を目的としている。The hot water stopper holds the molten material in a pouring furnace or other metallurgical vessel by closing the hot water nozzle, and releases the molten material by opening it. Since the hot water rod has a through hole in the center part and the plunger moves up and down or rotates in it, its strength is weaker than that of the solid structure due to its hollow structure, and It is easy to be broken due to thermal shock due to repeated contact of and must be replaced each time. In addition, if there is a poor sealing with the tap nozzle due to wear of the tip, it must be replaced. At this time, the plunger must be removed or replaced. As described above, there is a problem that the line operation time is reduced due to the time required for maintenance, and that the cost of parts such as the replacement of the plunger is increased. INDUSTRIAL APPLICABILITY The present invention can cast a good casting by automatically removing the slag adhering to the tapping nozzle, and is easy to maintain and can be easily repaired. It is intended to provide a cleaning method.

生じるようになる。BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIG. A nozzle 2 having a flow path 5 is attached to the bottom of the pouring container 1. The pouring from the pouring container 1 to the mold (not shown) is performed as follows, for example.
The pouring container 1 is position-controlled in at least one axial direction of the top and bottom and the plane, the bottom surface of the nozzle 2 is in contact with the upper surface of the mold to be poured, and the flow passage 5 and the spout formed on the upper surface of the mold are in communication with each other. When it is positioned as described above, the required amount of molten metal is supplied to the pouring container 1. The molten metal is held in the pouring container 1 and poured into the mold through the nozzle 2. When pouring into the mold is completed, the pouring container 1 moves to the next mold to be poured, and the newly supplied molten metal is poured into the mold in the same manner as above. After that, the same operation is repeated. By the way, when the pouring operation is repeated, the nozzle 2
The slag 10 is formed in the flow path 5 to prevent the flow of the molten metal into the mold, and the pouring speed decreases, causing a problem in casting a good product.

A slag removing device 7 facing from above is provided. The slag removing device 7
An actuator such as an air cylinder 4 and a removal rod 3 that can be moved up and down by the operation of the air cylinder 4 are provided, and can be easily attached and detached by a bolt 6. The outer diameter of the removing rod 3 is smaller than the inner diameter of the flow channel 5, and its lifting stroke is such that the tip can pass the slag attachment position of the flow channel 5 when the removing rod 3 moves up. The pouring container 1 moves above the removing rod 3 by interrupting the pouring operation to the mold every preset number of cycles, that is, every time the series of pouring operations described above are completed, for example, 10 times. , The flow path 5 and the removing rod 3 stop at a position where their axes substantially coincide with each other. Next, the air cylinder 4 is operated and the removing rod 3 is reciprocated in the flow path 5 to remove the attached slag 10.
After this, the pouring container 1 moves again to the next casting target mold, and the pouring operation is reunited.

後には注湯容器１の注湯動作を行うことができる。The air cylinder 4 can change the operating force of the removing rod 3 by adjusting the supply air pressure. Even if the tip of the removing rod 3 comes into contact with the nozzle 2, the nozzle 2 or the removing rod 3 can be changed.
Can be prevented from being damaged. Further, the slag removing device 7 can easily monitor the operating state by detecting a predetermined stroke amount of the removing rod 3. As described above, the detection sensor for this purpose can be attached to a place that is not easily affected by the heat of the molten metal, and has high detection reliability. Further, when a malfunction occurs, the slag removing device 7 is installed apart from the pouring place, and the bolt 6 can be removed to easily replace the spare slag removing device, so stop the casting line. The pouring operation of the pouring container 1 can be performed without or after a short stop.

ル２が除去棒３を貫通するように下降させてもよい。According to the present invention, in addition to the above-mentioned pouring method, the pouring container 1 is provided with a hot-water stop rod for opening and closing the flow path 5 of the nozzle 2.
The pouring to the mold can also be applied to the pouring method performed by the action of the hot water stop rod. If the pouring accuracy of the pouring container 1 is good, the removing rod 3 may be fixed and the pouring container 1 may be lowered so that the nozzle 2 penetrates the removing rod 3.

Can be prevented. As a result, by keeping the inner diameter of the nozzle within an appropriate range, the pouring time can be made almost constant and a good casting can be cast. Also, since the slag removing device is installed separately from the pouring device at a location separate from the pouring place, even if a problem should occur with the slag removing device, replace it without stopping the pouring operation. Can
It helps prevent a drop in the operating rate of the casting line.
