Description

내화연와{A FIRE BRICK}Refractory flame {A FIRE BRICK}

본 고안은 각종 로의 내부에 축조되는 내화연와에 관한 것으로, 특히 철강,시멘트, 유리 석유화학등 각종산업에 사용되는 가열로, 소성로, 열처리로, 용융금속저장 및 운반로 등의 내화연와를 축조하는 모든 로체에 사용하여 연와 간이 음부의 이완을 방지함으로써 로체의 수명을 연장시킬수 있도록 한 것이다.The present invention relates to refractory wires that are built inside various furnaces. In particular, the present invention relates to the construction of refractory wires such as heating furnaces, firing furnaces, heat treatment furnaces, molten metal storage and transportation furnaces, which are used in various industries such as steel, cement, and glass petrochemicals. It is used for all furnaces to prolong the life of the furnace by preventing the relaxation of soft and soft joints.

일반적으로 각종 산업에 사용되는 로체(10)의 내화연와 축조시는 도 1과 같이 연와 표면에 몰탈을 바르고 그위에 연와를 쌓아가는 조적법에 의해 주로 축조되고 있으며, 일부는 행거 금물을 이용하여 연와를 결속시키는 방법이 사용되고 있으나 행거 금물 사용방법은 연와 축조작업이 까다롭고 가공부위가 많아지며 정밀한 시공이 어렵고 불량율이 많아 용강을 수강하는 로설비에는 거의 사용하지 않는 방법이며 현재는 조적법에 의해서 주로 작업이 이루어지고 있다.In general, fire retardant smoke and building time of the Roche 10 used in various industries are mainly built by the masonry method of applying mortar on the surface of the kite and stacking it on the surface of the furnace body 10, and some of them are made by using the hanger forbidden. The method of binding hanger is used, but the method of using hanger forbidden is difficult to use in the furnace equipment to take molten steel because it is difficult to make lead and construction work, and there are many machining parts, and it is difficult to precise construction and high defect rate. Work is being done.

그러나 고온 영역에서 열팽창 및 수축의 진폭이 큰 재질의 연와를 사용하는 로체, 사용중 진동이 많은 로설비와 조업을 위해 로자체가 운반되는 로설비는 조업중 기계적 충격 및 내화물의 팽창수축 반복으로 연와간 이음매를 형성하고 있는 몰타르가 이탈되어 도 2a와 같이 연와의 열팽창 및 수축으로 인해 연와간 필요 이상의 갭이 발생되어 이부위로 도 2b와 같이 조업중 용강(13)침투로 쇳물이 새어나오는 대형 설비사고의 원인이 되고 있다.However, in the high temperature region, the furnace body using the lead of material with high amplitude of thermal expansion and contraction, the furnace equipment with high vibration in use, and the furnace equipment that is transported for operation, the joints between the joints due to repeated mechanical shock and refractory expansion and contraction of the refractory. As a result of large-scale equipment accidents in which molten water leaks due to penetration of molten steel (13) during operation as shown in FIG. 2B due to thermal expansion and contraction of the lead as shown in FIG. It is becoming.

또 도 2c와 같이 연와간 공간 발생으로 지지력이 상실되어 경동되는 로 설비에 있어서 영구 사용을 목적으로 하는 내측 연와(11)가 내장 내화물(12) 해체후 배출하기 위한 로체(10) 경동시 내장내화물(12)과 동반 탈락되어 상당부분의 원가 손실을 초래하고 있는 실정이다.In addition, as shown in FIG. 2C, in the furnace equipment in which the support force is lost due to the generation of spaces between the edges, the inner edge 11 for the purpose of permanent use is internally refractories for discharging after the dismantling of the internal refractories 12. Along with (12), it was eliminated and caused a significant loss of cost.

본 고안은 상기와 같은 제반문제점을 감안하여 이를 해소하고자 고안한 것으로, 현재 조적법에 의해 로체의 내화연와 축조후 사용중 발생되는 연와 이음부 연와의 열팽창에 의한 밀림 및 돌출에서 유발하는 설비사고 방지 및 연와의 지지력 상실에 의한 경도시 내측연와의 탈락방지로 원가절감을 기하고자 하는데 그 목적이 있다.The present invention was devised to solve this problem in consideration of the above-mentioned problems, and prevents equipment accidents caused by rolling and protrusion caused by thermal expansion between flame retardant smoke and joint smoke generated during use after building construction by the masonry method. The purpose is to reduce the cost by preventing the fall of the inner edge when hardness due to loss of bearing capacity of the edge.

이와같은 목적을 갖는 본 고안은 내화재로된 연와중앙부에 소정의 크기를 갖는 관통공을 형성시키고 이에 용접부재를 삽입설치하였고, 상기 용접모재의 선단부분은 로의철피와 용접될 수 있도록 접합부를 형성하여서 된 것이다.The present invention having such a purpose is to form a through hole having a predetermined size in the middle portion of the reed and made of refractory material, and the welding member is inserted and installed therein, and the front end portion of the welding base material forms a joint so as to be welded with the steel bar of the furnace. It is.

본 고안의 내화연와(20)는 중앙부분에 소정의 크기로 관통공(21)을 형성시키고, 이에 용접모재(30)를 삽입설치하며, 상기 용접모재(30)의 선단부는 로(10)의 철피와 용접될수 있도록 소정의 너비를 갖는 접합부(31)를 형성하여서 된 것이다.The fire retardant foil 20 of the present invention forms a through hole 21 at a predetermined size in the center portion, and inserts the welding base material 30 therein, and the tip of the welding base material 30 is formed of the furnace 10. It is to form a joint 31 having a predetermined width so as to be welded with the iron bar.

이와같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

본 고안의 내화연와(20)는 도 3 및 도 4와 도 5에서 도시된 바와같이 용접모재(30)는 관형으로 되어 있어이 관통공(32)으로 용접모재(30)를 관통하며 용접봉(도면미도시)을 투입하여 로(10)의 철피와 용접모재(30)의 접합부(31)를 용접하여 접합시킨다.As shown in FIGS. 3 and 4 and 5, the fire-resistant lead 20 of the present invention has a welding base material 30 that is tubular, penetrating the welding base material 30 through the through hole 32, and a welding rod (not shown in the drawing). (C) is used to weld the joints 31 of the steel bar of the furnace 10 and the welding base material 30 to be joined.

단 상기 용접모재(30)의 재질은 SS41, SUS304, SUS310등의 용접이 쉬운 재질을 사용한다.However, the material of the welding base material 30 uses a material that is easy to weld, such as SS41, SUS304, SUS310.

본 고안의 내와연와(20) 시공방법은 조적으로 축조하는 내화연와와 일반적으로 사용하는 내화연와를 같이 사용하게 되는데, 이는 도5에서 도시된 바와같이 본 고안의 내화연와(20) 사이사이에 일반적으로 사용되는 내화연와(11)를 2개나 3개정도 부착시는 순서로 계속해서 축조한다.The method of construction of the inner and outer edges of the present invention is to be used together with the fire retardant and the generally used fire retardant, which is between the fire retardant and the fire retardant of the present invention, as shown in FIG. Continue to build the order of attaching two or three fire retardants 11 which are generally used.

이와같이하면 일반적으로 사용되는 내화연와(11)나 본 고안의 내화연와(20)가 사용도중 열팽창이 발생해도 상기 본 고안의 내화연와(20)가 용접 접합되어 있기 때문에 열팽창에 의한 밀림이 발생하지 않아 몰타르가 이탈되지 않게 되어 내화연와(11)의 탈락을 방지하여준다.In this way, even if the fire reed 11 and the fire reed 20 used in the present invention undergo thermal expansion during use, the fire retardant wire 20 according to the present invention is welded and joined, so that there is no sliding due to thermal expansion. The mortar is prevented from falling off prevents the falling of the refractory lead 11.

한편 상기 본 고안의 내화연와(20)에 형성된 관통공(32) 및 용접모재(30)의 내부는 용접모재(30)의 접합부(31)를 로(10)의 철피에 용접완료한후 내화재(33)로 충진시켜준다.On the other hand, the interior of the through-hole 32 and the welded base material 30 formed in the refractory lead 20 of the present invention is welded to the steel bar of the furnace base 10 after the joint 31 of the welded base material 30, the fireproof material ( Fill with 33).

이상과 같은 본 고안은 조적으로 축조되는 연와간 일정 부위에 용접에 의해 철피면에 연와를 용접결속 시킨으로써, 본 고안의 내화연와 자체는 물론, 주위연와와의 아주 견고한 지지력을 제공하여 로체 내화물 시공을 견고하게 하고, 연와간 갭 발생요인을 제거함으로써, 조적에만 의존한 축조작업시의 문제점인 연와간 이음부의 몰탈이탈에 의한 용강침투등의 설비사고를 방지시키며, 경동되는 로설비의 내측연와 가 경동시 탈락되는 것을 방지시켜 설비사고 방지 및 내화물 탈락에 의한 원가의 손실을 억제시키고, 또한 용접모재를 내장한 내화연와는 사용범위가 넓어 철강산업, 비금속산업, 석유화학 산업의 각종 로설비에 다양하게 이용이 가능하기 때문에 이의 상품화 효과가 있다.The present invention as described above by welding the joints to the iron skin surface by welding to a certain portion between the erected masonry, the fire retardant construction by providing a very solid support of the fire retardant and itself as well as the surrounding lead of the present design It is possible to prevent the accidents such as molten steel penetration due to the mortar of the joint between the joints, which is a problem in the construction work that depends only on the masonry, by removing the gap generation factors between the edges and the edges of the furnace equipment. It prevents dropping during Kyungdong to prevent equipment accidents and to prevent cost loss due to dropping of refractory. Also, it is widely used in various furnace facilities in the steel industry, non-metal industry, and petrochemical industry because its use range is wider than the refractory lead with built-in welding base material. Because it can be used, it has a commercialization effect.
