８の直径は0.2〜0.8mm程度が適当である。 DESCRIPTION OF THE PREFERRED EMBODIMENTS A molten metal injection device of a conventional metal sheet manufacturing device will be explained using FIGS. 1 to 3. 1st
The figure is a schematic configuration diagram of a metal sheet manufacturing device, FIG. 2 is a sectional view along the nozzle gap direction of the molten metal injection device, and FIG. 3 is a sectional view along the longitudinal direction of the nozzle. Nozzle for sheeting, 3
4 is a crucible for melting metal, and 4 is a pressurizing port. When the metal to be made into a sheet is sufficiently melted, open the pressurizing port 4.
The molten metal 2 is passed through a filter 5 by applying more pressure and injected from the tip of the nozzle 1, and the molten metal 2 formed into a sheet is rapidly cooled by a cooling metal roll 6 to create a metal sheet. 7 is a pressurizing heater, and if the heating temperature exceeds 1000°C, a silicon knit or induction heating method is suitable. Suitable materials for the nozzle 1 and crucible 3 include quartz, alumina, silicon nitride, etc., and materials that have poor wettability with the molten metal 2 are suitable for the filter 5. Also, the gap d at the tip of the nozzle 1 is 0.2~
The diameter of the hole 8 of the filter 5 is suitably about 0.8 mm, and the diameter of the hole 8 of the filter 5 is suitably about 0.2 to 0.8 mm.

１では１種類のシート幅の金属シートしか製造で
きず、シート幅を変える場合はノズル１の取替え
が必要であつた。 In such a conventional device, when the sheet width becomes wide, the flow resistance becomes uneven due to clogging of the filter 5, etc., and the amount of molten metal 2 injected from the nozzle 1 becomes uneven in the longitudinal direction of the nozzle 1. As a result, the sheet thickness of the manufactured metal sheet becomes non-uniform, and furthermore, the sheet width of the metal sheet sometimes becomes non-uniform. Furthermore, one type of nozzle 1 can only produce a metal sheet with one type of sheet width, and when changing the sheet width, the nozzle 1 must be replaced.

An example of this will be described below with reference to the drawings.

成するのが好ましい。 FIG. 4 is a sectional view along the longitudinal direction of the nozzle of the molten metal injection device in one embodiment of the present invention,
Components that are the same as those shown in FIGS. 1 to 3 are given the same reference numerals, and their explanations will be omitted. 9
1 is an outer wall of a melt injection section 10 which integrally constitutes a nozzle 1 and a crucible 3 in a conventional device, and a nozzle section 11 is formed at the lower end. This outer wall 9
The same materials as those for the nozzle 1 and the crucible 3 are suitable. Reference numeral 12 denotes partition plates installed in the melt injection section 10 at appropriate intervals in the longitudinal direction of the nozzle section 11;
2, the nozzle portion 11 is divided into a plurality of small chambers 13 lined up along the longitudinal direction. Each of these small rooms 13
A filter 5 is installed in the lower part of the filter 5, and a pressurizing port 4 is formed in the upper end. Therefore, it is possible to apply different pressures P 1 ,...P 4 to each small chamber 13 independently. The partition plate 12 is preferably made of the same material as the outer wall 9.
次に上記構成における作用を説明する。シート

各小室１３の溶融金属２に圧力を加えてフイルタ
ー５を通過させ、ノズル部１１の先端から溶融金
属２を射出する。 Next, the operation of the above configuration will be explained. When the metal to be formed into a sheet is sufficiently melted, pressure is applied to the molten metal 2 in each small chamber 13 from the pressurizing port 4 to cause it to pass through the filter 5, and the molten metal 2 is injected from the tip of the nozzle portion 11.
上記構成の溶融金属射出装置を備えた金属シー

P3を他の部分よりも高くすることにより同様にシ
ート厚を修正することができる。 When manufacturing a metal sheet using a metal sheet manufacturing device equipped with a molten metal injection device configured as described above, if the sheet thickness at both ends in the width direction of the metal sheet becomes thinner, the pressures P 1 and P 4 are set higher than in other parts. By doing this, the sheet thickness can be corrected by increasing the molten metal 2 supply amount at both ends, and conversely, if the sheet thickness at the center becomes thinner, the pressure P 2 ,
The sheet thickness can be similarly modified by making P 3 higher than other parts.
またいずれかの小室１３のフイルター５が目詰

３の圧力を一時的に高くすることによつて溶融金
属２の流出量を増加させることができる。 In addition, if the filter 5 of any of the small chambers 13 is clogged and the flow of molten metal 2 is poor, the filter 5 of that small chamber 1
By temporarily increasing the pressure 3, the amount of molten metal 2 flowing out can be increased.

るのが好ましい。 Further, when manufacturing metal sheets of various sheet widths, the sheet width can be adjusted by reducing the pressure in the appropriate small chamber 13 to zero by operating a pressure switch (not shown) according to the sheet width. For example, if a metal sheet with a sheet width W is required, the pressure P 2 ,
P 3 and P 4 are set to zero, and when a metal sheet with a sheet width of 2W is required, the pressures P 3 and P 4 are set to zero. Partition plate 12
The interval W can be arbitrarily set depending on the desired sheet width, so by determining the required sheet width in advance, metal sheets with a plurality of types of desired sheet widths can be obtained. In addition, when changing the sheet width in this way, it is preferable that the distance from the lower end of the partition plate 12 to the nozzle portion 11 be approximately 5 mm or less.

Moreover, metal sheets of various sheet widths can be obtained continuously.
