The invention relates to a roll barrel of a low-cost nonmagnetic electric stirring roll, which is characterized in that the roll barrel is made of a multielement stainless alloy-steel that is ZGOCr25Ni20Si2MoBV; the main alloying elements have the contents by weight percentage that C is 0.05 to 0.08, Cr is 24 to 26, Ni is 18.5 to 20, Mn is 1.5 to 2, Mo is 1.2 to 2, Ti is 1.5 to 2, Si is 1.2 to 2, Ais is 0.15, Cu is 0.03, B is 0.015, W is 0.014, and the others are Fe; a technological method for manufacturing the roll barrel comprises a roll-blank smelting procedure, a centrifugal blank casting procedure, the heat treatment of the roll barrel, and the machining molding. The roll barrel solves the problems that the roll barrel is imported for a long time, the price is expensive, and the production is influenced when failure occurs because the time for offshore purchases is long; the roll barrel is mainly used on the electric stirring roll used for silicon iron production on a continuous casting ...
