Iron aluminate cement clinker, preparation method thereof and iron aluminate cement

The invention relates to an iron aluminate cement clinker, a preparation method thereof and iron aluminate cement. Relates to a cement production technology. The cement clinker comprises the following minerals in percentage by mass: 30-50% of anhydrous calcium sulphoaluminate, 35-40% of dicalcium silicate and 10-30% of calcium aluminoferrite, and the total content of the three minerals is not less than 92%. The cement clinker comprises the following raw materials in percentage by mass: 10-30% of steel slag powder, 20-30% of bauxite, 40-50% of limestone, 7-10% of anhydrite and 0.1-1% of lithium carbonate. The content of MgO in the steel slag powder is not higher than 10%, and the content of MnO is not higher than 3%. The content of calcium oxide in the limestone is not lower than 50%, the content of aluminum oxide in the bauxite is not lower than 55%, the content of sulfur trioxide in the anhydrite is not lower than 45%, the content of iron oxide in the steel slag powder is not lower than 20%, and the content
