【考案の詳細な説明】
本考案は、出鋼］−二１にスライテ゛イングゲ−１・を
付設した転炉から出鋼を受ける取鍋に関し、低水素鋼を
得るとともに合金の添加歩留を向上することを目的とし
てなされたもので゛ある。[Detailed description of the invention] The present invention relates to a ladle for receiving steel tapping from a converter in which a slitting gauge 1 is attached to the tapping steel. It was done for the purpose of improving.
目に示ず一実施例に基ついて説明すれば、１は取鍋本体
であり、該取鍋本体１の上端開門には取鍋蓋２が装着固
定されている。To explain based on one embodiment, not shown, 1 is a ladle main body, and a ladle lid 2 is attached and fixed to an opening at the upper end of the ladle main body 1.

ゲー １〜Ｂを開動作して出鋼を開始する。The present invention has a structure as described in the embodiments above, and before tilting the converter A to tap steel, first move the trolley to an appropriate position corresponding to the converter A, and then Dry inert gas is supplied via piping 7 to injection nozzles 5 and 6.
The air in the ladle is replaced with the dry inert gas by injecting it into the ladle, and then the converter A is tilted and the tapping nozzle C is placed in the receiving port 3 to insert the steel into the ladle. Open the game 1 to B to start tapping.
なお出鋼中は、転炉Ａの傾動と台車りを動作させること

る。During tapping, work continues while synchronizing the tilting of the converter A and the movement of the ladle by operating the trolley.
又合金鉄は予め取鍋中へ、入直するか又は出鋼後に真空
脱ガス装置等で゛添加する。In addition, the ferroalloy can be added to the ladle in advance, either by reinserting the ladle or by using a vacuum degassing device or the like after tapping.

目的が完全に達成で゛きる。According to the present invention, the ladle lid 2 provided with the steel receiving port 3 and the peephole 4 is attached and fixed between the upper ends of the ladle body 1, and the inner wall of the ladle lid 2 and the steel receiving port are mounted on the ladle body 1. Dry activated gas injection 7 nozzles 5 and 6 are installed on the inner wall of the ``-13'', and gas supply piping 7 is attached to these, and the air in the ladle is replaced with dry inert gas before tapping. In addition, since the tapping flow and the inside of the ladle can be isolated from the atmosphere, the intended purpose of obtaining low hydrogen steel and improving the alloy addition yield can be completely achieved.
