METHOD FOR SUPPRESSING PRECIPITATION OF COMPOUND IN MOLTEN METAL

摘要

PROBLEM TO BE SOLVED: To provide a method for realizing the suppression of precipitation of compounds in molten metal by a simple method. SOLUTION: Molten metal substantially consisting of the three components of Sn, Zn and Ti, and in which Ti in the ratio of, by weight, 0.001 to 0.2% to the total content and Zn in the ratio of 8 to 10% to the total content of Sn and Zn are contained is held at a temperature higher than the liquidus temperature as a limit temperature in which a ZnTi based compound in the molten metal and a liquid phase are coexistent.
