Method for directly preparing thin strip from ferric oxide

The invention relates to a method for directly preparing a thin strip from ferric oxide. The method comprises the following steps of weighing super iron concentrate powder/iron oxide powder with the content larger than 71.5% and an organic binder according to the proportion, mixing in a mixing machine for 30-60 min, pelletizing, sequentially performing preliminary rolling and winding, reducing, rolling and winding for multiple times, and finally sequentially performing secondary sintering, bright heat treatment, finishing and winding, thereby obtaining the thin strip. 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 i
