| description | The invention discloses a method for smelting nickel-containing molten steel through a converter and the nickel-containing molten steel. The method comprises the steps that nickel-containing alloy or nickel elementary substance is added into molten iron, oxygen is supplied to the molten iron through an oxygen lance, calcium-containing flux is added in batches, the lance position of the oxygen lance is 150-240 cm, the oxygen flow is 700-900 Nm < 3 >/min, and under the condition that oxygen supply is a first oxygen step, the lance position of the oxygen lance is controlled to be 200-240 cm, and the oxygen flow is controlled to be 800-900 Nm < 3 >/min; under the condition that oxygen supply is the second oxygen step, the lance position of the oxygen lance is controlled to be 180-195 cm, and the oxygen flow is 750-870 Nm < 3 >/min; under the condition that oxygen supply is performed in the third oxygen step, the lance position of the oxygen lance is controlled to be 180-195 cm, and the oxygen flow is 730-780 Nm |
