Production of carbide laden consumables in a graphite mold

摘要

A carbide laden consumable is produced using a mold having at least one U-shaped groove running along the surface thereof, the consumable being produced by charging a first layer of a powdered self-fluxing alloy into the groove, a second layer of a powdered refractory carbide on said first layer and a third layer of said self-fluxing alloy on the carbide layer, and the charged mold then passed through a heating furnace under a reducing atmosphere to produce by melting and cooling a consumable of markedly improved quality.
