この発明は、連続鋳造装置、特に、水へＩと連続鋳造装
置用バニシングロール装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous casting apparatus, and more particularly to a burnishing roll apparatus for a continuous casting apparatus.
近年、鋳型下部から鋳片を丁方に引き抜く垂直連続鋳造
法に代わりに、鋳型側部から鋳片を水平に引き抜く水平
連続鋳法が実用化されつつある。In recent years, instead of the vertical continuous casting method in which the slab is pulled out horizontally from the bottom of the mold, a horizontal continuous casting method in which the slab is pulled out horizontally from the side of the mold has been put into practical use.
この水平連続鋳造法は、垂直連続鋳造法に比べて設備費
を軽減できる等の利点を有する。This horizontal continuous casting method has advantages such as being able to reduce equipment costs compared to the vertical continuous casting method.
水平連続鋳造法に訃いて１通常１、鋳片は鋳型から間欠

一定時間引き抜きを停止し、その後再び一定時間鋳片を
引き抜くことを繰り返し行ない、これによって、餌型内
の凝固シェルが鋳型内面に焼き付くのを防止し、円滑な
鋳片引き抜きを図っている。In the horizontal continuous casting process, the slab is usually withdrawn from the mold intermittently. ff1J After pulling out the slab for a certain period of time, stopping the drawing for a certain period of time, and then pulling out the slab again for a certain period of time, this is repeated. This prevents the solidified shell in the bait mold from sticking to the inner surface of the mold, and ensures smooth casting. We are trying to pull out one side.
鋳片を間欠的に鋳型から引き抜くことによって。By intermittently pulling the slab out of the mold.
鋳片表面には、所謂、コールドシャットと呼ばれる疵が
発生する。Flaws called so-called cold shuts occur on the surface of the slab.
従来、コールドシャットを無くす方法として鋳片表面を
圧延ロールにより圧ドする方法があるが、次の如き問題
を有する。Conventionally, as a method of eliminating cold shut, there is a method of pressing the surface of the slab with a rolling roll, but this method has the following problems.
■、コ〜ルドシャットの完全除去を図るために、圧下ｆ
を大きくすると、鋳片の引抜制御に支障を来たす。■In order to completely remove the cold shut, reduce the pressure f.
If the value is increased, it will be difficult to control the drawing of the slab.
■、コールドシャットは鋳片全周に発生してい、６＋７

タンドはかなりのスペースを要する。このために鋳型直
後の狭いスペースに、圧延ロールを設置することが困難
である。■、Cold shut occurs around the entire circumference of the slab, 6+7
) Qi',: Roll stands for removal by rolling & rolling require considerable space. For this reason, it is difficult to install rolling rolls in a narrow space immediately after the mold.
■、正圧下加えることにより鋳片形状に変形が生じる。(2) The shape of the slab is deformed by applying positive pressure.

徴を有する。This invention was made in order to solve the above-mentioned problem, and is provided on the outer periphery of a slab having a circular cross section manufactured by a horizontal continuous casting machine, and is capable of being freely transferred along the outer circumferential surface of the slab. It is characterized by the fact that it is equipped with rolls that can adjust the rolling reduction amount.
