FLUX CALCINATION METHOD Russian patent published in 1997 - IPC

Abstract RU 2071896 C1

FIELD: welding. SUBSTANCE: according to this method temperature and duration of calcination are selected depending on basicity of flux using the formula: T=211+308ln(1+B); τ=1,63+0,81ln(2,1+B), where T - calcination temperature C, τ - duration of calcination, h; B - flux basicity. This method provides evacuation of moisture from flux without its overheating and worsening of welding properties. EFFECT: enlarged operating capabilities. 2 tbl
