Method for centrifugally removing harmful elements and impurities in iron-containing mixture

The invention relates to a method for centrifugally removing harmful elements and impurities in an iron-containing mixture. The method comprises the following steps that (1), the molten mixture at thetemperature of exceeding 650 DEG C is put into a centrifugal rotating device; (2), the centrifugal rotating device completely contains the molten mixture, and intermetallic compound crystals are precipitated and grow up; (3), centrifugal separation treatment is carried out on the molten mixture manufacturing supergravity field in the device; and (4), various products are stripped by using a manual or mechanical method, and subsequent remelting and ingot casting or refining are carried out. According to the method, substances such as solid-phase compounds are precipitated when the mixture is subjected to liquid phase cooling, the mixture and the impurities are separated by means of the supergravity effect generated by centrifugal rotating motion by utilizing the difference between the density of the intermetallic
