During the whole production process, ironmaking, steelmaking, hot steel rolling, pickling and alkaline cleaning are not needed, as is known to all, the ironmaking and steelmaking and other processes are performed at the temperature of about 1600 DEG C, and pollution caused by ironmaking, steelmaking, steel rolling, pickling and alkaline cleaning is very serious. In the method, reducing is performed with H2 and / or CO gas,the highest temperature is about 1200 DEG C, three wastes are subjected to ultra-low emission and zero emission, and compared with a traditional ferrous metallurgy and steel powder rolling process, the method is simpler, more environmentally-friendly and more energy-saving.
