METALLURGICAL USES FLUXES FOR METALLURGY

scale, precipitator dust, recycled slag, and fine fluorspar have been used as an addition to the steelmaking process to form a fluid slag. Some flux materials are added to repair smelting and refining vessel refractory linings. The selection of the flux to be added depends on the type of process and type of refractory. In the basic

OK Flux 10

The excellent slag removal in narrow V-joints allows the included angle of the joint to be reduced. OK Flux 10.72 can be applied for unlimited plate thicknesses. In wind tower production, plate thicknesses of 50 mm and above are common, generally welded with Y-joints. It is essential that the slag is easily removable on the first run.

A Complete Guide on Flux Cored Arc Welding (FCAW) | NEIT

 · Slag inclusions can prevent the weld''s full penetration due to an incorrect travel speed, heat input, or travel angle. Always clean your weld work between passes and maintain appropriate heat input and travel techniques. When the gas from the heated-up flux-cored wire electrode gets stuck in the metal, it can lead to porosity.

What Is Slag in Welding?

 · The primary purpose of the flux layer is to generate a molten slag that can flow freely over the molten weld pool and cover it evenly. This is necessary to keep the molten weld pool safe from oxidation by atmospheric gases and contaminants. The slag layer also influences other characteristics of the consumable electrode.
