FIELD: paint-and-varnish industry; production of the heat-resistant paints for metallurgy.

SUBSTANCE: the invention is pertaining to field of the paint-and-varnish industry, in particular, to production of the heat-resistant paints capable to withstand the temperatures of hot metal in the steelmaking and rolling shops of metallurgical complexes. The purpose of the invention is to develop the heat-resistant paint with a capability of its application on the metals, in particular, to apply the marks on the hot metal and to withstand the temperatures of 60-300°C. The invention provides the paint ecological purity, reduction of its net cost and expenditures for its manufacture and usage. The solution of the task in view is achieved due to the fact, that the paint contains compounds based on the oxides of metal - the powdery aluminum oxide, silicon-containing substance - the soluble liquid sodium or potassium glass and water.

EFFECT: the invention ensures production of the heat-resistant paint used for applications of the marks on the metals, ensures its ecological purity, reduction of its production net cost and expenditures for its usage.
