本発明は溶融金属供給装置内の溶融金属の保温
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to keeping molten metal warm in a molten metal supply device.
容器に畜積された溶融金属を移動磁界を発生

ため、どうしても上記冷却水の影響が溶融金属ま
で及んでしまうためである。 When molten metal accumulated in a container is supplied to a mold etc. by an electromagnetic pump that generates a moving magnetic field and uses the molten metal that has entered the molten metal hole as a secondary conductor, the amount of molten metal supplied per unit time is When the amount of molten metal is small or when the supply of molten metal is stopped for a long time, the temperature of the molten metal in the introduction hole tends to decrease and the molten metal tends to solidify. The cause of this temperature drop of the molten metal is considered to be as follows. Cooling water is flowing through the electromagnetic pump to cool the coil within the electromagnetic pump. Although this cooling water must not have any effect on the molten metal in the molten metal inlet, the thickness of the tubular refractory that forms the molten metal inlet must be limited from the viewpoint of electromagnetic efficiency. This is because the influence of the cooling water inevitably extends to the molten metal.

品の均一化ができないという欠点があつた。 Therefore, as a means to solve the above problem, conventionally, an electromagnetic pump has been used to direct the thrust of the molten metal in the molten metal introduction hole toward the container in which the molten metal has been accumulated, thereby causing forced circulation in the molten metal. The molten metal, which had been sufficiently warmed by the heating device, was replaced with the molten metal whose temperature had dropped in the molten metal feed hole at appropriate times. However, although the conventional method described above can reduce the temperature difference between the molten metal sent to the mold and the molten metal in the container, it is impossible to avoid a certain degree of temperature drop, and the cast product The disadvantage was that unevenness occurred and the product could not be made uniform.
そこで本発明は容器に蓄積した溶融金属を保温

供給するための溶融金属供給装置を同一保温内に

属をも保温しようとしたものである。 Therefore, the present invention utilizes the above-mentioned heating device by housing a heating device for keeping the molten metal accumulated in the container warm and a molten metal supply device for supplying the molten metal from the container to the mold etc. in the same heat-insulating area. This is an attempt to keep the temperature of the molten metal being fed by the molten metal supply device.
以下図面に基づき本発明の実施例を説明する。

Reference numeral 1 denotes a container made of furnace material, in which molten metal 1a is accumulated, and an outlet 1b for taking out the molten metal 1a on the side of the bottom.

一体として収めてある。 Several heating devices 2 are attached around the outer wall of the container 1 to keep the molten metal 1a inside the container 1 warm. 1c is a lid that prevents the heat from the heating device from escaping from the container. Reference numeral 3 is a tubular refractory having a molten metal guide hole 3a therein, which is a passage for molten metal, and is installed diagonally upward from the outlet 1b, and its upper end is connected to a tap trough 4. Reference numeral 5 denotes an electromagnetic pump, which is molded with a heat insulating refractory material 5a and generates a moving magnetic field.
It is installed at a position where the molten metal entering a can be transported as a secondary conductor. 6 is a thermal container,
It is made of a heat insulating material, and houses the container 1, the heating device 2, the tubular refractory 3, and the electromagnetic pump 5 as one unit.

熱装置２の熱の影響を受けることはない。 In the above configuration, the molten metal 1a in the container 1
is kept warm by a heating device 2. When the electromagnetic pump 5 operates, the molten metal 1a discharged from the outlet 1b by the action of its moving magnetic field passes through the molten metal guide hole 3a, is sent to the tap trough 4, and is tapped into a casting or the like. Here, since the heating device 2 and the tubular refractory 3 are in the same heat insulating container 6, the heat of the heating device is transferred to the tubular refractory 3, and the heat in the heat insulating container 6 is sealed with the lid 1b. Therefore, the tubular refractory 3 is always kept warm. Therefore, the molten metal passing through the inlet hole 3a formed by the tubular refractory 3 can be kept at the same temperature as the molten metal 1a in the container 1 at all times. Further, since the electromagnetic pump 5 is molded with a heat insulating refractory material 5a, it is not affected by the heat of the heating device 2.

製品の均一化が計れる。 As described above, the present invention has a heating device for keeping the molten metal accumulated in the container warm and various devices for supplying the molten metal from the storage container to the mold etc. in the same heat insulating container. Cooling water that uses the heat of the heating device to keep the molten metal warm during the process of transporting it from the storage container to the mold, and cools the coil in the electromagnetic pump that transports the molten metal from the storage container to the mold, etc. It is possible to prevent the temperature of the molten metal from decreasing during the transportation process due to the influence of molten metal, etc., even if the supply of molten metal is stopped for a long time. Therefore, the temperature of the molten metal during the transportation process can be kept constant, and the molten metal will not solidify during the transportation process, and there will be no unevenness in the cast product.
Product uniformity can be measured.
