Abstract

Спосіб рафінування сталі від водню при електрошлаковому зварюванні, який полягає в створенні захисної атмосфери "подушкою" терморозширеного фториду графіту над розплавом шлаку, розкисленні поверхні шлаку вуглецевими матеріалами (розкислювач - фторид графіту), і додатковому введенні в шлакову ванну окислювача - оксиду заліза, у вигляді шматків порошкової стрічки, в осерді якої міститься оксид заліза і 1-2 % фториду графіту, причому над розплавом шлаку розміщується спеціальна графітова екрануюча пластина П-подібної форми, щільність якої менше щільності розплавленого шлаку.The method of refining steel from hydrogen in electroslag welding, which is to create a protective atmosphere "cushion" of thermally expanded graphite fluoride over the slag melt, the deoxidation of the slag surface with carbon materials (deoxidizer - graphite fluoride), and additional introduction into the slag, into the slag pieces of powder tape, in the core of which contains iron oxide and 1-2% of graphite fluoride, and above the melt slag is placed special graphite shielding plate U-shaped, the density of which is nshe density of molten slag.
