Definitions
- the present invention relates to a keyboard structure that supports an immersion nozzle used for continuous casting of steel, and is particularly suitable for a keyboard structure in which an old immersion nozzle is pushed out horizontally with a new immersion nozzle and replaced. .
- Steel continuous casting is performed by transferring the molten steel in the ladle to a tundish and then pouring it into a mold from an immersion nozzle. Since the immersion nozzle is exposed to high temperature molten steel and wears out, the old worn immersion nozzle is replaced with a new immersion nozzle.
- the replacement of the immersion nozzle is generally performed by closing the upper molten steel flow path of the immersion nozzle with a sliding nozzle and extruding the old immersion nozzle with a new immersion nozzle in the horizontal direction.
- a piece for raising the flange portion In order to facilitate the replacement of the immersion nozzle and to support the flange portion at the upper end of the immersion nozzle by pushing it upward, a piece for raising the flange portion, generally called a keyboard, is used.

- the problem at the time of actual immersion nozzle replacement is that the extrusion device that pushes out the old immersion nozzle with the new immersion nozzle requires an excessive extrusion force, and the device stops. It has been found that it is sufficient to reduce the pushing force related to the pushing device without releasing the pressing of the flange contact end portion of the member.
- the keyboard structure for supporting the immersion nozzle supports the flange portion provided at the upper end portion of the immersion nozzle for continuous casting by pushing it upward and is provided in a plurality in a predetermined horizontal direction.
- substantially opposed arrangement means that the piece members are allowed to shift in the predetermined horizontal direction from the position of the opposed arrangement. In the present invention, if a part of the piece member is hung at the facing position, it is regarded as substantially facing.
- the inclined surface among the piece members opposed or substantially opposed to each other with the upper portion of the immersion nozzle interposed therebetween After the flange portion of the new immersion nozzle rides on the upper surface from the inclined surface of one piece member on one side in the predetermined horizontal direction, the inclined surface is formed on the inclined surface of the other piece member on the other side in the predetermined horizontal direction.
- the slopes of the piece members that are opposed or substantially opposed to each other across the upper part of the immersion nozzle are shifted in the predetermined horizontal direction so that the flange portion abuts.
- the slopes are shifted in the predetermined horizontal direction by shifting the piece members opposed or substantially opposed to each other across the upper part of the immersion nozzle in the predetermined horizontal direction. Further, the slope is shifted in the predetermined horizontal direction by changing the shape of the slope between the pieces facing each other or substantially opposed to each other across the upper part of the immersion nozzle.
- a plurality of piece members are disposed in a predetermined horizontal direction to support the flange portion provided at the upper end of the continuous casting immersion nozzle by pushing it upward.
- an opposed or substantially opposed arrangement with the upper part of the immersion nozzle in between, or a slope inclined downward on the one horizontal side of the predetermined horizontal direction on the upper side of the predetermined horizontal direction of each piece member.
- the inclined surfaces of the piece members are shifted in a predetermined horizontal direction.
- the slopes of the piece members that are opposed or substantially opposed to each other across the upper part of the immersion nozzle are predetermined horizontal.
- the flange part of a new immersion nozzle rides on the upper surface from the slope of one piece member on one side in the direction, and the flange part of the new immersion nozzle comes into contact with the slope surface of the other piece member on the other side in the predetermined horizontal direction.
- the pushing force required for the dipping nozzle extruding device can be reliably reduced by shifting the inclined surfaces of the piece members facing or substantially opposed to each other across the upper portion of the dipping nozzle in a predetermined horizontal direction.
- the invention can be easily implemented if the pieces of the piece members opposed or substantially opposed to each other with the upper part of the immersion nozzle are shifted in a predetermined horizontal direction so that the slopes of those piece members are shifted in the predetermined horizontal direction. Further, the invention can be easily implemented by changing the shape of the slope between the pieces facing each other or substantially facing each other across the upper part of the immersion nozzle to shift the slope of the pieces in the predetermined horizontal direction. .

Abstract
Description
本発明は、上記のような問題点に着目してなされたものであり、既設の連続鋳造機でも大がかりな改造を必要とせず、浸漬ノズルの交換を容易にする浸漬ノズル支持用鍵盤構造を提供することを目的とするものである。
ここで、略対向配置とは、駒部材が、対向配置の位置より前記所定水平個方向にずれることを許容する趣旨である。本発明においては、駒部材の一部が対向位置に掛かっていれば略対向とみなすものとする。
また、前記浸漬ノズル上部を挟んで対向又は略対向配置されている駒部材同士で前記斜面の形状を変更することにより前記斜面を前記所定水平方向にずらしてなるものである。
また、浸漬ノズル上部を挟んで対向又は略対向配置されている駒部材同士で斜面の形状を変更することによりそれらの駒部材の斜面を所定水平方向にずらすこととすれば、発明を実施し易い。
図1は、本実施形態の浸漬ノズル支持用鍵盤構造が適用されたスライディングノズル装置の正面図である。図の上方が実際の装置の上方になっている。スライディングノズル装置は、図示しない鋳型内の溶鋼に浸漬される浸漬ノズル1を支持すると共に、その浸漬ノズル1の上方で図示しないタンディッシュに連通する溶鋼流路を開閉するものである。このスライディングノズル装置は複数のノズルを上下方向に積層して構成される。このうち、溶鋼流路を開閉するスライディングノズル5は、上側固定ノズル部材2と下側固定ノズル部材3との間に摺動ノズル部材4を挟んで構成される。それぞれのノズル部材2~4にはノズル孔2a~4aが開設されており、それらのノズル孔2a~4aが図示のように連通していれば、タンディッシュと浸漬ノズル1とが連通状態(開状態)となる。一方、図示しない摺動ノズル移動装置によって、例えば摺動ノズル部材4を図の横方向に移動させてノズル孔4aが固定ノズル部材2、3のノズル孔2a、3aと連通しない状態とすればタンディッシュと浸漬ノズル1とが非連通状態(閉状態)となる。
前述のように、駒部材9は浸漬ノズル1の上部を挟んで対向又は略対向するように配置されているが、本実施形態では、浸漬ノズル1の上部を挟んで対向配置されている駒部材9を互いに前記所定水平方向にずらしている。すなわちこの構造により、当該浸漬ノズル1の上部を挟んで対向又は略対向配置されている駒部材9の斜面13を所定水平方向にずらしている。このように浸漬ノズル1の上部を挟んで対向又は略対向配置されている駒部材9の斜面13を所定水平方向にずらすと、新しい浸漬ノズル1′で古い浸漬ノズル1を押し出して交換する際、新しい浸漬ノズル1′のフランジ部8は、フランジ部8を挟んで対向又は略対向配置されている駒部材9のうち、斜面13が所定水平方向手前側、即ち図の左側(一方側)にある駒部材9の斜面13に当接し、次いで斜面13が所定水平方向先方側、図の右側(他方側)にある駒部材9の斜面13に当接する。このように浸漬ノズル1のフランジ部8が駒部材9の斜面13に当接するタイミングをずらす構造とすることにより、押し出し装置12の押し出し力を低減することができる。
また、浸漬ノズル1の上部を挟んで対向又は略対向配置されている駒部材9に形成される斜面13の形状を変更することにより、当該浸漬ノズル1の上部を挟んで対向又は略対向配置されている駒部材9の斜面13を所定水平方向にずらす場合の斜面13の形状は前記に限定されるものではない。
さらに、駒部材9の前記斜面以外の形状についても、図示されたものに限定されるものではない。
また前期押し上げ装置の構造も図示されたもに限定されず、弾性体、油圧、気圧、モーター等の力を、駒部材9を上方に押し上げる力に伝達する構造であればよい。
