【考案の詳細な説明】 この考案は、転炉内保温用加熱装置に関するもので、転
倒させた転炉炉口に装着し、バーナーを使って炉内を加
熱保温する装置について提案する。
[Detailed description of the invention] This invention relates to a heating device for keeping the inside of a converter furnace warm, and proposes a device that is attached to the mouth of an overturned converter furnace and uses a burner to heat and keep the inside of the furnace warm.

最近の転炉精錬というのは、連鋳比率の増大に伴ない、
連鋳機の操業状況に左右されることが多く、そのために
しばしば間欠的な操業となっているのが実情である。
Recent converter refining has increased the continuous casting ratio,
The reality is that it is often affected by the operating conditions of the continuous casting machine, and as a result, it is often operated intermittently.

このように間欠的に操業している転炉の場合、とくにそ
れが休止のときには、炉内の温度低下が著しく、炉体れ

くする欠点が見られた。
In the case of a converter that operates intermittently in this way, especially when the converter is not in operation, the temperature inside the furnace drops significantly, causing thermal spalling of the furnace bricks, which shortens the life of the furnace. It was seen.

Moreover, since it promotes the adhesion and growth of metal at the furnace mouth, it also has the disadvantage of interfering with furnace operation, such as charging the charge.

Conventionally, as a countermeasure, a simple furnace lid was attached to the furnace mouth of the converter while the furnace was out of operation, and a lid was installed to compensate for the gap that was inevitably created due to the adhesion of base metal. A small-diameter combustion gas pipe (coke oven gas) or oxygen gas pipe was inserted into the furnace and burned to keep the inside of the furnace warm.

However, in the case of this conventional technology, it takes time and effort to install the pipes and cover the furnace lid, and only small-diameter pipes can be used to insert the pipes using the gaps, so the amount of fuel gas is small and the flame is low. Since it is short, there is a drawback that it is not possible to maintain sufficient heat in the furnace commensurate with the heat dissipation from the gap.

この考案の目的は、上述の従来技術のもつ欠点を克服す

The gist of this is that a pedestal is installed on a trolley that moves on a track, and on this pedestal, a furnace cover that closes the opening of the converter furnace, which opens downward in an overturned state, can be raised and lowered via an elevator. In the converter heat insulation device, a combustion burner is attached to the furnace lid facing upward facing into the converter furnace, and an air pipe and a fuel pipe extending from the lower end of the burner are each provided with one end of a retractable pipe. is fixed, and the other ends of these expandable tubes are connected to blowers mounted on trolleys, or as connecting ends to the original piping on the ground side.

以下にその構成の詳細を図面を参照して説明する。The details of the configuration will be explained below with reference to the drawings.

この考案加熱装置は、取鍋輸送台車のための軌道上を移
動させる台車1に設置されているものである。
This invented heating device is installed on a truck 1 that moves on a track for a ladle transport truck.

したがって転炉の精錬を休止して炉内を保温する必要の
あるときに、前記台車1を移動させて該転炉の炉体2直
下に停車させればよいのである。
Therefore, when it is necessary to suspend the refining of the converter to keep the inside of the furnace warm, the cart 1 can be moved and stopped directly below the furnace body 2 of the converter.

上記台車1上に、数本の支柱を立設して構成される架台
3を設ける。
A pedestal 3 is provided on the cart 1, which is constructed by erecting several pillars.

The furnace lid 6 includes an elevator motor 9 and a gear box 7,
Due to the operation of the elevator 4, which is repeatedly struck via the threaded rod 8,
The elevating rod 4a moves up and down to move up and down, and in turn moves to be pressed against the furnace mouth 2a or to stand by on the pedestal 3 (in a lowered state).

The above-mentioned furnace lid 6 is equipped with an upward combustion burner 10 that faces the inside of the converter furnace in an overturned state, and an air pipe 11 and a fuel pipe 12 extending from the bottom of the burner 10 are each provided with a bellows shape. The telescopic tubes 13 and 14 are attached.

ある。
In this way, the blower 5 and the main pipe 16 are connected to the air pipe 11 and the fuel pipe 12 through the telescopic pipes 13 and 14 because the former is fixed to the burner 10 and the furnace lid 6 is connected to the air pipe 11 and the fuel pipe 12.
This is because while the latter is fixed to the pedestal 3, a buffer between the two is required.

上述のように構成された本考案加熱装置は、出鋼後休止
させる転炉を転倒させ、下向きになるそれの炉口2aに
押当てて保温するものである。
The heating device of the present invention configured as described above inverts the converter, which is to be shut down after tapping the steel, and presses it against the furnace mouth 2a facing downward to keep the converter warm.

すなわち、かかる転炉直下に前記台車1を移送させ、昇
降機4を介して炉蓋6を上昇させ、炉口2aに押付ける
That is, the cart 1 is transferred directly below the converter, and the furnace lid 6 is raised via the elevator 4 and pressed against the furnace mouth 2a.

もちろん、その炉口2a面には多少の違いはあっても、
地金が付着しているので、密閉はできない。
Of course, even though there are some differences in the furnace mouth 2a side,
Since the metal is attached, it cannot be sealed.

しかし、その隙間は後述のバーナー燃焼にともなう排気
上必要である。
However, this gap is necessary for exhaust gas accompanying burner combustion, which will be described later.

つぎに、炉蓋6に取付けたバーナー10に点火して燃焼

As explained above, according to the heating device according to this invention, unlike the case where a very small diameter fuel gas pipe is inserted through the narrow gap created by the metal adhering to the furnace mouth, the burner can be directly inserted into the furnace lid. Because it is attached, there are no restrictions like in the past.
Large diameter gas pipes can be used.

したがって、炉内を保温するに十分な熱量を供給するこ
とができ、熱スポーリングの減少による炉寿命の延長が
果される。
Therefore, sufficient heat can be supplied to keep the inside of the furnace warm, and the life of the furnace can be extended by reducing thermal spalling.

また、炉口への地金付着が減少するので、熱放散の減少
とともに炉操業を便利なものとする。
Furthermore, since metal adhesion to the furnace mouth is reduced, heat dissipation is reduced and furnace operation becomes convenient.

さらに、保熱性がよいから炉体煉瓦温度を上昇させるこ
とができ、鉄鉱石の使用量を増量しても熱補償が得られ
