この発明は連続鋳造機のタンディツシュの溶鋼表面のス
ラグを掻き出すためのスラグ掻き出し装置に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a slag scraping device for scraping out slag from the surface of molten steel in a tundish of a continuous casting machine.
（従来の技術）
連続鋳造機において、溶鋼はし一ドルから直下のタンデ
ィツシュ内に供給され、タンディツシュ内のせき内でス
ラグを除かれ、せきに設けられた流通孔を通って、隣の
溶鋼供給室に供給され、ここから水冷鋳型内に連続的に
供給されている。(Prior art) In a continuous casting machine, molten steel is supplied from a tip into a tundish directly below it, slag is removed in a weir in the tundish, and the molten steel is supplied to the adjacent molten steel through a flow hole provided in the weir. from which it is continuously fed into a water-cooled mold.
ここで、せき内の溶鋼表面のスラグ量が多くなると上方
から流下供給される溶鋼の流れにスラグが巻き込まれて
下方に沈み、せきに設けられた流通孔を通って、隣の溶
鋼供給室に入り、そのまま水冷鋳型内に供給され、鋳片
に欠陥を生じさせてしまう。When the amount of slag on the surface of the molten steel in the weir increases, the slag gets caught up in the flow of molten steel supplied from above and sinks downward, passing through the circulation hole provided in the weir and flowing into the next molten steel supply chamber. It enters the mold and is fed into the water-cooled mold as it is, causing defects in the slab.
そこで、従来はせき内の溶鋼表面のスラグ量が多くなら
ないように、一定期間ごとにタンディツシュを交換する
か、せき内の溶鋼表面のスラグを人力で掻き出すか、タ
ンディツシュの耐火物の形状を無視して、せき内の溶鋼
表面のスラグをシリンダー等で掻き出すようにしていた
。Conventionally, in order to prevent the amount of slag on the surface of the molten steel in the weir from increasing, the tundish was replaced at regular intervals, the slag on the surface of the molten steel in the weir was manually scraped out, or the shape of the refractory of the tundish was ignored. Then, the slag on the surface of the molten steel in the weir was scraped out with a cylinder or the like.
しかし、一定期間ごとにタンディツシュを交換する方法
は、タンディツシュのための耐火物の費用がかかりすぎ
るという問題点があり、せき内の溶鋼表面のスラグを人
力で掻き出す方法は、その作業環境が高温で極めて危険
であるという問題点があり、せき内の溶鋼表面のスラグ
をシリンダー等で掻き出す方法は、耐火物の形状に除滓
装置が追従できず、滓掻効率が悪いという問題点があっ
た。However, the method of replacing the tundish at regular intervals has the problem that the refractory for the tundish is too expensive, and the method of manually scraping out the slag from the surface of the molten steel in the weir is difficult because the working environment is high temperature. This method has the problem of being extremely dangerous, and the method of scraping the slag off the surface of the molten steel in the weir with a cylinder or the like has the problem that the slag removing device cannot follow the shape of the refractory, resulting in poor slag scraping efficiency.
この発明は、かかる問題点を解決するためになされたも
ので、せき内の溶鋼表面のスラグを安全にしかも効率良
く掻き出すことかできるスラグ掻き出し装置を得ること
を目的とするものである。The present invention was made to solve these problems, and an object of the present invention is to provide a slag scraping device that can scrape out slag from the surface of molten steel in a weir safely and efficiently.

を備え、該レバーはシリンダ装置のシリンダーロッドと
連結したことにより上記問題点を解決したものである。The slag scraping device according to the present invention includes a truck on which a cylinder device is installed, a motor that moves the truck forward and backward in the width direction of the tundish, and an arm that is attached to the tundish side portion of the truck so as to be able to swing up and down in a cantilevered manner. and,
A sludge removing plate attached to the tip of the arm so as to be able to swing vertically, a lever integrally attached to the base end of the arm, and a spring attached to the upper part of the sludge removing plate and the lever. The above problem is solved by connecting the lever to the cylinder rod of the cylinder device.

される。In this invention, since the upper part of the slag removal plate and the cylinder rod of the cylinder device are connected by a spring, the spring is deflected at the same time as the sludge removal plate is pressed against the tundish wall, and the sludge removal plate moves outside the tundish wall. Due to the restoring force of the spring, the slag is efficiently scraped out from the tanditshu.
