Introduction to basic refractories

Basic refractories to CaO, MgO refractory alkaline earth oxides as the main ingredient. Usually refers to the magnesia refractories, refractory and calcareous dolomitic refractories.
Mainly in the following categories:
(1) strongly alkaline brick, magnesium carbon brick, brick and lime dolomite refractory;
(2) alkaline chrome magnesia refractories, refractory forsterite and magnesium aluminum, magnesium and chromium spinel refractories.
Basic refractories for basic slag at high temperatures, resistance to strong alkaline flux, but the acidic slag, refractory acid or acid flux from a chemical reaction. Mainly used in steel-making furnaces and basic non-ferrous metal smelting furnaces and cement kilns.
