Abstract
Selection of the electroslag welding process for making vertical butt Joints of the shells of DP-5 blast furnace housing in Enakievo Metallurgical Works is substantiated. Mechanical properties of the Joint metal of 09G2S steel 40–50 mm thick made by electroslag welding with concurrent cooling are given. Technological sequence of assembly and welding with application of site welding equipment AD-381 is described.
Keywords: electroslag welding, blast furnace housing, 09G2S steel, thermal cycle regulation, assembly and welding technology, automatic welding machine
