| description | The invention relates to a production method of a pure iron rod DT4C for a high-permeability electromagnetic cell. Steel comprises the following chemical components in percentage by weight: less than or equal to 0.003% of C, less than or equal to 0.005% of Si, 0.10-0.20% of Mn, less than or equal to 0.012% of P, less than or equal to 0.005% of S, 0.70-0.80% of Al, less than or equal to 0.003% of Ti and the balance of Fe and inevitable impurities. According to the process route, converter + LF + RH + continuous casting + bar rolling is adopted, and the problem that the content of silicon and P in molten steel is high in the production process is solved through the LF slagging-off process under the condition that pretreatment for S removal is not conducted; a ladle furnace is adopted for producing reducing slag to remove S, so that the problem of S content in molten steel is well solved; the RH adopts high-oxygen-position C removal, so that the problem of ultra-low carbon is solved; rH top slag modification and |
