Abstract
Electrophysical and thermal peculiarities of electroslag hardfacing (ESH), using an additional hollow graphite electrode, are considered. It is shown that addition of a nonconsumable electrode to the slag pool leads to formation of a high-temperature region in it, which allows a uniform melting of different components of hardfacing consumables. Use of ESH enables producing a heat-resistant deposited alloy based on nickel aluminide.
Keywords: electroslag hardfacing, sectioned mould, composite rod, simulation of ESH process, hollow graphite electrode, current distribution, heat balance, nickel aluminide
