まう欠点もあった。(Prior art) Raw materials cut out from a hopper using a conventional metal melting and casting device are weighed and divided into many pieces, and the divided pieces are successively conveyed onto a belt conveyor ω as shown in Fig. 27. The conveyor ω is moved in the direction of the arrow, and the above-mentioned large number of small portions are the waste raw materials 61.61...
In the case where the raw materials are continuously fed as they are to the melting crucible in the melting chamber, the size of the raw material particles and Due to imbalances in the ratio of alloy components, and due to vibrations during the movement of the belt conveyor, the raw materials 61, 61..., which have been broken down into smaller portions, move with respect to each other, and in some areas there are piles. There is a drawback that the mountain may become small in some areas due to large wrinkles. When such a material is continuously fed into the melting chamber, the content of the raw material fed at the beginning and the content of the raw material fed later may change, as indicated by the two-dot chain line in the diagram. As shown, there is a problem in that the amount of raw material fed into the melting chamber fluctuates randomly over time. Such a large fluctuation causes irregularities in the melting of the raw materials in the melting chamber, which has the disadvantage that the ingot obtained by solidifying the melted raw materials becomes coarse and dense. In addition, when trying to manufacture alloy ingots, if the raw materials separated as described above are mixed with each other on the conveyor, unevenness will occur in the mixing ratio of the raw materials at different places, and as a result, it will be difficult to The ingot obtained by melting and solidifying also had the disadvantage of segregation of components.

is supported by A backing plate is provided around the periphery of the cylindrical member, and a support roller 47 is in contact with the backing plate. In the above-mentioned cylindrical body material, an inner flange-like flange is provided on the side of the charging port of the casing, and the inner side of the flange serves as a raw material receiving port (2). On the other hand, the other end of the cylindrical body is open and serves as a raw material delivery port 51. A partition wall 52 is spirally attached to the inner surface of the peripheral wall of the cylindrical body material, and a spiral raw material passage along the inner surface of the cylindrical body material is formed at the opening of the adjacent partition wall 52. ing. The partition wall 52 has, for example, 13 pitches. The number of pitches is sufficient as long as the number of pitches is such that one section of the raw material introduced from the receiving port can be sufficiently mixed while reaching the outlet port 51 through the raw material passage 53 due to the rotation of the cylindrical body material. 1
It may be less than 3. In addition, the height of the partition wall 52 is preferably set to such a height that the raw materials in each section placed in the raw material passageway will not cross over the wall 52 and transfer to other sections, and its dimensions should be set to the height of each section. It should be determined depending on the amount of raw materials, the diameter of the cylindrical material, etc. For example, if the diameter of the cylindrical material is about 1100 fl, the raw material of the section is about 20 kq, and the size of one pitch is 225 M, the height of the inner wall 52 is, for example, about 300 ff. With this size, it is possible to smoothly transport up to a single piece of 80JEI cubic thickness. In this example, the trench-like cylindrical body is arranged substantially horizontally, but it may be tilted within a range of up to about 5° so that the side facing the outlet 51 is higher.

Charge. Next, cylindrical body disease is 860
The first section of raw material is moved one pitch forward toward the outlet 51 along the passage &. Then, in this state, the bucket conveyor is again driven for one packet in the same manner as above, and the entire amount of raw material for the next section is charged. Thereafter, in the same manner, while repeating the forward movement of the raw material in increments of -pitch, the divided raw materials are charged one after another by the number of pitches of the compartment walls.

In these figures, (8) shows the state of the cylindrical body disease seen from the side of the outlet 51, and 03) shows the state in which the cylindrical body disease in each state is cut at its uppermost position and expanded. It shows. The amount of each divided raw material put into the raw material passage 53 is lifted up by the inner wall surface of the cylindrical body and moved upward by the rotation as shown by the arrow of the cylindrical body. repeats falling downwards. By repeating this process, the raw materials in each segment sequentially move toward the outlet 51 along the spiral raw material passage group.

れる状態を経て第に図に示される状態となる。When each divided raw material group moves to the delivery port 51 due to the rotation of the cylindrical body as described above, the end 52a of the partition wall 52 passes through the lowest position as shown in Fig. At a certain point in time or before or after that point, the separated raw materials begin to fall from the outlet 51, and the tubular body rotates approximately 90 degrees from the state shown in Fig. 7, that is, the state shown in Fig. S in the trench. During this time, most of the -2 classified raw material falls from the outlet 51. and the sixth
As shown in the figure, the cylindrical body disease is approximately 18 mm from the state shown in Figure 1.
At the time of rotation by 0 degrees, almost all of the raw material classified into the above-mentioned - category falls from the delivery port 51. Thereafter, the state shown in FIG. 7 is passed through to the state shown in FIG.

鋳塊においても大きな粗密ができる様なことはない。That is, the state is similar to that shown in FIG. q above, and the delivery of the next classified raw material is started. By repeating such operations one after another, the raw materials are sequentially supplied from the outlet 51 to the melting chamber without mixing with each other. If this situation is shown in a graph, the solid line in Fig. 7 shows a situation similar to a water explosion. That is, as time passes, a fixed amount of raw material is delivered at fixed intervals. As a result, in the melting chamber, the amount of raw material supplied does not change between the beginning and the end of melting, so that the amount of raw material is less likely to be too much or too little. Therefore, there is no possibility that the ingot obtained in the casting apparatus C will have large density differences.

粗密をよシ小さくすることができる。In the above case, if the cylindrical body is tilted so that the side of the outlet 51 is higher, the delivery of one section of raw material from the outlet 51 due to the rotation of the cylindrical body is reduced. It can be performed little by little over a relatively long period of time during one rotation of the disease. As a result, fluctuations in the amount of raw material in the melting chamber can be made smaller, and the density of the ingot can be further reduced.

に形成される。Next, FIGS. 70 to 11 show examples of different placement states of partition walls. In the example shown here, the progression of the spiral of the partition wall 52e is slightly increased in the vicinity of the raw material outlet 516, so that the width of the raw material passage 53e gradually becomes wider in the vicinity of the raw material outlet 51e. By gradually increasing the width of the raw material passage 53e in this way, it is possible to prevent the raw material layer from suddenly collapsing due to the rotation of the cylindrical body near the raw material delivery port. As,
- The raw material 556 of the section can be continuously delivered in small portions over one revolution of the tube 44e, and this can be continued over a large number of raw materials. Rather, as shown in FIG. 75, the raw material can be supplied to the melting chamber in a constant amount at normal pressure over time. As a result, the amount of raw material supplied to the melting chamber is always constant, and the ingot produced in the casting device is formed to have uniform density throughout.

In addition, the section W in which the helical advance of the partition wall 526 is increased is, for example, a range corresponding to one-quarter rotation of the cylindrical body 44e, and the degree of helical advance of the partition wall 52e at that point is is set to be about twice as large as in other locations. However, the degree of increasing the progress of the spiral in the above range W or at that location is -
It is preferable to determine it experimentally depending on the amount of raw material in the section, the dimensions of the cylindrical body 44e, the height and pitch of the partition wall 52e, the rotational speed of the cylindrical body 44e, and the like. That is, as described above, the cylindrical body 44
It is preferable to set the condition so that one section of the raw material is continuously sent out little by little from the delivery port 51e over the entire process of one rotation of e.

(The same idea will be used in the next edition as well, and the letters f, g, and h will be added in order to omit redundant explanations.) Next, Figures 1-2 to 1-g show the cylindrical shape near the outlet. An example is shown in which the shape of the body is different from that described above so that the width of the material passage therein is increased. That is, at the end 52af of the partition wall 52f, the cylindrical body 44f
It is formed to have a slightly longer length, and is provided with a protruding part secretion that further protrudes from the end part 52af. By doing so, the raw material can be continuously delivered little by little over the entire process of one rotation of the cylindrical body 44f, as in the previous embodiment.

The range W' in which the height of g is successively lowered is determined, for example, in the range of 180 degrees to 270 degrees. However, as mentioned above, it is best to determine the degree and range of successive reductions in the height of the partition wall, as in the case described above, for example, as shown in Figure 1 (5).

ろる。(Effects of the Invention) As described above, in the present invention, the raw material is weighed into small portions using a measuring cutter, and the weighed raw material 5 is divided into small portions. The structure is such that the raw material is fed into the cylindrical body and directed to the melting chamber through a spiral passage provided on the inner peripheral wall of the cylindrical body. The material of one section that has entered the tube does not mix with the other materials of the other sections, and in the cylindrical body 44, the material advances in a vertical direction in the U direction. This means that the raw material properties (mixing ratio of multiple raw materials) of each raw material are not mixed with other raw materials to change the raw material properties, and the raw materials can be directly delivered to the melting chamber, where they can be of high quality. The effect of creating molten metal is great.
