The present invention relates to enamel or a combination of two diamond enamels, in particular Beagle, which are used for anti-corrosion protection of low-carbon steel products, worked in aggressive environments at elevated temperatures , in the case of washer equipment, piping, parts for washing machines, water heaters, reactors, etc. It is known to have no enamel enamel intended for use in alkali medium containing in mass silicon dioxide 35-49 parts of aluminum trioxide 3-6 , double-chain trioxide 8,6-17,2, sodium oxide 14-21, cal oxide oxides 2-3.5, titanium dioxide 3.5-5.5 calcium oxide 2.5-7.5 decarboxylic acids 0.8-1.3, nickel oxide 0.010.2, manganese dioxide 0.1-0.0, 6 Dusophosphorus pentoxide 0, 8-2,6, fluorine 1,7-5,1, zirconium trioxide 3, S-5,2 / 1L Deficiency of the described enamel is its insufficient acid resistance: loss of weight after 4 hours boiling in The closest to the composition proposed is the enamel-free enamel containing, by weight, of silica 55-70, alumina 0, 5-5, 2-membered trioxide 2- 6, sodium oxide 8-15, potassium oxide 1-6, lithium oxide 1-8, titanium dioxide 0.5-8, calcium oxide 5-10g of oxide 0, 4-1, nickel oxide 0, 55-1, calcium fluoride 2-8 / ice oxide up to 4 / danganous dioxide to 4/2 / Deficiency of the described enamel is its limited application, only acidified aggressive media. The object of the invention is to provide an enamel, or a combination of olefins, in particular bean gum, with increased acid and alkali resistance and good adhesion to the metal surface at elevated temperatures. The consciousness of the invention consists in the fact that the basic enamel is: silicon dioxide, tribasic trioxide, sodium succinate, titanium dioxide, calcium oxide, cobalt oxide, nickel oxide, and the like. And zirconium dioxide of from 0.5 to 10% by mass, such as silica, 50-70% silicon dioxide, two alumina 0.5 -7, Dibasic Trioxide 1-12, Sodium Oxide 8-20, Titanium Dioxide 0.5-5, Calcium Oxide 3-10, Cobalt Oxide 0.4-1, Nickel Oxide 0.5-1.5 and, if desired, contains in calcium, boron to 8, potassium in oxide up to 6, copper oxide up to 4, lithium oxide up to 5, manganese dioxide up to 4, zinc oxide, oxide up to 4, double phosphorus pentoxide up to 5, bifenthalithrioxide to 8, barium oxide up to 4. Melting the enamel takes place at temperatures of 1250-1300 with subsequent granulation of the melt in cold water. From the frit obtained, an enamel tank with milling additives and fillers in different proportions is prepared directly on pre-prepared metal surfaces by known methods: injection molding or immersion and watering. After drying, the coating rises at a temperature of 820-880 ° C . C. Additional enamels are characterized in that they contain in the silicon dioxide 35-52, alumina 2,2-7,5, bicorphous trioxide, in the molten recipe, in a proportion of different proportions. 13-21, sodium oxide 15-22, calcium oxide 1-12, cobalt oxide 0.3-1, nickel, oxide 1- 2.5, and, in the case of waste, calcium fluoride to 8.5, titanium dioxide to 2, potassium oxide to 4, lithium oxide to 3, manganese dioxide to 2, zirconium dioxide to 3, barium oxide to 4, titanium dioxide to 2. The object of the invention is to improve the quality of the enamelled articles in terms of increasing the service life in aggressive environments with variable pE and elevated temperatures. The invention is illustrated by the following examples: From an enamel frit containing in mass silica 60, alumina. 5 g of cobalt oxide, 9 g of nickel oxide, 0.6 g of calcium fluoride, 10 g of sodium fluoride, 10 g of sodium peroxide, 10 g of potassium peroxide, zirconium dioxide 5.4, two phosphorus pentoxide 1.60, prepare an enamel pulverizer according to the following recipe in mass. parts.
