Calcined dolomite and quick lime are both essential inputs for steelmaking and refractory applications, but they are not interchangeable.
Quick lime (CaO) is valued for high reactivity, slag conditioning, and sulphur control. Calcined dolomite, rich in both calcium and magnesium oxides, supports slag basicity and refractory protection where MgO is required.
Procurement decisions should weigh chemistry, size fraction, reactivity, and furnace practice. Matching product chemistry to process targets reduces consumption and improves steel quality consistency.
