description The invention relates to the technical field of steelmaking, in particular to a production control method for reducing the hydrogen content in steel of a coastal steel mill, which comprises the following steps: (1) strictly executing a waste steel baking system by a converter; (2) reducing the water content of lime and graphite carburant entering the furnace; (3) in the LF refining procedure, small-particle lime is evenly spread on the surface of the slag and baked at high temperature for 3-5 min, the small argon flow is controlled, submerged arc operation is well conducted during electric heating, and components are qualified after one-time adjustment; and (4) when the end point oxygen of the converter is greater than or equal to 600ppm, the dosage of small-particle lime is increased. According to the production control method, the hydrogen content of the LF single-linkage steel grade is controlled within 4 ppm, the hydrogen content of the LF + RH duplex steel grade can be controlled within 2 ppm, the hydrog
