Abstract
PWI in collaboration with Novo-Kramatorsk Machine-Building Works (NKMZ company) continues improving electroslag welding technology. This work provides a description of the technology of consumable-nozzle electroslag welding in manufacture of large-sized beds with butts of 420-460 Ф 2200-2380 and 940-1120 Ф 1040-1250 mm cross-section. Machine time shortening almost 2 times was achieved. Welded joints of large-sized cast-welded billets of beds for high-capacity mills are characterized by high quality. 8 Ref., 5 Figures.
 
Keywords: electroslag welding, consumable nozzle, large-sized beds, heating, intermediate tempering, machine time reduction
