Description

전기로 로상의 내화물 시공용 지그{A jig for building unshaped refractory in electric furnace}Jig for building unshaped refractory in electric furnace

본 고안은 전기로 로상의 내화물 시공용 지그에 관한 것으로, 특히 전기로 로상에 배치되는 내화물을 다질 수 있도록 구조가 개선된 전기로 로상의 내화물 시공용 지그에 관한 것이다.The present invention relates to a refractory construction jig on an electric furnace, and more particularly, to a refractory construction jig on an electric furnace having an improved structure to compact refractory disposed on the electric furnace.

일반적으로 금속용융 아크전기로 로상은 염기성 부정형 내화물로 되어 있고, 금속의 용해작업중에는 흑연전극에 의한 아크방전과 산소취련에 의하여 단시간에 고온으로 승온이 되고, 출강후에는 로상이 급격한 냉각을 받는 등, 매우 가혹한 조업조건에서 사용되므로 고내식성의 염기성 래밍재가 사용되고 있다.In general, the furnace is made of basic amorphous refractory, and the metal phase is heated to high temperature in a short time by arc discharge and oxygen smelting by graphite electrode, and the furnace is rapidly cooled after tapping. As a result, it is used in very harsh operating conditions, and therefore a high corrosion resistance basic ramming material is used.

전기로 로상 건식래밍재는 주로 마그네시아를 바탕으로 하고 있으나 마그네시아는 고온에서의 내침식성은 우수하지만, 용융금속 및 슬랙과 반응시 침윤이 되기 쉽고, 급열, 급냉시에는 수축, 팽창이 커서 사용중에 로상에 균열이 발생하여 용강이 침투하기 쉬워 용강유출의 위험 또한 크다. Furnace Furnace Dry ramming material is mainly based on magnesia, but magnesia has excellent corrosion resistance at high temperature, but is easily infiltrated when reacted with molten metal and slack, and shrinks and expands during rapid quenching and quenching, so it It is easy to penetrate molten steel due to cracks, and the risk of leakage of molten steel is also great.

따라서, 전기로 로상용 래밍재로서는 고온에서 내침식성 및 내침윤성이 우수하면서도 용적안정성이 좋은 래밍재의 사용이 절실히 요구되고 있다.Therefore, the use of a ramming material having good volume stability and excellent corrosion resistance and infiltration resistance at high temperatures is urgently needed as an electric furnace furnace ramming material.

그런데, 기존의 전기로 로상 내화물 시공시 내화물이 마그네시아 클링커와 간수를 혼합하여 습식 상태에서 시공하고 있으므로, 시공후 강도가 부족하여 로상 내화물이 취약한 문제점이 있다.However, since the refractory is mixed in a wet state when magnesia clinker is mixed with the brine during the construction of the existing furnace refractories, there is a problem that the refractory refractory is weak due to lack of strength after construction.

Supporting jig body 110, the weight body 120 is disposed in the space portion of the jig body 110 and has its own weight, seated on the upper portion of the weight body 120, the end is integrally combined with the inner peripheral surface of the extension It is composed of a frame 130 and a vibration generating unit 200 disposed on an upper portion of the support frame 130 to impart vibrations when external power is applied.

더 상세히 설명하면, 지그 본체(110)는 공간부가 형성되도록 원형 형태의 바닥면과 바닥면의 테두리로부터 연장되는 연장부로 구성된다.In more detail, the jig body 110 is composed of a circular bottom surface and an extension portion extending from the edge of the bottom surface to form a space portion.

중량체(120)는 자체 중량을 갖는 콘크리트 재질을 채용할 수 있으나, 굳이 이에 한정하지는 아니한다.The weight body 120 may employ a concrete material having its own weight, but is not limited thereto.

중량체(120)는 지그 본체(110)와 일체화되도록 양생하거나, 지지프레임(130)에 의해 이동이 구속되도록 배치되어도 무방하다.The weight body 120 may be disposed so as to be integrated with the jig main body 110 or to be restricted by movement by the support frame 130.

지지프레임(130)은 스틸소재로 된 것이며, 단부가 지그 본체(110)의 내주면과 용접으로 일체화된 구조를 갖는다.The support frame 130 is made of a steel material, and has an end portion of which is integrated with the inner circumferential surface of the jig main body 110 by welding.

또 지지프레임(130)은 평면에서 볼 때 "+"자 형태로 구성되며 중간에 진동발생부(200)가 안착되도록 배치된다.In addition, the support frame 130 is configured in the form of a "+" when viewed in plan and is disposed so that the vibration generating unit 200 is seated in the middle.

그리고, 지지프레임(130)은 각 단부의 상부에 크레인의 와이어로프(R)를 걸 수 있도록 인양용 고리(132)가 배치된다.And, the support frame 130 is disposed in the lifting ring 132 so as to hang the wire rope (R) of the crane on the top of each end.

진동발생부(200)는 외부 전원이 인가됨에 따라 자체 진동을 발생시키는 진동모터를 채용한다.The vibration generator 200 employs a vibration motor that generates its own vibration as an external power source is applied.

진동모터는 외부 전원이 인가되도록 외부 동력원과 전선으로 배선 연결되어 있다.Vibration motor is wired by external power source and wire so that external power is applied.

이러한 구성을 갖는 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention having such a configuration as follows.

본 고안에 따른 전기로 로상의 내화물 시공용 지그(100)는, 지그 본체(110)의 바닥면이 전기로(10) 로상의 내화물(20) 상부 표면과 접촉되도록 크레인과 와이어 로프(R)를 이용하여 지그 본체(110)를 전기로(10)의 로 내부로 배치시킨 후에, 전기로(10) 로상에 충진되는 내화물(20)을 다지는 기능을 수행한다.The refractory construction jig 100 of the furnace according to the present invention, the crane and the wire rope (R) so that the bottom surface of the jig main body 110 is in contact with the upper surface of the refractory 20 on the furnace 10. After the jig main body 110 is disposed inside the furnace of the furnace 10, the refractory 20 filled in the furnace 10 is compacted.

이때, 전기로(10) 로상에 충진된 내화물(20)은 마그네시아-클링커가 간수와 혼합되어 습식 상태를 유지하게 되므로, 중량을 갖는 본 고안의 지그(100)가 진동발생부(200)로부터 발생되는 진동력을 매개로 내화물(20)의 상부 표면을 다지는 기능을 수행한다.At this time, since the refractory 20 filled in the furnace 10 is maintained in a wet state because the magnesia-clinker is mixed with the brine, the jig 100 having the weight is generated from the vibration generator 200. It performs a function of compacting the upper surface of the refractory 20 through the vibration force.

즉, 지그 본체(110)상에 배치된 진동발생부(200)측에 외부 전원이 인가됨에 따라, 진동발생부(200)로부터 발생된 진동력이 지그 본체(110)를 통해 내화물(20)측에 전달되어 내화물(20)을 다지는 기능을 수행하게 된다. That is, as external power is applied to the vibration generating unit 200 disposed on the jig main body 110, the vibration force generated from the vibration generating unit 200 passes through the jig main body 110 to the refractory 20 side. It is delivered to the refractory 20 to perform the function.

내화물(20)측에 진동력이 전달되는 과정은 진동발생부(200)로부터 발생된 진동력이 지지프레임(130)을 거쳐 중량체(120) 및 지그 본체(110)에 전달되고, 지그 본체(110)의 바닥면과 접촉된 내화물(20)로 전달되는 과정을 갖는다.In the process of transmitting the vibration force to the refractory 20 side, the vibration force generated from the vibration generating unit 200 is transmitted to the weight body 120 and the jig main body 110 through the support frame 130, the jig main body ( The process is delivered to the refractory 20 in contact with the bottom surface of 110.

이때, 전기로(10) 로상 내화물(20)의 표면 면적보다 지그 본체(110)의 접촉 면적이 적기 때문에 크레인을 이용하여 지그 본체(110)를 이동시키거나, 작업자가 전기로(10) 로상에서 와이어 로프(R)를 파지한 상태로 원하는 위치로 이동시키면서 다짐 작업을 수행한다.At this time, since the contact area of the jig main body 110 is smaller than the surface area of the furnace refractory 20 on the electric furnace 10, the jig main body 110 is moved using a crane, or an operator moves on the electric furnace 10 furnace. The compacting operation is performed while moving to a desired position while holding the wire rope (R).

따라서, 본 고안의 지그는 습식 상태의 내화물(20)을 시공하는 과정에서 균일한 압력으로 다짐으로써, 시공이 완료된 후에 내화물(20)의 강도를 향상시킬 수 있는 이점을 갖는다.Therefore, the jig according to the present invention has the advantage of being able to improve the strength of the refractory 20 after the construction is completed by compacting at a uniform pressure in the process of constructing the wet refractory 20.
