The invention relates to a method for reinforcing preparation and reduction of carbon-containing
pellets in
iron ore. The method for reinforcing preparation and reduction of the carbon-containing
pellets in the
iron ore comprises the following steps that (1) the
iron ore, a
reducing agent, a bonding agent and an additive are prepared according to a certain proportion; (2) prepared mixtures are sent into a
ball mill to be crushed, fine ground, evenly mixed and the like, so that fine-sized evenly-
mixed materials are obtained; (3)
pelletizing or briquetting is conducted by means of the fine-sized evenly-
mixed materials, so that the carbon-containing
pellets in the iron ore are obtained; and (4) the prepared carbon-containing pellets in the iron ore are subjected to reducing
roasting treatment, and thus metallized pellet products can be obtained. According to the method for reinforcing preparation and reduction of the carbon-containing pellets in the iron ore, in the way that the raw materials including the iron ore, the
reducing agent, the bonding agent, the additive and the like enter the mill simultaneously after being prepared, the dual effects of fine
grinding and sufficient and even mixing of the raw materials are achieved at the same time in the single ore
grinding procedure, and the procedure links of fine
grinding raw materials separately in advance, then preparing the raw materials in proportion and finally conducting even mixing of traditional operation are greatly simplified; and the quality of the carbon-containing pellets in the iron ore is remarkably improved, and the subsequent reduction process is reinforced.
