The invention belongs to the technical field of chemical substance analysis methods, and discloses a method for narrowing and controlling chemical components in the smelting process. Narrow control is introduced in chemical component inspection, a plurality of control points are set, the first-pass yield of the chemical components of the discharged finished product steel is guaranteed to be 98% or above through upper and lower limits, the accuracy of chemical component inspection is achieved, the stability of the steel quality is improved, the product quality control capacity is enhanced, and standardized operation and process quality management and control are enhanced. By adopting the control method disclosed by the invention, the control level of chemical components can be greatly improved, the production process and the product quality are stable, and the requirements of accurate component control and user personalization are met. 本发明属于化学物质分析方法技术领域，公开了一种冶炼过程化学成分窄控的方法。本发明化学成分检验中引入窄控制，设定多个控制点，通过上下限，保证出炉成品钢材
