【発明の詳細な説明】
本発明は、連続鋳造における注湯方法に関し、特に薄板
鋳片を直接鋳造する方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pouring method in continuous casting, and particularly to a method for directly casting thin plate slabs.
従来の鋳造技術、特に連続鋳造技術における注湯技術は
、鋳片の肉厚が１００〜３００■程度で、幅が１００〜
２，０００■程度と大きいことから、注湯流の流径を大
きく（例えば１０〜３０霧φ）でき、かつノズル本体を
鋳型内の湯面下１で下けて注湯できるので注湯流が酸化
することもなく注湯できた。しかし、最近は薄板を直接
鋳造できる技術、すなわち従来の粗圧延工程の省略をね
らった薄板の連続鋳造技術の開発ニーズが高まって来た
。Conventional casting technology, especially pouring technology in continuous casting technology, has a thickness of about 100 to 300 cm and a width of about 100 to 300 cm.
Since it is large at about 2,000 mm, the flow diameter of the pouring flow can be increased (for example, 10 to 30 mm φ), and the nozzle body can be lowered to 1 below the molten metal level in the mold to improve the pouring flow. It was possible to pour hot water without oxidation. However, recently there has been an increasing need to develop a technology that can directly cast thin plates, that is, a continuous thin plate casting technique that aims to omit the conventional rough rolling process.
従来の注湯技術では、この薄板連続鋳造に対応できない
。すなわち、鋳片の大きさが、肉厚２〜１０■２幅ｊ、
ｏ ｏ ｏ〜１．５００ ｗ程度となると従来の円孔

ばならなく彦る。Conventional pouring technology cannot support this continuous thin plate casting. In other words, the size of the slab is 2 to 10 mm thick, 2 wide j,
o o o~1.500 W, it becomes necessary to use a slit-shaped nozzle instead of the conventional circular hole-shaped nozzle.
そこで本発明は、スリット状ノズルを使用する注湯方法

リット状に溶湯を供給することを特徴とする注湯方法に
関するものである。That is, the present invention uses a wide slit-shaped nozzle as a pouring nozzle in a method of pouring metal into a mold part in a continuous casting method, embeds a resistor in the nozzle part, and heats and keeps the nozzle part warm by energizing it. The present invention relates to a pouring method characterized by pressurizing the molten metal using gas pressure and supplying the molten metal from a nozzle portion to the next process in the form of a wide slit.

を良好に連続鋳造するものである。In the method of the present invention, in a ladle having a slit-shaped nozzle, the nozzle part is heated by direct current heating with a resistor to prevent solidification of molten steel, and gas pressure is used as the driving force for pouring. It allows continuous casting of wide and thin slabs.

１図の一部拡大図である。FIG. 1 shows a sectional view of a ladle and its accessories applied to the method of the present invention, FIG. 2 is an external view of FIG. 1, and FIG. 3 is a partially enlarged view of FIG. 1.
第１図において、取鍋１の内部は堰２で２室に分けられ
ている。In FIG. 1, the inside of a ladle 1 is divided into two chambers by a weir 2.
１室は導圧管３を有し、他室はノズル４を有している。One chamber has a pressure impulse pipe 3, and the other chamber has a nozzle 4.
ノズル４には、溶鋼５と接する壁面の近傍に抵抗体６が
埋め込まれている。抵抗体６は、第３図に示すように、
電源７に接続される。A resistor 6 is embedded in the nozzle 4 near the wall surface in contact with the molten steel 5. As shown in FIG. 3, the resistor 6 is
Connected to power supply 7.
溶鋼５は導圧管３の取シ付いた蓋８を開いて、受湯口９

次の工程へ供給される。The molten steel 5 is poured into the molten metal by opening the lid 8 with a handle on the impulse pipe 3 and passing it through the receiving port 9.
Supplied from. After a predetermined amount of molten steel 5 is poured into the ladle 1, the lid 8 is closed and an inert gas (Ar,
N2, etc.) is supplied, the pressure in the pressure chamber 10 rises, and the molten steel 5 moves toward the nozzle 4 and is supplied from the opening 11 of the nozzle 4 to the next process.
抵抗体６を通電によって発熱させ、ノズル４を加熱、保
温することにより、溶鋼５がノズル４を通過するときに
溶＠５が凝固しないようにしている。By energizing the resistor 6 to generate heat and heating the nozzle 4 and keeping it warm, the molten steel 5 is prevented from solidifying when it passes through the nozzle 4.

た省エネルギーの面でも有益である。As described above, the method of the present invention uses a wide slit nozzle, which is necessary when continuously casting wide and thin slabs, to pour the metal, so a conventional circular hole nozzle can be used to cast large-sized slabs. It is possible to omit the step of rough rolling after casting a piece, and it is also beneficial in terms of energy saving.

の広幅スリットとはせずに、第６図に示すように、分割
したスリット状開口部とすることもできる。Furthermore, from the viewpoint of structure and strength, the shape of the nozzle opening 11 of the wide slit nozzle used in the method of the present invention is not a single wide slit, but a divided slit as shown in FIG. It can also be a shaped opening.
また、本発明方法は、気体圧力を利用することＫよシ、
ノズル開口部１１から流出する溶鋼量の制御も簡単にで
き、抵抗体加熱により、狭い開口部でも溶鋼の凝固を伴
うことなく注湯できる。In addition, the method of the present invention uses gas pressure,
The amount of molten steel flowing out from the nozzle opening 11 can be easily controlled, and by heating the resistor, it is possible to pour molten steel even into a narrow opening without solidifying the molten steel.
なお、本庄湯方法は、溶鋼のみでなく、他の溶融金属に
も適用できる。Note that the Honjo Yu method can be applied not only to molten steel but also to other molten metals.
