The invention discloses a method for smelting stainless steel containing Ni, which is characterized in that the method mainly comprises the following steps: low-grade nickel-containing chromium-containing ore is dried and then is sintered; the sintered ore is smelted into molten iron containing the Ni in a blast furnace; the molten iron is subject to pretreatment desulfurization and dephosphorization to form a stainless steel mother solution; iron alloy is melted in an electric furnace; the refining is performed in a stainless steel smelting furnace and a VOD furnace; and a stainless steel billet is obtained by continuous casting. The low-grade nickel-containing chromium-containing ore is used to substitute for chromium and nickel alloy to smelt the stainless steel, so the cost for the stainless steel is reduced greatly. At the same time, the method can fully utilize the low-grade ore, ensure that the idle scarce resource is fully utilized, and can reduce cost.
