Many adverse trends being faced by the reaching mature blast furnace process, such as increasing ratio of dependence on foreign iron ore and smaller particle size iron ore and increasing depletion of coking coal resource, have restricted the healthy development of iron and steel industry. However, the fluidized bed process for ironmaking with obvious advantage in China can be hoped to make up for their weaknesses. In this paper the researching progresses of sticking problem impeding commercialization are analyzed. Existing fluidized bed processes selected different projects in the key link for avoiding the difluidization, but their current selections lead to the exorbitant costing , so as to the costing of all ironmaking process are be rebounded. So reducing the cost of restraining sticking is the key of the industrialization of fluidized bed process for reduction.
