Method of manufacturing a -2CaO SiO2

摘要

Purity to be high, the production manner of 2CaO SiO_{2 where you} can obtain the product of the quality where furthermore, productivity is high industrially, stabilizes is offered. To designate CaO and SiO₂ as the main component, CaO/SiO2 mol ratio 1.8 - 2.2, after the 1000 heating, Al₂ O content of total of₃ and Fe₂ O₃ 5 mass % under, the raw materials which granularity of the raw materials 90 mass % corning do those which are made above in 150 millimicron penetration, corning they do, the magnesia - spinel brick, Al₂ O₃ content factor 85 mass % the alumina quality brick and the carbonized Kay character brick above, the magnesia - spinel mortar, and Al₂ O₃ content factor 85 mass % the group which consists of the alumina quality mortar aboveThe empty at the traffic circle kiln which at least uses the brick or the mortar of 1 where it is chosen genera or more for the inside of the burning zone, it calcines at burning point temperature, 1350 - the 1600 it features that 40 millimicron penetration after the dusting is 85% or more.
