Abstract
Mechanical properties of metal of 45 mm thick 06G2B steel welded joint made by high-speed electroslag welding with additional concurrent cooling are presented. Selection of method of electroslag welding for enlargement of blocks and erection of a girth of a non-cooled part of a self-bearing housing in repair of the first stage of blast furnace DP-9 at OJSC "KGMK Krivorozhstal" was substantiated. The process flow diagram using the new machine AD-381 for site electroslag welding is described
Keywords: electroslag welding, housing of blast furnace, machine for site welding, sparsely-alloyed steel 06G2B of increased strength
