Description
【０００１】
【発明の属する技術分野】
本願発明は、転炉炉下で溶鉄等を運搬する台車を有した製鋼設備に関するものである。
【０００２】
【従来の技術】
最近、溶銑予備処理を転炉で行うことが広まりつつある。中でも１基の転炉で脱りん処理及び脱炭処理とを行う方式がある。その際には、転炉で精錬した溶鉄を一旦専用鍋に払い出し、転炉炉内に残留したスラグを排出し、その後、前記一旦専用鍋に払い出した溶鉄をもう１度同じ転炉に再装入する専用鍋（以下、再装入鍋と称す）を保有する。従って、従来の転炉では、炉下に排出スラグを受ける排滓鍋、及び精錬後の溶鋼を受ける受鋼鍋と夫々の鍋を運搬する台車が２台あった。
【０００３】
更に、溶銑予備処理を転炉で行う場合は、前記再装入鍋を運搬する（以下再装入台車と称す）を加え、３台の台車が炉下に配備される。そして再装入台車は、排滓鍋台車と受鋼鍋台車との間に位置する。従って、再装入台車の動力源を供給するケーブルは、排滓台車あるいは、受鋼台車側どちらからか引き込むことになるが、例えば、排滓台車側から引き込んだ場合、図１のようになる。従来、転炉からスラグを排滓する時には、図１の破線のように再装入台車のケーブルが転炉炉下の地面レベルに敷設した状態となる。
【０００４】
【発明が解決しようとする課題】
上記従来の状態では、排滓の際に、転炉からスラグが排滓鍋に落下した跳ね返りなどで地面レベルに敷設したケーブルに溶融スラグの飛沫が飛び、ケーブルを損傷するケースがあった。
ケーブルを損傷した場合には、その復旧に長時間かかり、転炉の生産休止や修繕コストなどの増加を招いていた。
【０００５】
また、上記のケースばかりでなく、通常の転炉吹錬中のスロッピングなどによりケーブルを損傷するケースも考えられる。
【０００６】
【課題を解決するための手段】
本願発明は、上記問題を有利に解決するものであり、その要旨は、下記（１）〜（３）のとおりである。
（１）転炉の炉下を走行し、ケーブルによってその動力源を供給される台車を有する製鋼設備であって、前記台車に動力源を供給するケーブルが上下に昇降する機能を有することを特徴とする製鋼設備。
【０００７】
（２）転炉炉下に転炉から排出するスラグを受ける排滓鍋と、転炉から払い出した溶鉄を再度転炉に装入するための再装入鍋と、転炉にて最終精錬を施した溶鋼を受ける受鋼鍋とを有する製鋼設備において、少なくとも前記再装入鍋を運搬する台車のケーブルが上下に昇降する機能を有することを特徴とする（１）記載の製鋼設備。
【０００８】
（３）前記ケーブルが排滓あるいは、出鋼などの作業の開始あるいは終了タイミングにより自動的に昇降する機能を有することを特徴とする（１）または（２）記載の製鋼設備。
【０００９】
【発明の実施の形態】
以下、本願発明を詳細に説明する。
図１の実線は、本願発明の製鋼設備の一実施例の台車ケーブルを示したものである。
本例では、排滓鍋台車側から敷設されたケーブルは従来であれば、破線の状態となっているが、本願発明のケーブルの昇降機能を有した設備とすることによって、実線のようにケーブルが上昇可能なので、排滓時の溶融スラグの飛沫やあふれ出たスラグによるケーブル損傷を回避でき、転炉の生産休止や修繕コストの増加を未然に回避することができる。
【００１０】
また、排滓開始など作業のタイミングあるいは各台車の動きを検知し、自動的にケーブルを昇降することも可能である。
ここで本願発明において、ケーブル昇降装置は特に限定するものではない。例えば、図２のような昇降装置でもよい。図２は、昇降架台上を上下する昇降台車に水平なバーを取り付け、そのバーの上にケーブルを置く方式のものである。ケーブルは台車が移動するときに巻き取ることができるよう昇降装置には束縛することなくバーの上に置いているのみである。
【００１１】
【発明の効果】
本願発明により転炉炉下に配備された台車に動力源を供給するケーブルが転炉から払い出されるスラグや溶鉄の飛散や溢れ出によって損傷することを防ぐことができ、生産休止の低減、あるいは修繕費の削減が可能となった。

BACKGROUND OF THE INVENTION
The present invention relates to a steelmaking facility having a carriage for transporting molten iron or the like under a converter furnace.
[0002]
[Prior art]
Recently, it has become widespread that hot metal pretreatment is performed in a converter. Among them, there is a method of performing dephosphorization processing and decarburization processing in one converter. At that time, the molten iron refined in the converter is once discharged into a dedicated pan, the slag remaining in the converter is discharged, and then the molten iron once discharged into the dedicated pan is reloaded into the same converter again. Holds a special pot to enter (hereinafter referred to as a refill pan). Therefore, in the conventional converter, there are two trolleys for transporting the slag pan that receives the discharge slag, the steel pan that receives the molten steel after refining, and each pan.
[0003]
Further, when the hot metal preliminary treatment is performed in a converter, the recharging pan is transported (hereinafter referred to as a recharging cart), and three carts are arranged under the furnace. The recharging cart is located between the waste pan and the steel pan. Therefore, the cable for supplying the power source of the recharging cart is drawn from either the waste cart or the steel receiving cart side. For example, when the cable is drawn from the waste cart side, the cable is as shown in FIG. . Conventionally, when slag is discharged from the converter, the cable of the recharging cart is laid on the ground level below the converter furnace as shown by the broken line in FIG.
[0004]
[Problems to be solved by the invention]
In the above-described conventional state, there has been a case in which the molten slag splashes on the cable laid on the ground level due to the rebound of the slag falling from the converter to the slag pan during the sewage and damages the cable.
When a cable was damaged, it took a long time to restore it, leading to a suspension of converter production and an increase in repair costs.
[0005]
In addition to the above case, there may be a case where the cable is damaged by slopping or the like during normal converter blowing.
[0006]
[Means for Solving the Problems]
The present invention advantageously solves the above problems, and the gist thereof is as follows (1) to (3).
(1) A steelmaking facility having a cart that travels under a converter and is supplied with a power source by a cable, wherein the cable that supplies the power source to the cart has a function of moving up and down. Steel making equipment.
[0007]
(2) A waste pan that receives the slag discharged from the converter under the converter, a recharging pan for recharging the molten iron discharged from the converter, and final refining in the converter The steelmaking facility having a steel pan for receiving the molten steel applied, wherein the cable of the cart carrying at least the recharging pan has a function of moving up and down.
[0008]
(3) The steelmaking facility according to (1) or (2), wherein the cable has a function of automatically moving up and down depending on a start timing or an end timing of work such as discharging or steeling.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail.
The solid line in FIG. 1 shows the bogie cable of one embodiment of the steel making facility of the present invention.
In this example, the cable laid from the waste pan dolly side is conventionally in the state of a broken line. Therefore, it is possible to avoid the damage of the cable due to the splash of molten slag and the overflowing slag at the time of evacuation, and it is possible to avoid the stoppage of converter production and the increase in repair costs.
[0010]
It is also possible to automatically raise and lower the cable by detecting the timing of work such as the start of evacuation or the movement of each carriage.
Here, in this invention, a cable raising / lowering apparatus is not specifically limited. For example, a lifting device as shown in FIG. 2 may be used. FIG. 2 shows a system in which a horizontal bar is attached to an elevator car that moves up and down on the elevator frame, and a cable is placed on the bar. The cable is simply placed on the bar without being tied to the lifting device so that it can be wound up as the carriage moves.
[0011]
【The invention's effect】
According to the present invention, it is possible to prevent the cable that supplies the power source to the cart installed under the converter furnace from being damaged by the slag or molten iron splashed or overflowed from the converter, reducing production suspension or repairing. Costs can be reduced.
[Brief description of the drawings]
FIG. 1 is an overall view of a steelmaking facility showing a position example of the present invention.
FIG. 2 is a diagram illustrating an example of a lifting device that lifts and lowers a cable.
