Abstract

Method and heat treatment apparatus in zones, applicable to an article of zirconium alloy, elongated shape, to improve the corrosión resistance produced by the coolant in boiling water reactors, axially moving the article sequentially in areas of maximum critical temperature and with a time and a critical temperature reduction speed, said method being characterized in that it includes the operations consisting in axially moving the article so that it penetrates an electric induction solenoid, traverses it and leaves it, and then penetrates into a cooling station separated from the solenoid and out of it, detecting the temperature of successive longitudinal portions of the article inside the solenoid, and regulating the amount of electrical energy applied to the solenoid so that each successive portion thereof reaches the maximum temperature included between 825ºc and 1,100ºc, while this p orion moves through the space formed between the solenoid and the cooling station.
