Latest Patents

Katsuyuki Takezaki holds a patent for a method of manufacturing zinc alloy ingot. This method involves a molten zinc alloy containing 4–22 mass % aluminum, 1–7 mass % magnesium, and optionally small ratios of titanium, boron, and silicon. The process requires holding the molten alloy at a temperature higher than the solidification-beginning temperature plus 85°C for homogenization. Afterward, it is cooled to a temperature equal to the solidification-beginning temperature plus 20–65°C. The molten alloy is then poured into a mold, where it naturally cools and solidifies into an ingot, ensuring that the upper part is heated. Once the upper surface begins to solidify, it can be optionally cooled with water. This innovative method results in an ingot structure that is free from cracks or cavities, making it suitable for replenishment in a molten pool.
