がある。炉底電極は、高温下で使用されるため、
その冷却や熱膨張対策が必要である。 Although DC electric furnaces have advantages such as reduction in electrode consumption, reduction in skin effect, voltage and current fluctuations, and reduction in noise, they also have the problem of requiring a furnace bottom electrode. Hearth electrodes are used at high temperatures, so
Cooling and measures against thermal expansion are necessary.
〈考案の概要〉

ある。<Summary of the invention> The purpose of the invention is to provide a furnace bottom electrode structure for use in such a DC electric furnace, which includes an electrode, a bracket that contacts the lower end of the electrode, cools the electrode, and supports it. , and a spring for supporting the bracket.
即ち、ブラケツトにより電極を冷却すると共に
バネにより熱膨張、収縮を吸収しようとするもの
である。 That is, the bracket is used to cool the electrode, and the spring is used to absorb thermal expansion and contraction.
〈考案の実施例〉
以下本考案の実施例を図面に基づいて説明す

ーブレンガ３が敷設されている。 FIG. 1 is a front sectional view thereof, and FIG. 2 is a plan view thereof. In the figure, A is the hearth bottom and B is the iron shell. The electrode 1 penetrates from the iron shell B to the furnace bottom A, and its head surface is exposed into the furnace. Although a single electrode 1 or a predetermined number of electrodes 1 may be installed, in this embodiment, four electrodes are provided. Sleeve bricks 3 are laid around the electrodes with monolithic refractories 2 interposed therebetween.
電極１は全体が鋼から成り、鉄皮Ｂから突出し
た下端部がテーパ状のテーパ部１０を構成してい

凹部を有する水冷ジヤケツト４により支持されて
いる。この水冷ジヤケツト４は中空構造のCu製
となつており、給水口４０と排水口４１を備えた
水冷構造となつている。 The electrode 1 is entirely made of steel, and the lower end protruding from the iron shell B constitutes a tapered portion 10. The tapered portion 10 is supported by a water cooling jacket 4 having a concave portion corresponding to the taper. This water cooling jacket 4 has a hollow structure made of Cu, and has a water cooling structure including a water supply port 40 and a drain port 41.
水冷ジヤケツト４はまた鉄皮Ｂに固着されたブ
ラケツト５にバネ６を介して支持されている。 The water cooling jacket 4 is also supported by a bracket 5 fixed to the iron shell B via a spring 6.
７はリード線であり、ブラケツト５の側部から
導出されている。 A lead wire 7 is led out from the side of the bracket 5.
以上の構成において、電極１はそのテーパ部１
０において水冷ジヤケツト４により冷却される。
この際テーパ部１０となつているため、電極１の
自重により密着性が高く、また接触面積が大きく
なるから冷却効率が高くなる。 In the above configuration, the electrode 1 has a tapered portion 1
0, it is cooled by the water cooling jacket 4.
At this time, since the tapered portion 10 is formed, the adhesion is high due to the weight of the electrode 1, and since the contact area is increased, the cooling efficiency is increased.
また熱による電極１の膨張、収縮はバネ６によ
り吸収され不具合を生じることがない。 Further, expansion and contraction of the electrode 1 due to heat is absorbed by the spring 6, and no trouble occurs.
〈考案の効果〉
