る溶滓傾注樋に係る。[Detailed description of the invention] The present invention relates to a slag pouring gutter, and more specifically, to prevent the slag separated from the hot metal due to the difference in specific gravity from adhering to the lining heat-resistant bricks.
Heat-resistant bricks can be effectively heated using electrically conductive heat-generating refractories, and even if this refractory is interposed in the lining heat-resistant brick layer, there will be no structural problems at all, and the refractories will not be damaged by oxidation etc. when they heat up. This invention relates to a tilting slag pouring gutter that allows the slag to be distributed into a pot, etc. without any trouble.

滓樋２を通って溶滓傾注樋３に流出され、この溶滓傾注
樋３の左右に配置された溶滓鍋４に振分けられ、その後
、溶滓鍋４は台車５とともに排出される。Generally, molten slag 1 generated in a blast furnace is usually decomposed into hot metal due to the difference in specific gravity in a skimmer, and flows out through a slag pouring gutter 2 through a slag pouring gutter 3 as shown in FIG. The slag ladle 4 is distributed to the left and right sides of the slag ladle 4, and then the slag ladle 4 is discharged together with the cart 5.

除去しているが、ある程度多く付着したときは、出銑を
待っている間に作業員が傾注樋に乗り、エアーブレーカ
ー等を用いて付着滓を除去する作業を行なっノている。In this tilting trough 3, the inside of the external shell 3a is lined with a heat-resistant lining brick 3b, but the molten slag solidifies and adheres to the heat-resistant lining brick 3b, blocking the flow of the molten slag. The slag is removed from the cast bed using a metal rod, etc., but when a certain amount of slag has adhered, a worker climbs onto the tilting trough and uses an air breaker etc. to remove the slag while waiting for tapping. It's there.
この作業は危険であるばがりがきわめて高熱の重筋作業
であり、最近では、この危険作業解消のため、バツクフ
オー（エアーブレーカー付）で鋳床から機械的に付着滓
を除去することも行なわれている。This work is not only dangerous, but also extremely hot and heavy-duty work.Recently, to eliminate this dangerous work, mechanical removal of slag from the cast bed using a backhoe (equipped with an air breaker) has been carried out. ing.
しかし、この作業はあくまで機械的な除１去作業である
ため、付着帯を細く完全に落すことが困難であり、その
操作は作業員が人力で行なう場合ほど十分に行なえない
ため時間もかかり、傾注樋の内張り耐熱レンガを傷つけ
ることもあって、その改善が求められている。However, since this work is strictly a mechanical removal work, it is difficult to completely remove the adhesive band, and the operation cannot be performed as thoroughly as when it is done manually, so it is time-consuming. There is a need to improve this problem as it can damage the heat-resistant brick lining of the tilting gutter.
本考案は上記欠点の解決を目的とし、具体的には、内張

FIG. 5 is an enlarged view of the portion shown in FIG. FIG. 2 is an explanatory diagram of an example of a diagram and a circuit using the diagram.
まず、第２図において、符号３は一般的に傾注樋を示し

熱レンガ３ｂによってライニングし、更に、略々中央部
のトラ二オン３Ｃは軸受３ｄで支承する。First, in FIG. 2, the reference numeral 3 generally indicates a tilting trough. In this tilting trough 3, the inside of the outer shell 3a is lined with a lining heat-resistant brick 3b, and the trunnion 3C approximately in the center is Supported by bearing 3d.
このトラニオン３Ｃの一端はアーム６を介して、例えば
油圧シリンダ７に連結し、油圧シリンダ７の駆動により
トラ二オン３Ｃを中心として傾動できるよう構戊する。One end of the trunnion 3C is connected to, for example, a hydraulic cylinder 7 via an arm 6, and is configured to be tilted about the trunnion 3C by driving the hydraulic cylinder 7.
次に、上記構成に係る傾注樋において、その内張り耐熱

域８により内張り耐熱レンガ３ｂを加熱し、排滓時に溶
滓が付着しないよう保護する。Next, in the tilting gutter having the above structure, a heat generating zone 8 is formed in the middle part of the lining heat-resistant brick 3b, and the heat-generating zone 8 heats the lining heat-resistant brick 3b to prevent molten slag from adhering during slag discharge. Protect.
すなわち、傾注樋３の内張り耐熱レンガ３ｂの中間部に
発熱帯域８を形或すると、この発熱帯域８の存在により
内張り耐熱レンガ３ｂは加熱されているため、排滓時に
溶滓が内張り耐熱レンガ３ｂに接触しても冷却されるこ
とがなく、凝固して付着しない。That is, when the heat-generating zone 8 is formed in the middle of the heat-resistant lining brick 3b of the tilting trough 3, the heat-resistant lining brick 3b is heated due to the presence of the heat-generating zone 8, so that when the slag is discharged, the molten slag flows into the heat-resistant lining brick 3b. Even if it comes into contact with it, it will not be cooled and will not solidify and adhere.
しかし、傾注樋は通常１０００℃の如ききわめて高温な
溶１銑を対象とし、その処理量は高炉の容量にもよるが
多大であって、発熱帯域８はその構造的要求や温度的要
