Изобретение относитс  к обработке стали путем нанесени  электроизол ционных покрытий и может быть использовано в металлургии.The invention relates to the processing of steel by applying electrically insulating coatings and can be used in metallurgy.

Цель изобретени  - увеличение текучести , смачивающей способности, снижение температуры полимеризации раствора и повышение магнитных - свойств стали.The purpose of the invention is to increase the flowability, wetting ability, decrease the solution polymerization temperature and increase the magnetic properties of the steel.

Раствор готовили следующим образом .The solution was prepared as follows.

Размешивали оксид магни  в воде до получени  однородной суспензии, в которую затем небольшими порци ми добавл ли ортофосфорную кислоту. После полного растворени  оксида магни  раствор нагревали до 70-90°С и добавл ли гидроксид алюмини , после растворени  которого добавл ли борную кислоту и водорастворимые соединени  натри  Na3PO+, NaHC03, Na7C03. Полученный раствор охла/кдали до 10-40вС.The magnesium oxide was stirred in water until a homogeneous suspension was obtained, to which orthophosphoric acid was then added in small portions. After complete dissolution of the magnesium oxide, the solution was heated to 70-90 ° C and aluminum hydroxide was added, after dissolving of which boric acid and water-soluble sodium Na3PO +, NaHC03, Na7C03 were added. The resulting solution is cooled / diluted to 10-40 ° C.

Покрытие наносили на электротехническую сталь, котора  после обработки в растворе предлагаемого состава, поступала в проходную печь и отжигалась при 600-850°С в течение 0,5- 3,0 мин.The coating was applied to electrical steel, which, after being treated in a solution of the proposed composition, entered the continuous furnace and annealed at 600–850 ° C for 0.5–3.0 minutes.

Качество покрыти  на стали определ ли на отобранных от рулонов образцах по стандартным методикам.The quality of the coating on steel was determined on samples taken from coils using standard methods.
