DESCRIPTION OF THE PREFERRED EMBODIMENTS The continuous transportation and treatment apparatus for high-temperature molten material of the present invention will be described below with reference to the accompanying drawings.

[0013] There are various types of high-temperature melting materials such as calcium carbide and ferroalloy, but here, calcium carbide (hereinafter referred to as carbide) will be explained as an example.

FIG. 6 schematically shows the entire continuous conveyance processing apparatus 10 for high-temperature molten material according to the present invention. Device 1 shown in this figure
0 receives carbide from an electric furnace 11 as a source of high-temperature melt, and a plurality of containers 1 (Fig. 1
, see FIG. 2), a mounting table device 2 for placing and transporting each of these containers 1, and a chain cover 2c that connects the mounting table device 2 on which each container 1 is placed in series. The mounting table device 2 is composed of a drive device 13 for moving the loaded mounting table device 2 on a track 4 which is a transport route for carbide, and an anchor chain 5 driven along the track 4 by the drive device 13. In this device 10, carbide is melted and reacted at a temperature of several thousand degrees in an electric furnace 11, and then continuously poured into a container from the outlet (not shown) of the electric furnace 11 and cooled from the molten state. After being transported to a cooling chamber (not shown) provided as necessary for solidification and cooling, the container 1 was tilted at a predetermined section 14 of the track, and the cooled carbide was placed along the track. It is discharged to a crushing process 15 consisting of a hopper, a conveyor, etc., and is classified into a desired particle size and manufactured into a product.

FIG. 1 is an overall perspective view of the container 1.
A protrusion 1a having a predetermined curvature at the front end, a recess 1b having a curvature approximately equal to the curvature of the protrusion 1a at the rear end, a tilting wheel 6 rotatably provided on the right side, and a tilting wheel 6 on the left side. It is a box body consisting of a hinge part 7 provided with a hole 7a, and as shown in FIG. A plurality of them are arranged in series with a gap 1c between them, and hingedly connected to each receiving frame 2, which will be described later. Note that the curvature of the container 1 is the radius of the curved part of the orbit,
It can be determined from the pitch of the wheels 3 of the mounting table device 2, the track width, etc., which will be described later. Furthermore, the size and depth of container 1 are
It can be determined based on the amount of carbide received, cooling time, etc. In order to speed up cooling on a limited orbit, it is best to receive it thinly in a container. Therefore, although a conventional deep-bottomed container can be used, a shallow-bottomed container in which the carbide is cooled quickly and can be easily drained is preferably used. In this case, the thickness of the container received is preferably 20 cm or less; if the thickness exceeds 20 cm, the cooling time will be longer and the cooling will not be completed in orbit. Since there is a certain relationship between the thickness of carbide and the cooling time, it is sufficient to adjust the thickness to 10 to 15 cm in order to cool the carbide in about one hour on a limited orbit, and the amount of outflow of carbide The moving speed of the container can be adjusted accordingly.

As shown in the figure, the container 1 is moved in the direction of arrow B via the receiving frame 2 by the anchor chain 5, and the tilting wheel 6 provided on the right side of the container 1 is moved in the predetermined section 14 (see FIG. 5).
), it moves along the inclined track 9 provided above the track 4, so it floats above the receiving frame 2, but the hinge part 7 provided on the left side of the container is hingedly connected to the receiving frame 2. Therefore, the container 1 tilts around the hinge portion 7. At this time container 1
The carbide 12 inside is discharged and conveyed to the next process, a crushing process, by a conveyor 16 provided along a track 4 with a predetermined section of 14 circles. Thereafter, the container 1 returns to the horizontal state along the inclined track 9 and is transported again to receive the carbide from the electric furnace 11.

Effects of the Invention The apparatus and method for continuously conveying and treating high-temperature molten material of the present invention has a container that receives and houses the high-temperature molten material, and has a protrusion having a predetermined curvature at one end. It has a recessed part that almost matches the curvature, and when two or more containers are connected in series, it maintains a gap that is almost equal to the gap between the containers that occurs when moving on a linear trajectory. Since it can move on a shaped track, it can not only operate safely, but also prevent high-temperature molten material from falling through gaps. Furthermore, since the high-temperature molten material does not fall, it is possible to prevent the driving device and the like located below the container from being melted and damaged.

Furthermore, in the present invention, by providing a tilting means in a predetermined section of the track, the conventionally required crane operation can be omitted, and the high-temperature molten material can be automatically and continuously discharged.
