Description

Изобретение относится к производству эмалей, которые могут быть использованы преимущественно для покрытия изделий из чугуна и стали.The invention relates to the production of enamels, which can be used mainly for coating products from cast iron and steel.

Известна эмаль, содержащая, мас. %: SiO2 38,0-50,0; B2O3 9,0-14,0; Na2O 19,0-23,0; MgO 2,0-3,0; P2O5 3,0-5,0; TiO2 0,6-1,0; Al2O3 3,0-5,5; CaF2 3,0-5,0; Fe2O3 0,1-0,5; CaO 3,0-5,0; K2O 0,3-1,0; F2 2,0-4,0 [1]. Ударная прочность такой эмали составляет 0,7-0,8 Дж.Known enamel containing, by weight. %: SiO 2 38.0-50.0; B 2 O 3 9.0-14.0; Na 2 O 19.0-23.0; MgO 2.0-3.0; P 2 O 5 3.0-5.0; TiO 2 0.6-1.0; Al 2 O 3 3.0-5.5; CaF 2 3.0-5.0; Fe 2 O 3 0.1-0.5; CaO 3.0-5.0; K 2 O 0.3-1.0; F 2 2.0-4.0 [1]. Impact strength of such enamel is 0.7-0.8 J.

Задачей изобретения является повышение ударной прочности эмали.The objective of the invention is to increase the impact strength of enamel.

Технический результат достигается тем, что эмаль, включающая SiO2, MgO, TiO2, Al2O3; CaF2; Fe2O3; CaO; K2O, дополнительно содержит NiO и Cu2O, при следующем соотношении, мас. %: SiO2 32,0-38,0; MgO 12,6-14,0; TiO2 06-1,0; Al2O3 3,0-5,5; CaF2 3,0-5,0; Fe2O3 6,0-8,0; CaO 13,0-15,0; K2O 14,0-16,0; NiO 4,5-6,1; Cu2O 0,8-1,5.The technical result is achieved in that the enamel, including SiO 2 , MgO, TiO 2 , Al 2 O 3 ; CaF 2 ; Fe 2 O 3 ; CaO; K 2 O, additionally contains NiO and Cu 2 O, in the following ratio, wt. %: SiO 2 32.0-38.0; MgO 12.6-14.0; TiO 2 06-1.0; Al 2 O 3 3.0-5.5; CaF 2 3.0-5.0; Fe 2 O 3 6.0-8.0; CaO 13.0-15.0; K 2 O 14.0-16.0; NiO 4.5-6.1; Cu 2 O 0.8-1.5.

Варку фритты эмали осуществляют при температуре 1430-1470°C. Расплав гранулируют в воду. Гранулы размалывают мокрым способом до прохождения через сетку 0056. Полученный шликер с влажностью 44-50% наносят (напыляют) на подготовленную поверхность изделий и закрепляют оплавлением.Enamel frit is cooked at a temperature of 1430-1470 ° C. The melt is granulated into water. The granules are milled wet until passing through a mesh 0056. The resulting slurry with a moisture content of 44-50% is applied (sprayed) to the prepared surface of the products and fixed by reflow.
