FIELD: metallurgy.
SUBSTANCE: method includes formation of a metal shell of U-shaped profile, filling of U-shaped profile of metal shell with filler and squeezing of movable metal shell with filler. Pure calcium melt is used as filler flowing out of crucible at temperature of 900-1000°C, which fills the metal shell, after the filling the longitudinal edges of U-shaped profile of tubular metal shell are squeezed overlapped with subsequent cooling, at that the filling with melt, formation of squeezing and cooling of tubular shell is carried out under inert atmosphere of argon.
EFFECT: high content of active calcium in solid monolithic state without oxygen and increased filling factor, reduced consumption of wire required for treatment of specified amount of metal.
