Abstract
Recently with the aim of increasing the stability of converter linings there has been extensive use of a new class of synthetic magnesia modifiers that are added directly to the converter melt during steel melting. The chemical composition of modifiers and method for their preparation are provided. The basis of the magnesia modifiers is MgO oxide and its compounds. Modifier properties (density, open porosity) are studied in relation to a change in specimen heating and the mineral composition of modifiers of different chemical composition, and the change in the structure of modifier specimens during heating is examined. The mechanism of modifier dissolution in molten slag is suggested.
