JPS62256978A - Continuous production of metallic anode - Google Patents

Abstract

PURPOSE:To easily and continuously produce metallic anodes by cutting a flat metallic plate with at least one water jet cutter. CONSTITUTION:A flat plate 6 having holes is drawn out of a casting machine and passed by a water jet cutter 8. The cutter 8 cuts the parts 2, 4 to be cut at first and then cuts the next parts 1, 3 to be cut. Water jets are ejected under >=2,500kg/cm<2> pressure at about 19l/min rate. The diameter of the water nozzles is regulated to about 0.6mm and metallic oxide powder is added on the upstream side of the nozzles.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for continuously manufacturing metal anodes. Especially by cutting with water jets.

This is a method of obtaining a metal anode.

There are various continuous manufacturing methods by cutting Rieger metal anodes, for example, Japanese Patent Application Laid-Open No. 54-81104.

The above method uses a plasma torch to cut, and it is difficult to cut unless it is at a high temperature of 800°C or higher.In the case of blister copper, it is necessary to moisturize the blister copper plate after casting, making the process complicated. there were.

Furthermore, since cutting is done by fusing, the temperature is high, and the blister copper is fused and cut to a length of about 7 mm, which is not desirable, and it also produces many pieces of light, copper fume, etc., which is not desirable.

Furthermore, there were problems such as some unevenness and burrs on the cut surface, and high cutting costs.

The present inventors made the following invention as a result of intensive studies to solve the above-mentioned drawbacks.

The present invention relates to a method for continuously manufacturing metal anodes, which comprises cutting a flat metal plate using at least one water jet cutting machine.

Furthermore, as an embodiment, two water jets are used.
The present invention relates to a continuous manufacturing method for metal anodes, characterized by spraying and cutting at a discharge pressure of 500 kg/ad or more.

The metals used in the present invention include ffl copper, crude lead, etc.
It is a metal that requires electrolytic refining.

Casting is performed using, for example, a rotary caster or a partially modified U-making machine.

The resulting continuous flat plate is then cut to obtain, for example, what is shown in FIG. 1 or FIG. 2.

In the case of Figure 1, the casting machine (7
) is cut by a cutting machine (8).

After cutting (2, 4) in Fig. 1 at the same time, (1
, 3) are cut.

Cutting is done with a water jet, and the discharge pressure is 2
It is 500 kg/aJ or more.

The water jet is used by containing metal oxide powder or the like in order to enhance its cutting ability.

The tip diameter of the water nozzle is preferably 0.3 to 0.9n.
It is n+ψ.

The amount of water discharged is 6 to 12 Q/min per nozzle. It is preferable that the water be recycled and used after separating and recovering the metal oxide powder and the like.

The distance between the nozzle and the target object is approximately 1 to 6 m.

The thickness of the target object is usually about 15 to G0nn.

By implementing the present invention as described above, the following effects can be obtained.

Yuri Gomenmai (1) Since it is cut with water jet 1~, it is possible to cut it at room temperature.

(2) There is no cracking in the thickness direction due to cutting, and no unevenness on the cut surface.

(3) There is no generation of light or metal fume NOx, and the work can be carried out in a favorable working environment.

(4) There is no reason to cut it, just like plasma cutting.
m or less, preferable cutting is possible. This will effectively increase the anode production per ribbing machine.

Referring to Figure 1 above, we will explain the continuous construction of blister copper anodes.

The casting machine used was a modified rotary caster equipped with a core (5).

As shown in Figure 3, the perforated flat plate (
6) passes through a water jet cutting machine (8).

For cutting, cut the cutting part (2.4) in Figure 1,
Next, (1.3), which is the rear part of the progress, is cut.

The discharge pressure of the water jet was 3000 kg/d, and the discharge water was discharged at 9 Q,/min.

The diameter of the water nozzle was 0.6 Iφ, and cutting was performed by impregnating metal oxide powder on the upstream side from the water nozzle discharge side.

The distance between the nozzle and the flat metal plate was 3 m.

Cutting was carried out to produce the blister copper anode shown in Figure 2.

The casting machine used rotary casters to produce a continuous flat plate of blister copper.

The flat plate that came out of the casting machine was cut along line (10) as shown in FIG.

In addition, the water jet 1 was used for cutting, but the line (10
) was installed with a water jet that moved at the same speed as the board, and a device was used that memorized the cutting trajectory.

The cutting device has a discharge pressure of 3000 kg/an and a discharge amount of 95Q.
/min, nozzle O, Grrmφ, 10 nozzles 2
The foundation was established.
