摘要：Refractory materials (typically refractory bricks) having the exposed workingsurface treated to form a silica sand glazed surface for their utilization in iron orereduction reactors, for example of the moving bed type, fluidized bed type, rotary kilns,or the like, and method and apparatus for treating refractory bricks before installation aswell as for treating refractory linings already installed in existing iron ore reductionplants, which produce direct reduced iron (DRI), prereduced iron ores, or the like. Someoperational problems, involving adherence and buildup of aggregates from smallmetallic iron particles on the refractory lining of said reduction reactor, are minimizedwith a corresponding decrease in operating costs and an increase in the availability of theDRI producing plant.
