Calcium Zirconate as the Secondary Phase of Magnesia Refractories for Cement Rotary Kiln

Article Preview

Abstract:

The paper describes formation of the phases in magnesia-zirconia refractories due to reaction with the cement furnace charge in a form of pre-calcined meal or Portland clinker containing sulphur and chlorine in a different content at the temperature 1300°C and 1450°C. The studies were carried out by using the coating test. The microstructure changes of the contact zones between coating and the brick were studied by the scanning electron microscopy, SEM, coupled with EDS. The temperature dependence of reactivity the pre-calcined meal and Portland clinker in relation to the magnesia-zirconia bricks has been documented and discussed.
