FIELD: metallurgy.
SUBSTANCE: method includes mixing the periclase-containing powders, filling the moulding mixture into a mould and sealing with vibrocompression. Before mixing, the powders are preheated to a temperature of 70-100°C, the mixing is carried out at a temperature of 90-100°C, during which a binder is introduced in the form of coal tar, heated to a temperature of 110-120°C, and the compaction by vibration-pressing is performed at a pressure of 1.8-2.5 MPa, vibration with a frequency of 3000-6000 rpm and an amplitude of 1.0-2.0 mm.
EFFECT: manufacturing non-fire, tar-periclase refractory products with specified mechanical characteristics.
