【考案の詳細な説明】
本考案は、製鋼工場の鋳込鍋の如き溶融金属容器用保温
蓋の改良に関するものであり、鋳込終了後容器を傾転さ
せて底部の溶融スラグを排滓する時に、自然落下するス
ラグが保温蓋に接触耐着して耐用寿命を著しく損うこと
を防止するためのものである。[Detailed description of the invention] The present invention relates to an improvement of a heat-insulating lid for a molten metal container such as a casting pot in a steel factory, and the container is tilted after casting to remove molten slag from the bottom. This is to prevent slag that sometimes naturally falls from coming into contact with the heat insulating lid and significantly reducing its useful life.
鋳込中の鋳込鍋に保温蓋を被せて鍋内の溶鋼の温度低下
を抑えること、および鋳込終了後排滓のときてもその内
部の温度低下を抑えるために保温蓋を被せることは、省
エネルギーの観点から必要なことであり、既に周知であ
る。It is recommended to cover the casting pot with a heat insulating lid during casting to suppress the drop in temperature of the molten steel inside the pot, and to cover the casting pot with a heat insulating lid to suppress the drop in internal temperature even when the slag is being discharged after casting. , which is necessary from the perspective of energy conservation and is already well known.
又、鋳込終了後排滓するときにも保温蓋を完全に取はず
すことなく、一部を被せたまま行うことも一部で実用さ
れている。Furthermore, it is also practiced in some cases to discharge the slag after the completion of casting, without completely removing the heat insulating lid, but leaving it partially covered.
第1図、第2図はこれらの従来の保温蓋の構造を示した
もので、第1図は前者の例であり、第2図は後者の例で
ある。1 and 2 show the structures of these conventional heat-retaining lids, with FIG. 1 being an example of the former, and FIG. 2 being an example of the latter.

である。In each figure, a is an elevational view, b is a plan view, and c is an external view showing the state when the casting pot is tilted to drain the molten slag at the bottom.
各図の1は鋳込鍋、2は保温蓋、第2図の2′は前記保
温M2の一部を別個に分割した剛着で蝶番7により保温
蓋2に固定されている。In each figure, 1 is a casting pot, 2 is a heat-insulating lid, and 2' in FIG. 2 is a rigid joint made by separately dividing a part of the heat-insulating M2, and is fixed to the heat-insulating lid 2 by a hinge 7.

然落下する溶融スラグが蓋2や剛着2′のキャスタブル
に接触耐着するので、耐用寿命の点では第1図のものと
あまり変りがなく、同様の問題があった。However, the heat-insulating lid having the structure shown in Fig. 1 has the problem that molten slag adheres to the castable at the end of the opening of the lid when discharging slag, significantly reducing the service life of the lid. The heat-insulating lid shown in the figure is more convenient for keeping the pot warm when it is empty than the heat-insulating cover shown in Fig. 1, but when the casting pot is tilted nearly 180 degrees at the end of slag removal, the heat-insulating lid shown in Fig. 2 Because the rigid joint 2' is small and the lid 2 is not fully open, the molten slag that naturally falls from the bottom of the pot comes into contact with the lid 2 and the castable of the rigid joint 2', so it is the best in terms of service life. It was not much different from the one in Figure 1, and had the same problem.
本考案は、上記の従来の保温蓋の問題点を解決するため
に創案されたものである。The present invention was devised to solve the above-mentioned problems of the conventional heat-retaining lid.
次に、本考案の溶融金属容器用保温蓋の構造を図によっ
て説明する。Next, the structure of the insulating lid for a molten metal container of the present invention will be explained with reference to the drawings.

態を示す外観図である。Figure 3 shows an embodiment of the insulating lid of the present invention, in which a is a plan view, b is an elevational view, C is an external view showing the casting pot tilted approximately 90 degrees, and d is an approximate view. It is an external view showing a state where it is tilted to nearly 180 degrees.

有することである。What is important in this invention is that the size of the side lid 13' is at right angles to the radial direction at a position corresponding to I15 to 1/2 of the diameter of the approximately circular lid made up of the engraftment 13 and the side lid 13'. The engraftment 13 has a size that occupies the remaining portion.

4には接触耐着せず、排滓が完全に行われる。Since the insulating lid for a molten metal container of the present invention has the above-described structure, even if it is tilted nearly 180 degrees, which was a problem with the conventional insulating lid shown in FIG.
As shown in Figure d, even when the degree of inclination during tilting is small and gradually increases, the side lid 13' is opened first, and then the engraftment 13 and the side lid 13' are gradually opened. As the temperature increases, castable 1 on the back of each heat-insulating lid 13.13'
No. 4 has no contact resistance and the slag is completely removed.
このことにより、従来の第1図、第2図の保温蓋のキャ
スタブルが100回程鹿の稼動で損傷し、補修を必要と
していたのに比べ、本考案による保温蓋は300回程回
程で補修せずに使用することができた。As a result, compared to the conventional castable heat-insulating lids shown in Figures 1 and 2, which were damaged and required repair after being operated by deer about 100 times, the heat-insulating lid according to the present invention does not need to be repaired after being used about 300 times. could be used for.
このため保温蓋の原単位が低減され、また保温蓋の常備
数を減すことが可能となった。As a result, the unit consumption of heat-insulating lids has been reduced, and it has also become possible to reduce the number of heat-insulating lids that are always on hand.
