本発明は無限軌道式連鋳機のナイフ装置に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a knife device for a continuous track casting machine.
［従来の技術］ 無限軌道式連鋳機を第７図により説明する。[Conventional technology] The endless track type continuous casting machine will be explained with reference to FIG.

方に突出させたタンデイツシュノズル９を挿入し、且つ
鋳型空間３下流の開口部に複数の案内用のガイドロール
１０を回転自在に支持するフレームｎを上下に備えたナ
イフ装置１２を設ける。A mold 2 is formed by connecting a large number of block molds 1 in an endless track, and the molds 2 are combined vertically to form a mold space 3 in opposing parts, and an inclined cooling zone 4 is provided downstream of the mold space 3. and a horizontal cooling zone 5, and cooling devices such as a mist coolant device 6 and a coolant chamber 7 are arranged in the inclined cooling zone 4 and the horizontal cooling zone 5, respectively,
A frame for inserting a tundish nozzle 9 protruding forward from the lower part of the tundish 8 into an opening upstream of the mold space 3, and rotatably supporting a plurality of guiding guide rolls 10 at a downstream opening of the mold space 3. A knife device 12 having upper and lower blades is provided.
尚、１３は駆動用のギア、１４は従動用のギア、１５は
鋳片である。Note that 13 is a driving gear, 14 is a driven gear, and 15 is a slab.
駆動用のギア１３を回転駆動して鋳型２を図中矢印ａ方
向に移動し、タンデイツシュ８に注入された溶湯をタン
デイツシュノズル９から鋳型空間３に供給すると、鋳型
空間３に供給された溶湯は鋳型２により冷却、凝固され
鋳片Ｉ５となって鋳型空間３下流から取出される。The driving gear 13 is rotationally driven to move the mold 2 in the direction of the arrow a in the figure, and the molten metal injected into the tundish nozzle 9 is supplied to the mold space 3 from the tundish nozzle 9. The molten metal is cooled and solidified by the mold 2 to become a slab I5 and taken out from the mold space 3 downstream.
この際、鋳型空間３下流から取出された鋳片１５が、完
全に凝固せず内部に溶湯が残りているいわゆる未凝固鋳

湯に掛るので、鋳片１５は鋳型空間３から取出された直
後に膨張（いわゆるバルジング）してしまい、或いは又
最悪の場合にはタンデイツシュ８の鉄静圧により凝固し
た外殻か破れて鋳片破壊を起こしてしまう。At this time, if the slab 15 taken out from the downstream of the mold space 3 is a so-called unsolidified slab that has not completely solidified and molten metal remains inside (the mold space 3 should be set as short as possible). As the slab 15 is removed from the mold space 3, the static iron pressure of the tundish 8 is applied to the molten metal inside the slab 15. This may cause expansion (so-called bulging), or in the worst case, the solidified outer shell may be torn due to the iron static pressure of the tundish 8, causing slab failure.
そこで、このような鋳片Ｉ５のバルジングや鋳片破壊を
防止するために、鋳型空間３下流の開口部にナイフ装置
１２を設けて、鋳型空間３から取出された直後の鋳片１
５を、ナイフ装置１２のガイドロール１０により上下か
ら挟持しつつ下流に送るようにしてバルジングや鋳片破
壊を防止している。Therefore, in order to prevent such bulging and slab breakage of the slab I5, a knife device 12 is provided at the downstream opening of the mold space 3, and a knife device 12 is provided at the downstream opening of the mold space 3 to prevent the slab 1 from being taken out from the mold space 3.
5 is conveyed downstream while being held between the upper and lower sides by the guide rolls 10 of the knife device 12 to prevent bulging and slab breakage.
［発明が解決しようとする課題］

鋳片１５の鋳造を行い、取出された鋳片１５を連続して
送るうちにガイドロール１０の表面が鋳片１５により摩
耗されて、ガイドロールｌＯの表面に第８図に示すよう
な段差すが生じてしまう。[Problems to be Solved by the Invention] However, the knife device 12 described above casts slabs 15 of the same plate width, and as the slabs 15 taken out are continuously fed, the surface of the guide roll 10 becomes uncast. The piece 15 is worn away, and a step as shown in FIG. 8 is formed on the surface of the guide roll IO.
このように、ガイトロールＩＯの表面に段差すが生じる

ガイドロール表面１０の段差すで鋳片１５が傷付いたり
、タンデイツシュ８のＶ、静圧により鋳片１５が膨張し
て段差す内に入り込み段差のある鋳片１５ができてしま
ったりして、鋳片１５の品質が悪化するという問題があ
った。In this way, if a step occurs on the surface of the guide roll IO, when the plate width of the slab 15 to be cast is changed to a wider one,
The slab 15 may be damaged by the step on the surface of the guide roll 10, or the slab 15 may expand due to the V of the tundish 8 and static pressure and enter the step, resulting in a slab 15 with a step. There was a problem that the quality of the slab 15 deteriorated.

の中間ダムを設けた場合に中間ダムがナイフ装置１２と
干渉してしまうという問題があった。In addition, in recent years, simultaneous casting, for example, mold space 3, in which the mold space 3 is partitioned into a plurality of parts by an intermediate dam for width division, and multiple rod slabs 15, especially multiple rod slabs 15 having different plate widths, is simultaneously cast. Twin casting involves dividing the mold space into two sections with an intermediate dam and simultaneously casting 20 rod slabs I5 with different widths, or dividing the mold space into three sections with two intermediate dams and casting 15 rod slabs with different widths. Triple casting, etc., in which the blades are cast at the same time, has been considered, but when an intermediate dam for width division is provided, there is a problem that the intermediate dam interferes with the knife device 12.
