The invention discloses a method for measuring the solid solubility of rare earth elements in steel, which comprises the following steps: under certain conditions, carrying out electrolytic treatment on a sample containing an RE element, then collecting electrolyte, filtering out undissolved substances, and measuring the content of the RE element in the electrolyte, and at the moment, the content of the RE element dissolved in the electrolyte is the solid-solution RE element in the steel. The invention aims to provide the method for measuring the solid solubility of the rare earth element in the steel, the solid solubility of the rare earth element in the steel is detected, the efficient balanced utilization of the rare earth element in the steel is improved, the content of the solid solution rare earth is measured by considering a chemical separation method, and the application of the rare earth element in the steel can be effectively improved. The influence and improvement effects of rare earth elements on
