| description | The invention provides a low-dust iron and steel metallurgy method. The low-dust iron and steel metallurgy method comprises the following steps that S1, raw materials are selected, specifically, concentrate powder with the Fe content being greater than or equal to 65% or crushed rolled steel oxidized scale, water and a binder are selected for pelletizing; S2, reduction is conducted, specifically,the raw materials are fed into a belt-type reduction furnace, a catalyst is added, CH4 is converted into H2 and CO through the catalyst at the high temperature, ferric oxide is subjected to reductionsmelting, the temperature is set to be 900-1050 DEG C, the heating time is 1-3 h, the thickness of a material layer is 20-30 mm, thus metal iron particles are obtained, other metal elements in the ferric oxide exist in the metal iron particles in the form of MxOy, and M is the other metal elements; S3, cold pressing or hot pressing is conducted, specifically, the metal iron particles at the temperature of 50-800 DEG C are |
