Process for preparing semisolid steel blank by using radial forging strain induction method

The invention discloses a process for preparing a semisolid steel blank by using a radial forging strain induction method. The process comprises the following steps: firstly, preheating a steel rod material, performing radial forging on the steel rod material, performing secondary remelting on the blank after radial forging, and finally preparing the semisolid steel blank. By adopting the process, semisolid steel blanks which are uniform in tissue and small in micro defect can be prepared in batch, and the process is simple in procedure and easy to operate.
