BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for discharging waste from a continuous casting facility. More specifically, residual steel and slag discharged from a tundish after pouring into a mold (hereinafter referred to as slag)
The present invention relates to a waste discharging device for discharging waste water.

[0002]

2. Description of the Related Art After a molten metal is poured into a continuous casting mold, slag is left inside a tundish. This slag is composed of CaO, phosphorus, sulfur, etc. in addition to metal components. If the amount is too large, phosphorus, sulfur and the like are eluted in the molten metal poured into the tundish for casting, which has a bad influence on the quality of the cast product and must be removed. The frequency of such waste is carried out every 4 to 6 charges during continuous casting of the same steel type, and each time during continuous casting of different steel types. Then, the inner wall of the tundish from which the residue has been discharged is cleaned, the board or refractory is replaced on the inner wall as necessary, spraying is performed, and a heating process such as gas heating is performed on a standby tundish car. And ready for retreat at the next casting.

[0003] As a conventional waste disposal apparatus, for example, Japanese Patent Laid-Open No.
There is an apparatus described in 155551. In this conventional example, as shown in FIG. 4, a pit 102 is provided below the tundish 1, and a frame 103 is provided in the pit 102.
The lifting frame 105 is raised and lowered by a winch 106, and a slag pot 108 is supported by a traversing carriage 107 mounted on the lifting frame 105. Then, the slag is poured from the tundish 1 into the slag pot 108 in a state where the elevating frame 105 on which the slag pot 108 is mounted is raised to almost the same height as the work floor 104, and the winch 106 is operated to lower the elevating frame 105. Then, the slag pot 108 is transferred to the transport trolley 110 waiting at the bottom of the pit 102, and the transport trolley 110 carries the slag pot 108 to the waste disposal position, where the waste disposal is performed. According to this conventional apparatus, when the residual steel from the tundish 1 is discharged to the slag pot 108, the slag pot 108 rises to near the tundish 1,
It has the advantage that much splash, dust and the like are not generated at the time of discharge.

[0004]

However, in the conventional apparatus, after the residual steel is discharged from the tundish into the slag pot 108, the lifting frame 105 is lowered, and
0, reloading of the slag pot 108, unloading by the transport trolley 110, processing of the remaining steel at the remaining steel processing plant, reloading to the pit 102, reloading of the slag pot 108 to the lifting frame 105, raising of the lifting frame 105, Completes one cycle. Then, the above-mentioned transport trolley 1
While the slag pot 108 is mounted on the slag 10, the slag cannot be discharged from the tundish 1. Therefore, if the time of the cycle of discharging the remaining steel from the tundish 1 is shorter than the time of the one cycle, there is a problem that the work efficiency is hindered, such as a time waiting for the waste. Further, as equipment, the shape of the slag pot 108 is various.
For example, there is a difference between a new one and an old one, a difference in a metal to be treated, a difference in handling residual steel, a difference in handling molten steel in the tundish 1 due to a trouble during casting, and the like. However, the conventional apparatus has a problem that only a certain type of slag pot can be handled.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a slag discharging apparatus which can safely discharge slag, can cope with a fast discharging pitch, and is not restricted by the shape of the slag pot.

[0006]

A reversing drive device, a revolving wheel that reciprocates between a revolving position below the elevating guide, and a residual steel processing plant, and slag that is mounted on the slag wheel and is discharged from the discharging pot. And a slag pot.

[0007]

According to the present invention, at the discharge position where the lifting frame is raised to the upper end position of the lifting guide, the waste discharged from the tundish is received by the discharging pot, and then the lifting frame is lowered, and the lower end position of the lifting guide is changed. Invert the slag pot at the slag position and transfer the slag to the slag pot. Next, the tailings wheel is moved to the residual steel processing plant to process the residual steel in the tailings pot. While the scrap wheel is moving, the lifting frame equipped with the waste pot rises to the waste position and prepares for the next waste. In the present invention, since the waste from the tundish to the waste pot is performed at the position where the waste pot is raised, the generation of splash and dust is small, and the discharge from the waste pot to the waste pot is at the lowered position. It is safe and secure. In addition, the lifting frame with the tailing pot and the rolling wheel with the tailing pot move independently, and the lifting frame is raised while the tailing car is out to the residual steel processing plant, and the draining pot is raised. Can be made to stand by at the tailing position, so that even if the tailing pitch becomes faster, it can be handled. Furthermore, since the discharge from the discharge pot is possible even if the shape of the recycle pan is various, the apparatus of the present invention can be applied regardless of the shape of the recycle pan of the recycle wheel.
