Embodiment 1
[0025] Embodiment 1: A high-efficiency production method for Ф12mm wire rods, comprising the following steps:
[0026] 1) Rough smelting: Heating the converter to above 1100°C by step heating, and then refining the raw material of the wire rod through the converter to obtain rough smelting molten steel. The chemical composition and mass percentage of the wire rod in step 1 are: C: 0.015% , Ni: 35%, S: 0.003%, P: 0.003%, Al: 0.030%, Cr: 30%, the rest is Fe and unavoidable impurities, the metal oxide is specifically aluminum oxide, the rare earth element is Re, The mass percentage of aluminum oxide is 0.05%, and the mass percentage of rare earth element is 35%;
[0027] 2) Refining: Pass the crude molten steel obtained in step 1 into a refining furnace for refining to obtain refined molten steel;
[0028] 3) Continuous casting: the refined molten steel obtained in step 2 is rolled by the continuous casting machine, and the whole process of continuous casting is protected and po...
