METHOD FOR THE PRODUCTION OF A SEMI-FINISHED PRODUCT MADE OF ZIRCONIUM ALLOY FOR THE PRODUCTION OF A FLAT PRODUCT AND USE THEREOF

摘要

A large-sized ingot (1) is produced by smelting the zirconium alloy and the ingot is subsequently forged in order to obtain a semi-finished product (8). The semi-finished product (8), which can be a slab for the production of a flat product, is produced from said large-sized smelted ingot (1) in a single forging operation (7) at a temperature at which the zirconium alloy is in a state that includes both alpha and beta crystalline phases of said alloy.
