The effect of moisture and environment on magnesia composition refractory strength properties is studied. A method is proposed for increasing refractory moisture resistance by using impregnation with phosphate binders. According to results of the work alumochromium phosphate binder (ACPB) is most effective. Industrial testing of a lining impregnated with this binder for the tuyere belt of a Kirovgrad Copper Smelting Plant horizontal converter showed an increase in service life by 12 – 15%. The expediency of using impregnated refractories in the most worn parts of heating unit lining is established, such as a converter tuyere zone, slag belt of ore-smelting furnaces, and electric furnace flex assemblies.
