The invention discloses a chrome-free configuration structure of an inner kiln refractory material of a rotary cement kiln. The chrome-free configuration structure of the inner kiln refractory material of the rotary cement kiln is characterized by comprising bottom-layer castable, highly abrasive bricks, MS2T magnesia spinel bricks, MS1C magnesia spinel bricks, MS4TC magnesia spinel bricks, red guimo bricks, guimo bricks and sealing castable. The chrome-free configuration structure of the inner kiln refractory material of the rotary cement kiln has the advantages that spinels have sealed lattice structures, after filling by suitable phases, calcium oxide ions are prevented from entering lattices, chemical reaction between cement clinker and the spinels only occurs on surfaces of the spinels, and compared with chemical erosion on other types of spinel magnesia bricks with open lattices, the chemical erosion of clinker on the spinel magnesia bricks with the sealed lattices can be remarkably lowered. 8-12% of waste chrome emission can be reduced in terms of each rotary cement kiln.
