た。<Problems to be solved by the invention> By the way, it is necessary to replace the sleeve for the tap hole in the bottom of the furnace every predetermined charge. Traditionally, this sleeve replacement was done from the bottom of the furnace, but
The space below the furnace was narrow and workability was poor.
〈問題点を解決するための手段〉
本考案は上記したスリーブ交換時のスリーブ外
しを容易に行える電気炉を提供することを目的と
するもので、炉体出鋼部の上側のスペースを利用
して、ここにスリーブ外し治具とその駆動装置と

る。<Means for solving the problems> The purpose of the present invention is to provide an electric furnace in which the sleeve can be easily removed when replacing the sleeve. The basic feature is that a sleeve removal jig and its driving device are installed here.
スリーブ外し治具は、出鋼部の上側で出鋼孔の
真上に位置させ、上下動可能に設置する。この治
具を駆動装置により上下動させ、出鋼孔のスリー
ブを上から押して炉底へと押し出して外す。 The sleeve removal jig is located above the tapping section, directly above the tapping hole, and is installed so that it can move up and down. This jig is moved up and down by a drive device, and the sleeve of the tapping hole is pushed from above to the bottom of the furnace and removed.
なお出鋼部は通常水冷ボツクスで覆われている
から、この水冷ボツクスの出鋼孔の真上の位置に
開口を形成しておく。 Note that since the tapping section is usually covered with a water-cooled box, an opening is formed in the water-cooled box at a position directly above the tapping hole.
〈実施例〉 次に実施例を図面に基づいて説明する。<Example> Next, embodiments will be described based on the drawings.
第１図は正断面図、第２図は平面図である。図

設けられている。 FIG. 1 is a front sectional view, and FIG. 2 is a plan view. In the figure, X is the furnace body, which has a tapping portion 50 that projects in the radial direction. The tapping section 50 has a slightly shallower bottom than the main body, and a tapping hole 51 is formed at the bottom. A sleeve 52 made of firebrick is formed around the tapping hole 51, and is fixed at the bottom with a fixture 53. Also, the tapping hole 51
A swing type tapping hole opening/closing lid 54 is provided near the bottom of the tap hole.
出鋼部５０の上面は覆蓋５５により覆われてい
る。この覆蓋５５は水冷ボツクスとなつている。 The upper surface of the tapping section 50 is covered with a cover 55. This cover 55 serves as a water-cooled box.
出鋼部５０の上側のスペースに、スリーブ外し

位置の覆蓋５５には治具１が出入りするための開
口５が形成されている。 A sleeve removal jig 1 and its driving device 2 are installed in a space above the tapping section 50. The jig 1 is located directly above the tapping hole 51 and is suspended by a drive device 2 so as to be movable up and down. An opening 5 through which the jig 1 enters and exits is formed in the cover 55 located directly below the jig 1.
駆動装置２はこの実施例では油圧シリンダを用
いており、ブラケツト３を介して炉殻５６に装着
