Abstract

PURPOSE:To repeatedly manufacture pouring sprues having a certain shape and arranging intervals by filling a stamping material into a mold for stamping pouring sprues, executing molding to form pouring sprues and attaching the pouring sprues to the pouring side in a measuring flume. CONSTITUTION:A stamping material is filled into a mold for stamping pouring sprues, is subjected to wet stamping, is dried and is released from the mold to form pouring sprues 12. At this time, blocks 14 for forming pouring sprues change their fixed positions to the ones at desired intervals by loosing a nut 15 and sliding the blocks 14 along an oblong hole 13. The formed pouring sprues 12 are set on the pouring side in a measuring flume 5 for casting a copper anode. At the time of changing the dimension and shape of an anode, the fixed positions of blocks for forming pouring sprues are changed in accordance with the dimension and shape of a mold. In this way, the arranging intervals of pouring sprues can easily be changed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for manufacturing a measuring trough for copper anode casting in copper smelting.

(Prior Art) Conventionally, in the casting of copper anodes to be subjected to electrolytic refining in copper smelting, as shown in FIG. It is poured into a reservoir 4 and a measuring bucket 5 through a sweeper 3. The molten copper stored in the measuring tub 5 is poured into a mold 6 moving on a turntable in a fixed amount in a fixed cycle, thereby producing a copper anode of a predetermined shape and weight. When molten copper is poured from the measuring tub 5 into the mold 6, if the shape of the pouring port is not appropriate, molten copper scatters during pouring, resulting in overcasting or bulges at the end of the anode. This state is shown in FIG. 3, which is a cross-sectional perspective view of the mold 6 and the cast copper anode 7, where 8 is a casting and 9 is a bulge. In addition, this cast tension and build-up are closely related to the distance between the pouring port of the measuring tub 5 and the end of the mold 6, and if the pouring port is close to the end of the mold 6, the molten copper may scatter and the pouring may occur during pouring. The effects of the agitation of the hot water tend to appear at the edges of the mold. FIG. 4 schematically shows a state in which the intervals between the pouring ports of the measuring tub 5 are too wide compared to the size of the mold 6.

Conventionally, the measuring bucket 5 was usually replaced every time it was cast, and it was broken and remade by hand, so it was difficult to obtain a measuring bucket that always had a constant shape of pouring spout. In addition, if the dimensions of the electrolytic vessels for electrolytic refining that provide the anodes obtained by casting are different, it will be necessary to cast anodes of different sizes and shapes, but in this case, the spacing of the pouring ports of the metering tank should be adjusted appropriately. It is preferable to change it. However, until now there has been no suitable method for this purpose.

(Problems to be solved by the present invention) The present invention solves the above-mentioned conventional drawbacks,
To provide a means for repeatedly manufacturing a measuring tank having pouring ports at appropriate intervals, and to easily manufacture a measuring tank having pouring ports at appropriate intervals when it becomes necessary to cast anodes of different sizes. The task is to do so.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a frame member formed on a plate material and having an open upper part, and a fixed position inside one longitudinal side surface of the frame member. A pouring spout stamp mold equipped with a plurality of variably provided pouring spout forming blocks,
A method for manufacturing a measuring tank for copper anode casting, characterized in that a stamp material is filled and molded to form a pouring port, and the pouring port is attached to the pouring side of the measuring tank for copper anode casting.

(Function) In the present invention, the pouring port is formed by filling and molding the stamp material into the stamp mold, which is a frame member equipped with a plurality of blocks for forming the pouring port, so the blocks for forming the pouring port are fixed. If you do this, you can repeatedly manufacture pouring spouts of the same shape. In addition, the fixing position of the pouring hole forming block is variable, so when changing the dimensions and shape of the anode, the fixing position of the pouring hole forming block can be changed to match the dimensions and shape of the mold. The arrangement interval can be easily changed.

<Example> An example of the method of manufacturing a measuring tank for copper anode casting according to the method of the present invention will be described with reference to FIG. In FIG. 1a), 10 is a plate material, and 11 is a frame member formed on the plate material 10 in accordance with the shape of the pouring spout 12 to be manufactured. 1
Reference numeral 3 denotes a long hole, which is formed in one longitudinal side surface of the frame member 11.

A plurality of blocks 14 are fixed to the inside of the frame member 11 by naphts 15. This pouring hole forming block 14 can be opened by loosening the nut 15.
3, the fixed position can be changed to a desired interval.

The pouring spout stamp mold configured as described above is filled with SiC-based stamp material mixed with cement or the like as required, and then wet-stamped. The pouring spout 12 after drying and demolding is shown in FIG. 1b) and FIG. 1C>.

Fig. 1 b) shows an example in which the pouring hole forming block 14 is widely arranged and molded to be suitable for casting an anode using a large-sized mold, whereas Fig. 1 C) shows an example of molding using a small-sized mold. An example is shown in which the spout forming blocks 14 are molded with narrow intervals to suit the purpose of the present invention. The pouring port 12 thus formed is set on the pouring side of the measuring tank 5 as shown in FIG. 1d).

In addition, in the above-described embodiment, Si is used as the stamp material.
The reason why a C-based material is used is to prevent molten copper from adhering during casting.

(Effects) The method for manufacturing a measuring tank for copper anode casting according to the present invention has the following effects. That is, it is possible to repeatedly manufacture pouring holes with a constant shape and spacing, and when the mold size and shape are different, pouring holes with different spacing can be easily created. In addition, Si is used as a stamp material.
If C-based material is used, it is possible to prevent molten copper from adhering to the spout. Therefore, it is possible to cast a copper anode without casting or bulges on the peripheral edge, and it is possible to prevent the occurrence of slag and the like during electrolytic refining.
