MANUFACTURING METHOD OF SEAMLESS HOT-ROLLED TUBES ON PIPE ROLLING UNITS WITH PILGER MILLS FOR STEAM BOILERS, STEAM LINES AND HEADERS OF UNITS WITH HIGH AND SUPERCRITICAL STEAM PARAMETERS

FIELD: metallurgy.SUBSTANCE: hollow electroslag remelting cakes are heated to ductility temperature and rolled on a pilger mill. Rolling is performed in rolls with a body diameter of 1150 mm so that tubes with dimensions of 610×32-90 or 630×28-80 mm are obtained. Difference between inner diameter of...
