Molten steel is refined in LF furnace,which can effectively desulfurize and accurately control composition,but-molten steel silicon mass fraction due to silicon addition in refining process exceeds standard requirements.By strictly con-trolling tapping slag of converter,without silicon containing alloy and deoxidizer,refining cycle of LF furnace is controlled within 32 min,mass fraction of refined yellow white slag(FeO)+(MnO)is 0.75％～1.5％,silicon increase in molten steel during refining is not more than 0.008％,and silicon mass fraction of wire rod meets internal control requirements.High-speed wire rod rolling mill spinning temperature is 930～950℃,roller speed is not greater than 0.3 m/s,and it is covered with an insulation cover for insulation and slow cooling.Chemical composition and mechanical properties of H08E wire rod developed and produced are stable.
