WELDING FLUX GRANULATION METHOD Russian patent published in 2022 - IPC B23K35/40 B01J2/02 

FIELD: metallurgy.

SUBSTANCE: invention can be used in the production of granular fluxes for welding and surfacing of steels and alloys, in particular for welding carbon, alloy steels and alloys. The mixture of mineral raw materials for granulation can be both rocks and screenings of mining enterprises, as well as petrurgical raw materials, slags, ground to 0.25 mm. From the charge hopper 1, the ground raw material enters the charge flow control nozzle 2, which forms a stream of falling particles 4 in the granulation chamber 3, falling into a plasma arc 5 formed by a plasma torch 6, which operates from a power source 8 and a plasma gas 9 Granules in the molten state 12 fall on an inclined box for cooling and supplying granules and charge to the screening zone 11, where welding flux granules 16 are formed, entering the vibrating stand for screening granules and charge 10. Particles with a fractional composition of less than 0.25 mm come back into the batch hopper 1.

EFFECT: improving the manufacturability and productivity of the method for granulation of the fused welding flux, which has a high alloying ability.
