the thin plate casting roller 110, the excessive force is not applied to the thin plate (130) to obtain the effect of removing the risk of the conventionally generated work. In addition, since the guide support 10 is flexible and the loop portion 50 is properly formed by the winding device 30, the thin plate 130 can be folded or damaged during the casting operation. And as shown by the dotted line in FIG. 3, at the beginning of the thin plate casting operation, or at the beginning of the thin plate is short-circuited to start the re-casting operation, the guide support 10 is tensioned by the winding device 30 to be inclined state Since the 10a is formed, the tip of the cast thin plate 130 may be easily guided to the drawing roller 150 along the inclined surface 10a of the guide support 10.

따라서, 본고안에 의하면 쌍롤형 박판제조장치에서 박판을 주조작업하는 경우, 박판의 루프부를 안내지지대가 인발 로울러 전방부에서 안전하게 받쳐주기 때문에 박판의 단락이 방지되고, 설비사고를 방지할 수 있는 실용상의 효과가 얻어지게 된다.Therefore, according to the present proposal, when the thin plate is cast in the twin roll type thin plate manufacturing apparatus, since the guide support supports the loop portion of the thin plate securely at the front of the drawing roller, the short circuit of the thin plate can be prevented and equipment accident can be prevented. The effect is obtained.
