Powders for flux cored wire that the sulfur-based, flux cored wires and flux cored wire production method of

摘要

Powder which is for a flux-cored wire intended to become alloyed with a molten metal bath and which is formed by particles composed with at least 95% of sulphur, characterised in that its granulometric population is defined by: 1 μmd10340 μm; 200 μm d502000 μm; 500 μm d902900 μm. Sulphur-based flux-cored wire, characterised in that it contains the preceding powder, and in that the compaction rate of the powder within the wire is greater than or equal to 85%. Method for producing a sulphur-based flux-cored wire for alloying with molten metal baths.
