Description

래들로 천정의 캐스팅 작업용 지그{Jig for casting for ceiling for ladle furnace} Jig for casting for ceiling for ladle furnace}

본 고안은 래들로 천정의 내면에 내화물을 캐스팅하는 래들로 천정의 캐스팅 작업용 지그에 관한 것이다. The present invention relates to a jig for casting a ceiling of a ladle for casting a refractory on the inner surface of the ladle.

일반적으로 제강공정에서 용강을 담는 용기인 래들은 그 사용용도에 따라 주조래들, 장입래들, 진공처리래들 등으로 구분할 수 있으며, 이러한 래들의 내벽에는 내화물이 축조되어 있으며, 일정기간 사용후는 내화물을 보수하기 위해 재시공한다.In general, ladles, which are containers containing molten steel in the steelmaking process, can be classified into cast ladles, charged ladles, and vacuum-treated ladles according to their use. Refractories are built on the inner walls of these ladles. Rebuild to repair the refractory.

상기 래들은 제강공정에서 취련 완료된 용융된 용강을 담아서 이송하여 정련로 또는 턴디쉬 등에 공급하는데, 래들에 전극을 설치하여 직접 정련하는 래들로가 개시되어 있다.The ladle contains molten steel that has been blown in the steelmaking process and transported to be supplied to a smelting furnace or a tundish, and the like.

이러한 래들로(10)는, 도1에 도시한 바와 같이 래들 본체(11)의 상부에 천정(12)이 설치되고, 상기 천정(12)을 관통하여 전극(13)이 설치되며, 상기 래들 본체(11)와 천정(12)은 철피(11a)(12a)의 내면에 다수층의 내화물(11b)(12b))을 캐스팅한 구조이다. 천정(12)에는 상기 래들 본체(11)의 내부로 삽입되는 삽입부(12c) 와 상기 래들 본체(11)를 덮은 링부(12d)가 형성되어 있다.As shown in FIG. 1, the ladle 10 includes a ceiling 12 disposed on an upper portion of the ladle main body 11, an electrode 13 penetrating through the ceiling 12, and the ladle main body. (11) and the ceiling (12) have a structure in which a plurality of layers of refractory materials (11b, 12b) are cast on the inner surfaces of the shells (11a) and (12a). The ceiling 12 has an insertion portion 12c inserted into the ladle body 11 and a ring portion 12d covering the ladle body 11.

종래 상기 천정(12)에 내화물(12b)을 시공하거나 재시공할 경우에는, 래들 본체(11)에서 분리시킨 천정(12)을 작업대 위에 뒤집어 놓고, 그 링부(12c)에 철근을 용접하여 고정하여, 천정(12)을 움직이지 않게 하여 캐스팅 작업을 하였다.When refractories 12b are constructed or rebuilt on the ceiling 12 in the related art, the ceiling 12 separated from the ladle body 11 is turned upside down on a work table, and steel bars are welded and fixed to the ring portion 12c. The ceiling 12 was immobilized for casting.

그런데, 이와 같이 래들로의 천정의 링부에 철근을 용접하여 천정을 고정하여 캐스팅 작업을 하는 경우에는, 천정을 옮길시에 철근을 화염으로 이동해야 하는 번거로움이 있었으며, 철근을 떼어낼 시에 손상되는 링부의 수정이 불가능하여 내화물 시공부의 품질이 저하한다는 문제점이 있었다.However, in this case, when reinforcing the ceiling by casting reinforcing bars in the ring portion of the ladle to the ceiling, there is a hassle to move the rebar to the flame when moving the ceiling, and damage when removing the rebar There was a problem in that the quality of the refractory construction part was lowered because the ring part could not be modified.

따라서, 본 고안은 상기 문제점을 해결하기 위해 이루어진 것으로서, 본 고안의 목적은 래들로 천정에 내화물을 캐스팅 작업할 시에 천정을 용이하게 고정하고 캐스팅 작업완료시 천정을 용이하게 이동할 수 있으며 천정의 내화물 시공 품질을 높이는 래들로 천정의 캐스팅 작업용 지그를 제공하는데 있다.Therefore, the present invention has been made to solve the above problems, an object of the present invention is to easily fix the ceiling when casting the refractory to the ladle ceiling and to easily move the ceiling when the casting work is completed and the refractory of the ceiling The purpose is to provide a jig for casting the ceiling of the ladle to improve the construction quality.

본 고안에 의한 래들로 천정의 캐스팅 작업용 지그는, 래들로 천정의 캐스팅 작업시에 작업대 위에 안착되는 베이스판과, 상기 베이스판의 상면에 고정되어 상기 래들로 천정의 링부 외면을 지지하는 지지수단을 구비하되, 상기 지지수단은 상기 베이스판의 상면에 용착된 베이스 브라켓과, 상기 베이스 브라켓에 결합되어 상기 링부의 외면에 밀착하여 지지하는 조정부재로 이루어진다.Jig for casting the ladle ceiling according to the present invention, the base plate seated on the workbench during the casting of the ladle ceiling and the support means fixed to the upper surface of the base plate to support the outer ring portion of the ladle ceiling The support means includes a base bracket welded to an upper surface of the base plate, and an adjustment member coupled to the base bracket to closely support the outer surface of the ring part.

상기 베이스 브라켓에는 조정부재가 나사결합되는 암나사부가 형성되고, 상기 조정부재는 상기 암나사부에 나사결합되는 볼트로 되어 있다.The base bracket is provided with a female screw portion for screwing the adjusting member, and the adjusting member is a bolt screwed to the female screw portion.

본 고안에 의한 래들로 천정의 캐스팅 작업용 지그에 의하면, 래들로 천정에 내화물을 캐스팅 작업할 시에 천정을 용이하게 고정하고, 캐스팅 작업완료시 천정을 용이하게 이동하며, 캐스팅 작업시 및 작업 완료시 천정의 위치변경을 용이하게 할 수 있으므로, 캐스팅 품질을 향상하고 작업 능률을 향상하며 링고정을 위한 용접비용 및 자재비를 절감하는 효과가 있다.According to the jig for casting work of the ladle ceiling according to the present invention, the ceiling is easily fixed when casting the refractory to the ladle ceiling, the ceiling is easily moved when the casting work is completed, at the time of casting work and completion of work Since it is possible to easily change the position of the ceiling, it has the effect of improving the casting quality, improving the work efficiency and reducing the welding cost and material cost for fixing the ring.

이하, 본 고안의 실시예에 대해 첨부도면을 참조하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도2는 본 고안의 지그(100)로 래들로 천정을 고정한 상태를 나타내며, 도3의 도2에 개시된 지지수단을 상세히 나타낸 도면이다. 도시한 바와 같이 작업대(W)에는 베이스판(110)을 설치하고, 상기 베이스판(110) 상에는 래들로의 천정(120)을 뒤집어 안치한다.Figure 2 shows a state in which the ceiling is fixed to the ladle with the jig 100 of the present invention, a view showing in detail the support means disclosed in Figure 2 of FIG. As shown, the base plate 110 is installed on the work table W, and the ceiling 120 to the ladle is placed upside down on the base plate 110.
