Background

The cold-pressed pellet is a processing process for preparing the finely ground concentrate into a block material which can meet the smelting and ball pressing requirements, namely, under a certain pressure, the powder material is pressed into a light block material with a certain shape, size and density in a model. After the block is formed, corresponding consolidation is generally needed to make the block become a block with higher strength. The process is as follows: the prepared raw materials are mixed and evenly mixed according to a certain proportion, green pellets with certain size are prepared by a pelletizing device, and then the green pellets are dried and roasted or subjected to a plurality of physical and chemical changes by other methods to be hardened and agglomerated. The product obtained is called pellet. After the powder material is fully mixed with solid reducing agent (coal powder and coke powder, etc.) and proper adhesive, the mixture is pressed by ball press to obtain the invented carbon-containing pellet or carbon-containing cold-pressed pellet, so that it is called carbon-containing pellet. Among the technologies of using coal instead of coke, carbon-containing pellets are attracting attention.
