The utility model discloses an oxygen-enriched side-blown molten pool smelting furnace which comprises a furnace wall and a plurality of air nozzles arranged on the furnace wall, the first molten poolis lower than the furnace wall, and a slope is arranged on the bottom surface of the first molten pool; the second molten pool is communicated with the first molten pool, the slope surface of the second molten pool is higher than that of the second molten pool, a metal outlet, a slag outlet and a plurality of heating rods are arranged in the second molten pool, the slag outlet and the heating rods are higher than the metal outlet, and the heating rods can release heat in the second molten pool. The method has the advantages that the slope can promote the melt to flow from the first molten pool to the second molten pool, and low-temperature condensation of the melt in the first molten pool is prevented. The heating rod can heat the upper-layer slag in the second molten pool, low-temperature condensation of the sla
