【発明の詳細な説明】
本発明は取鍋精錬装置、殊に真空取鍋精錬装置
におけるスロツピング対策装置に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for preventing slopping in a ladle refining device, particularly in a vacuum ladle refining device.
取鍋に直接カバーをかぶせ取鍋内を真空にして
溶鋼の脱ガスを行う真空取鍋精錬装置が近年実施
されているが、スロツピング対策が講じられてい
ないと下記の欠点を生ずる。 Vacuum ladle refining equipment has been implemented in recent years in which the ladle is directly covered with a cover to create a vacuum inside the ladle to degas the molten steel, but if measures against slopping are not taken, the following drawbacks occur.
(1) スロツピングが生じた時に取鍋鋼板とカバー
鋼板とが溶着する。(1) When sloping occurs, the ladle steel plate and cover steel plate are welded together.
(2) 真空取鍋精錬装置でスロツピングが生じる
と、真空シールパツキンを焼損する。(2) If slopping occurs in vacuum ladle refining equipment, the vacuum seal gasket will burn out.
(3) スロツピングによる溶着が生じて取鍋が移動
できなくなる。(3) Welding due to slopping occurs and the ladle cannot be moved.
本発明は上記のごときスロツピング発生時にお

供せんとするものであつて、取鍋上部、取鍋上部
外面、取鍋フランジ凹部及びカバー下部の凸部内
面を耐火材で被覆し、真空シール面を一段高くす

損を防止し、万一溶着が生じた場合でも取鍋の移
動が可能であるようにするものである。 The present invention aims to provide a sloping countermeasure device for preventing defects in the ladle refining device when sloping occurs as described above and allowing continuation of the refining operation. The outer surface, the concave part of the ladle flange, and the inner surface of the convex part at the bottom of the cover are coated with fireproof material to raise the vacuum sealing surface one step higher, and the concave part of the ladle flange is lined with flexible fireproof material to weld and seal the ladle and cover. This prevents burnout of the ladle and allows the ladle to be moved even if welding occurs.
スロツピングが生じた時に解決すべき点として
は下記のものがある。 The following points need to be resolved when sloping occurs.
(1) 取鍋上面のレンガ押え（鋼板）と取鍋中蓋
（鋼板）の溶着。(1) Welding of the brick holder (steel plate) on the top of the ladle and the inner lid of the ladle (steel plate).
(2) 取鍋上部外面（鋼板）とカバー下部内面（鋼
板）の溶着。(2) Welding of the outer surface of the upper part of the ladle (steel plate) and the inner surface of the lower part of the cover (steel plate).
(3) 真空シールパツキンの焼損。(3) Vacuum seal gasket burnt out.
(4) 上記部分に溶着が生じた場合でも取鍋が移動
できること。(4) The ladle must be able to be moved even if welding occurs in the above areas.
本発明においてはこれらの諸点を解決するため
に次の諸点に改良を加えたものである。 In order to solve these problems, the present invention includes the following improvements.
(1) 取鍋上面を耐火材（レンガ、キヤスタ、モル
タル、他）とする。それにより取鍋中蓋の鋼板
との溶着を防止できる。(1) The top surface of the ladle should be made of refractory material (brick, caster, mortar, etc.). This can prevent welding of the inner lid of the ladle to the steel plate.
(2) 取鍋上部外面、フランジ部及びカバー下部内
面を耐火材（レンガ、キヤスタ、モルタル、
他）で被覆する。それにより取鍋とカバーの溶
着を防止できる。(2) The outer surface of the upper part of the ladle, the flange part, and the inner surface of the lower part of the cover are covered with refractory material (brick, caster, mortar,
etc.). This prevents welding of the ladle and cover.
(3) 取鍋フランジのシール面を一段高くする。そ
れによりシール材の焼損を防止できる。(3) Raise the sealing surface of the ladle flange one step higher. This can prevent the sealing material from burning out.
(4) 取鍋フランジの凹面に柔軟性のある耐火材
（モルタル、他）を敷きつめる。それによりカ
バー下部の凸部（カバーの胴板）がめり込み易
くなる。(4) Lay flexible fireproof material (mortar, etc.) on the concave surface of the ladle flange. This makes it easier for the convex portion at the bottom of the cover (the body plate of the cover) to sink into the cover.
(5) カバー下部（カバーの胴板）をカバーフラン
ジより長くする。それによりスロツピングによ
る溶鋼がシール部へ流出するのを防止する。つ
まり(4)項と相まつて“せき”を作る。(5) Make the lower part of the cover (cover body plate) longer than the cover flange. This prevents molten steel from flowing into the seal portion due to slopping. In other words, together with item (4), it creates a "cough".
(6) カバーを二分割にする。それにより取鍋上部
とカバー下部が溶着した場合でも、カバーの上
半分のみを取り除くことにより取鍋の移動が可
能となり、溶鋼を取鍋から取り出すことができ
る。(6) Divide the cover into two parts. As a result, even if the upper part of the ladle and the lower part of the cover are welded together, the ladle can be moved by removing only the upper half of the cover, and the molten steel can be removed from the ladle.
