Abstract
Description
【発明の詳細な説明】 本発明は連続鋳造機に於ける溶鋼注入ノズルに関する。[Detailed description of the invention] The present invention relates to a molten steel injection nozzle in a continuous casting machine.
スラブを製造する連鋳機として、鋳型の長辺側を各々移
動するベルトとし、短辺側を固定側板あるいはリングで
構成したものがある。Some continuous casting machines for producing slabs have moving belts on the long sides of the mold, and fixed side plates or rings on the short sides.
このようなス′ラブ連鋳機では板厚６０〜１５０１１０
！１％板幅９００〜１５００ｍと非常に細長い断面のも
のを鋳造速度５〜１５ ｍ ／ ｍｉｎと極めて高速で
鋳造する。In such a continuous slab casting machine, the plate thickness is 60~150110.
! A 1% plate with a width of 900 to 1500 m and a very long cross section is cast at an extremely high casting speed of 5 to 15 m/min.
従って細長い断面に如何にして多量の湯を流すかか大き
な問題となる。Therefore, the big problem is how to flow a large amount of hot water over a long and narrow cross section.
このようなものに対し、従来一般に用いられている中空
丸型ノヂルを用いようとしても１本では 。Even if you try to use a hollow round nozzle, which is commonly used in the past, for something like this, it won't work with just one.
これの径が大となり、狭い鋳型に挿入することができな
いし、多数の小径ノズルで鋳湯する場合は保守性が悪く
費用も大となるという問題がある。This has a large diameter and cannot be inserted into a narrow mold, and when casting with a large number of small diameter nozzles, maintenance is poor and costs are high.
本発明は、狭い鋳型内へも多量の溶鋼を注入しうるノズ
ルを提供することを目的とするもので、ノズル先端部か
ら鋳片引抜方向及び鋳片幅方向へ溶鋼を注入可能なノズ
ルとしたことを特徴とする。The purpose of the present invention is to provide a nozzle that can inject a large amount of molten steel even into a narrow mold, and the nozzle is capable of injecting molten steel from the tip of the nozzle in the slab drawing direction and the slab width direction. It is characterized by

このような鋳型ヘタ、ンディッシュ１に貯えられた溶鋼
２がノズル３から注入される。Into such a mold, molten steel 2 stored in the dish 1 is injected from the nozzle 3.
さて、第１図に於いてこの注入ノズル３の構造が大きな
問題となる。Now, in FIG. 1, the structure of this injection nozzle 3 poses a major problem.
本発明では第２．３図に示すようにノズルの断面はタン
ディツシュ側中大きく、鋳型内に挿入する部分で細長い
中”空孔を有するように形成される。In the present invention, as shown in Fig. 2.3, the nozzle has a large cross section on the tundish side, and is formed to have an elongated hollow hole at the part inserted into the mold.
第２．３図に於いて湯面２３以下に門人された。ノズル
の部分は板幅Ｂ方向に両側に流出孔２４．２５を有し、
且つ、ノズルの下部にも流出孔２６を有これにより鋳型
内各部えの流出が均一に行える。In Figure 2.3, he was discipled by Yumen 23 and below. The nozzle part has outflow holes 24 and 25 on both sides in the board width B direction,
In addition, there is also an outflow hole 26 at the bottom of the nozzle, which allows for uniform outflow from all parts within the mold.
鋳型より上部でのノズル形状は第２図に示すように厚み

は正確な機械加工が必要である。このためこの取付は部
分は加工が容易となる。よう円形状とするのが好ましい
。The nozzle shape above the mold is expanded in the thickness direction as shown in FIG. 2, and is connected to a tundish 1.9 short nozzle 22. In this case, short nozzle 2
If the connection between the injection nozzle 2 and the injection nozzle 3 is defective, the molten metal will leak from the gap, causing a big problem. This connection therefore requires precise machining. Therefore, this mounting part is easy to process. It is preferable to have a circular shape.
またストッパ２１は円形状をしているからショートノズ
ル２２の孔は円形状となっている午とが必要である。ま

にゆ交に従い注入ノズル３の上部は広くするように改善
したーものである。Further, since the stopper 21 has a circular shape, the hole of the short nozzle 22 needs to have a circular shape. Also, when making a circular shape like this, it is necessary to flow the amount of hot water required for casting, and for this purpose, the upper part of the injection nozzle 3 was made wider as it crosses toward the tundish side. It is.
本発明の別な実施例を第４．５．．６図に示す。Another embodiment of the invention is described in Section 4.5. ．． It is shown in Figure 6.

’Ｐ″イツシュとの取付開会は円形形状で行う。(2) Pouring of metal into the mold is done through two holes in the width direction and a hole in the bottom. Note that there may be many holes in the downward direction instead of one, but it is necessary to maintain the outflow ratio described later.
The installation opening with 'P' Itsh is done in a circular shape.
尚、鋳型えの流出量゛は通常はノズル幅ｒり鋳型幅は極
端μ犬であるから、鋳型内に均一に湯が廻るようにする
には幅方向か゛らの流出量を大にする必要がある。Furthermore, since the flow rate of the mold is usually extremely small compared to the nozzle width, it is necessary to increase the flow rate from the width direction in order to ensure that the hot water circulates uniformly within the mold. be.
鋳型の′挿入される部分のノズル中空孔の寸法は厚み゛
３０前後、幅は１００〜３００＋ｏ＋前後であるが、こ
れに対し鋳゛型断面は厚み６０〜１５０ｍｍ。The dimensions of the nozzle hollow hole in the inserted part of the mold are about 30mm thick and about 100 to 300+o+ wide, whereas the cross section of the mold is 60 to 150mm thick.
幅９００〜ｉ ｓ ｏ Ｏｍ＋＋であるから幅方、向と
鋳片用方向との流出比は１〜５と幅方向えの流出量を大
にするこ゛とが必要である。Since the width is 900~iso Om++, it is necessary to increase the outflow amount in the width direction so that the outflow ratio in the width direction and the slab direction is 1 to 5.
本発明によれば、小型のノズルで多量の溶融を注出でき
るので狭い鋳型の連続鋳造機を容易に実現できる。According to the present invention, since a large amount of melt can be poured out with a small nozzle, a continuous casting machine with a narrow mold can be easily realized.
