残滓排出装置に係り、特に連続鋳造用タンディッシュに
適用して好適な残鋼残滓排出装置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for discharging residual steel from a molten metal container, and more particularly to a device for discharging residual steel that is suitably applied to a tundish for continuous casting.

鋳造に支障をきたすことになり、そのため各種の残鋼残
滓処理技術が開発されている。In recent years, continuous casting operations of different steel types have been increasing in order to improve the efficiency of casting. In the case where the steel type is changed during such continuous casting, the remaining steel at the end of the previous casting has to be changed. If the residue is not completely discharged, the next casting will be hindered, and therefore, various residual steel residue treatment techniques have been developed.
【０００４】連続鋳造が始まった当初の頃は、残鋼残滓
を排出させるためにタンディッシュを傾動装置により９
０°近くまで傾動させ、タンディッシュ内に残る残鋼残
滓を他の容器内に排出させるようになされていた。At the beginning of continuous casting, a tundish was tilted by a tilting device to discharge the residual steel residue.
By tilting to near 0 °, the residual steel residue remaining in the tundish is discharged into another container.
【０００５】しかしこの方式では傾動装置がきわめて大
掛りなものとなり、しかも操業を一時中断して排出作業
を行なわなければならなかった。[0005] However, in this method, the tilting device becomes extremely large-scale, and furthermore, the operation has to be interrupted to perform the discharging operation.

れるようになっている。[0006] For these reasons, a large-sized slide valve having an enlarged hole diameter of an ordinary slide valve for discharging residual steel residue has recently been used by being attached to the bottom of a tundish.

There is a tundish described in JP 210948. In this device, a dedicated hole for discharging residual steel residue is provided at the bottom of the tundish, and a sliding nozzle is provided below the discharge hole.

As disclosed in JP-A-63-63, a flapper that pivots around a point below a residual steel residue discharge hole provided at the bottom of a tundish to open and close the discharge hole, and a drive mechanism that opens and closes the flapper And closing the discharge hole with a flapper, and then filling the discharge passage with clogging sand.

などの問題点があった。However, in the case of using the above-mentioned large slide valve (including the one described in the former publication), even if the hole diameter of the slide plate brick is increased to about 60φ, the plate weight is not reduced. 10kg
For this reason, heavy work is required at the time of replacing the slide plate brick, and not only does the gripping mechanism of the plate brick and its driving device increase in size and cost, but also the mounting place on the tundish is restricted. There was a problem.

近の耐用性により左右されるものとなる。On the other hand, in order to facilitate the discharge of residual steel residue when the slide valve is opened, the upper nozzle of the slide valve is filled with sand, so that the molten steel does not come into direct contact with the plate brick. Although erosion is not affected, when the slide valve is opened on the other side, the vicinity of the residual steel residue discharge hole is subject to thermal shock and erosion of molten steel, so the useful life of the slide valve is near the residual steel residue discharge hole. Depends on the durability of the steel.

取付けることができず、安全性の面で問題があった。In the above-mentioned publication, the refractory lining material of the flapper has good durability, but when the residual steel residue is discharged, the flapper closes poorly due to the influence of slime or the like near the outlet of the residual steel residue discharge hole. In addition, due to its structure, a nozzle for preventing the residual steel residue from scattering cannot be attached to the lower part of the discharge hole, and there has been a problem in terms of safety.

It is an object of the present invention to provide a device for discharging a residual steel residue of a molten metal container which has a long life and can be obtained safely and at low cost.

As shown in (A), the hydraulic cylinder 10 is extended and the non-opening plate portion 7 is positioned directly below the mass brick 2 to close the lower end of the residual steel residue discharge hole 2a, and sand is filled in the discharge hole 2a. Filling 17 prevents outflow of molten steel.

Considering that it is difficult to construct and that if the position varies, sliding contact with the plate brick may occur and safety is impaired, the lower end surface of the mass brick 2 is not directly used as a sliding surface, and This figure shows a mode in which a perforated fixing plate 18 made of a material (refractory material) suitable as a sliding surface is interposed at a lower surface position by a mortar set.

The hole diameter of the fixing plate 18 is set to be the same as the hole diameter at the lower end of the residual steel residue discharge hole 2 a of the mass brick 2.

In addition to being able to reduce the cost, there is no restriction at the time of attachment to the molten metal container, and the plate brick can be divided into a non-opening plate portion and an opening plate portion. By doing so, the weight can be reduced even at the time of setting, so that the heavy muscle work can be eliminated, and the workability can be significantly improved.
