A rotary hearth furnace iron-making method utilizing biomass carbon-containing pellets to serve as a raw material belongs to the field of ferrous metallurgy and relates to a rotary hearth furnace iron-making process using the biomass to serve as iron-making fuel and a reducing agent. The process comprises the steps, utilizing reproducible carbon neutral biomass coke powder to replace pulverized coal, enabling the biomass coke powder and the iron ore powder to be matched with each other according to C / O=1.1-1.4, adding an appropriate binder, evenly mixing to make pellets, and enabling the pellets to enter a rotary hearth furnace to be heated and undergo reduction so that a metalized pellet is obtained. The biomass coke has carbon neutral and can fundamentally reduce discharge of pollutantssuch as CO2 caused by coal consumption. The impurity content of the biomass coke is little, the problem that sulphur content of products caused by coal using is too high is solved, and the comprehensive quality of the products is improved. The energy in the preparation process of the biomass coke can be supplied by biomass itself, and green circulating production is substantially achieved. The rotary hearth furnace iron-making method expands energy sources for rotary hearth furnace iron making, reduces production cost, improves product quality and production efficiency and reduces environmental pollution.
