Abstract

The influence of both the moisture and atmosphere on the magnesia refractory strength properties is investigated in the article. The method increasing the magnesia refractory's moisture resistance by means of the phosphate binder impregnation is proposed. In accordance with the results it was defined that the most effective binder is alumina-chromium-phosphate binders (ACPB). The industrial tests of the tuyere area's lining in the horizontal converter of Kirovograd's Copper-smelting Works showed the 12‒15 % increase of the lining service life. The expediency was established for the impregnated refractories' using in the most wear-prone parts of the thermal vessels' lining such as the tuyere area, the orethermal furnace's slag-line area and the electric arcfurnace's cord units. Ill. 2. Ref. 3. Tab. 4.
