は、エクスＡ？ンド加工方式と打抜加工方式とがある。In recent years, along with the demand for lead-acid battery maintenance and 7-lead batteries, there has also been a demand for higher capacity and longer life in terms of battery performance.
Furthermore, they are trying to reduce the weight of the battery. For this reason, a machining method has been introduced in place of the conventional resurfacing method in the manufacturing method of storage battery grid substrates.The feature of this method is that it is made from lead alloy thin sheets made in advance by various methods. The electrode plate substrate of a desired shape is formed using a machining method. There are two types of processing methods: a bond processing method and a punching method.

注、入し該ロールで冷却して凝固相を形成すると同時に
圧□延して薄板とする直接鋳造圧延方式などがある。The most common method involves solidifying a molten lead alloy on the surface of a water-cooled rotating drum, and then peeling off the solidified layer continuously from the drum surface to form a thin plate. In the direct method or the rolling method in which a lead alloy slab cast into a predetermined shape is rolled into a thin plate, the molten lead alloy is passed through opposing belts, and a An annular belt system in which the sandwiched molten metal is solidified to form a thin plate, or the molten metal is continuously poured into the gap between a pair of rolls, cooled by the rolls to form a solidified phase, and simultaneously rolled to form a thin plate. There are direct casting and rolling methods.

れを防止するために煩雑な装置を必要とする。In addition, several methods have been proposed for the direct L uJ rolling method based on the relative positional relationship of the two rolls. When the angle θ with horizontal lines t and m is 180°,
These rolls 14 and 15 rotate as shown by the arrows, and a molten lead alloy 12 is supplied between the two rolls on the axis, and is cooled by the rolls to form a solidified phase 13.
1. However, in this method, when pouring the molten metal, the molten metal tends to leak to the outside, contaminating the outside and causing loss of the molten metal. Therefore, a complicated device is required to prevent leakage when pouring the molten metal.

When the angle is 180°, the molten lead alloy 22 fed through the nozzle 27 is cooled by the rolls 25, 26 to form a solidified phase 23° 24, which is rolled to form a thin lead alloy sheet. Get 21.

る。In this case, the amount of molten metal is controlled so that the solidified phase 23 formed by cooling on the surface of the upper roll 0 becomes thicker than the solidified phase 24 formed by cooling on the surface of the lower roll O'. However, when rolling a thin lead alloy sheet, the solidification phase 2
4 has a larger amount of deformation than the solidified phase 23, so for metals with relatively low deformation resistance, such as lead alloys, the solidified phase 23 formed in front of the rolls is pushed out to the front even during rolling. This causes a mechanical collision at the tip of the nozzle 27 of the tundish, which displaces the normal position of the nozzle 27 or impedes the normal leakage flow of the molten metal 22.
これを防止するために圧延速度を大きくすることが考え
られるが、大きくすると圧延された鉛合金薄板に歪等の
欠陥を生ずる。In order to prevent this, it is conceivable to increase the rolling speed, but if the rolling speed is increased, defects such as distortion will occur in the rolled lead alloy thin plate.

湯を注入し、鉛または鉛合金の薄板をうるものである。The present invention has been made in view of the above drawbacks.b) A method for producing lead or lead alloy thin sheets of excellent quality has been discovered. That is, in the method of the present invention, lead or lead alloy molten metal is continuously injected horizontally into the gap between a pair of rolls, cooled on the roll surface to form a solidified phase, and at the same time, the solidified phase is rolled to form lead or lead alloy. In a method for continuously manufacturing thin plates, a pair of rolls is set at an acute angle of 45° to 85° between the axis of the rolls and a horizontal plane, and the molten metal is injected from the acute angle side to form lead or lead alloy. It is used to make thin plates.

果ノズルを破壊して製造不可能の原因とな）易い。In the method of the present invention, the angle between the axis of the pair of rolls and the horizontal plane is limited to 45° to 85°, and the reason why the molten metal of lead or lead alloy is poured into the acute angle side is that if the angle is less than 45°, In this case, the thickness and length of the solidified layer 33 formed by cooling on the surface of the upper roll 35 becomes significantly large, and it penetrates into the plane of the nozzle 27, thereby destroying the nozzle. (Cause of unmanufacturability)
又８５°を越えた場合には上ロール３５０表面で冷却さ

となシ、著しい向上はできなくなる。Further, when the angle exceeds 85°, the thickness and length of the solidified layer 33 formed by cooling on the surface of the upper roll 350 gradually decreases.1 Therefore, the 1 production rate remains approximately the same as before, but is significantly improved. will no longer be possible.

Since the solidified phase formed by the upper roll 35 can increase the amount and length of 7 as shown in FIG.
The rolling speed can be increased to 1.3 to 1.4 times the conventional rolling speed without causing any troubles as in the past, and the lead alloy thin plate 31 with excellent quality and sound is continuous in the direction of arrow C. It was possible to manufacture it by doing so.
