CONTINUOUS CASTING METHOD AND CONTINUOUS CASTING DEVICE FOR TITANIUM INGOTS AND TITANIUM ALLOY INGOTS

摘要

The continuous casting device according to the present invention enables at least some of a plurality of hearths (3) to be converted between being hearths (13) used for titanium, which are used during the continuous casting of titanium ingots, and being hearths (23) used for titanium alloy, which are used during the continuous casting of titanium alloy ingots. The number of hearths (23) used for titanium alloy is greater than the number of hearths (13) used for titanium. Also, the total capacity of the hearths (23) used for titanium alloy is greater than the total capacity of the hearths (13) used for titanium. Thus, titanium ingots and titanium alloy ingots can each be continuously cast by means of a single piece of equipment.

主权项

1. A continuous casting device for titanium ingot and titanium alloy ingot that injects a molten metal having titanium or a titanium alloy melted therein into a bottomless mold via a plurality of hearths and while solidifying the molten metal, withdraws the resulting ingot downward, and thereby produces an ingot made of the titanium or titanium alloy by continuous casting,
wherein as at least some of the hearths, hearths for titanium to be used at the time of continuous casting for titanium ingot and hearths for titanium alloy to be used at the time of continuous casting for titanium alloy ingot can be used exchangeably, the number of the hearths for titanium alloy is greater than the number of the hearths for titanium, and the total capacity of the hearths for titanium alloy is greater than the total capacity of the hearths for titanium.
