Abstract
Drawbacks of the technology for flux-cored wire submerged-arc surfacing of metallurgical equipment parts operating under thermal loading conditions are noted. Non-uniform distribution of alloying elements across the deposited bead section leads to decrease in strength of the roll-type continuous casting machines. Peculiarities of heat input in plasma-MlG surfacing provide uniform distribution of the surfacing alloy components in the first layer.
Keywords: arc surfacing, plasma-MIG surfacing, repair technology, metallurgical equipment, heat input, thermal cycle, element distribution
