Method for comprehensive metallurgy of powder metallurgy and high-phosphorus oolitic hematite

The invention discloses a powder metallurgy and high-phosphorus oolitic hematite comprehensive metallurgy method, which adopts a short-process steelmaking process route of powder metallurgy and high-phosphorus oolitic hematite comprehensive metallurgy. The high-purity pure iron molten steel is prepared from the original ecological high-phosphorus oolitic hematite through a production process of reducing iron powder solid carbon/H2 reduced iron oxide through powder metallurgy and a corresponding continuous melting and refining short-process steelmaking process, and a set of brand-new, complete and systematic high-quality short-process metallurgical process of green low-C, low-S, low-P, low-impurity and high-purity molten steel is formed. By utilizing the method, the high-purity steel base material with low C, low S, low P and low impurities can be prepared by simply applying the high-phosphorus oolitic hematite on a large scale, and the steel quality is greatly and fundamentally improved. 本发明公开了一种粉末冶金+高磷鲕状赤铁矿综
