Description

Изобретение относится к производству эмалей для покрытия, преимущественно, изделий из чугуна. The invention relates to the production of enamels for coating, mainly, cast iron products.

Известна эмаль, содержащая следующие компоненты, мас. % : SiO2 45-48; В2О3 5,2-7,4; Al2O3 4-6,1; СаО 3,2-3,2; Na2O 11,4-17; К2О 4-6,5; TiО2 3-9,2; Zi2O 2,9-3,8; F 1-4, Sb2O3 3,8-7,8. Эмаль имеет растекаемость 42-45 мм, температура обжига эмали 850-900оС.Known enamel containing the following components, wt. %: SiO 2 45-48; B 2 O 3 5.2-7.4; Al 2 O 3 4-6.1; CaO 3.2-3.2; Na 2 O 11.4-17; K 2 O 4-6.5; TiO 2 3-9.2; Zi 2 O 2.9-3.8; F 1-4, Sb 2 O 3 3.8-7.8. The enamel has a spreadability of 42-45 mm, the enamel burning temperature is 850-900 о С.

Цель изобретения - повышение растекаемости, снижение температуры обжига и себестоимости. The purpose of the invention is to increase the spreadability, reducing the firing temperature and cost.

Для этого эмаль содержит, мас. % : SiO2 45-48; В2О3 4-5; Al2O3 4,5-6,1; СаО 5-8,2; Na2O 15-17,3; К2О 4-6,5; TiO2 1-1,5; Li2O 1,5-2; Sb2O3 1-2; Fe2O3 5,8-6,5; ZnO 5-5,7.For this enamel contains, by weight. %: SiO 2 45-48; B 2 O 3 4-5; Al 2 O 3 4.5-6.1; CaO 5-8.2; Na 2 O 15-17.3; K 2 O 4-6.5; TiO 2 1-1.5; Li 2 O 1.5-2; Sb 2 O 3 1-2; Fe 2 O 3 5.8-6.5; ZnO 5-5.7.

В таблице приведены примерные составы эмали. The table shows exemplary enamel compositions.

Растекаемость эмали составит, мм: для 1 состава 50±2; для 2 и 3 составов 55±2. Обжиг эмали может проведен при 800оС. Снижение содержания окислов дорогостоящих элементов и введение в состав эмали Fe2O3 и ZnO значительно уменьшают ее себестоимость.Enamel spreadability will be, mm: for 1 composition 50 ± 2; for 2 and 3 compositions 55 ± 2. Firing the enamel can held at 800 ° C. Reduction of the oxides of expensive elements and the introduction of the enamel Fe 2 O 3 and ZnO significantly reduce its cost.
